There are two ways that you can access emails.
POP3 (Post Office Protocol 3) is the traditional delivery method which has been used for many years. Messages are delivered to your web mail server, when your selected device program (typically Outlook) on your PC/Mac/laptop requests a download (send/receive action) the message is delivered to your in-box. You therefore have the entire message (and attachments) sitting on your PC/Mac/laptop so you can archive/reply/forward/delete – in other words it is up to you what you do with it.
Advance settings in most email programs will also allow you to keep a copy of the message on the server but if this is not pre-set the message is automatically deleted from the server when delivered. By keeping a copy of your messages on the server other PC/Mac/laptops/mobile devices can also receive the messages.
The other method of email delivery is IMAP (Interactive Mail Access Protocol). IMAP mail is delivered to the server in the same way as POP3 and then you connect to the server to see your mail. The mail is NOT stored on your local device but remains on the server.
IMAP allows you to access your mail from different devices, usually mobile phones hence its increased popularity. When the message is delivered using IMAP only the header (title/sender info) is visible, when you then click on the email it delivers the content but leaves a copy on the server.
You do not require an internet connection to view your downloaded emails
emails are not saved on the server (unless you activate the advance settings to save a copy) therefore not so likely to be lost should the server crash
server disk usage is minimal
available from any machine you use to access from (account/password required)
messages are stored on the server, so your email cannot be deleted/destroyed if your computer should crash, be stolen, or destroyed
Not available to other devices (unless advance settings are actioned)
Requires 3rd party applications for delivery (ie: Outlook)
You are relying on a 3rd party to archive your messages
Server space is limited
Servers holding your messages are not backed up
You require an internet connection to view your emails
Emails can be deleted if you stop paying the hosting fee
I recently went to Orlando. Before I left I emailed important info to my Android phone (IMAP), when I arrived they had been deleted, when I got back they reloaded!
Last year we lost our broadband connection for 4 weeks but I could continue to work because I had all my email instruction/messages on my local PC (POP3). During this time I had to use a 3G link and had a data download cap. Had I been using IMAP the costs would have increased.
POP3 is great for single, non-mobile devices but you need a 3rd party program to take delivery of your messages, or access to web mail (server). POP3 messages are also delivered in full to your device therefore you have more control over their archive and security
IMAP is the method of choice for mobile devices and multi-users but offers less control over message archiving and security. It also causes issues with high volume users because messages are stored on the mail server which can run out of space, or you could be charged for additional space.
Note: if you use a mobile device only for emails make sure you…
Delete old messages from the server
Use a static device (laptop, PC, Mac) to also store and back-up your messages
We do not back up our mail servers therefore the responsibility for archiving emails is with the client/user.

It’s crazy how much we rely on the internet. Our phones sync to it, we stream music, store things in the cloud, tablets, use wireless speakers…. and instead of one family computer, everyone has a laptop.
It’s important, more than ever, to have a strong home network. You shouldn’t have to stress about your network failing, or having “dead zones” in your house. Enter Linksys.
I set up a brand new network from top to bottom using Linksys. I used the Linksys WRT1900AC Dual Band Gigabit Wi-Fi Router.
In the box:
- 4 antennas
- Ethernet cable
- Power adapter
- Quick start guide
Installing this router was simple. I plugged it in and followed the prompts. There’s also an online guide here.
This powerful router has an array of features, including:
Ultimate Wi-Fi Coverage for Home
This stylish (and sturdy) blue-and-black router has the latest Wireless-AC platform along with the industry’s first four antenna configuration with a powerful 1.2 GHz dual-core ARM to provide exceptional signal strength and range to simultaneously support multiple users. It also has a dual eSATA/USB 2.0 and a USB 3.0 port to conveniently connect an array of devices and experience lightning-fast transfer speeds.
The WRT1900AC features exclusive SMART Wi-Fi software to monitor and control your network anywhere and anytime. It’s our first router to offer the Network Map smart tool, providing an intuitive at-a-glance view of your entire network.
The first router with 4 antennas
To provide strong, reliable Wi-Fi coverage throughout your home, the WRT1900AC features four external adjustable antennas that ensures your Wi-Fi signal is always at maximum strength, keeping everyone simultaneously gaming, downloading and streaming without lag. The antennas also enhance 2.4 GHz and 5 GHz simultaneous dual wireless bands performance for a strong, reliable Wi-Fi signal that eliminates dead zones even in multistory homes. The antennas arrive detached and are easy to install.
SMART Wi-Fi Software
With the SMART Wi-Fi, you can monitor and control a home network from anywhere, anytime using a PC or mobile device. I downloaded the app on my Android and love it. I used it to set up a secure guest network.
Have kids? You can set parental controls to restrict Internet access during certain times of the day. You can also monitor activity on your home network, add new devices, and check upload and download speeds. You can also prioritize which devices on your network receive the most bandwidth to reduce lag times and buffering when you’re streaming HD media or gaming.
I love it! The deadzones have vanished, and the signal is nice and strong. I like being connected and love that I can check stats on the go on my phone. If you’re in the market for a new router, this one is a good bet.

In the matter of:
Service Rules for the 698-746, 747-762, and 777-792 MHz Bands:
WT Docket No. 06-150
Implementing a Nationwide, Broadband, Interoperable Public Safety Network in the 700 MHz Band:
PS Docket No. 06-229
Implementation of the Commercial Spectrum Enhancement Act and Modernization of the Commission's Competitive Bidding Rules and Procedures:
WT Docket No. 05-211
Development of Operational, Technical, and Spectrum Requirements for Meeting Federal, State and Local Public Safety Communications Requirements Through 2010:
WT Docket No. 96-86
The Ad Hoc Public Interest Spectrum Coalition (PISC) applauds the Commission for including issues raised by PISC in the initial comment period.
The United States continues to fall further behind the rest of the world in broadband Internet access -- our markets lack the competition necessary to serve consumers with lower prices, faster speeds and universal access. Even as the broadband market has further consolidated -- leaving 96% of the market in the hands of two technologies -- our policy framework has only served to diminish opportunities for competition. The auction of the 700 MHz spectrum creates a new possibility for competitive broadband provision. It is imperative that we learn the lessons of the wireline market and make the appropriate policy corrections in the launch of the most promising wireless broadband markets.
The Commission simply cannot choose to let current market conditions and participants control the outcome of the upcoming auctions. To date, existing wireless broadband providers do not offer a useful "third pipe" for American consumers. Perhaps most importantly, this market for broadband capable mobile devices is dominated by the same incumbent firms that control the wireline broadband market. These incumbents make clear that they have no intention of offering broadband with the freedom to attach any device and run any application.
To foster real wireless broadband -- the fast, ubiquitous, and dynamic third pipe everyone agrees our country desperately needs -- PISC recommends that the Commission take the following steps both to ensure that new spectrum is offered on an open and nondiscriminatory basis and to bring in new entrants interested in challenging the current cozy wireless oligopoly and broadband duopoly:

West Sussex Country House
Case Study: West Sussex Country House
Infinite Projects had the unique opportunity to collaborate on a project involving the design and installation of a smart home in a West Sussex country house. The property, undergoing a complete redevelopment, required a sophisticated home automation system to control lighting, heating, and audio-visual systems. The client desired a modern and intuitive control system that combined voice and touch controls. Additionally, they sought to convert a barn into a home cinema. This case study explores the challenges faced, the solutions implemented, and the positive outcomes achieved through our partnership.
Client Requirements and Challenges:
The client envisioned a smart home system that would enhance their experience at the property, serving as a weekend getaway and a place extensively used during school holidays. However, the property suffered from an extremely slow internet connection, which discouraged family members from spending extended periods there.

Winston-Salem is one of nine communities in the United States to be designated a “Citizen-Engaged Community” by the Public Technology Institute.
The designation recognizes a city’s commitment to give residents multiple options for accessing government services and information, including the Internet, social media, interactive voice response, and call centers.
The eight cities and one city-county that received the designation for 2010–2012 were cited for using communications technology to set new standards for citizen participation, particularly in their use of centralized citizen contact centers that effectively use new technology for fast, friendly, and responsive service and that demonstrate accountability through performance reporting, not just for calls but also for service delivery.
City Link, the city’s call center, gives citizens a single number (727-8000) to call to request city services, report problems and make suggestions. The call center is staffed year-round 24 hours a day and receives an average of 23,771 calls a month.
The home page of the city web site prominently features a Citizen Service area and offers live chat for accessing services.
Also receiving the designation are Buffalo, N.Y.; Corpus Christi, Texas; Greensboro; Hampton, Va.; New York City; Miami & Dade County, Fla.; Philadelphia, and San Francisco.
The not-for-profit Public Technology Institute promotes innovation and collaboration for thought-leaders in government, and advances the use of technology to improve the management and delivery of services to the citizen. For more information visit www.pti.org.

Publisher's description - iNetwork Tools 1.0
iNetwork Tools is a collection of useful utilities that include the following:
1. Network Information - general information about your network such as: local ip, gateway ip, gateway mac, broadcast ip and external ip.
2. Whois - is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format.
3. NSLookup - tool available for many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. NSLookup uses the operating system`s local Domain Name System resolver library to perform its queries.
4. Traceroute - is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. Traceroute sends a sequence of Internet Control Message Protocol (ICMP) echo request packets addressed to a destination host. Determining the intermediate routers traversed involves adjusting the time-to-live (TTL), aka hop limit, Internet Protocol parameter. Frequently starting with a value like 128 (Windows) or 64 (Linux), routers decrement this and discard a packet when the TTL value has reached zero, returning the ICMP error message ICMP Time Exceeded.
5. Ping - is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.
6. Spam Check - this test will check a IP address against 13 DNS based email blacklists. (Commonly called Realtime blacklist, DNSBL or RBL). If your IP address has been blacklisted, some email you send may not be delivered. Email blacklists are a common way of reducing spam.
7. IP to Country - this tool displays the country of the IP address provided.
8. Port Scan - builtin remote port scanner.
9. Port Search - this tool search the port number provided to retrieve it`s common service name or application name.
10. Local Port Scan - this tool displays your local ports that are open. You will get an extra security layer by keeping an eye from hacker that could gain remote access to your Mac using the opened ports.
11. Established Connections - this tool displays your active connections. You can easy see if your Mac is connected to a third party unknown IP.

VI 5G Phone List: Even if it is delayed, Vodafone Idea will launch 5G service very soon. These Xiaomi smartphones will first be available with high-speed Internet.
VI 5G Phone List:
Jio and Airtel have already started 5G services across the country. But many are behind another telecom company Vodafone Idea in this race. Vodafone Idea’s 5G network has not yet been launched in any city in India. As a result, millions of customers of this telecom company are somewhat disappointed.
Vodafone-Idea (Vi) has announced a list of Xiaomi phones that will support 5G services. The telecommunications behemoth has revealed that it has tested the latest network on a number of Xiaomi and Redmi phones. To allow Vi users to enjoy the most recent network, a software update will be distributed to eligible devices.
“This collaboration will enable Xiaomi and Redmi smartphone users to enjoy enhanced data experiences on Vi 5G once the operator launches the services,” the telecom company said in a statement to ET. However, unlike Jio and Airtel, Vi has yet to launch 5G in any Indian city. Here’s what we know so far about the Vi 5G launch.
Despite lagging behind in the race, Vodafone Idea has made a big announcement today. Vodafone Idea has informed that this high-speed internet will be available on some smartphones. However, the company said that 5G will run on some smartphones of Xiaomi and Redmi in the initial phase.
In this context, the company said today, when Vodafone Idea 5G is launched, Xiaomi and Redmi smartphone users will be able to enjoy more advanced 5G services.
In which smartphone will VI 5G be available?
Recently, Vodafone had released a list of Idea phones. According to the company, this smartphone will be the first Vodafone Idea 5G to be launched.
- Xiaomi 13 Pro
- Redmi Note 12 Pro 5G
- Redmi 11 Prime 5G
- Redmi K50i
- Redmi Note 12 Pro+ 5G
- Redmi Note 12 5G
- Xiaomi 12 Pro
- Mi 11 Ultra
- Mi 11X Pro
- Xiaomi 11T Pro 5G
- Redmi Note 11T 5G
- Xiaomi 11 Lite NE 5G
- Redmi Note 11 Pro 5G
- Mi 11X
- Mi 10
- Mi 10T Pro
- Mi 10i
When will Vodafone Idea 5G be launched?
At present, the biggest question in the mind of the customers is when will the Vodafone Idea 5G network be launched? Where Jio and Bharti Airtel have already started 5G services in more than a hundred cities. However, we can see that there was no response from the company side. It is known that by 2024, Vodafone will be able to prepare the entire 5G infrastructure in the country.
VI has been running 5G tests on Xiaomi smartphones for a long time even though 5G services haven’t been launched. This can also be a big sign. Although it has not been officially announced, it is expected that Vodafone Idea will launch high-speed 5G services in India very soon.
On the other hand, Jio 5G has reached 406 cities across the country. Smartphone users are now enjoying 5G network instead of 4G. Mukesh Ambani’s company has also joined Airtel. Airtel has started offering 5G services in over 500 cities in India.
In a statement Know What Xiaomi India And VI Said:
In pursuit of a connected future and to realize the limitless potential of 5G in India, Xiaomi and Vi have joined forces to provide their customers with an unfiltered 5G network on their devices.
Vi has been collaborating with technology leaders, domain experts, start-ups, and device OEMs to develop 5G use cases for consumers and enterprises in India.
Xiaomi India remains committed to democratising technology for consumers across the country by offering best-in-class technology at an affordable price.

Epson Introduces the SD-10 Spectrophotometer Color Measuring Device
Underscoring its commitment to print quality, Epson America announced the Epson SD-10, the first Epson-built spectrophotometer. Designed to give SureColor wide-format customers a tool to accurately measure color, the SD-10 is an easy-to-use and full-featured color measuring device. The SD-10 is a compact, battery-powered device that can be used stand-alone via the built-in LCD display or wirelessly connected to a smartphone through the mobile app to make critical color decisions on-the-go. Allowing users to elevate their color with a simple color management tool, the SD-10 is ideal for print shops, designers and salespeople to capture, reproduce and confirm colors with confidence.
“Many existing color workflows are labor intensive and communicating color can be arbitrary and subjective,” said Eric Holm, professional imaging, Epson America, Inc. “Well received by both textile and signage users for its simplicity to measure and communicate accurate color, the Epson SD-10 allows an entire team to speak the same color language, from the salesperson to the designer to the print department.”
Measuring colors accurately, consistently, and quickly, the SD-10 is easy-to-use, easy to carry, and its embedded battery allows for measurements to be taken virtually anywhere, anytime. The SD-10 features market-leading technology, including industry-standard measurement modes (M0, M1e, M2) and Epson’s advanced micro-electromechanical system (MEMS) technology, used to construct devices with sub-micron precision. Accuracy on textured surfaces is achieved via a large 7.6 mm aperture and 360-degree LED illumination reduces shadows and irregularities to increase accuracy of color measurements. A built-in LCD display makes standalone operation possible, allowing for quick viewing of a measured color’s L*a*b* value. Additionally, the last two colors are always being compared and the delta-E value is displayed.
The Epson Spectrometer mobile app allows users to wirelessly connect to mobile devices where they can build custom color libraries, find similar PANTONE colors and compare measured colors. The app can be used to see where a color stands in comparison to your printer’s ICC profile. Additional features include:
- Wireless Bluetooth connectivity – Connect to a mobile device or computer using Bluetooth Low Energy technology
- Large aperture for textured surfaces – 7.6 mm aperture measures up to 1.5 times the area covered by similar products, allowing for greater accuracy
- Integration with Epson Edge Print software – Directly measure and replace colors within the print workflow; connect via Bluetooth or USB
- Build color libraries – Use the mobile app to create color palettes, find similar PANTONE colors and record measurements
The SD-10 spectrophotometer is now available through Epson Authorized Professional Imaging Resellers for $899 (MSRP).

Google and Android phone makers sued by Rockstar Consortium
A patent assertion entity – The Rockstar Consortium – which is owned by Apple, Microsoft, Blackberry, Sony and Ericsson has filed a complaint in the US for infringement of 7 patents related to smart phones by Google, Samsung, LG, HTC, Huawei, ZTE, and ASSUTek.
While this is one of many actions in this ongoing smart phone patent war, this appears to be the start of the biggest battle yet.
The patents were originally a Nortel patent which was auctioned off – Google was out bided in the auction by the Rockstar Consortium and no doubt regrets not making a higher bid.
Given the size of the players and the markets, the commercial outcome of this patent dispute will be measured in the Billions of dollars.

Two Way Messaging application is a unique application developed with the aim to service a wide range of short code / long code based applications. In it you can connect to various providers using the vendor independent SMPP (Short Message Peer to Peer) or HTTP (Hyper Text Transfer Protocol) protocol for sending and receiving messages. We can handle the following ranges of applications :
A lead keyword is the most basic keyword, here internally a static response is mapped against the given keyword, which is sent when that specific keyword is found at the beginning of the received message.
Poll keywords are used for running polls, where reply messages can be sent using the short message service. You can dynamically set the number of options, and the summary of poll results is dynamically updated on receipt of each message.
URL Based Keywords
URL Based keywords are the most advanced features of all, here we can feed in a custom URL on which a received message is to be forwarded, and response returned will be sent back to the mobile user who sent the message, thus providing a way to plug in our own business logic for such keywords.
Working of Two Way Messaging System
The SMS Pull and Push system is made up of three distinct modules.
Long Code Receiver
The Long Code Receiver is the starting point in the processing of messages. It does the job of pulling the messages from the SMSC to our end.
The message processor is the module responsible for processing of the messages, mapping messages to keywords etc. This is the module that connects the Reply Message Sender and Long Code Receiver.
Reply Message Sender
This module is just responsible for collecting the reply messages from the message processor module and submits these messages on the gateways specified. Capable of connecting with multiple SMPP based gateways, the gateway to use for sending is specified by the Processor module.

Telecom Batteries:Cell Towers & Data Centers
StorEn vanadium flow batteries are ideal for both telecom towers and data centers. Telecom tower batteries can be charged from the electrical grid or powered by renewable energy in off-grid locations, while batteries for data centers offer a backup electricity supply for added security. These batteries are essential for data integrity and continuity of communication and transmissions, but up to now, sustainable options have been lacking.
StorEn offers sustainable telecom batteries that are durable, reliable, and cost-effective. They can be used to collect energy from traditional electrical grids or renewable sources; this energy can be either stored until an outage occurs or it can be used to control utility costs by storing energy for use during peak consumption times, when rates are higher.
VANADIUM BATTERIES FOR TELECOM APPLICATIONS
Lithium batteries have allowed the telecom industry to begin the transition to renewable energy sources, but not without significant limits—they suffer fast decay and lose storage capacity over time. StorEn’s goal is to bring sustainability to the mainstream with vanadium flow batteries that overcome the shortfalls of lithium batteries.
Up until now, vanadium battery technology wasn’t ready for widespread use. Our engineers’ research and innovation has resulted in a vanadium flow battery that is 30 percent smaller than other batteries with similar storage capacities. StorEn technology is designed to easily scale up for widespread distribution.
Our patented Multigrids stack design means unmatched power density with a 50 percent cost reduction in the power side of the battery. StorEn batteries last over 15,000 cycles thanks to their Equilevels and Resafe technologies, and there’s no need for regular service inspections, which means reduced maintenance costs.
StorEn vanadium batteries offer the highest power density available with the smallest footprint and a unique modular architecture, making them well-suited for helping the telecom industry achieve sustainability.
THE VANADIUM BATTERY DIFFERENCE
When compared to lithium batteries, using vanadium flow batteries for telecom has a number of key advantages:
Vanadium flow batteries have no degradation of capacity over time; instead, they’re able to discharge fully at 100% throughout the battery’s entire lifespan.
The average vanadium flow battery lasts 25 years or longer.
StorEn batteries are designed to be low maintenance, making them a more cost-effective means of energy storage.
The vanadium electrolyte retains its end-of-life value and can be reused for a sustainable alternative to lithium telecom batteries.
Vanadium flow batteries have a non-flammable, water-based electrolyte that is non-explosive.
StorEn batteries are suitable for use indoors and outdoors, even in fluctuating temperatures.
Frequently Asked Questions about
Vanadium Flow Batteries for Telecommunications
How do vanadium flow batteries differ from lithium-ion batteries in telecom?
Compared to lithium-ion batteries, vanadium flow batteries reduce carbon emissions significantly. They also do not degrade over time discharging at 100% throughout the lifespan. Vanadium flow batteries last more than 15,000 cycles with minimal maintenance.
Are vanadium flow batteries environmentally friendly?
Vanadium flow batteries have a reduced environmental impact compared to lithium-ion batteries. With a lifespan of 25+ years, vanadium flow batteries are nearly 100% recyclable. The vanadium electrolyte can be reused, preventing the need for additional mining. Vanadium flow batteries also do not require the use of heavy metals such as nickel or cobalt.
Why use a vanadium flow battery for a cell tower or data center?
Vanadium flow batteries fill a void in sustainable battery options essential for continuity of communication and transmission, and data integrity preservation. Vanadium flow batteries for cell towers can be powered by both the electrical grid and renewable energy sources. Data centers can be made more secure by using a vanadium flow battery as a backup energy supply.
What are the risks of vanadium flow batteries in cell towers and data centers?
Vanadium flow batteries pose few risks because the electrolytes used are water-based, non-flammable, and non-explosive. They are safe for both indoor and outdoor use, even in areas of fluctuating temperatures.
What maintenance is required for vanadium flow batteries in cell towers?
Due to the patented multi grids stack design, there is no need for regular inspections of vanadium flow batteries, reducing costs by as much as 50%. Although 30% smaller than other batteries with similar storage capacities, vanadium flow batteries do not degrade over time and are designed to scale up for widespread distribution.

These comprehensive measures will reduce the temperature rise of the VMS, improve the reliability, and reduce the light decay of the LED.
With N+1 power supply backup. When the power supply fails, the backup power supply will seamlessly take over and notify the control center.
With bi-directional data transmission technology. When the data cable between any two cabinets is disconnected, the data can still remain ongoing transmission and avoid displaying interruption thanks to the bi-directional transmission technology.
Intelligent power distribution function: step-by-step power up, reducing the impact on the power supply lines.
Intelligent full monitoring capability: detect LED failures, monitor door status, power supply, fan, dust filter, internal temperature, ambient temperature, etc., and have a long-term preservation for the log records in the control center database.
Intelligent brightness adjustment function: based on the real-time monitoring of ambient brightness, proceed non-linear automatic dimming control (automatic mode).
Powerful software for traffic information management knows everything about the running status of the VMS. When the display content is updated, the LED is faulty, or the monitoring status is abnormal, it will feed back to the control center and send SMS to the operator, even if the operator is not at the control center, he can also know the running status of VMS in time.
Intelligent alarm function: Users can preset the temperature value for the alarm, brightness down, display off and power off. The VMS will carry out the corresponding actions according to the monitored temperature value.
VMS has surge protection, leakage protection and other safty measures
High temperature protection function: When the VMS temperature exceeds the set value, it will take the corresponding actions of alarm, brightness down, display off or power off, timely proceed the high temperature protection to ensure the safety for the VMS and prevent the occurrence of fire.
Traffic information management software, with login password protection function, unauthorized person can not operate the software and VMS; encrypted communication between the management software and VMS, illegal softwares are forbidden to control the VMS, to ensure the VMS operation of high security and accuracy.

Globally, there has been an explosion of wireless communication, especially of mobile phones. Wireless-phone subscription is growing faster than fixed-line subscription. The adoption of wireless communication technologies occurs for different reasons in different types of economies. For example in countries with poor fixed-line infrastructure, wireless becomes a technological substitute for fixed lines. Even in countries with adequate fixed-line infrastructure, the competitive rates for mobile phone services is making them an economic substitute for fixed lines.
For us living in the developed world, we use mobile phones mostly for connecting with people, for entertainment, getting access to news/information etc. And although we realize the big impact its made on our lives, we still cannot grasp the magnitude of the impact mobile phones have made, and continue to make, in the developing world. Mobile phones are a transformative technology that increases GDP and, quite simply, revolutionizes people’s lives.
Impact of Mobile Phones on Development:
Some statistics from Africa:
Mobile phones have had the biggest impact in Africa. Mobile phone subscriptions in Africa have risen from 16 million in 2000 to 376 million in 2008 – or one-third of sub-Saharan Africa’s population. In 1999 the Kenya-based service provider Safaricom projected that the mobile phone market in Kenya would reach three million subscribers by 2020. Safaricom currently has over thirteen million. And mobile phone use is booming despite high costs. The cheapest mobile phone in Kenya costs half the average monthly income. In 1999 less than 10% of rural Africans lived in areas with mobile phone coverage. Today, that number is more than 60%. Cost-benefit calculations are probably at the heart of mobile phone adoption.
Here are a few ways the power of these tiny wireless devices are changing lives in the developing world:
1) Increasing Market Efficiencies:
In the developing world, prior to the introduction of mobile phones, farmers, traders, and consumers had to travel long distances to markets, often over very poor roads, simply to obtain price (and other) information. Such travel imposed significant costs in time and money. Mobile phones, by contrast, reduce the cost of information and allowed traders to better respond to surpluses and shortages, thereby allocating grains more efficiently across markets and dampening price differences. Mobile phone coverage also increased traders’ profits and decreased the volatility of prices over the course of the year.
– In Kenya, the mobile service allows employers to post job listings and job seekers to get personalized text messages based on the kind of work they are looking for, improving its labor market efficiencies.
– In Bangladesh, a service called CellBazaar provides a mobile service equivalent of eBay or Craigslist.
– In the Indian coastal state of Kerala, mobile phones reduced price differences across fish markets by almost 60 percent between 1997 and 2001. When markets work efficiently, identical goods have the same price. And hence, the fishermen’s profits increased by 8 percent, and consumer prices declined by 4 percent.
2) Harnessing the Power of Remittances:
Remittances (the transfer of money by foreign workers to their home countries) are becoming an increasingly important source of finance for developing countries. From 2002 to 2007, the flow of remittances to developing countries more than doubled from $116 billion to $251 billion. Remittances are now more than twice as much as all foreign aid provided by major donors, which was $103.7 billion in 2007. Mobile carriers can play an important role in this market by making it quick, cheap and easy to transfer funds.
– In the Philippines, wireless providers like Smart Communications allow Filipinos working overseas to send money home in minutes with a text message for a fraction of the cost of money transfer operators. Overseas workers can also use text messages to directly pay specific expenses, such as school tuition, insurance premiums, hospital bills, and mortgages.
3) Building inclusive financial services:
Nearly three billion poor people in developing countries lack access to basic financial services such as savings, credit, insurance, and money transfers.
– In Kenya, a service called M-PESA facilitates a variety of financial transactions, from purchasing airtime to paying bills, though the majority of 13 million subscribers use it exclusively to transfer money. To transfer money to friends and relatives around the country, Kenyans could use Western Union or the post office, rely on an intermediary (for example, a bus driver), or ask a friend or relative. Wire transfers via Western Union or the post office were secure but often expensive and unavailable in remote rural areas. Transport services or sending via a friend or relative was more accessible but carried high risk of theft. By contrast, sending a thousand Kenyan Shillings (about $13) from Nairobi to the Western provinces via M-PESA costs 40 percent of the post office rate and 20 percent of the bus rate.
– In India, a firm has created a “branchless microbanking system” to allow people in remote areas to withdraw cash. A fingerprint reader identifies them and the sum is deducted from their accounts via a special handset. A small printer produces a receipt. The system already has more than 3m users in India, and in the state of Andhra Pradesh it directly disburses welfare payments and pensions.
4) Health Sector Benefits:
– Health practitioners have been at the forefront of using mobile phones as a development tool in Africa. Mobile phone services monitor measles outbreaks in Zambia; support diagnosis and treatment by health workers in Mozambique; and disseminate health-education messages in Benin, Malawi, and Uganda. In Malawi mobile phones not only remind HIV-positive patients to take their anti-retroviral drugs, but also allow community health workers to share information on their patients’ status, saving considerable time and money.
– Fighting Fake Drugs – 25% of drugs sold in the developing countries are fake. Last year, a mobile service was launched in Ghana and Nigeria to counter the fake-drug trade. People buying medicine scratch off a panel attached to the packaging. This reveals a code, which they can text to a computer system that looks it up in a database. Seconds later comes a reply saying whether the drug is genuine.
5) Impact on Literacy:
– Simple and affordable mobile phones are also being used as a means to promote adult literacy in Africa. In addition to a regular literacy curriculum, adults in the Nigerian village of Falenko learn where to find letters and numbers on a mobile phone and how to send and receive SMS messages. Early results suggest that students who use a mobile phone as a learning device make faster progress and achieve greater literacy than those relying solely on traditional classes.
– In Bangladesh, the BBC World Service launched a mobile service where for a few dollars a day, one can listen to hundreds on English lessons and quizzes – 3.1 million people have used it so far.
6) Helps Reduce Corruption:
– During the 2008 presidential elections in Ghana, a thousand locally trained PVT observers were able to transmit electoral results and violations via SMS to a central system, thereby giving almost instantaneous independent verification of the election results.
– In India, a farmer needing a land-ownership certificate can now get it directly using a mobile phone. This cuts off the middle-man – usually a corrupt government official who takes bribes.
– Following the 2007 election in Kenya, citizens reported on escalating violence via voice, SMS, and the Web.
– Crowdsourcing was also used to facilitate search-and-rescue operations following the earthquake in Haiti, allowing individuals to send messages on the locations of survivors, which were then mapped and broadcast to rescue teams.
Text messages are also being used to broadcast information from violence, to natural disasters, to election results.
9) Creating Innovative Ways to Communicate:
The developing nations have come up with innovative way to use the mobile phone technology – like the “missed call techniques” of communication that is used to compensate for the lack of calling minutes, or due to its simplicity and convenience in delivering a message.
10) Connecting the Excluded:
Mobile phones have helped in providing information to those who would have been excluded from the loop otherwise. Example – sending our market prices or other agricultural information for farmers in Uganda, or helping the Sri Lankan farmers time their harvest to maximise their income.
11) Citizen Media:
The term ‘citizen media’ refers to forms of content produced by private citizens who are otherwise not professional journalists. It is characterized by everyday citizens producing, collecting, and sharing information. Mobile phones can help facilitate this concept, and sometimes can also assist in winning freedom and democracy by allowing everyday citizens to participate in E-activism. This was clearly visible in the recent revolution in Egypt, where mobile phones played a crucial part in delivering messages and information. Since many web-based services couple with mobile phones for immediate posting of media, local citizens who have mobile phone access can become citizen journalists without a computer or access to an Internet connection.
The fact that most of the world’s population is entering the electronic communications age in a wireless mode has social and cultural consequences, the importance of which we are only beginning to perceive. The developing world have shown that poor people can become digital producers and even innovators. I think we haven’t even scratched the surface yet. With the introduction of 3G technology and access to high bandwidth data in the developing world in the near future, and with the prices of smart-phones and mobile-services continuing to fall, the possibilities are endless.
So, will mobile phones bring the developing world out of poverty? Years of development experience have taught us that there are no magic bullets. The promise of economic development in Africa cannot be fully realized in the absence of roads, schools, electricity, and finance. When IT is appropriately integrated into this larger framework, the transformation of the poor nations will finally be underway.

High voltage cable system optimization
We have been responsible for optimization of several high voltage and medium voltage cable systems in various industries. In order to provide the best solution for our Clients we have made specialized calculations, simulations and analysis.
Electrisim was appointed by Client to optimize underground high voltage cable (110 kV). The main task was to analyze all technical aspects of the cable and to provide technical specification (type, cross-sections, section length etc.) of the final cable system solution.
Description of the system
The work was part of construction of new wind farm where the high voltage underground cable (24 km trench length) connects the wind farm’s substation to the grid operator’s substation.
Electrisim carried several types of analyses to determine the optimal high voltage cable system. The scope of work included:
- Load flow analysis,
- Short circuit analysis,
- Calculation of continuous current rating based on IEC 60287 (for different scenarios, including cable installation in steel pipe). Determination of thermal current-carrying capacity of the conductor, sheathing, shielding and short-circuit forces,
- Calculation of the cyclic and emergency current rating of cables based on IEC 60853,
- Comparing the ampacity results with Finite Element Method,
- Power/energy losses calculation,
- CAPEX/OPEX analysis,
- Earthing/bonding specification,
- Determination of capacitance, charging current, earth-fault current, inductance, induced voltages and currents in ground wires, metal sheaths, and shielding,
- Selection of cable joint positions,
- Geotechnical tests on cable route for the verification of thermal resistivity,
- Trench backfilling specification, including selection of Fluidized Thermal Backfills, size of backfill envelope, trench size, configuration of cables,
- Calculation of pulling forces,
- Calculation of electric and magnetic fields around cable systems,
- Overvoltage, surge analysis (connecting surges, lightning etc.),
- Specification of cable temperature monitoring system and the effective use of results.

The coming broadband congestion
Web Informant #163, 8 August 1999
More and more of us are fortunate these days to have high-speed Internet access. I now enjoy Cablevisions cable modem at home and Wired Business/Covads DSL line in my office. Ive almost forgotten the sounds of a modem going through its dial-up routine, and my phone bills are no longer painful to pay. (Business users here in Bell Atlantic land have to pay for every minute of every ISDN call, local or not. That adds up when you connect to the Internet via ISDN, as I used to do from my office.)
But having a high-speed connection just moves the bottleneck for your access from your own immediate vicinity to some other place on the Internet. Overloaded servers and slow peering points will become more frequent as more and more of us obtain these connections. To show what we have in store for us, I turn to my friend Kim Maxwell ([email protected]).
Kim and I serve on Covads advisory board, just so you know. And Kim has written a recent book about various high-speed networking technologies, applications, and markets, from which this essay is excerpted with permission. You might argue that since he wrote this piece two years ago, the number of Internet users has grown way beyond his original estimates of 45 million. However, his math and analysis still remain the same. Take it away, Kim.
What will happen to the Internet when millions of users try to access it at high speeds using cable modems and DSL lines? What will happen if thirty percent of Internet traffic becomes continuous rather than intermittent data? I will show you with some simple arithmetic a scary situation that could mean we are in for some very congested times ahead. Indeed, we may have to shift a majority of high-speed and other broadband traffic to local servers located a few
miles from these heavy users, to avoid the Internet altogether!
Lets do the math together. Let us accept the claim that there are 45 million Internet users today, but only 10 percent of them use the network at any one time. Their average access rate is 28.8 kbps and their network usage -- the percentage of time data is actually on the line during a connection -- is 25 percent. In a crude sense, the network must process, in aggregate, 32.4 billion bits per second to handle this load.
Let us then suppose that, five years from now, the Internet has 200 million users, but 30 million of them have residential broadband at an average speed of 1.5 Mbps. If we make the same usage assumptions, the Internet must process 1280 billion bits per second, of which 1130 billion bits per second goes to broadband users. In ratio terms, 88 percent of network bandwidth is now supporting 15 percent of network users.
To keep up with this traffic, the Internet must more than double every year, with an annual user increase over the same period of only 34 percent. But this picture is unreasonably hopeful. Residential broadband users are always connected, removing one obstacle to more simultaneous users, particularly during peak loading hours, which seem to be weekday evenings.
This may be counteracted by proportionally longer waits between screens, reducing network usage per user. However, always-connected users will increase signaling load compared to traffic, and higher speeds will promote more frequent file transfers, an application with 100 percent usage.
Furthermore, within five years more and more Internet traffic will be video and streaming audio. To make matters worse, cable modems and at least 50 percent of ADSL modems installed at that time will actually run at 6 Mbps, suggesting that average broadband speeds may be closer to 3 Mbps. If we stir in some of these new assumptions, the aggregate network demand approaches 6.3 terabits per second!
Under these assumptions 98 percent of network capacity is used by 15 percent of its users and the network must quadruple annually, to grow to 175 times its present capacity in just five years. To get some idea of how big this really is, the same network capacity running under todays access conditions of dial-up modems and the 10/25 ratios of concentration would support 7.5 billion users, more than presently inhabit the globe. But there will be only 200 million users, and only 30 million broadband users.
Ultimately, users pay the bills. We can say almost without qualification that the network cannot grow that fast; even if it could, no one will want to pay for it. Network designers will scoff at the simple-mindedness of this analysis, and make claims for economies of scale, reduced hardware costs, faster routing with IPv6, faster routers, and free fiber bandwidth. But bandwidth is not free and even Moores Law will not keep up with 200 percent per year growth.
Thanks Kim. You can buy his John Wiley and Sons book, Residential Broadband from Amazon at the location below: http://www.amazon.com/exec/obidos/ASIN/0471251658/davidstromswebin/
Next week Ill talk more about my experiences with using both cable and DSL access technologies, and where I see both going in the coming years. And, Ill give you my thoughts on which technologies are best able to handle this coming congestion problem.

Beacon is the implementation of the tzip-10 proposal, which describes an interaction standard between a wallet and a dApp.
A dApp impelementing the beacon-sdk can build up a channel and send messages over a peer to peer communication layer to a wallet. This allows for a communication for example of a mobile wallet with a desktop application. The requests of the dApp are sent to the wallet, signed and returned to the application. The
beacon-sdk can also communicate to chrome extensions if compatible ones are installed.
beacon-sdk should allow developers to integrate this functionality with minimal coding, but still be customizable to support more complex flows.
For more information on how to integrate the
beacon-sdk in your DApp, read our Getting Started guide.
To get started, install the beacon-sdk from NPM:
npm install --save @airgap/beacon-sdk
# Upgrading from v1 to v2
Beacon SDK v2 introduces some some breaking changes from a developer perspective, most of the changes are internal, specifically in the communication protocol between dApps and Extensions/Wallets. All major Wallets that support Beacon (tzip-10) have been updated to support both v1 and v2 DApps.
We highly encourage developers to upgrade to v2. Besides stability improvements, the most notable new features are:
- Support for multiple browser extensions (eg. Thanos and Spire)
- Support for mobile, browser and desktop Wallets
- Mobile support via Deeplinking
- Secure and encrypted communication between DApp and Browser Extension
- WalletBeacon.io Source Code is the high-level explanation of beacon and is itself a DApp.
- Beacon Example Source Code is a small sample application built for the sole purpose of showcasing beacon integration.
A list of wallets with support for beacon is available here.

Configure Mikrotik RouterOS in Proxmox KVM virtual machine on OVH dedicated server
When I rented a dedicated server at SoYouStart (OVH‘s brand) in early 2015, I choose to install it with Proxmox VE 3.4. Proxmox VE enables you to use two types of virtualization at the same time: OpenVZ containers and KVM.
After my dedicated server setup has finished, an email was received with IP and root login information to access my Proxmox VE shell.
In this article I will use Server.IP as a reference to my Proxmox server IP address. OVH instructs to configure networking using a gateway which is first three octets of Server.IP and the last octet is .254. So my Proxmox was configured with a gateway of Server.254 (on interface vmbr0).
The goal was to configure server in the way the virtual machines running on this server will use private subnet and will be accessible via router (NAT), which runs in one of the KVM machines.
It is system administrator’s choice of router software, so one could go for the great piece of open source software pfSense, but this time I choose Mikrotik‘s RouterOS (for x86) since I am using it with Mikrotik routers for a few years now and I am very familiar with it.
My private subnet will be 10.1.100.0/24, so I have reserved 10.1.100.1 for the KVM router and 10.1.100.254 for the vmbr2 on the server.
Edit /etc/networking/interfaces and add your private subnet virtual bridge (vmbr2).
$ vi /etc/newtork/interfaces auto vmbr2 iface vmbr2 inet static address 10.1.100.254 netmask 255.255.255.0 gateway 10.1.100.1 bridge_ports none bridge_stp off bridge_fd 0
Be sure to create some type of fallback in case something goes wrong (like you are used to do with firewall, if you configure it remotely). Now restart networking or your server.
Go back to your OVH/SoYouStart control panel and order some IPs for this server. Order at least a block of 8 IPs (/29) or a block of 16 IPs (/28). You will receive an email with your IP block and explanation how to use it.
I got the block of 151.X.Y.176/28 and the most crucial information is this part:
Network IP : 151.X.Y.176 IP for router n°1 : 151.X.Y.188 IP for router n°1 : 151.X.Y.189 Gateway IP : 151.X.Y.190 (not usable) Broadcast IP: : 151.X.Y.191
This means my KVM router will have WAN address 151.X.Y.189 (Router.IP) and I can use all other IPs (151.X.Y.177 – 151.X.Y.188) to NAT to my private subnet with virtual machines.
Again, go back to your SoYouStart control panel, select your server and Add a virtual MAC to the Router.IP (MAC type OVH).
Add this existing virtual MAC address to all your IPs that will be routed via your KVM router.
Now it’s time to download RouterOS (CD ISO image for x86) and upload it to your Proxmox VE server. Create a new virtual machine (router KVM) with 1 CPU, max. 256MB RAM, some hard disk and a network device in vmbr0 (with your OVH virtual MAC address).
In the Hardware tab add another network device (in vmbr2), mount RouterOS ISO image and install it.
Log in to your RouterOS KVM router with admin/<no password> and write down the software ID which you will need to buy the RouterOS license (you have 24h to buy and enter a valid license). I bought a license at mikrotik-routeros.net. It was great price, fast and no problems.
In RouterOS terminal issue a command to print interfaces and find out, how is named the one which is in vmbr0 and has your OVH virtual MAC address.
This is your WAN interface and the other is your LAN (private) interface.
[admin@Mikrotik] interface print value-list
In my case the WAN interface was named ether1 and my LAN interface was named ether2.
Configure your router (replace 151.X.Y.189 with your Router.IP):
[admin@Mikrotik] /ip address add interface=ether1 address=151.X.Y.189/32 broadcast=151.X.Y.189 /ip address add interface=ether1 address=151.X.Y.189/32 network=Server.254 /ip route add dst-address=0.0.0.0/0 gateway=Server.254 /ip firewall nat add chain=srcnat out-interface=ether1 action=masquerade /ip address add interface=ether2 address=10.1.100.1/24
That’s it. The basic configuration of your KVM router is up and running.
Now you can add virtual machines/containers with their network interface in vmbr2.
Use your private subnet IPs (10.1.100.0/24) and your private router address (10.1.100.1) as their gateway. Configure dst-nat/src-nat on your router and your services are set.
Do not forget to secure your server and configure firewall!
If you have any additional questions, do not hasitate to ask or just leave a comment.

Hams have always managed to adapt inexpensive commercial gear for amateur radio use. In decades past we adapted military surplus and used commercial radios. Now in the digital age we can use inexpensive WiFi gear for amateur use. A complete 13cm (2.4ghz) ham station can be purchased for $100 or less (see WiFi Devices below). The station can operate under FCC part 97 on a portion of the 13cm ham band that isn’t used by unlicensed 802.11 WiFi devices. Or the station can be operated under FCC part 15 on 802.11 frequencies and inter-operate with non-ham wireless networks in your neighbourhood.
WiFi RF Spectrum:
Most consumer 802.11 devices, commonly called WiFi, operate in the 2.4ghz (13cm) band. Some WiFI manufacturers make 5.8ghz (5cm) and 900mhz (33cm) equipment. Hams share the 2.4ghz and 900mhz bands with ISM (Industrial Scientific & Medical) devices which includes WiFi devices.:
Unlicensed ISM (FCC part 15): 2400 – 2495 Mhz
Amateur (part 97) 13cm band: 2390 – 2450 Mhz
Hams are the PRIMARY users in the US on 2390mhz-2417mhz and secondary users elsewhere. The ISM band is divided into 11 overlapping 802.11 channels, each 5mhz wide. Channel 1 is centered at 2412mhz. Channel 11 is centered at 2484mhz. An 802.11 RF signal is 20mhz wide, using parts of 5 adjacent channels. So, there are only three non-overlapping channels, 1, 6, and 11. Hams may use WiFi gear under FCC part 97 if they stay within 802.11 channels 1 through 6 so the RF signals will be within the 13cm ham band. Also, some WiFi devices can be changed to use a 5mhz wide signal, at 1/4 the data rates, on frequencies outside the 802.11 channels. For example, Ubiquity (http://www.ubnt.com) outdoor WiFi devices can operate at 2397mhz with a 5mhz wide signal, as suggested by the HSMM 13cm band plan. This is within the PRIMARY portion of the 13cm ham band but not in the ISM band. This should reduce unwanted interference from part 15 devices.
Earlier 802.11b equipment used spread spectrum techniques. Later 802.11g equipment uses OFDM (orthogonal frequency division multiplexing). Most modern WiFi devices will support both 802.11b and 802.11g, automatically adapting to the method in use. WiFi devices can automatically choose different modulation techniques, depending upon signal strength, to achieve higher data rates when RF signals are strong enough. 802.11g devices can choose among BPSK, QPSK, 16-QAM and 64-QAM modulation types, used to modulate each sub-carrier of the OFDM signal. This gives data-rates betwen 6 and 54 mbps (megabits per second). 802.11b modulation gives data rates between 1 and 11mbps.
RF Power levels:
Transmitter power of home WiFi gear is typically around 50mwatt to 100mwatt. FCC part 15 limits transmitter power to 1 watt. There are some inexpensive WiFi devices with 0.4 watt to 1 watt transmitters. Part 15 limits the ERP (Effective Radiated Power) by requiring that the transmitter power be reduced by 1db for each 3db of antenna gain in excess of 6db. So, for example, a WiFi device using an 18 db gain antenna must transmit using no more than 1 watt minus 4db (i.e. 0.397watts). The 4db is calculated from (18-6)/3. Part 97 users have no such antenna restrictions, and transmitter power is limited to the usual 1500watts PEP (for 802.11g which is not spread spectrum). Very high power is a moot point for most hams, since 2.4ghz power amps are expensive. A 10 watt 2.4ghz two-way amp, which includes a receive pre-amp, costs over $800 at this time. However, using a 2.5 foot reflector or yagi antenna with 24db gain, costing about $60, and a 0.8 watt transceiver costing less than $100, hams can achieve an ERP of 200 watts. Such an antenna will have a “beam width” of about 8 degrees, which will reduce interference from other WiFi devices.
2.4ghz propagation distance:
The main disadvantage for hams use of Wifi, as with all microwave communications, is that range is effectively limited to line-of-sight distances. I observe that trees, houses, etc., reduce a 2.4ghz signal by 20db or more. Antennas mounted atop typical 50′ ham towers in my experience provide about 2 to 4 mile range. To achieve 2.4ghz line-of-sight communications over a distance of 24 miles, comparable to the range of a typical ham VHF/UHF repeater, assuming level ground with 50′ tall trees and buildings, you’d need both antennas to be 120′ above ground. This is beyond the ability of most individual hams, although ham clubs can often put antennas above 200′ on existing towers or tall buildings. A 2.4ghz repeater with antenna at 300′ would be needed to provide a 24 mile coverage radius to users with antennas only just high enough for the signal to be clear of nearby trees, buildings, etc. The required antenna height is determined by adding the height of obstructions to the height needed to achieve the desired “radio horizon” distance. Visit http://www.qsl.net/w4sat/horizon.htm and enter the two antenna heights. This calculates radio horizon distance. You must add to this antenna height the height needed to overcome any obstructions in the signal path. When considering the height of obstructions, it is common to add an additional 10′ to 15′ to keep the entire Fresnel zone free of obstructions.
You must also transmit sufficiently powerful signal to overcome the “path-loss”. The 2.4ghz free space path-loss is about 100db+20log(kilometers). For a 24 mile (40km) path, the path loss is 132db. A 24db gain receiving antenna reduces it to 108db. With a 0.8 watt transmitter and 24db gain antenna, the ERP of the transmitted signal is +50dbm (200 watts). This signal will be 35db above a typical -93dbm noise floor at the receiver. With the WiFi devices I’ve used, any signal stronger than about 20db above the noise provides a reliable connection.
An on-line calculator, provided by ve2dbe and towercoverage.com, will predict the received signal strength between any two points you select on a map. It takes into consideration the frequency, transmitter power, receiver sensitivity, antenna gain, antenna height. It uses terrain elevation map data, vegetation (trees) data, and urban (building) map data. I’ve found this calculator to predict fairly accurately the actual signal strengths I’ve observed. Received signal strength in excess of about -75dbm usually is sufficient for the WiFi equipment I’ve used. You must sign-up for a free account to use this online calculator
Ham WiFi Uses:
Because of the need for line-of-sight, one practical use for WiFi may be the wireless linking of existing analog VHF/UHF ham repeaters. Most ham repeater antennas are at fairly high locations, so maintaining line-of-sight over many miles should be achievable. Assuming level ground and 50 ft obstructions (trees, buildings, etc), two repeaters with antennas 200′ AGL have line-of-sight for 34 miles. For 150′ antennas, line-of-sight is 28 miles. The repeater audio would be changed to digital VOIP and sent between repeaters. There is free software (Asterisk, Ekiga, etc) that could be used for this. There would be plenty of bandwidth left over to use for other purposes, such as APRS, etc.
Digital Voice and Digital Amateur TV:
Digital Voice and ATV are easily accomplished with WiFi. A WiFi link provides plenty of bandwidth for digital voice communications without the need for voice data reduction schemes, as are required on D-STAR, P-25 and other narrow-band schemes. Free VOIP software such as Ekiga or older versions of NetMeeting can be used. As you speak into a microphone attached to your computer’s sound card, the software sends it as VOIP data to the receiver’s computer, where it is converted back to audio using that computer’s sound card. The same software can also be used for video links as well as audio. The only difference is that video from a camera is digitized and sent rather than audio from a microphone.
Make use of AMPR IP addresses (44.xx.xx.xx):
In the late 1970s, at a time when IP addresses were not in short supply as they are now, hams were granted a large block of about 16 million IP addresses (44.xx.xx.xx) worldwide, for use in connecting ham radio equipment to and through the internet. This IP block is known as AMPRNet (Amataur Radio Packet Network). See http://www.ampr.org for more information. Sub-blocks are given to each state and major cities. For example, Missouri has block 44.46.xx.xx. States have one or more hams who coordinate use of the IPs. WiFi gear used by hams could make good use of these IP addresses, before someone tries to take them away from hams. IP addresses are now valuable. Microsoft recently paid $7.5 million for a little over half a million IP addresses.
WiFi devices typically don’t have control knobs like a radio. Instead they contain a web-site which is used to control the device from your computer using your favorite web-browser (Internet Explorer, Firefox, Chrome, etc). You normally plug your WiFi device directly into your computer using an ethernet cable, and configure it using your favorite web-browser.
IP addresses are the “call signs” of computer networks. Hams call each other on-air using call signs. Similary, when computers want to talk to each other over a network, they call each other using “IP Addresses”. Each device on a computer network is assigned an IP address, just as each ham operator is assigned a call-sign. Hams usually give the “destination” call-sign and their own call sign at the beginning of each transmission. Each computer MUST give the “desgination” IP address and it’s own IP address (the “source” address) at the beginning of each transmission. Each computer transmission is known as a “packet”. Therefore, to talk to the WiFi device, your computer must know the “IP Address” of the device. For the WiFi device to reply to your computer, it needs to know the IP address of your computer. Unlike ham call-signs, which can only be assigned by the FCC, any computer can assign itself an IP address, provided that IP address isn’t already used by some other computer in the network. Your WiFi device user manual will tell you the factory default IP address of the device. It is typically 192.168.1.1 or 192.168.1.20 or 192.168.1.50. You normally plug your WiFi device directly into your computer using an ethernet cable, and point your web-browser at http://192.168.1.1 (or xxx.20 or xxx.50).
Normally each computer on a network doesn’t choose it’s own IP, but is assigned a unique IP address by one computer on the network acting as a “DHCP server”. Just as the FCC assigns each ham a different call sign, the DHCP server assigns a different IP address to each new computer when it is turned on and joins the network. In your local home network, the router that was provied by your ISP probably acts as the DHCP server. However, after you’ve plugged your computer directly into the WiFI device, your computer is no longer connected to the DHCP server, so it cannot automatically obtain an IP address as it usually does. So you probably need to use the “network connections” icon on your computer’s control panel to manually specify an IP address for your computer. Choose an IP address such as 192.168.1.XX, but don’t choose the same IP as your WiFi device. You’ll also need to specify a network “mask”. Specify 255.255.255.0. If required, specify a “gateway” IP address of 192.168.1.1. After you’ve done this, you should be able to enter “http://192.168.1.1″ or “http://192.168.1.20″ into your web-browser and see the login-page of the WiFi device’s website. Your WiFi user manual will tell you the login name and password to use.
Router vs. Bridge mode:
Each WiFi device can typically be configured either in “router” or “bridge” mode. Your internet service provider probably provided you with a router that your computer connects to. Each single local computer network needs only one router (although more routers are allowed). So you’ll probably want to configure your WiFi device in “bridge” mode, which is usually the default setting. Router mode and computer network routing is beyond the scope of this webpage. Hams most often use WiFi routers in a wireless MESH network (see http://hsmm-mesh.org for example).
In bridge mode, your WiFi device acts much like a ham “repeater”. The “bridge” device will re-transmit any transmission that it “hears”. The bridge records each incoming transmission and then immediately re-transmits it. Unlike your local ham repeater which has one transmiter and one receiver, the bridge has two transceivers, one attached to the ethernet cable and one attached to the antenna. Each incoming transmission on either transceiver is re-transmitted on the OTHER transceiver. So data heard on the wireless receiver are re-transmitted over the ethernet cable, and data heard on the ethernet cable are re-sent over the wireless transmitter. So a pair of wireless bridges, each of which is wired to a computer, act just like a long ethernet cable connected between the two computers.
Access Point vs. Station mode
In a ham VHF or UHF repeater, all users transmit to the repeater and receive the repeater. They don’t communicate “direct” to each other. Similarly, in a WiFi network, there is one WiFi device configured as an “Access point” which acts like the ham repeater. Every other WiFi device is configured as a “station”. Each station communicates only with the Access point.
Just as hams can communicate “direct” with each other, without using a repeater, so can WiFi stations communicate with each other. This is called “peer-to-peer” communications, or sometimes “ad-hoc” networking.
WDS (Wireless Distribution System) mode:
Hams sometimes link nearby repeaters to each other using RF links. Each repeater “forwards” incoming transmissions on to the other repeaters. This provides for a wider coverage area, allowing anyone within range of any repeater to talk to anyone else within range of any repeater. Similarly, a non-standard 802.11 extension called WDS can be used to link several nearby WiFi access points together. One of these “WDS Access Points” is usually connected to the internet. Each other WDS Access Point forwards data between wireless “stations” connected to it and the other WDS Access Points. In this manner, data from any “station” Wifi device uses multiple wireless “hops” between WDS Access Points to reach the internet connection. Each “hop” takes about the same amount of time to send one packet of data to the next hop. So, with 2 hops the effective data-rate is reduced to 1/2, with 3 hops the data-rate is reduced to 1/3, etc. Finally, since WDS is not part of the 802.11 standard, different manufacturers might implement it differently. So there’s no guarantee that WDS will work among devices from different manufacturers.
WIFi MESH networks:
One problem with using WDS is that each time you add a new WDS Access Point you must manually specify to it which other nearby WDS nodes it should forward data to. You must also reconfigure the nearby WDS nodes, adding the newly added WDS node to their list. This slows down rapid deployment of a WDS network, especially when the network must change often to accomodate changing emergency conditions. This manual configuration problem can be eliminated using the HSMM-MESH firmware from http://hsmm-mesh.org. The firmware is uploaded into Linksys WRT54G WiFi devices. When several such devices are deployed as a MESH network, the devices will automatically discover each other, and automatically configure their routing so that data can go between any two computers attached to the network, or between any computer and the internet connection. As MESH network nodes are added and removed, the firmware automatically discovers the changes and reconfigures itself.
The OpenWRT firmware is also popular among mesh network enthusiasts. OpenWRT can be loaded onto many different WiFI devices, including new models with higher powered transmitters designed to be mounted outdoors next to an antenna. OpenWRT is basically a small distribution of the Linux operating system designed to run on the CPU within WiFi devices. It provides many ways to customize your WiFi devices using various application firmware (smart phone users call them “apps”). Among these are the popular B.A.T.M.A.N., OLSR and R.O.B.IN firmware, available for free at http://opensourcemesh.org. These firmware “apps” implement mesh network routing protocols.
In metropolitan areas, there may be two or more ham repeaters on the same frequency within range of a ham with a good antenna. So, ham repeaters use CTCSS to allow each ham to select which repeater he wants to communicate with. To use any particular repeater, each ham configure his radio to use the CTCSS of that repeater. Similarly, each WiFI Access Point chooses an SSID. The SSID can be any word of 32 letters or less. Each WiFi station that wants to talk to the Access Point must use the same SSID as the Access Point.
802.11 WiFi devices may encrypt their transmissions for security reasons. There are two encryption methods to choose from: WEP and WPA (now WPA2). When using encryption, the WiFi Access Point is configured to use a secret word, called a “key”. Every station wishing to communicate with that access point must be configured to use the same key. Hams using WiFi devices under part 97 must disable encryption which is expressly forbidden by the FCC.
Deploying a WiFi device:
Hams usually want to mount a WiFi antenna outside, or at least near a window, so the $20 to $30 USB WiFi devices are not a good idea unless your computer is outside or near a window. There are many WiFi devices designed for home use, often called “Access Points”, in the $30 to $50 range, that have an ethernet connection to your computer instead of USB. These typically have 50mw to 100mw transmitters, and attached antennas about 4 inches long with a gain of about 5db. Due to the excessive losses in long runs of coax cable, hams usually mount the entire WiFi transceiver, including antenna, outside on a roof or tower. In years past I’ve enclosed indoor WiFi devices in PVC weatherproof boxes from Home Depot ($12 to $35 depending upon size). You then run an ethernet cable (Cat-5 network cable) from the WiFi device to your computer. Now days there companies like Ubiquiti and EnGenius make outdoor Wifi transceivers with 500mw transmitters, integrated antennas and “power-over-ethernet” (POE) for $65 to $100. POE eliminates the need to have electric power atop your tower or roof. At these inexpensive prices, there’s no longer any economic reason to build your own weatherproof enclosure or antenna. For example, the Ubiquiti AirGridM2 with 16db reflector antenna and POE is outdoor mountable and costs $65 new.
Some WiFi Devices I’ve Used
The WRT54G has been around for almost a decade. It costs about $35 on ebay these days. It has about 100mw transmitter and a detachable antenna with a reverse polarity TNC coax connector (RP-TNC). Over the years Linksys built 8 versions of WRT54G. The first 4 versions are still popular with hams and others wishing to create a wireless MESH network. The http://hsmm-mesh.org group provides free firmware which can be uploaded into a WRT54G device (versions 1-4 only). Such devices can automatically detect each other if within range, and automatically route data through the network.
See http://ubnt.com for Ubiquiti’s line of WiFi devices. The NanoStation LoCo (100mw) costs about $48. The NanoStation2 (400mw transmitter) costs about $80. Each have a built-in 10db directional antenna. It has a weatherproof case suitable for outdoor mounting. It has power-over-ethernet, so you don’t need electric power at your antenna. Like other Ubiquiti outdoor products, the NanoStation2 uses the Atheros wireless chipset. These chips are capable of operation on additional frequencies in the 13cm ham band that are not allowed for unlicensed WiFi use in the US. Configure the Ubiquiti firmware’s country to “Conformance Test” instead of “USA” in order to gain access to these additional frequencies. Be careful to insure you then select frequencies within the ham band. Also like other Ubiquiti products, you can configure the device to use a 5mhz wide signal (non standard) instead of a 20mhz wide signal. This should provide increased range due to 4x power spectral density, at the expense of reducing the data rate to 1/4. So data rates are between 1.5mbps and 13mbps , instead of 6mbps and 54mbps. Even 1.5mbps is plenty of bandwidth for most ham uses.
The Bullet2 (100mw transmitter) costs about $40 new, and the Bullet2-HP (800mw transmitter) costs about $80 new. The outdoor weatherproof unit is shaped like a cylinder (a bullet) with the N-series male coax connector at one end. This makes it is easy to mount directly to a high-gain antenna which often come with an N-series female coax connector. It uses power-over-ethernet, but you must purchase the power supply separately (about $14). Several 24db gain parabolic reflector antennas, about 24″x39″ in size, are available for about $60 plus shipping. So a complete 13cm ham station with 200 watts (53dbm) EIRP costs only about $154, using your existing tower or antenna mast.
The AirGridM2 (500mw transmitter) costs $65 new and comes with integrated 16db reflector antenna, POE, and antenna mast mounting clamp. Just clamp it to a pole or tower and run cat-5 cable to your ham shack’s computer and you’re on-the-air on 13cm band. A version with a 17″x24″ 20db antenna is available for about $95, providing 50 watts (47dbm) EIRP. That provides a complete 13cm station using your existing tower or antenna mast.
EDUP EP-AB003 8-Watt 2-way power amplifier
The price of 2.4ghz power amplifiers has dropped in recent months from about $200 for a 1-watt amplifier to $59 for an 8-Watt amplifier. I recently tested the EDUP EP-AB003 8-Watt amp (from China) by attaching it to a Linksys WRT54G wireless router. This amount of power is only legal when used with a ham license, on the first 5 WiFi channels which overlap the 13cm ham band. I used a Ubiquiti Bullet, mounted atop a tower about 50 yards away, to measure the Linksys signal strength with and without the amplifier. The Linksys stock antenna (5db) was used without the amp, and the antenna that came with the amp (about 6db) was used with the amp. This antenna is about 1-inch longer than the Linksys antenna, so that may account for 1 or 2db of the gain I observer. Here’s the results of my test:
Linksys without amplifier: -58dbm to -70dbm average -64dbm
Linksys with amplifier: -42dbm to -56dbm average -49dbm (15db increase)
The EP-AB003 specs say the transmit gain should be 17db. My measured 15db is within the error tolerance of my measurements. The amplifier may only be responsible for 13db to 14db of this gain, due to slightly longer antenna. The EP-AB003 input power limits are 3mw to 100mw. I believe the Linksys with stock firmware is about 50-100mw. Assuming 80mw Linksys output and 14db amplifier gain, the amplifier output power was 2.0 watts. The EP-AB003 specs say the receiver gain is 11db with a 3db typical noise figure. The Linksys I used had no way to measure anything about the received signal strength from the Ubiquiti bullet.

Editing WhatsApp messages after they’ve been sent… in testing
Yesterday, Monday, WABetaInfo reported that the WhatsApp instant messaging service continues to develop its new feature that allows users to edit sent messages. We tested one of the most requested features – editing messages – in version 22.23. Apple.
At the time, WABetaInfo stated that the feature would allow users to edit messages within 15 minutes of posting them. Thus, this feature will be useful for correcting any error in messages or adding new information to them before the other party sees them.
And while WhatsApp now allows users to delete any message sent before the other party sees it, the feature is intended for users who don’t want to delete messages, but rather modify their content before they are seen.

Azure Operator Nexus is the next-generation hybrid cloud platform created for communications service providers (CSP). Azure Operator Nexus deploys Network Functions (NFs) across various network settings, such as the cloud and the edge. These NFs can carry out a wide array of tasks, ranging from classic ones like layer-4 load balancers, firewalls, NATs, and 5G user-plane functions (UPF), to more advanced functions like deep packet inspection and radio access networking and analytics. Given the large volume of traffic and concurrent flows that NFs manage, their performance and scalability are vital to maintaining smooth network operations.
Until recently, network operators were presented with two distinct options when it comes to implementing these critical NFs. One utilize standalone hardware middlebox appliances, and two use network function virtualization (NFV) to implement them on a cluster of commodity CPU servers.
The decision between these options hinges on a myriad of factors—including each option’s performance, memory capacity, cost, and energy efficiency—which must all be weighed against their specific workloads and operating conditions such as traffic rate, and the number of concurrent flows that NF instances must be able to handle.
Our analysis shows that the CPU server-based approach typically outshines proprietary middleboxes in terms of cost efficiency, scalability, and flexibility. This is an effective strategy to use when traffic volume is relatively light, as it can comfortably handle loads that are less than hundreds of Gbps. However, as traffic volume swells, the strategy begins to falter, and more CPU cores are required to be dedicated solely to network functions.
In-network computing: A new paradigm
At Microsoft, we have been working on an innovative approach, which has piqued the interest of both industry personnel and the academic world—namely, deploying NFs on programmable switches and network interface cards (NIC). This shift has been made possible by significant advancements in high-performance programmable network devices, as well as the evolution of data plane programming languages such as P4 and NPL. For example, programmable switching Application-Specific Integrated Circuits (ASIC) offer a degree of data plane programmability while still ensuring robust packet processing rates—up to tens of Tbps, or a few billion packets per second. Similarly, programmable Network Interface Cards (NIC), or “smart NICs,” equipped with Network Processing Units (NPU) or Field Programmable Gate Arrays (FPGA), present a similar opportunity. Essentially, these advancements turn the data planes of these devices into programmable platforms.
This technological progress has ushered in a new computing paradigm called in-network computing. This allows us to run a range of functionalities that were previously the work of CPU servers or proprietary hardware devices, directly on network data plane devices. This includes not only NFs but also components from other distributed systems. With in-network computing, network engineers can implement various NFs on programmable switches or NICs, enabling the handling of large volumes of traffic (e.g., > 10 Tbps) in a cost-efficient manner (e.g., one programmable switch versus tens of servers), without needing to dedicate CPU cores specifically to network functions.
Current limitations on in-network computing
Despite the attractive potential of in-network computing, its full realization in practical deployments in the cloud and at the edge remains elusive. The key challenge here has been effectively handling the demanding workloads from stateful applications on a programmable data plane device. The current approach, while adequate for running a single program with fixed, small-sized workloads, significantly restricts the broader potential of in-network computing.
A considerable gap exists between the evolving needs of network operators and application developers and the current, somewhat limited, view of in-network computing, primarily due to a lack of resource elasticity. As the number of potential concurrent in-network applications grows and the volume of traffic that requires processing swells, the model is strained. At present, a single program can operate on a single device under stringent resource constraints, like tens of MB of SRAM on a programmable switch. Expanding these constraints typically necessitates significant hardware modifications, meaning when an application’s workload demands surpass the constrained resource capacity of a single device, the application fails to operate. In turn, this limitation hampers the wider adoption and optimization of in-network computing.
Bringing resource elasticity to in-network computing
In response to the fundamental challenge of resource constraints with in-network computing, we’ve embarked on a journey to enable resource elasticity. Our primary focus lies on in-switch applications—those running on programmable switches—which currently grapple with the strictest resource and capability limitations among today’s programmable data plane devices. Instead of proposing hardware-intensive solutions like enhancing switch ASICs or creating hyper-optimized applications, we’re exploring a more pragmatic alternative: an on-rack resource augmentation architecture.
In this model, we envision a deployment that integrates a programmable switch with other data-plane devices, such as smart NICs and software switches running on CPU servers, all connected on the same rack. The external devices offer an affordable and incremental path to scale the effective capacity of a programmable network in order to meet future workload demands. This approach offers an intriguing and feasible solution to the current limitations of in-network computing.
In 2020, we presented a novel system architecture, called the Table Extension Architecture (TEA), at the ACM SIGCOMM conference.1 TEA innovatively provides elastic memory through a high-performance virtual memory abstraction. This allows top-of-rack (ToR) programmable switches to handle NFs with a large state in tables, such as one million per-flow table entries. These can demand several hundreds of megabytes of memory space, an amount typically unavailable on switches. The ingenious innovation behind TEA lies in its ability to allow switches to access unused DRAM on CPU servers within the same rack in a cost-efficient and scalable way. This is achieved through the clever use of Remote Direct Memory Access (RDMA) technology, offering only high-level APIs to application developers while concealing complexities.
Our evaluations with various NFs demonstrate that TEA can deliver low and predictable latency together with scalable throughput for table lookups, all without ever involving the servers’ CPUs. This innovative architecture has drawn considerable attention from members of both academia and industry and has found its application in various use cases that include network telemetry and 5G user-plane functions.
In April, we introduced ExoPlane at the USENIX Symposium on Networked Systems Design and Implementation (NSDI).2 ExoPlane is an operating system specifically designed for on-rack switch resource augmentation to support multiple concurrent applications.
The design of ExoPlane incorporates a practical runtime operating model and state abstraction to tackle the challenge of effectively managing application states across multiple devices with minimal performance and resource overheads. The operating system consists of two main components: the planner, and the runtime environment. The planner accepts multiple programs, written for a switch with minimal or no modifications, and optimally allocates resources to each application based on inputs from network operators and developers. The ExoPlane runtime environment then executes workloads across the switch and external devices, efficiently managing state, balancing loads across devices, and handling device failures. Our evaluation highlights that ExoPlane provides low latency, scalable throughput, and fast failover while maintaining a minimal resource footprint and requiring few or no modifications to applications.
Looking ahead: The future of in-network computing
As we continue to explore the frontiers of in-network computing, we see a future rife with possibilities, exciting research directions, and new deployments in production environments. Our present efforts with TEA and ExoPlane have shown us what’s possible with on-rack resource augmentation and elastic in-network computing. We believe that they can be a practical basis for enabling in-network computing for future applications, telecommunication workloads, and emerging data plane hardware. As always, the ever-evolving landscape of networked systems will continue to present new challenges and opportunities. At Microsoft we are aggressively investigating, inventing, and lighting up such technology advancements through infrastructure enhancements. In-network computing frees up CPU cores resulting in reduced cost, increased scale and enhance functionality that Operators can benefit from through our innovative products such as Azure Operator Nexus.

The IPv6 address space differs from the IPv4 address space in several ways. There are new address types and the fields of the addresses are assigned different meanings. This paper describes the IPv6 address space as laid out in several Internet RFCs and Internet Engineering Task Force Internet Drafts and also presents some methods designed for address assignment and management.
When IPv6 was in its early stages, one of the main topics of the discussion was how long the IPv6 address should be. The IPv4 address is 32-bit, with a theoretical maximum of over four billion addresses. The hierarchy of the IPv4 address, i.e. network, subnet and host, reduces the actual amount of addresses available. In [HRATIO] Huitema presents what he calls the H ratio for address assignment efficiency. It is calculated with the formula
log (number of objects) H = ----------------------- available bits
In the following examples Huitema uses base 10 logarithms, as that is the more natural way of thinking of large numbers. Thus the H ratio ranges from 0 to 0.30102 (log10 of 2).
To try to figure out how large the IPv6 address space should be, Huitema uses some examples of similar numbering schemes. The focus is on how large the systems grew before they had to be extended to allow new nodes to be added to the system.
With these examples in mind Huitema constructs the following table for the different possible IPv6 address sizes. The numbers express the maximum number of IPv6 addresses.
|bits||Pessimistic (0.14)||Optimistic (0.26)|
An estimate for the number of Internet hosts in the future is 1015. The 64 bit alternative lies below or above the estimate depending on your point of view. The 128 bit address, however, is more than enough. As a matter of fact, if you assign 80 bits of the address to the "network" part and leave 48 bits (the IEEE hardware link layer address length) for stateless address autoconfiguration, you still end up with a reasonable worst case of almost 1012.
The IPv6 addresses are 128 bits long.
An IPv6 address consists of 128 bits, and is usually written as a text string of eight 16-bit hexadecimal numbers. The address itself refers to an interface, rather than a node as in IPv4, and one interface may be assigned several addresses.
Addresses will usually have long strings of zero bits, so a textual
format for compressing zeroes in the address has been devised. One
and only one string of consecutive zeros may be replaced by
|a unicast address|
|a multicast address|
|the loopback address|
|the unspecified addresses|
During the transition period from IPv4 to IPv6, both types of
addresses will coexist on the Internet. IPv4 type addresses in the
IPv6 environment may be written as
In this representation, the IPv4 address is
its IPv6 prefix is
According to [ADARCH] the IPv6 address space will be divided into parts as shown in the following table. 15% of the address space is allocated, the remaining 85% are reserved for future use.
|Allocation||Prefix (binary)||Fraction of Address Space|
|Reserved for NSAP Allocation||0000 001||1/128|
|Reserved for IPX Allocation||0000 010||1/128|
|Provider-Based Unicast Address||010||1/8|
|Reserved for Geographic-Based Unicast Addresses||100||1/8|
|Unassigned||1111 1110 0||1/512|
|Link Local Use Addresses||1111 1110 10||1/1024|
|Site Local Use Addresses||1111 1110 11||1/1024|
|Multicast Addresses||1111 1111||1/256|
Depending on what role an IPv6 node plays in the network, it may have much or little knowlege of the internal structure of the IPv6 address. A host may consider the address to be a contiguous string of 128 bits.
Usually a host will know the link prefix(es) for its link(s) and that part of the address is the interface ID.
|n bits||128-n bits|
|subnet prefix||interface ID|
Hosts on IEEE 802 LANs will probably use an address format similar to this
|n bits||80-n bits||48 bits|
|subscriber prefix||subnet ID||interface ID|
In some cases the network organization that a host belongs to has further partitioned the above subscriber prefix (see Topology).
|s bits||n bits||m bits||128-s-n-m bits|
|subscriber prefix||area ID||subnet ID||interface ID|
0:0:0:0:0:0:0:0 is known as the unspecified
address. It is used to indicate that the address is unknown and must
therefore never be assigned to any node. It is used as source address
during autoconfiguration to indicate
that the host does not know its address. The unspecified address must
not be used as a destination address.
0:0:0:0:0:0:0:1 is the loopback address which
is used by a node to send packets to itself. The address must not be
assigned to any node and must not be sent outside a single node.
There are two kinds of embedded IPv4 addresses. The "IPv4-compatible IPv6 addresses" are used to tunnel IPv6 packets over IPv4 routers.
|80 bits||16 bits||32 bits|
"IPv4-mapped IPv6 addresses" are addresses of nodes that do not support IPv6.
|80 bits||16 bits||32 bits|
The format of provider based unicast addresses is
|3||n bits||m bits||o bits||125-n-m-o bits|
|registry ID||provider ID||subscriber ID||intra-subscriber|
The provider based address format is designed to allow flexible assignment of addresses in a way that makes routing cheap but still allows a multitude of different configurations. [UUALL]
There are two kinds of addresses for local use. The link-local address is used in address autoconfiguration and neighbour discovery (see Autoconfiguration). Routers must not forward packets with link-local source addresses.
|10 bits||n||118-n bits|
Site-local addresses can be used in networks that are not connected to the Internet. If they at some point decide to join the Internet, the site-local prefix must be replaced with a subscriber prefix. Packets with site-local addresses must not be routed outside the site.
|10 bits||n||m||118-n bits|
|subnet ID||interface ID|
Anycast addresses are allocated from the unicast range and are syntactically indistinguishable from unicast addresses (see Anycast).
The IPv6 anycast addresses are taken from any of the unicast address ranges. They differ in the fact that the same address is assigned to several interfaces, which must know that the addresses are anycast addresses. A node sending to an anycast address does not need to know that it is an anycast address.
A packet sent to an anycast address is routed to the "nearest" node that has that address; the measure of distance depends on the routing protocol used. There is little experience of the use of anycast addresses in an internet, and it is expected that the use will mostly be site-local. Routers will respond to several different anycast addresses and in that way support different routing policies.
Currently two restrictions are imposed on IPv6 anycast addresses. [ADARCH]
|n bits||128-n bits|
The IPv4 broadcast address concept has been replaced by multicast addresses. A multicast address identifies a group of nodes, and a node can belong to any number of multicast groups.
The first octet is
11111111) which is
the multicast address prefix. The second octet identifies the type of
multicast address, divided into flags (flgs) and scope (scop).
Permanent multicast addresses have the same meaning in every scope,
e.g. the group id
43h might be assigned to the "NTP
servers group". This means that
FF02::43 identifies all
NTP servers on the same link as the sender, whereas
FF0E::43 identifies all NTP servers on the Internet. It
is evident that multicast addresses of a local scope should be
preferred to global multicast addresses.
Transient multicast addresses have meaning only within a particular
scope, so two different sites can use the same address for different
purposes. The permanent multicast address with the same group ID as a
transient address also has no relationship to the transient
FF02::43 is distinct from
Multicast addresses must not be used as source addresses or appear in any routing headers. Using multicast addresses in this context would make error recovery impossible.
The multicast addresses with the group ID of zero, i.e.
FF0F::, are reserved and will never be assigned to any
multicast group. In addition to these, the following groups are
FF01::1 all node-local nodes
FF02::1 all link-local nodes
FF01::2 all node-local routers
FF02::2 all link-local routers
FF02::C all link-local IPv6 DHCP servers and relay agents
The neighbour discovery protocol uses solicited-node multicast
addresses. They are of the form
XXXX:XXXX is the lower 32 bits of the address. Selecting
the solicited-node address this way often reduces the amount of
multicast groups a node must join, as most of its uni- or anycast
addresses differ only in their prefixes. This is important as a node
must listen to the associated solicited-node addresses for every uni-
and anycast address it has.
[ADARCH] requires that every host recognize the following addresses as referring to itself:
In addition to these, a router must recognize the following addresses as identifying itself:
Street addresses have a clear topology. Everyone who ever has sent a letter has some kind of idea of how the letter is transported from A to B. For example, a letter from Oklahoma, USA to the (imaginary) address of
Mr John Smith
Mannerheimintie 345 A 67
FIN - 00300 HELSINKI
may be transported from the local post office to the Oklahoma central office from where it is flown to Europe, perhaps even straight to Finland. It would then be put with the mail going to Helsinki, and in Helsinki sent to the office of district 00300. Only there would the first two rows be significant; if there was no such address, or Mr Smith never lived there, the letter would be returned, else it would be delivered.
The designers of IPv6 have recognized the need to create topological addresses to make routing easier. The address space is so large that uncontrolled assignment of addresses soon would cause the routing tables to grow too big. [UAALL] presents an architecture for allocating IPv6 unicast addresses in a topologically reasonable manner. Even though the assignment of addresses is partly a policy matter, partly a question of routing, we briefly present the high level division of the addresses proposed.
The object of the unicast address assignment scheme is to create a hierarchy that greatly reduces the work needed to route packets over the Internet. This is achieved by allocating all addresses within a domain so that they have a common prefix. When two domains want to exchange routing information, they only need to pass the domain prefixes to each other. The routers can then be configured to route any packets with those prefixes to the other domain.
The Internet is expected to grow so large that even the "domain" of routing domains will grow too large to handle with a flat address model. It is therefore recommended that domains that are "close" in the physical topology of the Internet are given domain prefixes that themselves have a common prefix. How large the different parts of the prefixes need to be is dictated by the topology and size of the domains, and may vary in different parts of the Internet.
It is recommended that organizational and administrational boundaries should be ignored when assigning domain prefixes. Often the network topology does not reflect these boundaries, which means that assigning addresses according to them would lead to inefficient routing.
In the case of country boundaries the network connectivity seems to follow the country borders quite well. This should be reflected in the assignment of prefixes, but care should be taken as there may well be exceptions from this rule.
The stateless address autoconfiguration process is described in [ADCONF] and is closely related to the Neigbour Discovery protocol. The aim of stateless autoconfiguration is to make connecting machines to the network as easy as possible. In many cases it actually allows you to plug your machine into the network and start using it right away.
For autoconfiguration to work, an interface must be able to provide a unique identifier such as its link-layer address; in IEEE 802 networks the network address will be used. This identifier is then used to create a link-local IP address and all necessary multicast addresses for the node.
The tentative link-local IP address is announced in a Neighbour Solicitation message, which is repeated several times. If no Neighbour Advertisement message is received in response, the address is assigned to the interface. This does not actually verify that the address is unique, as the link may have been broken at the time of the Neighbour Solicitation. Later the Duplicate Address Detection protocol may be used if there is a suspicion that the address is not unique. Before the tentative address is assigned to the interface, the node may only send and receive Neighbour Solicitation and Advertisement messages.
The stateless autoconfiguration protocol is powerful enough to work in large networks with several routers, but larger sites may choose to use the stateful protocol to have more control over how the addresses are assigned. The stateful protocol is described in [DHCPv6] and is beyond the scope of this document.
Autoconfiguration also makes automatic renumbering of the nodes possible. Address prefixes and even addresses themselves have lifetimes that can be used to gracefully fade out old addresses and start using new ones instead. An address that is about to expire first becomes deprecated, which means that no new connections should be established using it, but that it still can be used on existing connections. Once an address expires, it must not be used at all.
The Neighbour Discovery protocol is used to discover local nodes, routers, link-layer addresses and to maintain reachability information based on them. It is described in [NDIP] in a form that assumes the link is broadcast capable. Links that do not support broadcast (e.g. as ATM) will have to extend the protocol to suit their needs.
The following functions are part of the Neighbour Discovery protocol.
To achieve its goals, the Neighbour Descovery protocol defines five packets. These are
The Neighbour Discovery protocol also includes support for a few
Inbound load on a node with several interfaces can be balanced by responding to solicitations with different link-layer addresses.
Anycast addresses can cause several responses to one solicitation, but the responses do not have the Override flag set. This allows the node to choose which of the link-layer addresses it will use.
Proxy nodes may respond with advertisements for nodes not present on the link, but that can be reached through the proxy. These advertisements do not have the override bit set, so if the actual node is present, it takes precedence. This is useful in mobility management.
[NDIP] describes the following conceptual model of a host. An implementation can, and probably will, differ from this model, but must perform the same functions.
|INCOMPLETE||Address resolution in progress.|
|REACHABLE||Has been reachable recently (in tens of seconds)|
|STALE||Not known to be reachable, but no attempt to determine its reachability should be made until traffic is sent to it.|
|DELAY||Give upper layer protocols some time to determine reachability before starting a probe.|
|PROBE|| Unicast Neighbour Solicitation probes are being sent.|
The Destination Cache is consulted, and if the address is not in it, a longest match is done on the Prefix list to determine if the address is link-local. Either way, the next-hop IP address is found, which is either link-local or the address of a router. The Destination Cache contains next-hop information to decrease the amount of next-hop determinations; even if next-hop determination is performed again, the cache entry does not need to be purged, as it can contain other link-layer parameters as well.
The Neighbour Cache is used to find the link-layer address of the destination. If the address is not in the cache Address Resolution is initiated in the INCOMPLETE state and the packet is queued for transmission when the address is resolved. The cache lookup may also result in Unicast Neighbour Solicitation, if the node has not been reachable lately.
When the destination is known to be REACHABLE, the packet can be transmitted.
Multicast addresses are always considered to be link-local, and a separate address resolution algorithm for each link type is required to find the link-local broadcast address to use.
The variables are set to the union of the values received in Router Advertisements. Variables that have only one possible setting are set according to the most recent advertisement. If an advertisement has some values set to "unspecified", the value of the variable must not be changed.
Router Solicitations can be sent when a node attaches to the link. The periodic Router Advertisements may be incomplete, but the response sent to a Router Solicitation is always compete. Before sending the first Router Solicitation, the node should delay for a short random time to avoid race conditions when several nodes are attached to the link simultaneously, for example after a power failure. If no response is received to the Router Solicitations, the node assumes that no routers are present, but will still listen for Router Advertisements in case a router appears on the network.
Address resolution is used to determine the link-layer address of a node whose IP address is on-link. The Neighbour Cache entry is set to INCOMPLETE and a Neighbour Solicitation message is sent to the solicited-node multicast address corresponding to the target IP address. The source link-layer address is sent with the Neighbour Solicitation, so that the response can be sent as unicast. Neighbour Solicitations are retransmitted until a response is received or the maximum limit is reached, which means that the address is unreachable.
When the solicited node receives a Neighbour Solicitation message, the Neighbour Cache entry for the sender is updated and set to the STALE state. This indicates that at least one-way transmission works, but that the return path is still untested. A Neighbour Advertisement with the Solicited flag set is then sent to the soliciting node.
Upon receipt of the Neighbour Advertisement with the Solicited bit set, the soliciting node sets its Neighbour Cache entry to REACHABLE. If the Solicited bit is not set, the message is not a response to the Neighbour Solicitation, and the entry is set to the STALE state.
The node that sent the Neighbour Solicitation knows that the path works both ways, whereas the solicited node only knows that it can receive messages. The solicited node can get knowledge of the return path from upper level protocols, or if that is not possible, by running the Neighbour Unreachability Detection algorithm.
These are the protocol constants used by a host (may wary depending on link type) [NDIP]
|Max. Solicitation Retry Delay||1 second|
|Solicitation Retry Interval||4 seconds|
|Max. Solicitation Retries||3 transmissions|
|Max. Multicast Solicitations||3 transmissions|
|Max. Unicast Solicitations||3 transmissions|
|Max. Anycast Delay||1 second|
|Max. Neighbour Advertisements||3 transmissions|
|Reachable Time||30,000 milliseconds|
|Retransmit Timer||1,000 milliseconds|
|First Probe Delay||5 seconds|
|Min. Random Factor||0.5|
|Max. Random Factor||1.5|
The IPv6 address assignment gives a host several addresses that it responds to. (see Required Addresses) Some hosts may need even more addresses, having several interfaces on different links. Sofar not much research has been done in this field, but several problems exist. Multihomed hosts must determine which interface to use for a transmission, much like routers do. This concept is carried even further in [MANYAD].
Bellovin proposes that IP addresses could be assigned to logical interfaces, so that a node would provide different services at different addresses. A public FTP service could have a well-known name and address, whereas a private service at the same host would use a different address. An even better example is the Archie service, which can be used remotely with an archie client or locally from a telnet prompt. The two services would have different names and addresses, thus eliminating the need to telnet to a certain port.
The ability to use different addresses for different services on the same host also has security implications. Currently a firewall needs to be able to block access to forbidden ports, and to allow connections to public ports. If the two were separate addresses, the only screening needed would be address based which is much more efficient.
It is even conceivable that every user on a host would be assigned an address of his own. This would increase the load on the host, but could provide many useful services. If an address would belong to a user, it could be used for accounting purposes, such as pay-by-use. User-level encryption would also be provided by the same mechanisms that provide host-level encryption without the need for another protocol.
The IPv6 address space along with the new any- and multicast addressing modes make the IPv6 Internet much more flexible than the old Internet. The protocol stack will be more complex, requiring a bit more processing power, but that is more than compensated for by the new features.
Configuring a host for the Internet has never been easy, so the autoconfiguration protocols are a welcome addition. Computer users are growing accustomed to "Plug-and-Play" devices and will appreciate that connecting to the Internet is equally easy. Network maintainers will find that their workload decreases markedly, as the number of misconfigured hosts drops drastically.
The Neighbour Discovery process along with Duplicate Address Detection and Unreachability Detection will probably make the new Internet more robust. Nodes react rapidly to changes in the network architecture and do not need to be reconfigured manually. Even larger renumbering operations that often are very error prone may be performed almost automatically and with better chances of success.

|Host||A computer on a network|
|Interface||Hardware connecting a host to a network|

Simulation-driven Design Optimization And Modeling For Microwave Engineering
Slawomir Koziel, Xin-She Yang, Qi-Jun Zhang
Computer-aided full-wave electromagnetic (EM) analysis has been used in microwave engineering for the past decade. Initially, its main application area was design verification. Today, EM-simulation-driven optimization and design closure become increasingly important due to the complexity of microwave structures and increasing demands for accuracy. In many situations, theoretical models of microwave structures can only be used to yield the initial designs that need to be further fine-tuned to meet given performance requirements. In addition, EM-based design is a must for a growing number of microwave devices such as ultra-wideband (UWB) antennas, dielectric resonator antennas and substrate-integrated circuits. For circuits like these, no design-ready theoretical models are available, so design improvement can only be obtained through geometry adjustments based on repetitive, time-consuming simulations. On the other hand, various interactions between microwave devices and their environment, such as feeding structures and housing, must be taken into account, and this is only possible through full-wave EM analysis.
Electromagnetic simulations can be highly accurate, but they tend to be computationally expensive. Therefore, practical design optimization methods have to be computationally efficient, so that the number of CPU-intensive high-fidelity EM simulations is reduced as much as possible during the design process. For the same reasons, techniques for creating fast yet accurate models of microwave structures become crucially important.
In this edited book, the authors strive to review the state-of-the-art simulation-driven microwave design optimization and modeling. A group of international experts specialized in various aspects of microwave computer-aided design summarize and review a wide range of the latest developments and real-world applications. Topics include conventional and surrogate-based design optimization techniques, methods exploiting adjoint sensitivity, simulation-based tuning, space mapping, and several modeling methodologies, such as artificial neural networks and kriging. Applications and case studies include microwave filters, antennas, substrate integrated structures and various active components and circuits. The book also contains a few introductory chapters highlighting the fundamentals of optimization and modeling, gradient-based and derivative-free algorithms, metaheuristics, and surrogate-based optimization techniques, as well as finite difference and finite element methods.Contents:

Zenith is best known for the first practical wireless TV remote control, the Space Command, developed in 1956. A box advertising a remote control system often referred to as "Space Command Tuning". The Zenith remote, called the Space Command or Zenith Clicker, was an ultrasonic remote that used hammers hitting aluminium rods within the remote. So no batteries required! These rods rang at certain frequencies – forcing the TV to turn on or off, changing the channel or muting or un-muting the sound. The television interpreted the various tones as commands to switch the channel up or down, mute the sound, or turn itself on or off. The RC was an immediate hit, despite increasing the cost of compatible Zenith sets by a staggering 30 percent!
The original television remote control was a wired version, released in 1950, that soon attracted complaints about an unsightly length of cable from the viewer's chair to the television receiver. Eugene F. McDonald, Zenith President and founder, ordered his engineers to develop a wireless version, but the use of radio waves was soon discounted due to poor interference rejection inherent in 1950s radio receivers. Lead engineer Robert Adler then suggested that ultrasonic sound be used as a trigger mechanism. The buttons struck the rods with a nearly whisper-quiet sound (it earned the nickname 'The Clicker') but it ushered in the era of ultrasound remotes – a method used well into the 1980s.
The frequencies used in the Space Command remote were too high for the human ear to pick up, though they could be discernible to animals such as dogs and cats. There was a story going round at Zenith that during testing, one female lab assistant flinched every time the device was tested, due to her sharp sense of hearing.
The Zenith Space Command looked like a Star Trek prop, with just four protruding buttons – worlds away from today's devices which might crowd several dozen onto a slim rectangle of plastic.
The Space Command 600 was introduced in 1965 and this design was in use until the end of 1972. The 600 had an additional, distinctive feature, it could also adjust color hues.
The ultrasonic sound technology used in remote controles endured until the dawn of infrared in the 1980s.
Some models use the word Commander, for example the Space Commander 300.

Two forgotten technology stocks are popping up today for pullbacks. Both were featured in last week’s earnings recap.
AT&T (T) gapped up last week after a surprisingly strong quarter. The telecom giant outperformed on both mobile and broadband subscribers. Now it may have an additional boost from 5G rollouts. T retraced the bullish gap and is holding near long-term lows. It also averages more than 150,000 options contracts per day.
Ericsson (ERIC) also surged last week, following its second consecutive strong quarter. The Swedish telecom supplier seems to have the double-impact of a long-term turnaround plus 5G demand. It’s been viewed as an alternate to Huawei.

Bandwidth Meter Pro provides users with detailed information regarding a lot of network parameters. It is a well-designed application that, in spite of the absence of an actual user-interface, will help network administrators to keep track of the bandwidth usage. Bandwidth Meter Pro supports monitoring all the popular network connections (wireless, LAN, ISDN, VPN, and many more.)
Bandwidth Meter Pro proves to be a reliable tool when it comes to measuring the bandwidth speed for various network types. It is also able to monitor multiple connections at the same time. It displays traffic data in a graphical manner and allows the user to customize the graphs that it provides.
Some may consider the lack of a graphical user-interface to be a drawback for Bandwidth Meter Pro, but as far as I’m concerned, the program includes a lot of useful tools that compensate that issue. The program runs silently in the system tray and will display network data only at user’s request. An important feature of Bandwidth Meter Pro is its ability to generate detailed daily, weekly, or monthly traffic reports. Also, the included stopwatch will help users monitor their connection for a specific period of time.
I consider Bandwidth Metter Pro to be a reliable solution for anyone who wants to know more about their network or Internet connections.

No name is more closely associated with high-end audio amplifiers than that of Dan D’Agostino. During his career of more than 35 years, D’Agostino pioneered countless advances in the design of amplifiers, preamplifiers, CD players, and surround-sound processors. He is known as the audio industry’s most passionate promoter of high-quality, high-powered amplification. Makers of the world’s finest loudspeakers rely on D’Agostino-designed amplifiers for their most important demonstrations.
Dan D’Agostino was founder and chief engineer of Krell Industries through 2009. Since the inception of DDMAS in 2011, energized with a new organization and new state-of-the-art designs, the products that bear his name not only achieve new levels of sound quality, they also look like nothing else in the industry. The new designs combine an elegant aesthetic flair coupled to inventive circuit topologies and innovative materials.
Starting with the Momentum Mono amplifier, the D’Agostino product line now extends upwards to the awe inspiring Relentless Mono amplifier and outwards to the new Progression Integrated amplifier. The Relentless Mono Amplifier is an all-out assault on the amplifier category. Capable of driving any speaker to its fullest capability, the extraordinary power output of the Relentless Mono is only matched by its sublime low volume sound quality. The Progression Integrated amplifier connects the high-performance core of D’Agostino products to the exciting world of streaming audio with Tidal, Quobuz, and Spotify services as standard offerings.
As impressive as these designs may sound on paper, the only way you can truly appreciate their warmth, detail and unmatched beauty is to experience them at your nearest Dan D’Agostino Master Audio Systems dealer.
Combining engrossing sound quality, a flexible platform, and striking aesthetics, the Relentless Preamplifier is the ultimate centerpiece for a truly brilliant audio system.
Created for uncompromising listeners and needing three chassis to execute, the Relentless Preamplifier elevates every aspect of preamplifier design. Individual audio chassis and power sections ensure complete isolation from noise. Audio and power signals are carried through interlocking feet shortening signal feeds to the absolute minimum.
The standard model can be augmented with a plug-in digital streaming module including legacy digital inputs, network, and internet music streaming. Tidal, Qobuz, Spotify, and Roon are all directly supported. An iOS app makes for easy, intuitive operation.
The new Relentless Preamplifier is the ultimate in preamplifier design. The preamplifier plays a critical role in musical playback; the point in the reproduction stage when the music signal is particularly susceptible to compromise through noise and distortion. The use of three separate chassis in the design of the Relentless Preamplifier—a dedicated audio chassis for each channel separated by a power supply/control section—addresses these challenges and brings other benefits as well.
Positioned between the two audio channels, the power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical preamplifier circuits. Internal line conditioning circuitry filters RF noise on the AC power and compensates for asymmetric power waveforms and DC on the mains. Power for the preamplifier stages comes from two 150 VA toroidal transformers – one dedicated to the analog circuitry and one for the digital and control circuitry. These transformers drive an 8-amp bridge rectifier and 26,400 microfarads of filter capacitance. The two regulators for the analog stages are scaled-down versions of those used in the Relentless Mono amplifier. The separate digital regulator is a monolithic platform with thermal and current limiting protection in the unlikely event of a fault. The Relentless Preamplifier has nearly as much power supply capability as many power amplifiers.
The input stage in each mono preamplifier is the result of a design experiment for a circuit that hadn’t been used in any previous D’Agostino preamplifier. As part of development, a version was tested in the existing Momentum Preamplifier. The overwhelmingly positive results led directly to the launch of the Momentum HD Preamplifier. From there, the fullest expression of this idea was developed, and the Relentless Preamplifier was underway.
The audio circuit topology starts with a new discrete differential FET input stage featuring a voltage input signal capability of an extraordinary 30 volts. With an input impedance of over 1 M Ohm, the Relentless Preamplifier’s front end is immune to source related electrical issues. In normal operation, component heating can lead to performance and sonic degradation. Developed specifically for the Relentless Preamplifier, a unique circuit maintains a stable bias so that temperature related anomalies are offset thus preserving performance during extended listening.
Featuring only balanced XLR inputs the Relentless Preamplifier topology rejects common-mode input noise over an unusually wide bandwidth. All signal gain is realized in the current domain using proprietary multiple-output current mirrors with nearly 30 times the linearity of other designs. Executed with four-layer circuit boards for superior signal quality. The use of four-layer boards dramatically reduces distortion and propagation levels as compared to the more commonplace, two layer boards.
The analog and digital circuit elements are isolated, including ground planes, from each other. Where necessary, digital control signals are optically coupled to analog circuits. The signal switching relays are hermetically sealed and use gold-plated contacts for maximum signal integrity.
Utilizing no negative feedback anywhere, core D’Agostino circuit concepts include a signal path that is fully complementary and balanced from input to output achieving a frequency response flat to 120 kHz.. The overall result is a musically dense and dynamically rich signal presented to the balanced outputs.
Arguably, the most striking element of the Relentless Preamplifier is the pair of volume controls fronting the two audio chassis. Volume control circuits are often overlooked, if not actively minimized, in preamplifier designs. This is not the case in the Relentless Preamplifier. Each volume control is constructed using 14 separate metal components ensuring the smoothest response and control of the military-grade, high-linearity solid-state switches and discrete precision resistors employed in the volume circuit. The bandwidth and transient response of the Relentless Preamplifier is completely unaffected by the volume setting. As a result, high frequencies sound especially smooth and extended, and music emerges from “jet black” silence.
The volume settings are displayed via the elegant swiss watch inspired volume wands or can be displayed numerically, from 0 to 99.
The Relentless Preamplifier is a two source/two zone preamplifier. This means that the Relentless Preamplifier can simultaneously control the switching and volume of two sources in two separate rooms or zones. Listening sources may be two analog sources or when equipped with the optional digital streaming module, one digital source and one analog source. In a one zone system, either volume control will adjust volume in the main room or Zone 1. If two zone operation is desired, the upper volume control manages the Zone 1 volume and the lower volume control adjusts the Zone 2 volume.
Housed in machined aluminum and copper, the Relentless Preamplifier remote control is a comfortable design operated via touch pad. Control buttons are minimized with most of the operation executed by navigating via a tactile touch pad. Bluetooth 5.0 technology extends the usable range of the remote control and eliminates the line-of-sight issues that plague conventional infrared designs. New for the Relentless Preamplifier is bi-directional remote-control functionality. All adjustments made on the Relentless Preamplifier front panel are reflected on the remote control’s display screen including input, volume, and balance selections.

Often the forgotten component of any network design, your computer network cabling infrastructure can become your biggest headache. Designing and planning a structured cable plant design for your building or office simplifies management of moves, adds and changes, which comprise a majority of your day-to-day administration headaches and provides you with a reliable infrastructure for data transport. Having designed and implemented systems for clients throughout Michigan, our expertise will help you in implementing a "transparent", structured cabling system that allows you to concentrate on more important issues, such as running your network.
ITS designs, installs, and maintains structured voice, data (computer network cabling, ie: Ethernet) and fiber-optic cabling systems (single and multi-mode fiber optic) based upon the specific needs of your company or business. Our structured cabling system designs:
Allow for adds, moves, and changes (MACs) quickly and easily.
Allow growth with minimal incremental cost.
Accommodate a wide variety of hardware configurations and network topologies
Integrate with any computer and telephone system to allow for maximum interchangeability and flexibility.
Utilize high-quality, industry-leading components with stringent manufacturer warranties.
Are guaranteed to be certified to industry-standard specifications, such as TIA/EIA-568-B Commercial Building Telecommunications Cabling Standard.
Pride in workmanship still counts! Installation services include implementation of any cabling design and our maintenance service extends to providing support for any of our installations as well as non-ITS installations. Considering that a typical Ethernet infrastructure will be in place for 20-30 years, and that critical technologies such as voice/telephone (VoIP), and video surveillance (IP-based video), that have traditionally been installed on separate copper and coaxial networks are now becoming part of the LAN network infrastructure, we feel that it's more critical than it ever has been to select the right infrastructure partner from the start.
One of the biggest advantages of working with ITS on your next voice or data cabling or fiber project is that we are a one-stop solution, our expertise doesn't end at the wall jack. Once we have completed your cabling or fiber project, we won't leave you hanging when you ask us about power, cooling, networking or telephony issues. Why? Because we are experts in the design, integration, installation and support of highly scalable power and cooling solutions. What this all means to you is that this consolidated training and expertise allows us to bring a complete solution to the table because we understand the data center from the copper and fiber, to the metals, racks and cable raceway, to the power and cooling needs, to the final integration with your voice and data systems, wireless infrastructure and VoIP systems. We strive to provide our customers with comprehensive solutions. And that doesn't mean that you have to be huge to call us, we're happy to work on small projects for customers only needing a drop or two, all the way up to multi-story, multi-faceted datacenters. Every customer is important and appreciated here!
Testing and Certification
Many people "install" network cabling, but fail to actually test and certify it. There is a difference. Simply installing cabling and then running a "tester" on it is not the same as certifying that the voice and data cabling will actually meet the rated speed that you're paying for. Devices may light up at both ends of the connection, but how do you really know that you're getting 100Mb, and maybe not 10Mb? When network problems arise, do you really want to have to worry about the wiring being suspect?
ITS Testing and Certification Reports because of the demanding requirements of today's network infrastructure, the only true way to confirm that your cable infrastructure actually meets the specifications and quality level that you've purchased is to test and certify it. We test and certify all twisted-pair cabling for Category 5/5e/6 compliance (where applicable), including continuity, proper polarity, crossed-pairs, NEXT, and shorts with an industry-standard Fluke DTX Level IV cable certifier, or equivalent. We also test and certify all our fiber optic cabling installations. Once ITS completes an infrastructure installation, you can be assured that your physical infrastructure meets the specs that you paid for. We also maintain an archive copy of your cable/fiber scans on site, so that they can be provided in the future if you've lost your copy.
Our voice and data cabling technicians are certified too. We do not hire the lowest cost personnel that we can find or subcontract our work out to someone else. We look for high quality, professional, trained and certified full-time employees, and then continue to train them to stay abreast of the latest industry standards and performance requirements from BICSI, EIA/TIA, CompTIA, etc. We take great pride in the high quality of the workmanship that we provide and we back it up with a Lifetime Workmanship Warranty.
Graphically Document Network and Cabling Systems
Network and cabling system documentation is generated graphically using Microsoft Visio or AutoCAD. We can produce professional full color illustrations and documentation. These services include logical network design, cable routing, punch block layout, and patch panel systems for any network. This is in addition to our cable and fiber optic certification scan reports which are provided upon completion of every job.
High Quality Materials
Our infrastructure solutions primarily use industry-leading Panduit and General Cable solutions, which, when installed together, provide the customer with a 25-year product warranty. However, we have installed most major vendors products and can accommodate any specific vendor requests, including, but not limited to: Panduit, AllenTel, AT&T/Lucent, Belden, Berk-Tek, Cablofil, Chatsworth, General Cable, Hubbell, Krone, Leviton, Mohawk/CDT, Nordx/CDT, Ortronics, Siemon and Wiremold.
ITS stands behind our work with a unique Lifetime Warranty, which states that we warrant the workmanship of our computer cabling for the lifetime of its installation. Materials are warranted for one (1) year, or the duration of the manufacturer's warranty whichever is longer.
Computer Room & Data Center Design
ITS has the design expertise to develop programming information and specifications for Computer Rooms, Data Centers, Telecommunications Rooms, and Equipment Closets.
We can provide the following services: Inventory and documentation of existing client equipment. Documentation of existing voice and data circuits and facilities. Coordination with equipment vendors. Space planning and design development for new equipment rooms. Comprehensive specifications for raised floors and overhead cable management. Complete equipment matrix detailing power, HVAC, loading, and space requirements. Visio/CAD drawings showing layout of equipment rooms, and equipment racks. Design of in-room fiber and copper cabling for complete equipment connectivity.
Categories of Copper Cabling
Customers often ask what the differences are between the various types of cable (ie: Cat3, Cat5, etc.). In a nutshell, the higher the number, the better the performance, and accordingly, the higher the price tag. The most common types of cabling are Category 3 (used primarily for voice today), Category 5E (the most common type of cabling, used for both voice and data, and also supports Gigabit Ethernet), and Category 6. Customers sometimes request Category 6 because they think it's a requirement for Gigabit Ethernet, which isn't quite correct. Gigabit Ethernet can run on Category 5 cabling, however, Category 6 will perform better. The key is the bandwidth the cable supports.
Category 6 is rated at 250Mhz (and the newest Category 6a specifies 500Mhz), whereas Category 5E is rated at 100Mhz. The higher megahertz support allows cabling to handle the greater amount of noise and crosstalk that occurs on a wire when faster (ie: gigabit and 10G) connections are running on that wire. When signals are run at a higher frequency that the cabling is not rated for, it can cause errors and anomalies.
So what are the cost variances? Generally speaking, you can expect to pay a 20% price premium between Cat6 and Cat5E, and a 50% price premium between Cat 5E and Cat 6a.

Security Lab researchers reveal how smart devices can be turned into surveillance devices with music
Researchers from the Allen School’s Networks & Mobile Systems Lab and Security and Privacy Research Lab teamed up on a new project, CovertBand, to demonstrate how smart devices can be converted into surveillance tools capable of secretly tracking the body movements and activities of users and their companions. CovertBand turns off-the-shelf devices into active sonar systems with the help of acoustic pulses concealed in music. The team’s findings reveal how increasingly popular smart home assistants and other connected devices could be used to compromise users’ privacy in their own homes — even from half a world away.
“Most of today’s smart devices including smart TVs, Google Home, Amazon Echo and smartphones come with built-in microphones and speaker systems — which lets us use them to play music, record video and audio tracks, have phone conversations or participate in videoconferencing,” Allen School Ph.D. student and co-lead author Rajalakshmi Nandakumar told UW News. “But that also means that these devices have the basic components in place to make them vulnerable to attack.”
As fellow author and Ph.D. student Alex Takakuwa points out, “Other surveillance approaches require specialized hardware. CovertBand shows for the first time that through-barrier surveillance is possible using no hardware beyond what smart devices already have.”
CovertBand relies on repetitive acoustic pulses in the range of 18 to 20 kHz. While that is typically low enough that most adults are unlikely to pick up on the signals, young people and pets might — and an audible volume is required for more distant surveillance or to pick up activity through walls. To get around this, the team found that they could disguise the pulses under a layer of music, with repetitive, percussive beats the most effective at hiding the additional sound.
“To our knowledge, this is the first time anyone has demonstrated that it is possible to convert smart commodity devices into active sonar systems using music,” said Allen School professor and co-author Shyam Gollakota.
By connecting a smartphone to a portable speaker or flat-screen TV, the researchers discovered they could use the data collected through CovertBand to accurately identify repetitive movements such as walking, jumping, and exercising up to a distance of six meters within line of sight, and up to three meters through walls. Having proven the concept, researchers believe a combination of more data and the use of machine learning tools would enable rapid classification of a greater variety of movements — and perhaps enable the identification of the individual making them.
With CovertBand, Allen School researchers have identified a plausible threat, given the increasing ubiquity of these devices in our pockets and in our living rooms. But our embrace of emerging technologies needn’t end on a sour note. As professor and co-author Tadayoshi Kohno points out, when it comes to cybersecurity, knowledge is power.
“We’re providing education about what is possible and what capabilities the general public might not know about, so that people can be aware and can build defenses against this,” he said.

Over the past 30 years, fiber lasers have gradually become a premier technology in the industrial coding and marking field. Invented by American physicist Dr. Elias Snitzer in 1961, fiber laser systems were largely used for niche applications before technical advancements in the 1980s and 1990s allowed them to be used for industrial marking and cutting applications. Today, fiber lasers, alongside CO2 laser marking systems, are considered to be among the best coding technologies on the market.
The popularity of fiber laser marking machines is largely attributed to their ability to mark non-organic materials. Fiber laser systems produce wavelengths 10 times shorter than CO2 systems. In many cases, materials that cannot be marked by wavelengths produced by CO2 lasers can be marked with a fiber laser marking system. The ability of materials to absorb the shorter wavelength from a fiber laser creates a contrast, color change, or surface distortion in the substrate. Fiber lasers use the same marking delivery method as CO2 laser marking systems and have the ability to mark high-density materials like rigid plastics, steel, and aluminum, expanding the applications they can be used for.
However, not all fiber laser marking machines are created equal. If you’re on the search for a fiber laser system for your operation, here’s what you need to know.
When considering which fiber laser system will work best for you, several factors will guide your search. The most obvious starting point is confirming the machine is well-suited for marking applications. There are many fiber laser systems on the market, including models that are best suited for welding, drilling, and cutting applications.
The systems designed for welding, drilling, and cutting most often utilize continuous-wave beams as opposed to marking systems that typically utilize pulsed beams. While some fiber laser systems can generate both beam outputs, it’s essential to know that your potential system choices will generate the appropriate beam for your needs.
Beam output similarly affects which materials the system can mark and how quickly. Consequently, it’s essential to ask the following questions while searching for a laser marking system:
It’s important to determine the effectiveness of the laser marking system to produce the desired throughput and quality of the marking application. Always test the exact material to be marked with the exact laser marking system you intend to use.
A marking application must be evaluated thoroughly. Factors to consider include:
With this information, you should be able to find the best fiber laser marking machine to fit your operational needs. Next, we’ll look at the best places to begin your search.
As one of today’s premium marking technologies, fiber laser systems are available from a variety of sources. However, there are a few laser companies that maintain higher profiles than their competitors. To begin your fiber laser system search, we recommend starting with these five businesses:
Headquartered in Ditzingen, Germany, Trumpf has been manufacturing and distributing industrial equipment for nearly 100 years. It first entered the laser market by creating its own CO2 systems in the mid-1980s, and now it offers a wide range of laser systems, including its flagship fiber laser model, the TruFiber.
Compatible with stainless steel, titanium, aluminum, and copper, as well as plastics and textiles, TruFiber systems use pulsed beams to perform marking applications. To meet the needs of differently-sized businesses, TruFiber systems are available in different models, ranging from the high-powered TruFiber P to the compact TruMicro Series 2000.
Since 1974, Japanese company Keyence has kept a high international profile in the coding and marking industry. Known in the industrial printer sector for its continuous inkjet models, it’s also active in the fiber laser field, where its MD-F Series systems are widely popular.
Keyence differentiates MD-F Series fiber laser machines from the competition by focusing on its “Wobble Control,” i.e. the MD-F system’s circular marking pattern. Conventional laser systems mark materials by creating a series of overlapping single lines. In contrast, MD-F Series lasers are moved in circular patterns, keeping the energy more highly concentrated and thus more effective.
A titan of industrial printing, Domino Printing Sciences is one of the biggest names in the coding and marking industry. It first gained its reputation by designing high-powered continuous inkjet systems in the 1970s, but in August 1994, it expanded its product portfolio to include laser marking systems. Before long, Domino’s laser marking systems were adopted by some of the biggest companies in the world, including Dr. Pepper.
Today, Domino’s top fiber laser option is the F720i. Designed for use on industrial canning lines, the F720i fiber laser can mark up to 100,000 cans per hour with high-quality, fully traceable codes. Further, the system is designed to resist the challenging elements commonly found in industrial canning environments, such as high humidity, temperature changes, and sugar-filled air. As a result, the F270i is capable of delivering long periods of extended uptime for maximum efficiency.

Today meeting planners can share their presentations with individual attendees via Apple iPad, making each event more memorable and the sessions more engaging
London – 22, February 2012 – With the adoption of mobile technologies growing at a rapid rate, PSAV® Presentation Services is introducing the iMeeting Experience to make event presentations more engaging. Utilising the Apple® iPad®, meeting planners can instantly share content from their laptop directly onto iPads® provided to event attendees.
PSAV is a global supplier of audiovisual services and event technologies to decision makers responsible for organising meetings, conferences, and events worldwide.
The work of the company’s multinational team spans the globe, delivering the best in video & projection, lighting, set design and construction, sound, staging, event IT support, rigging, high-definition event videoconferencing and now, power testing.
“PSAV is known around the globe for using technology to make events memorable and engaging, ” said PSAV Managing Director Stephan Earl. “By offering each meeting participant an Apple iPad, meeting planners are able to connect directly to the content via an iPad for easy viewing. The use of this technology makes meetings more personal and helps attendees to better retain the message. Meeting planners hosting events across Europe can quickly deliver a one-of-a-kind event with the iMeeting Experience from PSAV. ”
Each iMeeting package includes: iPad devices with table stands, a high-speed WiFi router and a presentation computer. “In the past, meeting planners were limited to using screens and projectors, portable monitors or bulky hand-held audience response devices to share their message and interact one-on-one with their delegates, ” Earl said. “Today iPads are
removing communication obstacles by delivering content in a format that most consumers are familiar with today.”
In the fourth quarter 2011, Apple sold 11.12 million iPad devices, up 166% over the year-ago quarter. With consumers purchasing this tablet device in record numbers across the globe, it only makes sense that meeting planners incorporate this in-demand technology into their events. Whether it’s used to share information during a small educational session or to send bids for a private auction, using iPads in the meetings environment is here to stay, and it’s changing the way meetings will be conducted now and long into the future. “Meeting planners can continue to use conventional meeting technology and now augment that with new technologies that enhance the experience and keep attendees engaged and ‘wowed,’ ” said Steven Short, PSAV Vice President, Interactive Services. “In addition to using the iPad as a display, PSAV is also a Mobile Event App provider. Our Express App is available in the U.S. today and coming soon to Europe for iPhone, Android, and BlackBerry devices as well as a Mobile Web version which can be used on any web enabled device.Encompassing
nine of the most common features requested for Mobile Apps, the PSAV Mobile Event Express allows clients to fully harness the power of their mobile device.
“MobileEvent™ Express automatically sends out regular updates to attendees, helping presenters keep everyone on the same page with the latest information,” he said. “Offering a mobile option cuts down on the need to print conference materials and mail information to attendees before/after the event takes place. In this way, PSAV’s Mobile Solutions enable a ‘green experience’ for the facility, the meeting planner and the attendee. Facility information can also be made available to meeting goers via the Mobile App to help increase on-site spending, either at the hotel or conference center. ”

In the fast-paced world of organization, efficient communication is essential for success. Clear and nonstop lines of interaction enable companies to collaborate efficiently, make decisions swiftly, and also supply superb client service. One effective tool that has actually been changing service communication is the PBX (Personal Branch Exchange) telephone system.
A PBX telephone system is a sophisticated telephone systems option that allows services to handle their internal and also outside phone calls efficiently. It enables companies to manage a large quantity of calls by providing features such as call directing, call forwarding, voicemail, as well as conferencing abilities. This system functions by connecting several phones within a company and giving accessibility to exterior phone lines.
One of the vital advantages of a PBX telephone system is its capacity to simplify interaction within a company. By connecting all workers through a single phone system, it eliminates the requirement for different phone lines for each person. This not only decreases prices yet also streamlines inner interaction, permitting workers to reach each other promptly and quickly.
Another benefit of a PBX system is its versatility and scalability. As organizations grow and broaden, their interaction requirements also progress. A PBX system can conveniently accommodate these changes by adding or getting rid of phone lines or expansions as needed. This scalability makes certain that businesses can adapt their communication framework to suit their details demands, without the requirement for significant financial investments or overhauls.
Moreover, a PBX telephone system provides various attributes that improve performance and also efficiency. Call forwarding enables workers to get contact their mobile phones or other gadgets, making sure that they are constantly easily accessible, also when they are away from their desks.

Each year, new technologies rise and fall, sometimes making an impact on our daily lives and other times barely leaving a trace. One category of emerging technologies that has the widest variety is the Internet of Things or IoT.
Someone who works for an Internet of Things (IoT) software company, the frequently asked question will be what is IOT?
It is defined as, A system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
Let’s see the simple explanation of the Internet of Things(IOT), it means that internet connection is the most valuable thing which benefit us in all terms, from calling & reading books to watching movies & news.
The point is that connecting things to the internet yields many amazing benefits. We’ve all seen these benefits with our smartphones, laptops, and tablets, but this is true for everything else too.
The Internet of Things is actually a pretty simple concept, it means connecting all the things in the world to the internet.
The confusion arises in your mind because there are so many examples and possibilities in IoT. To understand the benefits of connecting things to the internet. We should firstly connect everything to the internet.
When something is connected to the internet it means that it can send information or receive information. This ability to send or receive information makes things smart.
Let’s take smartphones as an example. we can listen to just about any song in the world, but it’s not because your phone has every song stored on it but it’s because every song is stored somewhere else, where your phone can send information (asking for that song) and then receive information (streaming that song on your phone).
A thing doesn’t need to have storage or a computer inside, but it needs to connect.
In the Internet of Things, all the things that are being connected to the internet can be put into three categories:
- Things that collect information and then send it.
- Things that receive information and then act on it.
- Things that do both.
And all three of these have enormous benefits that feed on each other.
Collecting and sending information means sensors. It could be temperature sensors, motion sensors, moisture sensors, air quality sensors, light sensors, and many more. These sensors with a connection, allow us to automatically collect information from the environment which allows us to make more intelligent decisions.
On the farm, automatically getting information about the soil moisture can tell farmers exactly when their crops need to be watered. Instead of watering too much (which can be an expensive over-use of irrigation systems) or watering too little (which can be an expensive loss of crops), the farmer can ensure that crops get exactly the right amount of water. More money for farmers and more food for the world!
Just as human senses, we are able to smell, taste, feel, and hear. Machines have sensors that make them sense the world.
We’re all very familiar with machines getting information and then responding. Your printer receives a document and it prints it. Your car receives a signal from your car keys and the doors open and many more.
The real power of the Internet of Things arises when things can do both of the above. Things that collect information and send it, but also receive information and act on it.
Kevin Ashton, co-founder of the Auto-ID Centre at MIT, first mentioned the internet of things in a presentation he made to Procter & Gamble (P&G) in 1999. Wanting to bring radio frequency ID (RFID) to the attention of P&G’s senior management, Ashton called his presentation “Internet of Things” to incorporate the cool new trend of 1999.
Let’s quickly go back to the farming example. The sensors can collect information about the soil moisture to tell the farmer how much to water the crops, but you don’t actually need the farmer. Instead, the irrigation system can automatically turn on as needed, based on how much moisture is in the soil.
You can take it a step further too. If the irrigation system receives information about the weather from its internet connection, it can also know when it’s going to rain and decide not to water the crops today because they’ll be watered by the rain anyways.
And it doesn’t stop there! All this information about the soil moisture, how much the irrigation system is watering the crops, and how well the crops actually grow can be collected and sent to supercomputers that run amazing algorithms that can make sense of all this information.
And that’s just one kind of sensor. Add in other sensors like light, air quality, and temperature, and these algorithms can learn much more. With dozens, hundreds, thousands of farms all collecting this information, these algorithms can create incredible insights into how to make crops grow the best, helping to feed the world.
As you can see from these Internet of Things examples, the future of IoT is a bright one. As new innovations emerge about how best to use IoT products, it will be interesting to see which way this technology heads.

The levels discussed here are probably irrelevant to any practical application.
This is a silly topic, but there’s a slight chance it might help someone troubleshoot something, someday.
Here is an FFT of an A-grade E1DA Cosmos ADC with nothing plugged in. The settings are unreasonable; 160 averages of 4M Length: about 2 hours of data collection. This was taken with input set to 1.7V, mono mode (summing both channels).
Almost perfect white noise spectrum, with only a bit of low frequency rise. The chart starts at 2Hz so performance is better than it looks at first glance. With these settings the white noise is -187dBFS at 1kHz.
The mains noise is a barely visible -184dBFS blip at 60Hz; not remotely measurable in any reasonable test suite. This is plugged into the front USB port on a desktop PC, and with the input impedance set to 640Ω.
Mains noise increases slightly to -182dBFS when the input is set to 10V (3.84kΩ input impedance).
“Shorting” the input makes the mains noise disappear but otherwise has no significant effect on the noise level. This was taken using a 10.4Ω balanced dummy load to ground, on the 10V input setting. If I had to guess, it looks like the mains noise is dominated by bias/leakage current over the input resistor. Levels this low indicates that the OPA2156’s more robust input specs (aside from noise) compared to the OPA1612 wouldn’t have any practical advantage as the input in this scenario.
Miscellaneous external tests (not relevant to Cosmos ADC performance)
Now with a 30cm XLR Y-splitter cable plugged in. This type of cable is normally required to take measurements in summing mode. The cable itself was left dangling in midair to prevent it from touching anything. A much lower FFT length and averaging was used for this test, so the broadband noise level is not comparable to the tests above. Mains noise has jumped to -161dBFS. This goes away when the input pins are shorted (and as a result is likely not present in actual measurements).
This may look significant compared to the charts above, but this level of mains noise probably isn’t relevant. It is much more pronounced than before, but has practically no effect on the overall noise (still orders of magnitude below the RMS white noise level, which has remained unchanged). APx555 charts typically set the Y-minimum at -160dBr, so this level of noise wouldn’t even be visible on those graphs.
This measurement is with a unibody metal XLR to 1/4″ TS adapter plugged in. This adapter shorts XLR pins 1 and 3 to the connector shell. Despite being much smaller than the Y-splitter cable, it has significantly higher mains noise, enough to reduce the overall noise performance by 1.5dB.
It also introduces a new spray of spuriae previously unseen on any graphs, which all appear to be odd-order harmonics of the mains fundamental.
Connecting a function generator, 1Vpp 1kHz, across XLR pin 1 and the connector shell, produces the above. Note that the FFT length and averaging are different, so the broadband noise levels are not comparable to the other tests. I didn’t verify whether the function generator actually output 1Vpp (doubtful since the load impedance was almost zero). Measuring pin 1 and the connector shell directly at the ADC (nothing plugged in) show that they are shorted together (or at the very least have a low resistance between them); likely they are both attached to ground. In other words, injecting a signal between the two ground inputs, presumably between the chassis and signal grounds, produces something measurable; the two grounds are not connected at the input.
Shorting the two grounds together doesn’t seem to measure any different from an open circuit (not pictured). Perhaps this changes when connected to an actual input with actual current (not tested).

It's a reality : Microsoft has announced, November 7th, the end of Windows Live Messenger for 2013.
The instant messaging service, launched on 1999 as "Microsoft Network Messenger" (MSN), became one of the most popular. With the acquisition of Skype in May 2011 (for more than $ 8,5 B, about 6 B €), both services are duplicated : Skype allows users to send instant messages, like Messenger.
Windows Live Messenger will disappear on 2013, but it will not be of a technical point of view : "Skype is moving from a P2P service to a modern, suitable for mobile devices" said The Verge website.
Thus, Messenger will not disappear completely. "Skype and Messenger meet", said Tony Bates, Microsoft's head.

Video communication has gained immense popularity in recent years, largely due to the widespread adoption of high-speed internet and improved video conferencing technology. Platforms like Zoom, Microsoft Teams, and Cisco Webex have become essential for virtual meetings, webinars, and remote training sessions. Video communication offers a more personal and engaging way to interact with colleagues, regardless of location. It allows facial expressions, body language, and visual aids to be part of the conversation, which is especially important for building relationships and conveying complex information. Additionally, it reduces the feeling of isolation that remote workers may experience.
Social Intranet and Employee Engagement Platforms
Many organizations embrace social intranet and employee engagement platforms to foster community and streamline internal communication. These platforms, such as Yammer, Workplace by Facebook, and Jive, provide a digital space where employees can share updates, collaborate on projects, and connect with colleagues from different departments. By incorporating social media elements, these platforms encourage employees to interact and share knowledge more informally and transparently. They also serve as a centralized hub for important company announcements, policies, and resources, ensuring employees have easy access to the information they need.
Data Analytics for Insights
Technology has enabled organizations to collect and analyze internal communication patterns and employee engagement data. This data-driven approach helps businesses gain insights into how their teams communicate, what tools are most effective, and where improvements can be made. Advanced analytics tools provide metrics such as message response times, collaboration patterns, and sentiment analysis. This information can be used to optimize communication strategies, identify bottlenecks, and measure the impact of internal communication initiatives. It empowers organizations to continually make data-driven decisions to enhance their internal communication practices.
Mobile Apps for Internal Communication
The widespread use of smartphones has paved the way for mobile apps designed specifically for internal communication. Many organizations have developed their apps or use dedicated platforms like Microsoft Kaizala and Slack to engage with employees on the go. These apps enable employees to receive important notifications, access company resources, and participate in discussions from their mobile devices. They are precious for remote workers and employees who are frequently on the move. Mobile apps also support features like push notifications, ensuring critical information promptly reaches employees.
To Wrap Up
Technology has ushered in a new era of internal communication within businesses. Real-time collaboration tools, cloud-based document sharing, email transformations, AI-powered chatbots, video communication, social intranet platforms, and data analytics are pivotal in reshaping how teams interact and collaborate. As businesses adapt to the changing landscape, staying up-to-date with the latest technological advancements will be essential to maintaining effective internal communication and fostering a productive, connected workforce.

On the new Macbook Pros the issue of Bluetooth interfering with WiFi network is really bad. So bad that I could not use my bluetooth mouse while surfing the internet!
The issue is caused by the fact that both bluetooth and most WiFi network use frequencies near 2.4Ghz; signals are then overlapping and disturbing each other. So, some slight interference, is normal and maybe it’s more serious on the rMBP because it has a single card to handle both WiFi and BT.
The solution consists in setting priorities between WiFi and bluetooth (giving WiFi signal an higher one).
You have to launch the Terminal (Applications>Utilities>Terminal), paste the following code, press Enter and insert your admin password.
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid
The problem, in facts, is not solved. It can’t be solved, if radio signals are using the same frequencies. But, at least, I am able to use the internet with my mouse (that’s a pretty basic task :D)
The real solution would be to use different frequencies for the WiFi network: to avoid this kind of issues, WiFi is also available in 5Ghz frequencies, however just a few routers support that.
If yours do, all you have to do it to enable it in the settings page.
Please note that 5Ghz WiFi has a shorter range since higher frequencies can’t pass through objects and walls like lower ones do. Some routers even support both frequencies, so your devices can use the 5Ghz when in range, and 2.4Ghz otherwise.
However, if you don’t want to upgrade your router, the command I wrote about earlier is a great trade-off!

As a professional drone service provider, Autel Robotics' launch of enterprise drones has affected the entire drone market and brought huge competition. In the list of commercial drones, Autel Robotics has a total of five drones, namely Autel EVO II Dual 640t, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise .
Don't know enough? We will explain from the following angles.
1. Both have a foldable design and the color is orange.
- The propeller blades used by the EVO II enterprise will be longer and can replace the propeller blades of the EVO II RTK series, but it will affect the battery life.
- EVO II RTK series drones cannot use the propeller blades of EVO II enterprises, which will affect the motor load and cause safety accidents.
The EVO II RTK series supports 36 minutes of flight in a windless environment, and the EVO II Enterprise RTK also has a battery life of 36 minutes in a windless environment, but the EVO II Enterprise can carry different loads. Therefore, the flight time can reach 42 minutes with no load, 38 minutes with night lights, 29 minutes with searchlights, and 34 minutes with megaphones.
Both the EVO II RTK series and the EVO II Enterprise series include two drones, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise. EVO II Pro carries 6k Camera, the EVO II Dual 640T carries an 8k camera and thermal imager.
Image Transmission Performance
The EVO II RTK series supports 9 kilometers of image transmission, and the EVO II enterprise series supports up to 13 kilometers of image transmission.
RTK Module Difference
Both the EVO II RTK series and the EVO II Enterprise RTK use the same RTK module to achieve centimeter-level precise positioning with the same positioning accuracy. At the same time, the two also support network RTK, support PPK, and include microsecond time synchronization.
The EVO II RTK series is no different from the EVO II enterprise RTK connection. It needs to be connected through the APP. The remote control obtains the real-time differential data of RTCM3.0/RTCM3.1/RTCM3.2 through the local map transmission connection or 4G network.
RTK Base Station Mode
The EVO II RTK series uses the same base station model as the EVO II Enterprise RTK.
There are three supported RTK base station modes:
- Support remote control to connect to local RTK base station (A-RTK high precision positioning system) ( RTCM 2.X/3.X );
- Support the remote control to connect to the default network RTK service (RTCM3.2) through the 4G network; (free for the first year in China, and purchase for the second year);
- Support custom network RTK service based on N-Trip account connection (RTCM3.0/RTCM3.1/RTCM3.2)
Both EVO II RTK series and EVO II Enterprise RTK use the same RTK module, so the format of the file record is the same, with the following file formats:
- EVENTLOG.bin is the exposure timestamp log file in binary format;
- PPKRAW.bin is the mobile terminal satellite observation data and ephemeris data in RTCM3.2 MSM5 format;
- Rinex.obs is the transcoded Rinex observation file;
- Timestamps.MRK is the clear exposure timestamp in ASCII format, the location result of each photo at the time of taking the photo, the location status at the time of taking the photo, the standard deviation of the location, and the record file such as the time of taking the photo.

Traffic flows across a network in two directions - inbound and outbound. Proper filtering of this traffic ensures that a network is functioning as intended in a secure and efficient manner.
Inbound, or Ingress filtering, protects a network from invalid traffic originating from outside the network by blocking this traffic when it enters the network.
Outbound, or Egress filtering, ensures that your network does not transmit invalid traffic to remote networks.
Proper filtering can reduce the ability for a remote attacker to easily use spoofed packets and Man-in-the-Middle attacks across the network edge by disallowing traffic that meets certain specifications.
As an example, an attacker will often attempt to spoof a trusted host on the target network in order to abuse a trust relationship between two machines on your network. With proper Ingress filtering, the remote attacker's packets will never reach their intended target as the spoofed network address should never attempt to connect to the target machine from an outside interface.
Alternatively, the well-known and abused "un-routable" network spaces reserved for private use can be used to circumvent certain firewall implementations for the purpose of information retrieval and network mapping, and as a precaution, should be filtered on all edge routers.
These abused address spaces are generally called Bogons, and are defined as Martian blocks [Private (reserved for non-Internet usage) and reserved address spaces (multicast, experimental, future use) RFCs 1918, 3330] and blocks that are not currently assigned to a designated registry organization. Bogons should be filtered on both the inbound and outbound directions on all network interfaces that are open to the Internet. In reality, these Bogons should be filtered in all network devices regardless of their location or function, as such filtering when applied on a widespread scale will reduce the total amount of abusive Internet traffic.
It is important to note that the Bogon list is dynamic, and regularly changes as new block spaces are assigned and released, so regular updates will be required for comprehensive coverage. Publicly available Bogon lists are by no means a complete filtering solution, but are a great place to begin when identifying troublesome address spaces during the creation and deployment of any filtering solution. More information on the Bogon list can be found at the Team Cymru Bogon Reference at http://www.team-cymru.org/Services/Bogons.

Connection problems with Intel Centrino Advanced-N 6230 and Linksys WRT54G router
Using my new Dell XPS 15 (LX502) with an Intel Centrino Advanced-N 6230 wireless card I couldn't connect to my WRT54G router running the Tomato firmware anymore. Neither WPA nor WPA2 worked, not even WEP. Turns out that I had "Afterburner" mode enabled, which seems to cause problems, as also described here. After disabling this feature in the Tomato interface, everything worked nicely again.

Coaxial cable assemblies are an ideal solution for transmitting RF signals from one connection to the next within a system. They are most often used to connect a Printed Circuit Board (PCBs) to other PCBs but can also be used for I/O connections and to connect external antennas to wireless modules. Assemblies can vary in length from 0.98 inches (25 mm) to 1200 inches (100 feet) with various configurations (female (jack) to female, male (plug) to male, female to male, male to female), orientation (straight, right-angle) and mounting (bulkhead) options. These attributes, along with unique design features, allow standard assemblies to meet the specific design requirements of various applications across markets.
Our line of high-performance precision test cables (ATC-PS) feature additional phase stable and low loss capabilities which makes them ideal for test and measurement laboratory usage. Custom cable assemblies are available and offer a more tailored solution than standard products.

Please ensure you read the full disclaimer before proceeding . By proceeding you confirm you have read and agree to these terms.
PLEASE READ BEFORE CONTINUING:
If you are a home user; Reconsider using Cisco as a manufacturer for your router. I cannot recommend Cisco at this time If you’re buying a second hand router. This is due to the new requirement for Cisco Smart licensing which makes it almost impossible to get the correct licenses and support applied to your router if you purchased it second hand.
This is the configuration only guide for configuring a Cisco C1100 series ISR for BT Ultrafast 2 Broadband including IPv6 and BT TV / Youview. The purpose of this post is to list the commands required to configure the device to be used as a reference. The full guide with the commands explained can be found here.
For reference VLAN 1 represents any internal VLANs you have and VLAN 2 represents the Youview IPTV VLAN. Interface GigabitEthernet0/1/0 represents where the Youview box is patched. This is not a complete list of commands required to configure the device; Just the relevant commands.

You will also need to physically bridge the following interfaces with a dumb switch that won’t interfere with the traffic flow:
1 The BT ONT 2 The WAN port of the ISR (Gi0/0/0 above) 3 The LAN port for the IPTV VLAN (Gi0/1/0 above) 4 The Youview IPTV box
I can confirm that a Netgear GS305 works for this purpose.

Bevan Slattery is recognised as one of Australia’s leading entrepreneurs having founded some of Australia’s most successful technology companies.
In 2002, Slattery co-founded PIPE Networks which grew to become Australia’s largest Internet Exchange and Australia’s third-largest metropolitan fibre network provider – with over 1,500km of fibre in five cities connecting 80 data centres, 250 Telstra exchanges, and over 1000 buildings. In 2008, PIPE Networks proceeded with the construction of the $200m Sydney to Guam cable (PPC-1) with the project being completed in October 2009. PIPE Networks was sold to TPG for an enterprise value of $420m in May 2010.
In 2010, Slattery founded NEXTDC Limited (ASX: NXT), with a vision to become Australia’s largest independent data center provider. Having raised over $200m, NEXTDC launched data centres in Brisbane, Canberra, Melbourne, and Sydney, and began works in Perth, making NEXTDC Australia’s largest data centre provider in terms of geography and IT power capability.
In 2013, Slattery established Megaport (ASX: MP1) as the world’s first SDN-based elastic interconnection platform designed to provide a secure, seamless, and on-demand way for enterprises, networks, and services to interconnect. Bevan successfully launched Megaport in Australia, New Zealand, Singapore, and Hong Kong before the business was acquired by Megaport Limited in August 2015. Bevan oversaw Megaport’s listing on the ASX in December 2015.
Also in 2013, Slattery founded Superloop Limited (ASX: SLC) with a vision to become the leading independent provider of connectivity services across the Asia Pacific region and the US. Superloop was listed on the ASX in July 2015.
In addition to these success stories, Slattery founded Biopixel, Australia’s leading production service provider for natural history and animal behavioural sequences with a focus on aquatic life; Cloudscene, the world’s largest platform for searching cloud and connectivity services; SubPartners, a submarine cable operator and Indigo Cable investor; and SUB.CO, an Independent specialist submarine cable development group constructing the new Oman Australia Cable (OAC).
Bevan’s entrepreneurial success is highlighted in having listed a record five companies on the Australian Stock Exchange and receiving a multitude of industry awards including the EY Champion of Entrepreneurship Award in 2016, the Charles Todd Medal, and the Pearcy Foundation’s Benson Entrepreneur Award as well as being inducted into the Commsday and the ARN Hall of Fames.
Significant previous businesses that Bevan has founded include:
- Asia Pacific Data Centre Trust (ASX: AJD), an ASX‐listed REIT listed in December 2012;
- NEXTDC Limited (ASX: NXT), an ASX‐listed leading provider of data center services founded in 2010;

SPORTSAFE UK – IRIS
SportsafeUK supply, install and service sports equipment nationally. Their on-site services are conducted by over 40 engineers, who used an Excel-based system and emailed daily service reports. This slow, inconsistent process was inaccurate, costly and impacting other business functions.
ECS designed and implemented IRIS; a bespoke, fully integrated software solution, running on tablets. IRIS communicates seamlessly with two internal systems and enables managers to monitor and control the work, with completed reports automatically distributed.
ECS’s approach in standardising the process reduced the time taken to complete a service report from over 2 days to within 2 hours. It is now far simpler to train new engineers; paper records have been significantly reduced and SportsafeUK have made dramatic savings. The IRIS system has improved their customer experience and the entire business process has become more efficient – with quicker quote generation and faster follow-up on sales leads.
What they said
I have had the pleasure of working with the ECS Team throughout the development of IRIS. At over 25,000 visits per year across the whole country…the way the tablet creates the report for the customer to see whilst our team is still on-site has received great feedback from our 120 councils in the UK.
Our internal processes have sped up to a point where customers receive their quote and report the same day as the inspection…the report feedback direct from the customers is very positive.
The company is now looking at IRIS V2; this will take the system further forward and increase productivity across the business.”

Traffic Signal Coordination
The City of Peoria attempts to coordinate the traffic signals to provide safe and efficient traffic flow throughout the City. The ability to provide good coordination on a corridor is generally a function of signal spacing, prevailing traffic speed, amount of traffic, roadway capacity, signal cycle lengths, and conflicts with other major roadways. Not only does traffic signal coordination serve the greater good of the traveling public, but also has the added benefit of reducing fuel consumption and emissions because it reduces overall traffic delays.
In addition, except for in the Central Business District, most Peoria traffic signals use video or pavement loop detection systems to actuate the signal timing. This allows the signal to adjust the length of a phase of traffic, such as a left turn, to accommodate the current traffic load. This type of system helps clear the intersection and reduce the overall traffic delay. Another benefit of actuated signals is that they allow the controller to know when a vehicle from the side street approaches the intersection, which is particularly important at night because it allows the signals to maintain green signals on the main road and only call for the side street green to be activated when needed.
A majority of the signals in Peoria are coordinated, however, some are not. Signals that are in isolated locations or in too tight of a network do not lend themselves to good coordination. These intersections are often run in a free mode and change on the demand of traffic volumes. In the downtown area, where the streets are laid out in a grid fashion, it has been found that the signals run more efficiently pre-timed with short cycle lengths. The downtown intersections are still coordinated on some of the streets that have good progression, however, on other downtown streets, that do not have good progression because of the close proximity of the intersections, they are not coordinated.

In the second quarter China took over the position once held by the US as the world’s top smartphone market, with 33.1 million handsets in shipments, more than the 25 million handsets shipped in the US.
Since the start of the second quarter China’s smartphone shipments have passed those of conventional mobile phones. In June smartphones accounted for 56.9% of China’s mobile phone market.
The explosive growth is attributed to the introduction of budget-priced smartphones made possible by a sharp drop in hardware costs. Smartphones priced below 1,000 yuan ($157) cost less than 400 yuan ($63) to produce, according to Southern Daily.
Budget smartphones flooded the market during the first half of this year after China Unicom introduced them in the second half of last year, prompting China Mobile and China Telecom follow suit.
China’s smartphone shipments in the first quarter skyrocketed 164% over the same period of last year to 33.1 million handsets, according to data from the US-based asset-management firm Needham & Company.

We had so much fun creating interactive content for the last Data Digest that we decided to do it again. Today we present an interactive map showing broadband internet availability in the Coachella Valley. CVEP has long championed high-speed internet availability as a crucial component of attracting and retaining businesses in the valley. Remote-work households considering relocating to our valley look for high-speed internet when contemplating a move. While broadband access has improved, we have a long way to go. Click here to explore the map.
Our interactive map utilizes layers produced by Esri that compute a broadband score based on Federal Communications Commission (FCC) Form 477 data. The FCC requires “all facilities-based broadband providers to file data with the FCC twice a year (Form 477) on where they offer Internet access service at speeds exceeding 200 kbps (0.20 megabits per second) in at least one direction. Fixed providers file lists of census blocks in which they can or do offer service to at least one location.” You can zoom into this map to get this census block level data.
The FCC’s minimum standard for broadband of 25 Mbps download and 3 Mbps upload sets the broadband score at 100. That score is then weighted by the population in the area, the population served by different speeds, and breakdowns of race/ethnicity. The map layers have been color-coded to show speeds above and below this FCC standard of 100. Red/orange areas are below the standard, and green areas are above. These data are updated twice yearly, but the FCC takes a while to compile them. The most recent data in these maps is for June 2021.
Because the score is calculated in real-time based on the user’s selection, we have filtered the data just for Riverside County, for performance issues. This map shows Western Riverside County east to the Coachella Valley. At this scale, we are seeing Census tract data. Note how Western Riverside County has much more contiguous high-speed access in the aggregate, while the Coachella Valley has much less. Be aware that at the Census tract level, the broadband scores are computed for a much larger area. If we zoom in, the scores become more nuanced. Still, at this scale, only five census tracts in the Coachella Valley have aggregated broadband scores above the FCC standard.
We see the most granularity at the Census Block level. This is the geographic level for which the FCC requires data for Form 477. For each geographic level, a pop-up block of text details the characteristics of broadband access for the chosen block.

Jeremy Naydler, Wake Up World
In November last year (2018), the United States Federal Communications Commission (FCC) authorized the rocket company SpaceX, owned by the entrepreneur Elon Musk, to launch a fleet of 7,518 satellites to complete SpaceX’s ambitious scheme to provide global satellite broadband services to every corner of the Earth. The satellites will operate at a height of approximately 210 miles, and irradiate the Earth with extremely high frequencies between 37.5 GHz and 42 GHz. This fleet will be in addition to a smaller SpaceX fleet of 4,425 satellites, already authorized earlier last year by the FCC, which will orbit the Earth at a height of approximately 750 miles and is set to bathe us in frequencies between 12 GHz and 30 GHz. The grand total of SpaceX satellites is thus projected to reach just under 12,000.
There are at present approximately 2,000 fully functioning satellites orbiting the Earth. Some beam down commercial GPS (or ‘SatNav’), some provide TV, some provide mobile phone services, and some bounce radar back and forth to produce images for meteorologists and military surveillance. The Earth is thus already comprehensively irradiated from outer space. But the new SpaceX fleets will constitute a massive increase in the number of satellites in the skies above us, and a correspondingly massive increase in the radiation reaching the Earth from them. The SpaceX satellite fleet is, however, just one of several that are due to be launched in the next few years, all serving the same purpose of providing global broadband services. Other companies, including Boeing, One Web and Spire Global are each launching their own smaller fleets, bringing the total number of projected new broadband satellites to around 20,000 – every one of them dedicated to irradiating the Earth at similar frequencies.
Why this sudden flurry of activity? The new satellite fleets are contributing to a concerted global effort to ‘upgrade’ the electromagnetic environment of the Earth. The upgrade is commonly referred to as 5G, or fifth generation wireless network. It has become customary in tech circles to talk about the introduction of 5G as involving the creation of a new global “electronic ecosystem.” It amounts to geo-engineering on a scale never before attempted. While this is being sold to the public as an enhancement of the quality of video streaming for media and entertainment, what is really driving it is the creation of the conditions within which electronic or “artificial” intelligence will be able to assume an ever-greater presence in our lives.
The introduction of 5G will also require hundreds of thousands of new mini mobile phone masts (also referred to as “micro-cells” or “base stations”) in urban centres throughout Australia, and literally millions of new masts in cities throughout the rest of the world, all emitting radiation at frequencies and at power levels far higher than those to which we are presently subjected. These new masts are much smaller than the masts we currently see beside highways and on top of buildings. They will be discreetly attached to the side of shops and offices or secured to lampposts. The 20,000 satellites are a necessary supplement to this land-based effort, for they will guarantee that rural areas, lakes, mountains, forests, oceans and wildernesses, where there are neither buildings nor lampposts, will all be incorporated into the new electronic infrastructure. Not one inch of the globe will be free of radiation.
Given the scale of the project, it is surprising how few people are aware of the enormity of what is now just beginning to unfold all around us. Very few people have even heard about the 20,000 new satellites that are due to transform the planet into a so-called “smart planet,” irradiating us night and day. In the national media, we do not hear voices questioning the wisdom, let alone the ethics, of geo-engineering a new global electromagnetic environment. Instead, there is a blithe acceptance that technology must continue to progress, and the presence in our lives of increasingly “smart” machines and gadgets that each year become cleverer and more capable is an inevitable part of this progress. And who doesn’t want progress? Almost everyone loves their sleek and seductively designed phones, iPads and virtual assistants, and regards them as an indispensable part of their lives.
The question we should ask is whether we also want increasingly intense exposure of the natural environment and all living creatures, including ourselves, to more and more electromagnetic radiation. Is it likely that this does not entail any adverse health consequences, as both government and industry claim? If the electromagnetic waves that connect our smartphones to the Internet travel through brick, stone and cement, then what happens when these same waves encounter our bodies? Be assured that they do not just bounce off us! They travel into the human body. The degree to which they are absorbed can be precisely measured in what is called the Specific Absorption Rate, expressed in Watts per kilogram of biological tissue. When we fill our houses with WiFi, we are irradiating our bodies continuously. When we hold a smartphone to our ear, electromagnetic waves irradiate our brains. Do we really believe this could be completely harmless?
Waves and Frequencies
At present, mobile phones, smartphones, tablets, WiFi and so on all operate at under 3 GHz in what is called the “microwave” region of the electromagnetic spectrum. If you could see and measure their wavelengths, you would find that they are many centimeters (or inches) long. A smartphone operating at 800 MHz, for example, sends and receives signals with wavelengths of 37.5 centimeters (just under 15 inches). Operating at 1.9 GHz, the wavelengths are 16 centimeters (just over 6 inches). WiFi uses the 2.4 GHz frequency band with 12 centimeter wavelengths (just under 5 inches long).
The introduction of 5G will entail the use of considerably higher frequencies than these, with correspondingly shorter wavelengths. Above 30 GHz, wavelengths are just millimeters rather than centimeters long. The millimeter waveband (from 30 GHz to 300 GHz) is referred to as Extremely High Frequency, and its wavelengths are between 10 millimeters and 1 millimeter in length.3 Up to the present time, Extremely High Frequency electromagnetic radiation has not been widely propagated, and its introduction marks a significant step change in the kind of electromagnetic energy that will become present in the natural environment.
The reason why millimeter waves are to be used for 5G is that much larger bands of spectrum are available in the Extremely High Frequencies than at lower frequencies. This means that there can be much broader “bandwidth.” Broader bandwidth means that larger quantities of data can be transferred and the speed of transfer of the data will be significantly faster. One of the effects of this is that it reduces what is called “latency,” or time-lag, in the system, improving the quality of video streaming. But in so doing, it also enables a greater seamlessness between the data accessible from virtual sources and our perceptions of objects in the real world, as is required, for example, in Augmented Reality applications. Greater seamlessness means that we more effortlessly inhabit the natural and the electronic worlds as if they were a single reality.
One of the technical problems of using frequencies in the millimeter region of the spectrum is that because the waves carrying the data are so tiny, being only millimeters long, they are less able to pass through physical barriers, like walls and trees, than are the longer waves of lower frequencies. This is why it is necessary to have so many more new “micro-cells” or “base stations.” They will need to be spaced at 100 meters apart in cities because beyond this distance their signals weaken and are therefore less able to penetrate buildings and connect with the devices inside. As well as being more closely spaced, the 5G micro-cells will operate at much higher power than current phone masts in order to ensure that the signals are sufficiently strong.
Because the wavelengths are so much smaller, the antennas transmitting and receiving them will also be much smaller than those of current phone masts and electronic devices. A single 5G transmitter/receiver will have a large number of tiny antennas, grouped together in one unit. An array of just over a thousand such antennas measures only four square inches, so will easily fit into a small base station on a lamppost, while the smartphone in your pocket will probably have sixteen.
Both 5G satellites and 5G land-based masts will use a system called the “phased array.” In phased array, groups of antennas are coordinated to radiate pulses in a specific direction and in a specified time sequence. This allows a concentrated beam of radio waves to be exactly aimed at designated targets, to enable signals to be sent or received. Because the beams are concentrated in this way, this adds to their power, which means they are able more easily to penetrate buildings. But it also means that any living creature that gets in the way of such a concentrated beam will be subjected to a powerful dose of extremely high frequency radiant electricity.
A study published earlier this year demonstrated that certain insects, because of their small body-size, are particularly vulnerable to the millimeter waves of the higher frequencies to be utilized by 5G.5 Other studies have shown that bacteria and plants are vulnerable, and so also (as one might expect) are the skin and the eyes of animals including, of course, human beings.6
As well as its ability to concentrate power in focused beams, phased array technology has a further complicating factor. Either side of the main beam, the time intervals between the pulses are different from the time intervals between those of the main beam, but they may overlap each other in such a way as to produce extremely rapid changes in the electromagnetic field. This can have a particularly detrimental effect on living organisms, because instead of the radiation decaying when it is absorbed into living tissue, it can be re-radiated within the body. The moving charges streaming into the body effectively become antennas that re-radiate the electromagnetic field and send it deeper into the organism. These re-radiated waves are known as Brillouin precursors, named after the French physicist Leon Brillouin, who first described them in 1914. Research suggests that they can have a significant and highly detrimental impact on living cells.8

The government body charged with advising on the health effects of electromagnetic radiation, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), seeks to reassure us that there is no established evidence that Radio Frequency radiation (which radio, television, mobile phones, smartphones and 5G all use) has any adverse health effects on either adults or children.9 ARPANSA’s advice is largely based on findings derived from the supposedly independent AGNIR (Advisory Group on Non-Ionising Radiation), which advises the UK Health Department.10 AGNIR’s report, published in 2012, on the safety of Radio Frequency radiation stated that there was a lack of “convincing” and “conclusive” evidence for any adverse health effects. It was like giving a blank cheque to the telecommunications industry to move into the higher frequencies without any heed for the consequences.11

For å strømme film må du ha en hastighet på 5-6 Mbit/s (megabit per sekund) og om noen samtidig leser en nettavis, skyper eller strømmer musikk blir det ytterligere 1,5 Mbit/s Definition: A megabit per second (Mbps) is a unit of data-transfer rate. A megabit per second, not to be confused with megabyte per second, is equal to 1,000,000 bits per second, or 1000 2 bits per second. A megabyte per second (MBps) on the other hand is equal to 8,000,000 bits per second since each byte contain 8 bit
That's a speed between roughly 2 Mbps and 5 Mbps. For 720p video at 60 frames per second, the range is 2,250 to 6,000 kbps. Speed-wise, that's between 2.9 Mbps and 7.4 Mbps. For 1080p video at 30 frames per second, the bitrate range is 3,000 to 6,000 kbps. That translates into speeds between 3.8 Mbps and 7.4 Mbps To convert gbit/s to mbit/s you need to multiply the gbps number by 1,000. It is that simple, but still a converter like the one above is useful if you need to make the calculation many times, or you need to be sure that it is done in the same correct manner each time. A step by step calculation example is below. Gbps to Mbps conversion exampl For example, an internet speed test can measure your network's speed at 18.20 Mbps, which means that 18.20 megabits are being transferred every second. The same test can say that the available bandwidth is 2.275 MBps, or megabytes per second, and the values are equal. As another example, if a file you're downloading is 750 MB, it's also 6,000 Mb
The only way to answer this is to know exactly what type of streaming you're talking about. (We'll get into the differences between downlink/download-speed and uplink/upload-speed later.) 1. Streaming videos from the 'net to you. 2. Streaming vide.. This is sometimes written as kbps, Kb/sec or Kb/s but all of them carry the same meaning. One megabit per second equals 1000 Kbps or one million bps. It's also expressed as Mbps, Mb/sec, and Mb/s. One gigabit per second equals 1000 Mbps, one million Kbps or one billion bps. It's also abbreviated as Gbps, Gb/sec, and Gb/s

To give you an idea of how much speed can play a role in downloading and uploading, we've listed the estimated time it would take to download a two-hour HD movie and upload a 10-minute video with.
4-6 mbps: Will provide a good Web surfing experience. Often fast enough to stream a 720p high-definition video, and it's possible to download some videos within about 20 minutes at this speed. But. Even 2 Mbps is enough for high-quality full-screen video streaming. But the problem is not the rated speed advertised by your provider, it's the guaranteed speed. Your provider may give you 40 Mbps to servers nearby on a good day. But what will yo.. One mbps (megabit per second) is one eight of a byte. That is to say, it will take you 8 seconds to download a 100MB file at 100 Mbps. Here you only need consider your data transfer habits and you will be able to calculate your exact monthly requirements precisely The megabit is a multiple of the unit bit for digital information.The prefix mega (symbol M) is defined in the International System of Units (SI) as a multiplier of 10 6 (1 million), and therefore . 1 megabit = 10 6 bits = 1 000 000 bits = 1000 kilobits. The megabit has the unit symbol Mbit.. The megabit is closely related to the mebibit, a unit multiple derived from the binary prefix mebi.
Convert bitrate units Kbps, Mbps, Gbps for all network technologies, and much more Mbps: Stands for Megabits Per Second. One megabit is equal to one million bits or 1,000 kilobits. While megabit sounds similar to megabyte, a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte). Mbps is used to measure data transfer speeds of high bandwidth connections, such as Ethernet and cable. My internet speed is (theoretically) 200 Mbps when ethernet's plugged in, wireless is obviously less but I regularly check and it's about 70 Mbps off-peak hours and about 30-40 Mbps during peak hours (usually evening) which is when sometimes the image stutters or completely freezes when I stream 4K HDR movies. I am going to upgrade to 1 Gbps
I think the ISP's use the mbps in combination with the 1000 system to mislead uninformed consumers. It's all a sales gimmick, in my opinion. Furthermore, for those who still don't quite grasp it, I subscribe for a 10(mbit) line with Comcast, which equates to 10,240(kBytes) for binary value or 10000(kbits) on the 1000 system depending on ISP

Gubagoo’s Website Platform Now Optimized for Mobile
WEST PALM BEACH, Fla. — Gubagoo’s behavioral analytics-based chat and website engagement platform for dealer websites is now fully optimized for mobile, the company announced this week.
The new capability is designed to allow dealerships to track and then relevantly target — through chat, personalized offers and inventory display — every single visitor that hits their website via a smartphone or tablet.
With an estimated 30% to 40% of dealer site traffic now coming through mobile devices, Gubagoo is serving up the chats, offers and inventory to on-the-go mobile shoppers. The solution also keeps shoppers on the dealership’s mobile site rather than forcing consumer onto another page and breaking continuity, officials noted.
Free to current clients of the company, Gubagoo Mobile works on any native smartphone or tablet device, requires no app downloads and is able to automatically detect the presence of a mobile browser. It then instantly sets the mobile engine in motion.
“Very soon, mobile will overtake the desktop as the way most people access dealer sites,” said Brad Title, CEO of Gubagoo. “And if a dealer’s vendors don’t enable smarter chat and more relevant site communications on mobile, they’re throwing 30% to 40% of their traffic away.”

Staying in touch
Keep in touch with friends, family and colleagues while traveling abroad has become so much easier thanks to the internet and social networks.
Travelers logging onto social networks while abroad should ensure that they properly log out before leaving an internet café or similar because in some areas of Africa, East Europe and India it’s not unknown for a watcher to access a tourist’s Facebook (or similar) account after they leave and send a desperate message to family members about an accident/hospitalisation and needing money urgently. Money transferred of course disappears into a mystery account and no one’s the wiser, for the time being.
Best way to communicate while travelling (updated December 2015)
1. Using your own mobile/cell phone
– Check out your provider’s deals for using an extended service outside your registered country and check if your phone works over the network at your destination, as well as the cost.
Turn voicemail off as some companies charge for incoming calls. Also it’s best to switch off the cloud service, mobile data and roaming data as those apps can really rack up the charges. Use free local Wifi instead.
– If your trip is long or you use the phone a lot, the best way to save money is:
If your phone is unlocked, get a local sim card and buy prepaid credit, possibly with data too so that you can use 3G or 4G. The downside of a new sim card means the number will be also new.
If your phone is locked, either get it unlocked or buy a cheapo unlocked local phone.
2. Using VoIP (Voice over Internet Protocol) services such as Skype, Facebook Messenger, Google+Hangouts, WhatsApp, Viber, LINE and Tango with your devices.
This involves contact via the internet, though nowadays it’s not only speech or video calls but all sorts of communication ranging from instant messages and chats to sharing images and videos from anywhere worldwide free of charge, so long as each party has access to WiFi.
Although WhatsApp is only free for the first year – with cost of a dollar per year after that – WhatsApp is a brilliant service and currently the most popular app on the planet, with 900 million users worldwide.
LINE has 50 million registered users in Japan and nearly 600 million worldwide.
For a faster and more secure service, the newish Telagram is recommended. It’s a cloud-based messenger with seamless sync, ad free and costs nothing.
3. Sign up with a global WiFi internet service such as Boingo and Fon WiFi.
You pay a small fee per month (from US$4. 98 for the first months then $9. 95; a higher price for laptops) for access to WiFi hotspots such as airports, stations and cafés worldwide.
Alternatively Skype users can use Skype credit to connect to WiFi.
– For those who need to be connected to WiFi or data all the time, you can rent a portable WiFi-enabled device or a pocket WiFi. This is a wireless modem from companies such as XCom Global and Tep wireless that gives have access to high-speed Internet at a flat rate (from €8. 95/$9. 95/£6. 50 a day).
4. Not a cheap options but if your purpose is limited to emergencies, buy or rent a prepaid phone, online or at the airport on your arrival.
5. Old fashioned but check out the new generation phone cards to call just about anywhere, though public pay-phones are disappearing so it’s hard to find one that works properly when you need to make a call! Also others can’t to reach you, unless that is precisely your point!

Vivo aims to make 5G smartphones more convenient, accessible, and affordable. Some of the following phones are a testament to that dedication. We have Vivo phones from higher tiers like the Vivo X90 Pro 5G to the economical entries like the Vivo T2X 5G. Needless to say, these and the phones that come in between are different in their 5G capacity and in other terms too. So, we hope you get what you are looking for.
1. Vivo X90 Pro 5G
Vivo X90 Pro 5G is the Vivo flagship for H1 2023. As its name suggests, the phone brings 5G support. The MediaTek Dimensity 9200 chip at the core offers up to 7900 Mbps download speed and up to 4200 Mbps upload speed. You can get Android 13-based Funtouch OS after an update. The camera island at the back of the phone houses a 50.3MP main camera, a 50 MP telephoto and a 12 MP ultrawide sensor. The front camera is a 32 MP shooter. The Vivo X series is known for its camera chops and especially things like the Zeiss optics and filters. In the mix of features, there is a 4870mAh battery with 120W wired charging and a 120Hz FHD+ AMOLED display.

Go for this one if you want the best of the best Vivo has to offer in terms of performance and optics. 5G is just a given in such an illustrious assortment of specs.
2. Vivo V27
Vivo V27 is far cheaper than the above one but isn’t too weak in its offering. The 5G download speeds from the device can go up to 4700 Mbps thanks to the MediaTek Dimensity 7200 processor inside.

AWS provides a cost effective and resilient network platform that meets both Snapper’s expansion plans and strategic IT goals
The Amazon solution designed by Fronde has provided Snapper, New Zealand’s leading contactless payment system, with a flexible, low cost and robust network which will expand as needed to match Snapper’s nation-wide growth focus. The fast to deploy system has up to the minute disaster recovery and can be managed on multiple devices from anywhere in the country.
Snapper had been using a third party to interconnect the remote transport terminals with the central Snapper processing hub.
This single processing hub had several deficiencies:
- Reliance on a third party network
- Slow speed of new site deployment
- Lack of system flexibility for expansion plans
Fronde designed and deployed a new network using low cost commodity hardware to support Snapper’s expanding national payment system and integrated a Virtual Private Cloud (VPC) using Amazon Elastic Compute Cloud (Amazon EC2). This design also accounted for primary and disaster recovery processing hubs, with the ability to reroute all remote terminal traffic should the primary hub fail.
A secure virtual private network (VPN) connection between the processing hubs and the Amazon Virtual Private Cloud, allowed AWS Compute instances (Amazon EC2 servers) to connect securely and seamlessly to all parts of the Snapper network.
Amazon products used:
- Amazon Elastic Cloud Compute (EC2)
- Amazon Virtual Private Cloud (VPC)
- Amazon Simple Storage Service (S3)
- Amazon Identify and Access Management (IAM)
Norman Comerford, CTO at Snapper Services Ltd said,
"This initiative has delivered a secure, robust, flexible, fast and accessible path to Amazon’s infrastructure services, enabling us to prove the promise that innovation can be delivered at warp speed."

INVmate II – Problems handling
Conditions for the best operation of the WiFi module
- Ensure that you're aware of your WiFi network security key (WPA key)
- The modem/router should be working properly
- Ensure that there's a DHCP service (automatic TCP/IP addressing) on your network and it works properly.
- In case of a firewall existence on your network, please open the following ports: TCP/28870, UDP/53 (DNS)
How does the WiFi module installation procedure works;
Enable the "AP" mode on the air conditioning unit. By activating the AP mode, the unit acts as an Access Point. Create an INVmate account on which you can bind the air conditioning unit(s), so you can manage the unite remotely. Join the air conditioning unit to your home network to have access to the internet.
Can i use the WiFi module on another compatible air conditioning unit?
Yes, you can.
Can i manage the air conditioning unit through an additional mobile device (simultaneously)?
Yes, you can.
Can i manage the air conditioning unit through 2 different INVmate accounts?
Can i manage more than 1 air conditioning units through the same INVmate account?
Yes, you can.
What happens if i replace my mobile/tablet device, do i have to setup the air conditioning unit from the beginning?
No. You can install the INVmate application on your new mobile/tablet device and log in using your INVmate account.
Do i need a static internet ip?
No, the INVmate II application works with a dynamic internet IP as well.
When i press the "LED" button 7 times, the "AP" indicator doesn't show up on the front panel of the air conditioning device.
Ensure that you have NOT turn the air conditioning device on (from the on/off button of the remote controller)
During the installation procedure i get the “Connecting Hotspot failure” error message.
The network security key you have used, is wrong. Please ensure that you're using the right one.
I'm searching for the INVmate II application on the App Store from my iPad but it doesn't show any results.
At the top left corner of your ipad, select "iPhone Only” as in the example below:
I'm searching for the INVmate II application on the Play Store from my Android device, but it doesn't show any results.
Please type exactly the following text " INVmateii " in the search box.
I have lost the white QR Code sticker of the wifi module.
You may scan the QR code located on the surface of the Wifi module.
I can't operate the air conditioning device remotely, the status is Offline.
- Ensure that the air conditioning unit power cord, is connected to the power source.
- The air conditioning unit didn't get the command from the INVmate II application, please try again.
- Please move the modem/router closer to the air conditioning unit in case of wifi signal loss.
- The internet connection of your modem/router is down.
- Please disconnect the power of the air conditioning unit and reconnect again.
When i scan the QR Code i get the following error message: “QR Code is illegal!”.
Ensure that you're scanning the right QR code sticker (the white one located in the wifi module box).
When i scan the QR Code it doesn't show any progress.
The air conditioning unit is not in a "AP" condition. Unplug the unit's power cord, wait for 10 seconds, reconnect it and press the "LED" button 7 times repeatedly till the "AP" indication blinks. Then start the installation process again from the beginning.
I forgot my password
In the initial screen of the INVmate II application select (right down) “Forgot Password?” and then select “Send retrieve password email”
I haven't received the confirmation mail for the "create my account".
- In the initial screen of the INVmate II application select (right down) “Forgot Password?” and then select “Resend Activation email”
- Control whether you have received the mail as a junk (SPAM).
My Android device is not compatible with the INVmate II application.
In that case you have to install the application manually.
- Download the installation file by clicking here
- Save the file on your mobile
- Install it (maybe you should change first the security setting of your mobile in order to enable the installation of applications coming from unknown sources)
