# WiFine
**Paper:** [Finer-level Sequential WiFi-based Indoor Localization](https://ieeexplore.ieee.org/abstract/document/9382623)

**GitHub:** [https://github.com/IS2AI/WiFine](https://github.com/IS2AI/WiFine)

**Description:** A finer-level sequential dataset of WiFi received signal strengths (RSS).
The dataset contains 290 trajectories collected across 3 floors of C4 building of Nazarbayev University.
The RSS values with corresponding position coordinates (x,y,z) are recorded around every 5 seconds.
