**Description:** A finer-level sequential dataset of WiFi received signal strengths (RSS).
|
| 16 |
+
The dataset contains 290 trajectories collected across 3 floors of C4 building of Nazarbayev University.
|
| 17 |
+
The RSS values with corresponding position coordinates (x,y,z) are recorded around every 5 seconds.
