This repository releases a dataset of 80 WiFi bandwidth traces collected in November 2023 in Beijing, China. Please feel free to use these traces.
We used iPerf v3.1.3 to measure and record the WiFi link bandwidth. The client and server are located in Beijing and running Ubuntu 18.04. The server command is: iperf3 -s -p [SERVER_PORT] -D, and the client command is: iperf3 -c [SERVER_IP] -p [SERVER_PORT] -i 1 -d 200. The client runs Python scripts to perform each measurement (see scripts/).
All traces (traces/) are collected in static indoor environments, including 4 locations: cafe, campus, office, and restaurant. Each trace lasts 200 seconds, with a granularity of 1 second. Detailed information is shown in the following table and figure (here, the bandwidth indicates the average value of each trace):
| Location | WiFi Information | Trace Count | Bandwidth Range (Mbps) | Avg. (Mbps) | Std. (Mbps) |
|---|---|---|---|---|---|
| cafe | 5GHz WiFi 4 (802.11n) | 20 | 7.448~7.867 | 7.812 | 0.099 |
| campus | 5GHz WiFi 5 (802.11ac) | 20 | 36.709~73.165 | 63.750 | 9.754 |
| office | 5GHz WiFi 5 (802.11ac) | 20 | 7.282~29.124 | 15.532 | 6.334 |
| restaurant | 5GHz WiFi 6 (802.11ax) | 20 | 9.362~9.807 | 9.567 | 0.133 |
