WiFi performance test · July 6, 2026
Test method: an 88 MB file was transferred both ways between a PC and the device over WiFi using SCP, and the average speed reported by scp was recorded. Upload = PC → device, download = device → PC.
With the signal improved from -62 dBm to -47 dBm, upload speed rose from 2.9 to 5.3 MB/s and download from 2.6 to 5.2 MB/s — roughly 1.8–2.0× faster.
| Signal strength | Direction | Avg speed | Equivalent bandwidth | Time | File size |
|---|---|---|---|---|---|
| -62 dBm | Upload | 2.9 MB/s | ≈ 23.2 Mbps | 30 s | 88 MB |
| -62 dBm | Download | 2.6 MB/s | ≈ 20.8 Mbps | 34 s | 88 MB |
| -47 dBm | Upload | 5.3 MB/s | ≈ 42.4 Mbps | 16 s | 88 MB |
| -47 dBm | Download | 5.2 MB/s | ≈ 41.6 Mbps | 16 s | 88 MB |
Note: speeds are application-layer averages measured by SCP (including SSH encryption and protocol overhead); bandwidth converted at 1 MB/s = 8 Mbps. Signal strength is the RSSI measured at the device.
