Performance Table (20MHz Bandwidth)
| Distance | Max UDP Throughput (Mbps) | Sensitivity (Single/Dual Antenna) |
|---|---|---|
| 10 km | up to 47 Mbps | -101 / -104 dBm |
| 50 km | up to 40 Mbps | -95 / -98 dBm |
| 100 km | up to 34 Mbps | -92 / -95 dBm |
| 200 km | up to 26 Mbps | -88 / -91 dBm |
| 300 km | up to 21 Mbps | -83 / -86 dBm |
