Smaller bandwidths provide more channels to choose and help avoid interference issues. The system’s SNR is higher at smaller Channel Bandwidths and Range is longer. Antenna Signal Strength -35 to -85 dBm (Recommended), Absolute Maximum=+12 dBm Receiver LNA Gain >10 dB Receive chain Noise Figure 6 dB RF Power control by Driver In 0.5 dBm steps. Accuracy of power calibration loop ±2 dBm. Each transceiver individually calibrated and tested. RF Hardware Disable (RF Kill) Pin 20 of miniPCI-E interface.
