Yes, the interference can be calculated by averaging the beacon RSSI (dB)
of the overlapping channels, e.g. for channel 6, the beacon RSSI of
channels 4, 5, 6, 7, 8 are averaged. Normally channels 1, 6, and 11 are
chosen, although other channels may have less interference, in order to be
a 'good neighbor'.
