WIRELESS INTERFERENCE SCANNING METHOD AND DEVICE FOR ADAPTIVE FREQUENCY HOPPING

摘要

The present disclosure provides a wireless interference scanning method and device for adaptive frequency hopping. The wireless interference scanning method comprise detecting the overall signal magnitude over a wide-band; determining whether the overall signal magnitude over the wide-band is larger than a threshold; sequentially detecting a plurality of channels in the wide-band to determine whether there is an interference signal in the channels when the overall signal magnitude over the wide-band is larger than the threshold; and redetecting the overall signal magnitude over the wide-band for determining whether the overall signal magnitude over the wide-band is larger than the threshold when the overall signal magnitude over the wide-band is not larger than the threshold.
