System and method for wireless frequency hopping network

Abstract

A method (10) for determining a frequency hopping sequence for a newly-entering network. The method comprises the step of scanning (16) a plurality of frequency channels. For each of the plurality of frequency channels, the scanning step comprises detecting whether a signal (18,22) exists on the channel and recording information (20,24) corresponding to each channel on which a signal is detected. Finally, and responsive to the recorded information, the method forms (30) the frequency hopping sequence.
