Abstract:
1. A method for determining a Master-Slave frequency hopping sequence, the method comprising the steps of: during a frequency hopping sequence, scanning a plurality of frequency channels; measuring signal characteristics associated with each scanned channel, including monitoring whether data on a scanned channel has been requested by the Slave to be retransmitted by the Master; comparing the measured signal characteristics with predetermined signal characteristics to determine whether a channel demonstrates insufficient signal characteristics and further to determine which channels demonstrate acceptable signal characteristics; and without changing transmitted signal characteristics, causing communication between the Master and at least one Slave to dwell on a selected channel frequency for a predetermined period of time associated with a plurality of data packets, the selected channel frequency associated with a channel demonstrating acceptable signal characteristics, the dwell frequency displacing a channel frequency associated with a channel demonstrating insufficient signal characteristics; and After said predetermined period of time, resuming said frequency hopping sequence.
