Abstract
A method of dynamic channel allocation in a frequency hopping communications system is disclosed providing improved efficiency and reliability. During the course of communications between a plurality of transceivers over a frequency hopping wireless communications link, a transceiver begins evaluating the performance of each channel in the hop sequence, starting at a fixed point in the sequence. The transceiver proceeds sequentially through the hop sequence, until a channel fails to satisfy a predetermined quality criterion. A channel which fails to satisfy the quality criterion is considered bad, and substituted with a replacement channel from a set of available channels via an unacknowledged channel replacement command. The channel evaluation process is subsequently reinitiated beginning anew at the fixed point in the hop sequence, thus operating to maintain a set of consecutive good channels.
