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.
A method for selecting a plurality of channels over which at least a first wireless transceiver and a second wireless transceiver communicate, in which at least the first transceiver measures the quality of communications on each channel of the plurality of channels on which it communicates, which method comprises the following steps performed repeatedly:
A method for communicating digital data over a wireless communications link via packets transmitted sequentially over a plurality of frequency channels, said packets comprised of at least potentially varying proportions of primary data content and/or secondary control data, which method comprises:
