  • Patent number: 5586120
    Abstract: A radio communication system (100) operates according to a channel hopping protocol on communication channels grouped into channel blocks, including a channel block of reservation channels, from which channel hopping sequences are organized (810, 820). Each sequence has a communication channel from each channel block, including a reservation channel from the channel block of reservation channels (820). A first transceiver selects multiple sequences for operation (840, 842). The transceiver reserves a communication slot on each sequence such that corresponding communication slots exist on a group of channels simultaneously across the sequences (842, 844). The transceiver then operates within the communication slots on successive communication channels of the sequences according to the channel hopping protocol (846). A second transceiver may select a subset of the sequences of the first transceiver for its operation (860, 862, 864, 866).
