Abstract: A ‘smart’ sub-channel hopping control mechanism executes one or more sub-channel selection discriminators to enable the communications controller of a spectral reuse transceiver to delineate on which of a plurality sub-channels the spectral reuse transceiver may transmit, so as to substantially improve FEC performance.
Abstract: A method of allocation transmission channels of a frequency band to has each of a plurality of remote stations monitor all channels of the frequency band in its area for the presence of transmissions from stations not part of the network. Each remote station transmits its clear channel list to a master station that aggregates the clear channel list into a reservation map, or map of channels that are clear to all stations in the network. The master station then transmits the reservation map to all stations of the network. The individual stations use the channels of the reservation map to transmit information to the master station. Preferably transmission is accomplished using frequency hopping using a set of channels selected from the reservation map.
