A cellular FH/MFSK spread-spectrum mobile network with a total bandwidth in each cell of 2*W/sub ss/ is considered. There are two nonoverlapping channels within each cell, uplink and downlink, each with a bandwidth of W/sub ss/. The uplink channel handles information from the mobile units to the cell base station and the downlink channel directs information from the cell base station to the mobile users. To avoid any interference from adjacent cells, each of the neighboring cells has a different center frequency for the uplink and downlink channels than for the adjacent cells. It is considered that the number of cells with different center frequencies in a cellular network is C. To enhance the frequency efficiency, the same group of frequencies is reused at a different geological distance away from each other.
