Abstract
A cellular system, in which frequency channels are allocated among transceivers which transmit to sectors of a cell, in which adjacent frequencies do not appear in adjacent sectors within the cell. A series of consecutive frequency channels is allocated to these transceivers, sequentially and alternately between opposing pairs of vertical sectors. Allocation is started from a first pair, and continued, each time, to the next pair which is adjacent to its preceding pair in clockwise or counterclockwise direction. Optionally, at least one frequency channel from the series of frequency channels is skipped, each time before continuing to allocate frequency channels to the next pair. By doing so, adjacent frequency channels are not allocated to adjacent sectors, and adjacent frequency channels do not appear in adjacent sectors even after moving allocated frequency channels from a sector to each of its adjacent sectors.
