A system of allocating cellular frequencies (channels) to the sectors among the outer tier of cells within a tile is disclosed which maximizes channel set usage within the tile while minimizing co-channel interference between cells. Any unused, or remaining, frequencies for the outer tier of that cell may then be allocated to an inner tier of the cell that has not had a channel allocated thereto. No additional infrastructure or maintenance set-up is required under this technique for allocating the channel to the additional transceiver and a very high degree of channel utilization is achieved.
