ABSTRACT:
The process of the present invention is based on a hexagonal cellular platform where six, or a multiple of six, frequency groups are directionalized and reused in the same direction. Directional antennas are located in the center of each cell. Each antenna radiates into a 60.degree. sector of the cell. The reused frequency groups are aligned along the 0.degree., 120.degree., and 240.degree. axes of each cell. Each axis has three layers, the two outer layers having an identical frequency reuse series. The frequency groups are reused in the same direction along each axis, reducing the number of dominant interfering cells to one.
