Abstract
The process of the present invention is based on a tri-cellular platform where nine, or a multiple of nine, frequency groups are directionalized and reused in the same direction. Directional antennas are located in the center of the tri-cell group. Each antenna radiates into a 120.degree. sector of each cell, effectively radiating the entire cell from the corner. The reused frequency groups are aligned along the 0.degree., 120.degree., and 240.degree. axes of each tri-cell group. The frequency groups are reused in the same direction along each axis, reducing the number of dominant interfering cells to one.
