Abstract

A cellular radiotelephone communications system comprising a system of cells that are made up of an array of directional sector antennas. These antennas are centrally located in the cell and radiates into a 60° area of the cell. Each antenna in a cell has a group of frequencies assigned to it that is different than the group of frequencies assigned to the other antennas within that cell. These frequency groups are repeated either 2 or 8 times respectively in a 4 or 16 cell repeat pattern, effectively forming a two cell reuse pattern. The preferred embodiment of this invention is asymmetrically positioning the repeating frequency groups in an alternating fashion so that one row faces in the opposite direction of another row. The asymmetrical positioning of cells is possible only by departing from the prior art, cellular positioning rules.
The positioning rules used in this invention create a 4 or 16 cell repeat pattern by locating co-channel cells closer in one direction than another.
