Abstract
The present invention is based on a tri-cellular grouping of three identical cells. Each cell of the tri-cellular group is driven by a directional antenna that radiates the cell from the center of the group. Multiple tri-cellular groups make up a cellular system having three axes at 0.degree., 120.degree., and 240.degree.. Each axis is comprised of seven total layers, one layer being a repeat of another of the layers. The 512 available system PN offsets are divided up into three groups of 24 offsets, one group for each axis. Each PN offset group is reused only in the direction to which it is assigned.
