Abstract

Wireless communication methods and systems using multiple sectored cells. In one example, each cell of a cellular coverage area is divided into a number of sectors. A number of different half duplex or full duplex channels are used in each cell to communicate between a base station and a number of subscriber stations located in the cell. At least some of the channels may be reused in other cells of the coverage area. Additionally, some channels may be reused both amongst sectors of a given cell and in other cells of the coverage area. The sectored cells are arranged with respect to one other such that interference amongst similarly oriented sectors of different cells using one or more same channels is reduced. In another example, two adjacent cells are arranged with respect to each other such that sectors of the two cells that are similarly oriented approximately along a bore axis of the two cells, and in which radiation is transmitted in the two cells in essentially a same direction approximately along the bore axis, use different channels.
