Abstract
An apparatus, method and system are provided for topological channel assignment for focused beam, fixed wireless telecommunications. The preferred system embodiment includes a plurality of transceivers coupled to a telecommunications switch, in which each transceiver utilizes a narrow focused beam on the order of ten degrees, for full duplex communication with fixed customer premise equipment. The geographic region is topologically divided, preferably, into a plurality of adjacent cells, in which each adjacent cell utilizes a distinctive, orthogonal code set from a 10 MHz spectrum. As channels, the various code assignments may be dynamically determined at any given time. The switch includes instructions for determining the cell configurations, determining an available channel (code) set for a selected cell, and within the selected cell, determining the plurality of focused beam ranges to create a corresponding plurality of sectors. Within each sector, the focused beams of the adjacent sectors typically spread or interfere into the given sector, creating interference regions. The switch includes further instructions for determining a plurality of channel subsets for the corresponding plurality of sectors, wherein each channel subset consists of the available channel set excluding an exclusion channel subset of a plurality of exclusion channel subsets; and for each interference region, the switch includes further instructions for assigning the exclusion channel subset of an adjacent sector of the plurality of sectors.
