Abstract
A frequency allocation technique for a wireless system which employs remote subscriber Field Access Units (FAUs) that use omni-directional antennas in an inner region of a cell, and directional antennas in an outer region of the cell. Different frequency subsets are used for the inner and outer cell regions and FAUs located in the inner regions of homologous cells maintain separation from one another by limiting their operating power to a level needed to complete the radio link from the base station. A receiver portion of the base station has the capability to determine received signal power for each channel within the bandwidth being served. This provides the basic input for a channel selection algorithm which determines the quietest channel from among those channels not in use. A further constraint on the frequency allocation process is that a minimum number of channels always remain unused. That is, for example, among the available channels in each cell, only a subset of the channels are actually ever allowed to become active.
