Abstract

A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. In one embodiment, channel allocation techniques for increasing one or more of throughput and coverage in a wireless communications environment. In one embodiment, a mode of operation is selected from a plurality of modes of operation, enabling a wireless communications transmitter to be dynamically configured to reach a wireless communications devices at a greater distance from the transmitter without increased interference between communications channels (“range mode”) or to provide wireless communications to a greater number of wireless communications devices within a relatively closer distance to the wireless transmitter (“capacity mode”) or to provide wireless communications using a single channel to provide wireless communications at a relatively greatest distance from the transmitter (“super range mode”).
