The present invention provides in one embodiment channel allocation and polarization techniques for reducing cross sector communications interference in a multiple access wireless communications environment. In one embodiment, channel allocation and/or polarization techniques may be applied in multiple-access wireless communications architectures to provide selective, simultaneous communications with wireless devices using a plurality of transmitters. In some embodiments, a transmitter is coupled to an antenna configured to provide simultaneous communications with wireless devices located in different spatial areas or sectors. In some embodiments, communications between wireless devices within a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network may be provided.

Method and apparatus for sector channelization and polarization for reduced interference in wireless networks

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'. This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism. Wireless devices within a sector may communicate on the same or different communications channels, depending upon the particular multiple access protocol employed. For example, TDMA or CSMA may be used to allow wireless devices in a sector to share communications channels. Communications channels may also be used simultaneously in different sectors by different wireless devices.
