SECTORIZED WIRELESS COMMUNICATION NETWORK OPERATING UNDER 802.11 SPECIFICATIONS

摘要

Methods and systems are provided to facilitate communication with a plurality of remote units in a communication area that includes a plurality of spatial sectors. The system includes a network controller configured to receive and transmit under IEEE 802.11 specifications, and a plurality of directional antennas coupled to the network base station. Each of directional antennas functions as an access point for a respective spatial sector. The directional antennas and the network controller are combined as a single base station apparatus in an exemplary embodiment. Further, an exemplary network controller is configured to concurrently transmit a plurality of the data frames to more than one of the spatial sectors, and to synchronize the transmissions in a manner whereby all of the concurrently transmitted frames end simultaneously.
