Abstract

A wireless network infrastructure that adapts encoding approach and frame parameters of concurrent interfering transmission and receptions in response to dynamically varying channel conditions. The channel conditions are determined by number of associated wireless end point devices within a cell, their capabilities, anticipated bandwidth usage, QOS (Quality Of Service) demands, priority of service and idle states, cell overlap interferences, near-far interferences, and noises. The wireless network infrastructure consists of an access point that is adapted to receive and transmit concurrent interfering transmissions utilizing a plurality of encoding approach and frame parameters. In addition, the wireless network infrastructure consists of a plurality of end point devices that are adapted to transmit and receive using concurrent interfering transmissions with one or more of the plurality of encoding approach and frame parameters.
