Abstract

A wireless network infrastructure that adapts between single and concurrent interfering transmissions and receptions based on dynamically varying channel conditions. The channel conditions variations are typically determined by the number of associated wireless end point devices within the cell, their capabilities, anticipated bandwidth usage, QOS (Quality Of Service) demands, priority of service, idle states, cell overlap interferences, near-far interferences, and noises. The wireless network infrastructure supports a plurality of end point devices and contains an access point. The access point defines at least one first portion of a frame wherein transmissions and receptions are limited to single transmissions and receptions, and at least one second portion of the frame wherein concurrent interfering transmissions and receptions are permitted. The access point responds to the dynamically varying channel conditions by adapting a frame between the first portion that allows single transmissions and the second portion that allows concurrent interfering transmissions.
