Abstract
A system comprises a station manager for associating a queue block to each active station in a network, each queue block being configured to implement a contention-based process, e.g., IEEE 802.11e, to select a winning frame from a set of frames; a multiplexer for receiving frames, each frame having a destination address, and for routing each received frame to a queue block based on the destination address; an access controller for receiving the winning frame from each queue block, for forwarding the winning frame(s) to a physical layer for simultaneous transmission to the active station(s) when the number of winning frames is equal to or below a threshold greater than one, and for forwarding a subset of the winning frames to the physical layer for simultaneous transmission to the active stations when the number of winning frames is above the threshold; and a physical layer capable of simultaneous frame transmission.
