Abstract: A device for assigning radio channels to radio transceiver devices. The device comprises an interface configured to receive two or more radio communication values, each associated with a radio transceiver device. The device comprises a processor configured to calculate an ordering of two or more radio transceiver devices based on radio communication values and build, according to the ordering, one or more rooted tree representing assignment of available radio channels to first radio transceiver devices according to the ordering. A branch of the rooted tree is selected according to a cost function value calculated along each branch. The processor is configured to assign the available radio channels to the radio transceiver devices according to the selected branch.

Abstract: An apparatus and a method for providing an efficient multi-client access in a WLAN, the method comprising the step of: when the number of clients exceeds a threshold, creating at least two virtual access points (VAP1, VAP2, VAP3); load balancing by distributing workloads across the created at least two virtual access points; and dynamically allocating at least one quality of service parameter (e.g., timeslots, AIFS, TXOP, maximum and minimum contention window) to each of the created at least two virtual access points.

Abstract: A beamforming method and a beamforming apparatus for directional signal transmission are provided, wherein a multiple antenna beamformer is configured to conduct a data transmission to a beamformee.
