ABSTRACT:
A method for communication includes deploying a plurality of access points, which have respective coverage areas and are configured to operate on a common frequency channel, in a service region of a wireless local area network (WLAN), so that the coverage areas of the access points overlap. A first access point is selected to transmit downlink signals to a station in the service region of the WLAN at a certain downlink data rate. The station is instructed to transmit uplink signals at an uplink data rate that is less than the downlink data rate, so that the uplink signals can be received and decoded by both the first and second access points.
