Abstract:
1. A method for communication, comprising: deploying a plurality of access points, comprising at least first and second access points, which have respective coverage areas and are configured to operate on a common first frequency channel, in a service region of a wireless local area network (WLAN), so that the coverage areas of the access points overlap, wherein the first access point comprises at least a first radio transceiver, which is configured to operate on the first frequency channel, and a second radio transceiver, which is configured to operate on a second frequency channel, adjacent to the first frequency channel; selecting the first access point to transmit downlink signals on the first frequency channel to a station in the service region of the WLAN; setting a downlink data rate for transmission of the downlink signals from the first access point to the station; instructing the station to transmit uplink signals on the first frequency channel at an uplink data rate that is less than the downlink data rate, so as to enable both the first and second access points to receive and decode the uplink signals on the first frequency channel while the second radio transceiver transmits downlink signals on the second frequency channel; and while the first radio transceiver at the first access point is receiving the uplink signals on the first frequency channel, instructing the first access point to delay transmission of the downlink signals on the second frequency channel.
