Abstract

An access point (22) for use in a wireless local area network (WLAN) (20) includes a plurality of antennas (30,32) and two or more transmitters (64), which are adapted to transmit downlink signals on different, respective downlink frequency channels of the WLAN via at least one of the antennas. Two or more receivers (70) are coupled to receive uplink signals via at least two of the antennas, and are adapted to receive the uplink signals simultaneously on different, respective uplink frequency channels of the WLAN.
