Patent attributes
A wireless transceiver for wireless communications on a selected orthogonal frequency division multiplexed (OFDM) communication channel of a wireless local area network (WLAN). The transceiver includes: a number of antennas, a plurality of components, and a beamform antenna selection circuit. The plurality of components are coupled to one another to form receive chains and transmit chains lesser in number than the number of antennas, and switchably coupled to the antennas for multiple-input multiple-output (MIMO) wireless communications on the OFDM tones of the selected communication channel. The beamform antenna selection circuit couples to the plurality of components and to the antennas to select a highest ranked subset of the antennas to couple to the transmit chains by sounding a targeted transceiver on the WLAN with the number of antennas and by switchably coupling the transmit chains to the highest ranked subset of the antennas for beamformed transmission of subsequent data communication packets to the targeted transceiver.
