Abstract
A wireless access point (WAP) for wireless communication with associated stations on selected orthogonal frequency division multiplexed (OFDM) communication channels of a wireless local area network (WLAN). The WAP includes: an array of antennas having a number of spatial states, a plurality of components coupled to one another to form receive and transmit chains, and an antenna control circuit. The antenna control circuit couples to the plurality of components and to the array of antennas to determine for each uplink an optimal spatial state of the array of antennas for receiving said uplink; and to change the spatial state of the array of antennas for each uplink to match the optimum determined spatial state therefore.
