A client station in a wireless local area network (WLAN) communication system includes a beam commutation algorithm and a smart antenna responsive to the beam commutation algorithm for selecting one of a plurality of directional antenna beams. The smart antenna is configured as a virtual omni-directional antenna by using a commutation of switched directional antenna beams. A switched directional antenna system that performs a commutation sequencing can be blind to environmental conditions and changes.
