Abstract
We examine methods to extend IEEE 802.11 to incorporate adaptive antennas, thereby enhancing security. The focus is on the adaptation that is required to the overall system to take advantage of adaptive antennas. We consider a system architecture that makes use of beamforming antennas and power control to take advantage of the multiple propagation channels typically available in WLAN applications.
