ABSTRACT:
A smart antenna steering algorithm operates in response to different functions monitored by the media access control (MAC) layer within a client station. One function is when the MAC layer indicates that the client station has been placed in a power savings mode. In response, the antenna algorithm stores an index of the currently selected antenna. Another function is when the MAC layer indicates that the client station has not been synchronized, associated and authenticated with an access point. In response, the algorithm selects an omni-directional antenna beam as the default antenna beam. Another function is when the MAC layer provides beacon period synchronization information to the antenna steering algorithm so that the algorithm can update its own timer.
