Abstract:
A method or apparatus steers a directional antenna for a station to communicate with an Access Point (AP) in an 802.11 protocol system. The method or apparatus may include setting the directional antenna in an omni-directional pattern during a Beacon scan. After authentication with a selected AP, the method or apparatus conducts an antenna beam selection process to determine a “best” direction for communicating with the selected AP based on a metric, such as Signal-to-Noise Ratio (SNR), of the Beacon frames received on each of the directional antenna scan angles. The method or apparatus may be integrated into or associated with a Medium Access Control (MAC) layer and receive signal quality metrics from the Physical (PHY) layer.
