Title:

ANTENNA STEERING AND HIDDEN NODE RECOGNITION FOR AN ACCESS POINT

Document Type and Number:

WIPO Patent Application WO2004114457

Kind Code:

A3

Abstract:

A method for operating an access point (A) in a wireless local area network (WLAN) is provided. The access point (A) includes a directional antenna (200a) for communicating with a plurality of remote stations (120), and the directional antenna (200a) includes a plurality of antenna patterns. The method includes creating an antenna database by associating between the access point (A) and each remote station (120) a respective measured signal quality corresponding to the plurality of antenna patterns. The respective measured signal qualities are determined by the access point (A) based upon communications with each remote station (120). The method further includes determining for each remote station (120) a preferred antenna pattern based upon the antenna database, and selecting a remote station (120) and the corresponding preferred antenna pattern to communicate with. It is also determined based upon the antenna database and prior to communicating with the selected remote station (120), if any non-selected remote stations (120) have the potential of not being aware when such communications actually occurs.
