Antenna steering for an access point based upon spatial diversity
First Claim
1. A method for operating an access point in a wireless local area network (WLAN), the access point comprising a directional antenna for communicating with at least one remote station, the method comprising:
- communicating with the at least one remote station using a current angle of the directional antenna;
scanning an alternate angle from a plurality of alternate angles of the directional antenna for communicating with the at least one remote station;
measuring respective signals received via the current angle and the alternate angle from the at least one remote station; and
selecting the current angle or the alternate angle as a preferred angle based upon the measured signals for continuing communications with the at least one remote station.

Abstract
A method for operating an access point in a wireless local area network is provided, wherein the access point includes a directional antenna for communicating with at least one remote station. The method includes communicating with a selected remote station using a current angle of the directional antenna, and scanning an alternate angle from a plurality of alternate angles of the directional antenna for communicating with the selected remote station. Respective signals received via the current angle and the alternate angle from the selected remote station are measured. The current angle or the alternate angle is selected as a preferred angle based upon the measured signals for continuing communications with the selected remote station.

13. A method for operating an access point in a wireless local area network (WLAN), the access point comprising a directional antenna for communicating with at least one remote station based upon an exchange of packet data comprising a preamble and a data frame, the method comprising:
-
communicating with the at least one remote station using a current angle of the directional antenna during a preamble;
scanning through a plurality of alternate angles of the directional antenna for communicating with the at least one remote station during the preamble;
measuring respective signals received via the current angle and the plurality of alternate angles from the at least one remote station; and
selecting during the preamble the current angle or one of the plurality of alternate angles as a preferred angle based upon the measured signals for continuing communications with the at least one remote station. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An access point for a wireless local area network (WLAN) comprising:
-
a directional antenna; and
a controller connected to said directional antenna for control thereof, said controller selecting a current angle of the directional antenna for communicating with the at least one remote station, scanning an alternate angle from a plurality of alternate angles of said directional antenna for communicating with the at least one remote station, measuring respective signals received via the current angle and the alternate angle from the at least one remote station, and selecting the current angle or the alternate angle as a preferred angle for continuing communications with the at least one remote station based upon the measured signals. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
