Wireless communication method and apparatus for optimizing access point channel selection
First Claim
1. A method of selecting at least an optimal channel for use by an access point (AP) in a wireless communication system, the AP having at least an operating channel, the method comprising:
- (a) computing average loads of each of a plurality of neighboring base service sets (BSSs); and
(b) determining candidate channels among channel in an allowable channel set (ACS) for use by the AP; and
(c) selecting from the candidate channels a channel used for a new operation channel.

Abstract
A wireless communication method and system for optimizing channel selection for an AP. The channel selection optimization process includes four sub-processes: 1) a measurement process; 2) a candidate channel determining process; 3) a channel selection process; and 4) a channel update process. Candidate channels used for supporting communication performed by the AP are determined. The candidate channels are chosen from an allowable channel set (ACS) if a detected interference of each candidate channel is less than an established maximum allowed interference.

8. An access point (AP) for automatically selecting a channel for the AP in a wireless communication system, the AP comprising:
-
(a) means for periodically scanning through a plurality of different channels;
(b) means for invoking a channel optimization process if the AP is operating during a period of low load, wherein a predicted channel load is calculated based on high load measurements and the AP selects and changes its operating channel to the channel with the lowest predicted channel load.

11. An integrated circuit (IC) for communicating with a plurality of access points (APs) in a wireless communication system, the IC comprising:
-
(a) a measuring unit for measuring operating parameters of each channel in an allowable channel set (ACS) upon activating the IC;
(b) a power controller for controlling transmission power of the IC based on the operating parameters;
(c) a channel selector for selecting a channel used by the IC for communication based on the measured operating parameters; and
(d) a timer for setting a time period during which a beacon frame is transmitted from the IC to announce the operating parameters to the APs. - View Dependent Claims (12, 13, 14, 15)
