Method for selecting an optimum access point in a wireless network on a common channel
First Claim
1. A method for use by a wireless device in a wireless communications environment, the method comprising the steps of:
- associating the wireless device with a current access point;
ascertaining, by the wireless device, whether the wireless device should attempt to associate with an alternative access point, the ascertaining based at least in-part on a level of attenuation of signal strength of transmissions by the alternative access point where the alternative access point transmits at less than full power; and
requesting association with the alternative access point if it is ascertained that the wireless device should attempt to associate with said alternative access point.

Abstract
The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
