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.

4. Apparatus capable of communicating in a wireless communications environment via a radio frequency channel, comprising:
-
logic for maintaining a known devices table, wherein the known devices table includes an entry for each other device operating on the radio frequency channel, and wherein for each entry, a backoff value is recorded for each other device, the backoff value for each device indicative of an amount that the device'"'"'s power has been adjusted;
logic for setting the transmit power of the apparatus to a level equivalent to the apparatus'"'"' maximum transmit power minus the maximum of the backoff values recorded for each other device. - View Dependent Claims (5)
