Program for adjusting channel interference between devices in a wireless network
First Claim
1. A computer-readable medium encoded with a program product for use in a first fixed-location device capable of communicating in a wireless communications environment via a radio frequency channel, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:
- logic for maintaining a known devices table, wherein the known devices table includes an entry for each other fixed-location device operating on the radio frequency channel, and wherein for each entry, a backoff value is recorded for each other fixed-location device, the backoff value for each fixed-location device indicative of an amount that the fixed-location device'"'"'s power has been adjusted;
logic for setting the transmit power of the first fixed-location device to a level equivalent to maximum transmit power minus the maximum of the backoff values recorded for each other fixed-location device.

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.
