Program for self-adjusting power at a wireless station to reduce inter-channel interference
First Claim
1. A program product for a station capable of communicating in a wireless communications network 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 receiving a message from an access point, the message containing information about the access point'"'"'s power level;
logic for adjusting transmit power in response to the information in the message.

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.

5. A program product for a station capable of communicating in a wireless communications network 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 receiving a message from an access point, the message containing a transmit power backoff level that indicates how far the access point'"'"'s power has been reduced;
logic for adjusting transmit power by setting the station'"'"'s transmit power to the transmit backoff level received in the message; and
logic for transmitting messages to other devices in the wireless communications network, the messages including a power backoff level indicative of the amount by which the station'"'"'s transmit power has been adjusted.
