US 2004/0166844 A1 · Method for self-adjusting power at a wireless station to reduce inter-channel interference

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.

Claims5

Dependent claims

Apparatus for use by a wireless device in a wireless communications environment including multiple access points and stations, wherein stations gain network access by associating with one of the access points, comprising:

logic for associating with a current access point on one channel;
logic for ascertaining whether the wireless device should attempt to associate with an access point operating on another channel;
logic for requesting association with the access point operating on another channel if it is ascertained that the wireless device should attempt to associate with said access point.

Dependencies are inferred from the claim text.
