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.

2. A program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:
-
Logic for scanning a plurality of radio frequency channels during a scan interval;
Logic for receiving messages on the plurality of radio frequency channels during the scan interval;
Logic for maintaining a channel map having an entry for each of the plurality of radio frequency channels, and if one or more messages was received on a channel, the corresponding entry further including a device ID for at least one of the devices that sent a message on the channel;
Logic for selecting a channel from the channel map;
Logic for transmitting messages on the selected channel during a claim interval;
Logic for receiving messages on the selected channel during the claim interval;
Logic for ascertaining whether the apparatus should commence communications with other devices on the selected channel based upon characteristics of the messages received on the channel. - View Dependent Claims (3)
