Program for selecting an optimum access point in a wireless network
First Claim
1. A non-transitory computer readable medium having embodied therein a computer program instructions for use by a wireless communication device associated with a current access point on one channel, the computer program instructions configured to cause the wireless device to implement operations comprising:
- ascertaining whether the wireless device should attempt to associate with another access point operating on another channel; and
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,wherein the ascertaining includes ascertaining that the wireless device should attempt to associate with another access point operating on another channel if the access point on said another channel is closer to the wireless device than the current access point, based on a distance measure computed for a particular access point using a received power from the particular access point and a transmit power backoff value associated with the particular access point.

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.

13. A wireless communication device comprising:
-
a processor that, in a state in which the wireless device is associated with a current access point operating on one channel, is configured to; ascertain whether the wireless device should attempt to associate with another access point operating on another channel, including ascertaining that the wireless device should attempt to associate with another access point operating on another channel if the access point on said another channel is closer to the wireless device than the current access point, based on a distance measure computed for a particular access point using a received power from the particular access point and a transmit power backoff value associated with the particular access point; and request 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. - View Dependent Claims (14, 15, 16, 17, 18)
