Method for Selecting an Optimum Access Point in a Wireless Network on a Common Channel
First Claim
Patent Images
1. A method comprising:
- ascertaining whether a wireless device currently associated with a current access point should attempt to associate with another access point based at least in part on a level of attenuation of signal strength of transmissions transmitted by the another access point at less than full power; and
causing the wireless device to request association with the another access point if said ascertaining ascertains that the wireless device should attempt to associate with the another 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.

10. A non-transitory computer-readable medium having stored therein a computer program that, if executed by a processor of a wireless communication device, causes the wireless communication device to perform operations comprising:
-
ascertaining whether the wireless device should attempt to associate with another access point based at least in part on a level of attenuation of signal strength of transmissions transmitted by the another access point at less than full power; and requesting association with the another access point if said ascertaining ascertains that the wireless device should attempt to associate with the another access point. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. 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 based at least in part on a level of attenuation of signal strength of transmissions transmitted by the another access point at less than full power; and request association with the another access point if it is ascertained that the wireless device should attempt to associate with the another access point. - View Dependent Claims (19, 20)
