Apparatus for associating access points with stations using bid techniques
First Claim
1. Apparatus for use in an access point in a wireless communications environment including multiple access points and stations, wherein stations gain network access by associating with one or more of the access points, comprising:
- logic for collecting bid messages from stations, each bid message being a request from one station to associate with the access point and including a parameter related to the distance between the access point and that one station;
logic for selecting one of the bid messages based at least in-part on the parameter related to distance; and
logic for sending an accept message to the station which sent the selected bid message, the accept message for causing the station to associate with the 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.

-
logic for collecting bid messages from stations, each bid message being a request from one station to associate with the access point and including a parameter related to the distance between the access point and that one station; logic for maintaining a table including an entry for each station from which a bid message has been received, each entry including the parameter; logic for selecting one of the bid messages based at least in-part on the parameter indicating the closest distance; and logic for sending an accept message to the station which sent the selected bid message, the accept message for causing the station to associate with the access point.
