Wireless LAN's have multiple non overlapping channels (3 for 802.11b and 12 for 802.11a). This allows multiple clients to transmit concurrently on separate channels. However each access point is set to one particular channel, by the LAN administrator when the WAP is installed. The installer would determine channel selection by physical location of each access point to avoid maximize spatial capacity. Typically, access points near each other are assigned different channels to best maximize concurrent bandwidth. Our invention is a solution to allow access points to change their fixed channel based on current usage to best maximize concurrent bandwidth, while saving the cost and delay incurred by a full site survey.
