Channel selection in a wireless network

摘要

In order to achieve improved performance for users on a wireless network, it is desirable to reduce interference between wireless access points (APs or WAPs) by selectively assigning different channels to the radios of the APs in a-neighborhood. This may be performed by process whereby a central controller automatically assigns channels to one or more APs managed by that controller in accordance with a channel selection algorithm that considers received signal strength indication (RSSI) and transmit (Tx) or receive (Rx) error rates on channels of the radios. The algorithm also takes into account any stand-alone APs in the network (i.e., not connected to the network) and assigns the channels to managed APs in such a way as to avoid interference with the stand-alone APs.
