Escape mechanism for a wireless local area network
Abstract
A method for performing frequency selection escape in wireless communications is disclosed. The method includes receiving an activation trigger, determining whether the activation trigger has persisted for a predetermined period of time, determining a list of candidate channels; selecting a channel from the candidate list, and evaluating the selected channel against predetermined criteria, the predetermined criteria being related to the activation trigger. If the selected channel meets the predetermined criteria, then an access point (AP) is disassociated from all stations communicating with the AP; and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list; and the selecting of a channel is repeated if there are additional candidate channels.
