Abstract
Multichannel dynamic frequency selection in wireless networks begins with an access point for a wireless network broadcasting a list of unused channels that are available for communication within the area served by the access point. The various access terminals within this service area receive the broadcast and measure various interference characteristics of each of the channels in the list. The access terminals then send this interference information to the access point, which compiles a matrix of interference information that is associated with the quality of each signal as related to each access terminal. Using this information, the access point selects the appropriate channels to serve the most number of access terminals at the highest possible channel qualities.
