Abstract
There is provided a system and method of sensing a radio frequency channel to determine activity, determining location, mapping location to existing radio frequency licenses, determining the radio frequency channel to be available and sharing that the radio frequency channel is available. Systems implementing this method may use a single device to perform the method steps or may use several different devices to share the complexity and workload associated with the method. This method is applicable to white space radio and to cognitive radio.
