Abstract:
1. A wireless device, comprising: a wireless transceiver; dynamic frequency selection logic coupled to the wireless transceiver for selecting an operating frequency for the wireless transceiver; a network interface coupled to the dynamic frequency selection logic and responsive to receiving a signal from a remote primary spectrum user detector to forward the signal from the remote primary spectrum user detector to the dynamic frequency selection logic; a timer coupled to the network interface for determining the elapsed time from the last signal received from the remote primary spectrum user detector; and primary spectrum user detection logic coupled to the timer and the dynamic frequency selection logic responsive to the timer to activate after a predetermined time has elapsed; wherein the dynamic frequency selection logic is responsive to the signal from the remote primary spectrum user detector for selecting the operating frequency for the wireless transceiver; and wherein the dynamic frequency selection logic is responsive to the primary spectrum user detection logic for selecting the operating frequency while the primary spectrum user detection logic is active.
