A system includes a first primary wireless system (120) that communicates over a first range, and a first beaconing device (130) associated with the first primary wireless system (120). The first beaconing device (130) communicates over at least at a second range, wherein the second range is greater than the first range. The first beaconing device listens for beacons (510) from other beaconing devices (130) associated with other primary wireless systems (120) on a plurality of channels over which the other primary systems may operate. After listening for beacons from the other beaconing devices (130) associated with other primary wireless systems, the first beaconing device transmits a first beacon (510) to a wireless device (114) of a secondary wireless system (110) that may communicate over the second range. The first beacon includes data indicating an occupation of a first one of the channels by the first primary wireless system (120).
