摘要: White space devices (102) are unlicensed radiofrequency that must have certain capabilities in order to avoid harmful interference licensed operations. In general, they be location-aware, able contact a geolocation database (108) and may not operate without receiving positive control signal. A number of white can use channel (104) communicate with station (106). addition meeting the requirements given above, coordinates channels used by so as minimize (308) their aggregate interference. one embodiment, uses separate frequency band high availability reliability but low throughput. Embodiments optimize assignments where potential depends on mutual distances between devices. Potential reductions 20-30 dB been found simulations. Other embodiments disclosed.
