Abstract
A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device, determining (52) which UHF television broadcast channels are available for use by the user device and determining (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.
