Abstract:
1. A method of predicting an available link budget information for a secondary device operating in a spectrum of a primary system, the method comprising: gathering operating characteristics of the primary system and at least one of a plurality of secondary devices in a geo-location database, wherein the operating characteristics comprise at least a transmitter splatter level, transmitter location, antenna height, and antenna pattern, for the primary system and the at least one secondary device; computing, based on the operating characteristics in the geo-location database, an allowed transmission power level at a first location for a specified operating frequency of a first secondary device of the plurality of secondary devices, wherein the allowed transmission power level is computed based on allowable harmful interference levels to the primary system and proximity of the first secondary device to the primary system; predicting, based on the operating characteristics in the geo-location database, an aggregate interference level at a second location for the specified operating frequency of a second secondary device of the plurality of secondary devices; predicting an available link budget at the second location for the specified operating frequency based on the difference between the computed allowed transmission power level at the first location and the aggregate interference level at the second location.
