Abstract
A central registration system provides channel maps of available spectrum channels to radio devices. The channel map indicates relative noise floor amounts among the available channels. For this purpose, an amount of predicted interference caused by high-power protected transmitters on each channel available to the requesting radio device for wireless communications is determined, where interference from primary channel and out-of-band emissions of the transmitters is considered.
