Broadcast license
A broadcast license is a type of spectrum license granting the licensee permission to use a portion of the radio frequency spectrum in a given geographical area for broadcasting purposes. The licenses generally include restrictions, which vary from band to band.[1]
Spectrum may be divided according to use. As indicated in a graph from the National Telecommunications and Information Administration (NTIA), frequency allocations may be represented by different types of services which vary in size.[2] Many options exist when applying for a broadcast license; the FCC determines how much spectrum to allot to licensees in a given band,[3] according to what is needed for the service in question.[1]
