The process of approving the use of radio communication through specific spectrum is called spectrum authorization. The spectrum manager does the following things for this purposes : 1. Approves the specific band of spectrum to users or group of users, 2. Makes sure that the allocated spectrum assignment happens in accordance with the national and international table of frequency allocations. Authorization is important to ensure efficient, and proper functioning of the scarce resource.
