Who controls the assignment of frequency usage?

Section 305 of the Act preserves for the President the authority to assign frequencies to all Federal Government owned or operated radio stations.

Frequency assignment is the authorization of use of a particular radio frequency .

The frequency assignment problem (FAP) basically aims to allocate, in an efficient manner, limited number of frequencies to communication links . Geographically close links, however, cause interference, which complicates the assignment, imposing frequency separation constraints.

Each assignment defines the particular purpose for which the frequency may be used and the conditions to be met so that the spectrum may be used efficiently and with minimum interference . No-one has the right to be assigned specific frequencies.
