In telecommunications, an allotment plan refers to a plan that governs the allocation of radio frequencies for use in wireless communications. It is typically used by regulatory bodies such as the Federal Communications Commission (FCC) in the United States, to ensure that the use of the radio spectrum is efficient, equitable, and does not interfere with other services. The allotment plan specifies which frequencies can be used in which geographic areas, and by which types of services. It also provides a framework for resolving conflicts between different users of the radio spectrum.
