An allotment of a radio frequency or radio frequency channel is a designated frequency channel in an agreed plan for use by an administration to provide coverage over a defined area, called the allotment area. Transmitter sites and their characteristics can be varied by the administration, as long as the agreed reference values at the edges of the geographic area are respected.

An allotment planning is used mainly for broadcasting. An allotment planning is based on one or more reference networks. An allotment planning gives more flexibility than a plan that is based on fixed transmission sites and their characteristics. This is called an assignment plan.
