Frequency coordination


Frequency Coordination is a technical and regulatory process that removes or mitigates radio-frequency interference between different radio systems that operate on the same frequency.
Normally frequency coordination is a function of an administration, such as a governmental spectrum regulator, as part of a formal regulatory process under the procedures of the Radio Regulations.
Before an administrations lets an operator operate a new radio communications network, it must undergo coordination in the following steps:
This coordination ensures that:
Coordination is thus closely bound to date of protection or priority, defined by the date when the International Telecommunication Union receives complete coordination data. New planned networks must coordinate with all networks with an earlier date of protection but are protected against all networks with a later date of protection. Planned networks acquire status under this procedure, but time limits ensure that protection does not last forever if networks are not implemented.
Congress Authorizes FCC
In 1982, the United States Congress provided the FCC with the authority to use frequency coordinators:
