Frequency Coordination

Frequency coordination is required by the FCC and begins when the system design is complete. An interference analysis is performed to determine frequencies that will not cause harmful interference to other existing and proposed microwave paths and earth stations in a particular band.

After frequencies are selected, a Prior Coordination Notice (PCN), including a system data sheet, must be sent to all existing microwave users in the area to notify them of the proposed earth station. The FCC rules state that the existing users have 30 days to object to the proposal. Once the 30-day period expires and any objections are resolved, a supplemental showing must be included with your FCC license application.

To learn more about the frequency coordination process, you can download a white paper, Fundamentals of Earth Station Frequency Coordination.
