prior coordination notice definition
Prior coordination is required by the FCC and begins when the system design is complete. Prior coordination requirements differ based upon the FCC rule section that your service falls under (eg. Part 101, Part 74 or Part 78). After frequencies are selected, a Prior Coordination Notice (PCN), including a path data sheet, must be sent to all existing microwave users in the area to notify them of the proposed path. The FCC rules state that existing users have 30 days to object to the proposal.
