Frequency Coordination

A database search is performed to identify a frequency or frequency pair that meets the required FCC Interference co-channel separation criteria specified in part 101.105:

Fixed to fixed:145 km
Fixed to mobile:113 km
Mobile to mobile:81 km

Industry Canada

Coordination with Canada is required when the proposed system will be operating close to the United States-Canada border. An existing agreement with Canada defines the arrangement under which existing systems along the border must be protected. FCC part §1.928 provides the frequency coordination arrangement, and can be found here.

General Guidelines on coordination and use of radio frequencies between the United States and Canada can be found in appendix I of form 601 here.
