1. CONCLUSIONS



An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
this site will operate satisfactorily with the common carrier microwave environment. Further,
there will be no restrictions of its operation due to interference considerations.
