Analysis of the Interference Environment Generated by Mobile Earth Stations Operating in Frequency Bands Shared with the Fixed Service

Abstract

This paper examines the construction of the coordination contour for mobile (except aeronautical mobile) earth stations operating in frequency bands shared with the terrestrial services. The method used today by the national administrations for calculating the coordination contour around these stations is vague and leads to unnecessarily large coordination areas. A new method of developing the coordination contour is proposed for this type of stations. It is shown that the adoption of the method by the national administrations contributes considerably to the development and wide use of mobile earth stations and eases the harmonic coexistence of this service with the terrestrial services
