The methodology presented in this Annex is based on the assumption that fading in the 38 GHz and 40 GHz bands is dominated by rain and that, therefore, even if long-term interference has an effect on the performance of the link, the main way to have an outage of the FS link is to have an interference level higher than the fade margin of the link, whatever the propagation conditions may be.

The ITU Radiocommunication Assembly considering: a) that emissions from the earth stations as well as from the space station of a satellite network (GSO FSS; non-GSO FSS; non-GSO mobile-satellite service (MSS) feeder links) in the FSS may result in interference to another such network when both networks operate in the same bands; b) that it is desirable to have a common methodology of simulation for assessing interference between systems that have co-frequency, codirectional feeder links when one of the systems is non-GSO; c) that it is possible to make some simplifying assumptions for these systems; d) that the simplifications in considering c) should not adversely affect the output results; e) that it would be desirable to have a common set of input parameters for each of the two communication systems; f) that it is necessary for the methodology to consider the type of fade compensation to counteract signal fading such as adaptive power control; g) that the methodology should have the ability to accurately calculate the time dependence of a single interference event in order to more accurately assess the impact on the interfered system; h) that the vast majority of the non-GSO FSS systems are in circular orbits; j) that information on the numbers and precise locations of earth stations is usually unavailable from ITU sources.
