ITU-R SF.1572 SPANISH-2002 PDF

Scope: The ITU Radiocommunication Assembly considering a) that emissions from space stations in the fixed-satellite service (FSS) operating in geostationary orbit (GSO) and sharing the same spectrum as the fixed service (FS) may produce interference in receiving stations of the FS; b) results obtained using a statistical approach compared to a worst-case analysis may lead to a more efficient use of the spectrum than results from criteria developed using worst-case analysis; c) that sharing methodologies should take into consideration the performance requirements and deployment characteristics of FS systems being used and planned for use in these frequency bands; d) that in spectrum where precipitation is the predominant fade mechanism it is desirable to have an interference evaluation tool using C/N, C/I and C/(N + I) statistics to determine impact on availability; e) that such an interference evaluation tool may have application in bands above about 17 GHz to assist administrations in performing sharing studies.
