9、on of the methodologies to facilitate coordination and use of frequency bands shared between the mobile-satellite service and the fixed service in the frequency range 1-3 GHz (Questions ITU-R 201/4 and ITU-R 118/5) (2000-2010) Scope This Recommendation provides an analytical index which identifies s
10、everal ITU-R Recommendations addressing various aspects of frequency sharing between the fixed service (FS) and mobile-satellite service (MSS). It also categorizes these Recommendations in order to facilitate their application. The ITU Radiocommunication Assembly, considering a) that various portion
11、s of the 1-3 GHz frequency range are allocated to the fixed service (FS) and that this service continues to be extensively used by many administrations; b) that recent world radiocommunication conferences have made new allocations to the MSS in the 1-3 GHz range; c) that most of the new allocations
12、for the MSS in the 1-3 GHz range have been established in frequency bands that were already allocated to the fixed service; d) that numerous ITU-R Recommendations have been established regarding various aspects of frequency sharing between the fixed service and MSS, and that an analytical index whic
13、h identifies and categorizes these Recommendations will facilitate their application; e) that in accordance with the Radio Regulations (RR) Article 9 and Appendix 7, a coordination area is determined to identify fixed service stations which could affect or be affected by the operation of mobile eart
14、h stations (MESs), and analyses, if required, may be needed in the course of coordination to further define the potential for interference and identify design and operating constraints that may be needed to resolve any difficulties; f) that in order to prevent interference between MSS (space-to-Eart
15、h) transmissions and receiving fixed service stations, the RR specify thresholds of pfd and fractional degradation in performance as well as a system-specific methodology (RR Appendix 5) to determine whether coordination is required, and analyses may be needed in the course of coordination to define
16、 the potential for interference and design and operating constraints that may be needed to resolve any difficulties, recognizing a) that the specific factors and methodologies applied in the course of coordination are subject to agreement of the parties concerned, and that the relevant ITU-R Recomme
17、ndations are intended to provide impartial technical advice that may facilitate the coordination process; *This Recommendation should be brought to the attention of Radiocommunication Study Group 5. 2 Rec. ITU-R M.1471-1 b) that the technical aspects of coordination of frequency assignments for fixe
18、d service and MSS systems are complex and may require application of analyses using complicated computer software; c) that the availability of ITU-R Recommendations relevant to coordination of fixed service and MSS frequency assignments may be particularly beneficial to developing countries in relat
19、ion to protection of their fixed service systems, their introduction of MSS systems within their territories, and the introduction of MSS systems in neighbouring territories; d) that administrations are submitting to the ITU Radiocommunication Bureau computer software that has been developed to faci
