ITU-R REPORT F.2108-2007 不同频段的固定业务系统参数

There is a large variety of fixed-wireless systems in operation or being developed to meet future requirements. This Report provides details of the key radio system characteristics and parameters for systems in the fixed service (FS).

ITU-T E.419 FRENCH-2006 网络和业务管理的商业化关键绩效目标.2号研究组

The scope of this KPI Recommendation is to find areas where meaningful measures can be identified and correlated to the broader business objectives. Often measurements are taken because they are available not because they are meaningful. It is envisaged that the model in this Recommendation will assist carriers to direct operations areas to play a more key role in supporting the business.

The ITU Radiocommunication Assembly, considering that research in radio astronomy depends critically upon the ability to make observations at the extreme limits of sensitivity and/or precision, and that the growing use of the radio spectrum increases the possibility of interference detrimental to the radio astronomy service (RAS).

Levels of data loss to radio astronomy observations and percentage-of-time criteria resulting from degradation by interference for frequency bands allocated to the radio astronomy on a primary basis Question ITU-R 227/7

ITU-R SF.674-2 FRENCH-2002 当区域2中的静止卫星固定业务网络超过决议77(WRC-2000)中的功率通量密度阈值时,对运行在11.7-12.2 GHz频段内的固定业务影响的测定

This Annex expands upon the methodology that is used in Recommendation ITU-R F.1107 for analogue FS systems and Recommendations ITU-R F.1107 and ITU-R F.1108 for digital FS systems. Recommendation ITU-R SF.358 provides guidance as to how satellite network pfd levels that protect the FS should be determined. Appendix 1 to Annex 2 of that Recommendation indicates that the absolute values of pfd should be selected in such a way that the maximum permissible interference power of Recommendation ITU-R SF.357 (1 000 pW) would be exceeded in a small fraction of the FS systems sharing that band for analogue FS stations. Recommendation ITU-R F.1108 uses the concept of fractional degradation of performance (FDP) for digital FS stations. The FDP is the fractional increase in the percentage of time that the controlling performance criterion will not be met because of the presence of interference. Recommendation ITU-R F.1108 suggests a value of 10?% for FDP as appropriate for sharing studies. Accordingly, the methodologies described here will determine the fraction of FS receivers for which the FDP will exceed 10%. The FDP should exceed 10% for no more than an agreed small percentage of the terrestrial stations. Appendix 1 discusses the methodology used to analyse interference into analogue fixed systems and Appendix 2 discusses the methodology used to analyse interference into digital systems. It should be noted that neither of the methodologies presented here makes use of any orbital avoidance.

This Recommendation covers the degradation of equipment performance due to induced noise voltage on metallic pair cables (including residential inside wire), which is caused by an inducing source external to the cable or by another telecommunication system. However, this Recommendation does not cover interference caused by transmission characteristics of cables (for example, cross talk characteristics).
