1、QUESTION ITU-R 244/5*Improvements to Recommendation ITU-R F.758(1999)The ITU Radiocommunication Assembly,consideringa) that Recommendation ITU-R F.758 presents useful information for consideration in thedevelopment of criteria for sharing between the fixed service (FS) and other space and terrestria

2、lservices;b) that various tables in Recommendation ITU-R F.758 give typical parameters of FS systemsfor use in frequency sharing studies;c) that the size of the Recommendation is growing owing to the many new FS systemsemerging, but that it is preferable to keep the size of the Recommendation within

3、 a reasonable limit;d) that a uniform presentation of FS system parameters is desirable in order to facilitate theuse of the Recommendation;e) that the principal stated purpose of the Recommendation is to provide essential technicalcharacteristics and sensitive sharing parameters of FS systems that

4、need to be taken into accountwhen developing criteria for sharing with other services,decides that the following Questions should be studied1 What is the preferred methodology for revision and reorganization of RecommendationITU-R F.758 with the objective of simplifying and/or condensing its content

5、s in a mannerconsistent with the stated purpose of the Recommendation?2 What is the preferred unified format to be used by administrations for submittingparameters of FS systems for inclusion in Recommendation ITU-R F.758?3 What are the additional data and information to be included in RecommendationITU-R F.758 in order to facilitate studies in various frequency sharing situations?further decides1 that the result of the study should be in the form of revision of RecommendationITU-R F.758 to be completed by the end of 2005._* Former Question ITU-R 225/9.
