1、QUESTION ITU-R 133-1/5*,*Sharing criteria between the fixed and land mobile services in thefrequency bands above about 0.5 GHz(1990-2002)The ITU Radiocommunication Assembly,consideringa) that due to the growing demand on the radio frequency spectrum, there is a need to improvefrequency sharing betwe
2、en different services;b) that there is a particularly strong need for land mobile and fixed services, includingnomadic wireless access (NWA) and fixed wireless systems, to share frequencies above about0.5 GHz;c) that with appropriate sharing criteria, the fixed service can use spectrum required form
3、obile purposes;d) that criteria for fixed/mobile sharing have not been determined in many frequency bandsabove 0.5 GHz;e) that the necessary technical characteristics relevant to sharing are not known;f) that there is a need to develop sharing criteria on a world-wide basis, considering thespecial r
