Abstract:Currently, the frequency band 1695-1710 MHz is under consideration by some administrations as the potential candidate band for IMT systems under Agenda Item 11 of WRC15 According to the ITUR Radio Regulations (Edition of 2012), the band 1695-1710 MHz is allocated to the meteorological satellite service (spacetoearth) on a primary basis, Chinese FY geostationary (GSO) and nonegeostationary (NGSO) satellites also use this band for data transmission. In order to ensure that no unacceptable interference is caused by IMT base stations into FY satellites in the band 1695-1710 MHz, this study provides an analysis of the frequency compatibility from IMT base stations to GSO and NGSO meteorologicalsatellite systems, respectively. Based on the interference simulation analysis results, it appears that sharing between meteorological satellite service and IMT base stations in this frequency band is not compatible.
