Currently, the frequency band 1695-1710 MHz is under consideration by some administrations as the potential candidate band for International Mobile Telecom (IMT) systems at the World Radio Communication Conference According to the Radio Regulations (Edition of 2012), the band 1695-1710 MHz is allocated to the meteorological satellite (MetSat) service (spacetoearth) on a primary basis In order to protect the earth stations of the Fengyun (FY) MetSats in the 1695-1710 MHz band, the characteristics of the FY earth stations and the IMT user terminals (UEs) are introduced The interference model from IMT UEs is build, and the interference into earth stations of geostationary (GSO) and nongeostationary FY satellites’ earth stations are simulated respectively The analysis results show that the separation distances of 46 km and 61 km are needed to prevent the aggregated interference from IMT UEs into GSO MetSat earth stations and nonGSO MetSat earth stations Considering the fact that almost every large and mediumsized cities of China have one or more typical MetSat receiving systems in the 16951710 MHz band, based on above study results, it is concluded that MetSat service and IMT applications in this frequency band are incompatible
