Interference Analysis between 1800MHz NR System and Meteorological Satellites System Using ITU-R Model

In this paper, based on the ITU-R P.452+P.2108 propagation model, a deterministic analysis is carried out for the neighboring-frequency interference scenarios between 1800 MHz NR systems and meteorological satellite services. By calculating the propagation loss and geoid loss, and considering the parameters and characteristics of different systems, the interference isolation of 5G terminals to GSO FY-4 meteorological satellite earth station as well as NGSO FY-3 meteorological satellite earth station is derived. The results show that under the worst interference scenario, the isolation distance required for the coexistence of the two systems is less than 0.25 km. Therefore, the 5G system in the 1800 MHz band and the neighboring frequency meteorological satellite service can achieve good coexistence without additional interference protection measures.
