Coexistence Interference Analysis of 28 GHz IMT and Fixed-Satellite Service Systems

摘要

In this paper, the coexistence interference of 28 GHz-band International Mobile Telecommunications (IMT) and fixed-satellite service systems is analyzed based on actual satellite orbit and coverage information. Specifically, the aggregate interferences of IMT system base stations (BS) to fixed-satellite service networks are studied, considering IMT base station antennas with a large range of elevation angles from 10° to 90°. Moreover, rain attenuation is considered in 28 GHz system link budget analysis. The results show that the IMT base station uplink deployment can coexist with the fixed-satellite service in the band. The provided results are useful for design of future 28 GHz wireless communications systems and fixed-satellite service networks.
