Coexistence Study Between 5G Network and Terrestrial and Satellite Services Operating In 23–27.5 GHz Frequency Bands

Abstract

The global bandwidth shortage facing the mobile operators has motivated the exploration of the underutilized millimetre wave (mm-wave) frequency spectrum for the emerging fifth generation (5G) broadband cellular communication networks. The Radio sector of the International Telecommunication Union (ITU-R) allocated these frequencies during the World Radio Conference in 2019 (WRC-19). This thesis was part of the studies discussed during the ITU-R study period in preparation for the WRC-19. The studies conducted in this thesis focus on simulating deployments of 5G network in Cairo city in Egypt. The level of the aggregated interference from 5G network towards the other communication services operating in the same band or in the guard band were used to identify the protection criteria for these services. The result of the studies show possible compatibility between 5G network and other services with some considerations during the deployment of 5G network regarding various parameters, such as separation distance, guard band, antenna tilting and specific Out Of Band Emission (OOBE) levels from both 5G base station and user terminal.
