Sharing and Electromagnetic compatibility studies between 5G networks and feeder links for mobile-satellite service in 6700-7075 MHz band

This work presents studies of electromagnetic compatibility between 5G networks and fixed-satellite service (space-to-Earth) operating as feeder links for mobile-satellite service. The study includes consideration of current sharing studies conducted in ITU-R. The study evaluated co-channel interference from 5G networks to fixed-satellite Earth stations operating as feeder links to mobile-satellite service taking into account urban and suburban deployment scenarios of 5G networks. The study analyzes the 5G impact to currently operating Earth stations in Russia of the Globalstar network and uses the results to obtain cross-border scenario compatibility conditions. The obtained results show the required protection (coordination) distances between receiving Earth stations and 5G network transmitters for urban and suburban 5G deployments.
