Technical Compatibility Challenges Between Fixed Satellite Service Earth Stations and 5G in C-band Downlink Spectrum

C-band Fixed Satellite Service (FSS) satellites have been providing services to businesses, governments, and consumers for over 50 years and continue to be a critical enabler of socio-economic development around the world.

Since their inception, governments, commercial enterprises, and users of all kinds – not to mention satellite operators – have invested billions of dollars in C-band satellites and ground infrastructure, and today there are about 200 geostationary satellites in orbit using C-band frequencies.
