Satellite-Terrestrial Interference and Spectrum Sharing in the Upper Mid-Band

Satellite-Terrestrial Interference and Spectrum Sharing in the Upper Mid-Band

Research Overview

The upper mid-band from 7–24 GHz has attracted considerable interest to expand cellular services due to their balance of coverage and capacity. A key challenge for deploying terrestrial cellular service in the upper mid-band is the need to coexist with incumbent services, particularly commercial communication satellites. Low Earth Orbit (LEO) satellite mega constellations can enable new services and provide vital high-capacity coverage in rural areas where fixed infrastructure is costly. Due to their narrow beam widths and relatively low altitudes, the latest generation of satellites are particularly sensitive to terrestrial cellular systems, particularly high power base stations in rural areas. This project seeks to evaluate potential interference of terrestrial cellular services with satellite systems in the upper mid-band and develop methods to mitigate it.
