Spectrum for satellite services are likely to overlap with the ITU 5G spectrum. Critical satellite services may be impacted due to interference between various communication links working in the same frequency band. The worst-case interference scenario between Mobile Base Station (BS) and Satellite Earth Station (ES) is evaluated. Recommendation for path loss for 3.4 GHz operations are given based on ITU-R P.1546-5. Simulations are parameterized by ES height, BS height, terrain, time-variability and location-variability. © 2019 IEEE.
