Telemetry, tracking & command (TT&C) earth stations (ES) constitute a sensitive part of the communication critical infrastructure in satellite networks, because harmful interference to TT&C channel can cause the total loss of communication with the space station. The ITU WRC 20191 identified frequency bands to be shared by 5G (IMT-2020) and satellite systems, including the 40 GHz band, which requires interference mitigation techniques. This work presents and discusses simulation results to evaluate the effectiveness of characterizing a zone (Protection Belts) where 5G base stations (BSs) could operate under more restrictive configurations to protect from harmful interferences the satellite downlink TT&C channels operating at the 40 GHz band. The “protection belt” concept would reduce the need for a wide “silent zone” surrounding the TT&C earth station (ES). The simulations were performed with an open source tool [1]23 that complies with Recommendation ITU-R M.2101 [2]. For more realistic scenarios, our simulation shows the positive effects of reducing the aggregate I/N (interference-to-noise ratio) generated by 5G BSs as a result of more restrictive parameters for the 5G operation deployed nearby the TT&C earth station, avoiding cochannel harmful interference.
