GateHouse SatCom is building NodeB to be integrated in Satellite networks in three different scenarios: 1) on the ground supporting transparent mode, 2) in the satellite supporting in-orbit processing and regenerative mode, and 3) at the remote side supporting backhauling of 5G services establishing a remote cell. We are working with suppliers of LTE and 5G Core Network, but unfortunately we have no insight into the complexity of integrating a cellular core into a satellite core. There are already existing satellite core networks build on 3G and 4G cell core networks offering mobile data services.
