It depends on the context of 5G support. If we talk about high-speed broadband, then we will probably have to wait some years. Using GEO satellites for 5G backhaul – being NR backhaul – will likely require new GEO satellites to be launched for the service. It is a scalable endeavor where just a few (3) GEO satellites could provide global coverage for a NTN broadband service and more could be added as the traffic load increases with adoption. For new GEO satellites, it would be wise to plan ahead for regenerative use-cases and potentially reconfigurability of service upon the end of the GEO satellite lifetime, e.g. by utilizing SDRs and FPGAs onboard. This ensure long-term rentability of the satellites after launch, even when their first targeted service case becomes deprecated. Also, it enables a switch of service IF the market for the preliminary service does not mature as expected after launch of the satellite. In the case of legacy GEO satellites, they may be useful for providing narrow-band NB-IoT cellular access to IoT devices on a global scale. Here, the same scalability applies, but in addition the satellites are already in-orbit and may be running deprecated services at little financial gain to their owners. According to GSMA Intelligence, there is an untapped D2D addressable revenue potential of $3obn, or 3% of existing telco revenue base – just on D2D. By narrowband use cases we mean IoT, messaging, Push-to-talk etc.
