Satellites can provide wide coverage to complement and to extend the dense terrestrial cells, which is in line with the ubiquitous coverage targeted by 5G networks. Satellites have an important potential role to play in supporting the overall resilience by complementing other communications infrastructures. Satellites can support a resilient 5G network to mitigate the problems of overload/congestion to meet the 5G KPI “ensure for everyone and everywhere access to a wider portfolio of services and applications at lower cost”. Advanced satellite payloads and enhanced onboard processing can enable the satellite to cache specific user information.
