SATis5 aims to build a large-scale real-time live end-to-end 5G integrated satellite terrestrial network proof-of-concept testbed. The demonstrator testbed implements, deploys and evaluates an integrated satellite-terrestrial 5G network, showcasing the benefits of the satellite integration with the terrestrial infrastructures as part of a comprehensive communication system.
