Abstract

Summary In this paper, we investigate the possible satellite's role and technical solutions required for providing broadband services complementing the terrestrial fifth generation wireless standards. First, we review the satellite networks use cases, services, and system requirements. Then we investigate the satellite potential purpose for broadband service provision and the associated challenges with focus on the system and space/ground technological aspects. Different architectural satellite network solutions are illustrated jointly with the key system design trade‐offs. Particular emphasis is dedicated to the payload architecture. Finally, we illustrate the space and ground segment technologies enabling the successful satellite contribution to broadband services provision.
