Abstract
In this paper we review some of the work of the' Satellite Working Group' in the European Technology platform NETWORLD2020 towards a strategy for satellites in 5G. We first review the 5G vision and its drivers as defined by the terrestrial mobile community via the 5GPPP Association. We then outline the areas in which satellite can contribute to an integrated system within 5G and detail the research challenges that this provides. Finally we give views on a technology roadmap to meet these challenges such that satellites are ready by 2020 to play their part in the integrated 5G roll out.
