The recent emergence of satellite and terrestrial integrated mobile systems raises new challenges for interference coordination between satellite and terrestrial users. The terrestrial component aims at improving the satellite coverage in highly populated areas where satellite communications often suffer from a high blocking factor caused by the buildings. The term “integrated system” refers to a...
This paper aims at forecasting the role of Satellite Communications (SatCom) in the context of Future Internet and particularly of the future Internet-enabled smart infrastructures in support of some European Societal Grand Challenges. It also aims at identifying the necessary technological enablers which need to be developed by the European SatCom industry for the emerging SatCom solutions.
