Satellite communication (SatCom) offers the prospect of service continuity over uncovered and under-covered areas, service ubiquity, and service scalability. In addition, the integration of SatCom, aerial networks, and terrestrial communications into a single wireless network, called space-air-ground integrated network (SAGIN), is deemed from now on crucial. However, several challenges must first be addressed to realize these benefits, as the resource management, network control, network security, spectrum management, and energy usage of satellite networks are more challenging than that of terrestrial networks. This panel will offer a general overview of emerging and future trends in SatCom. More specifically, the potential of SatCom and then the challenges facing diverse aspects of these systems will be discussed. The panel will also be a forum to debate the various proposed solutions.
