Future 5G/6G mobile communication systems are expected to integrate various radio access technologies, including the satellite component. In this framework, terrestrial services can be augmented with the development of novel satellite systems (namely, UHTS GEO and mega-LEO constellations) to meet service needs in those areas that terrestrial 5G systems cannot cover. This webinar will survey the main outcomes achieved within the INGR Satellite working group. In particular, the following topics will be addressed in this webinar: survey of current most advanced satellite systems and architectures with particular attention to mega-LEO systems, possible use of mmWaves, Mobile Edge Computing, artificial intelligence, QoS/QoE requirements, and standardization aspects referring to the recent work by ITU, 3GPP, and ETSI. This webinar will be a good opportunity to present challenges and possible solutions for these key sectors towards future satellite systems.
