Abstract: One of the claimed challenges of 5G and beyond standards is to provide service continuity in network scenarios where the connection links are discontinuous. In this seminar, some very recent results will be shown concerning this topic. The first series of results will deal with the use of Unmanned Aerial Vehicles (UAVs) to develop a transparent multi-frequency relay network performing signal amplification and frequency conversion between a satellite-based 5G network and User Equipment (UE). The claimed objective of the considered approach is to guarantee the link continuity also in the unpleasant case of disruption of the wireless terrestrial coverage. The second series is related to an experimental testbed leveraging Multi-Access Edge Computing (MEC) to maintain service availability in a satellite-aided 5G network configuration, where the terrestrial coverage is reduced or even missed. The global outcomes of the research work shown in the seminar will provide some guidelines to the design and implementation of robust radio network configurations capable of tackling emergency situations and solving urgent digital-divide issues.

Bio: Claudio Sacchi received the “Laurea” degree in Electronic Engineering and the Ph.D. in Space Science and Engineering from the University of Genoa, Italy, in 1992 and 2003, respectively. From 1996 to 2002, he was a Research Cooperator with the Department of Biophysical and Electronic Engineering (DIBE), University of Genoa, and with the National Italian Consortium in Telecommunications (CNIT), managing project activities in the field of multimedia surveillance systems and satellite communications. In August 2002, he joined the Department of Information Engineering and Computer Science (DISI), University of Trento, Italy, as an Assistant Professor. He was promoted to Associate Professor in December 2020. He has authored and coauthored more than 140 papers published in international journals and conferences. He is a member of the IEEE ComSoc, IEEE BTS, IEEE VT, and IEEE AESS. Since 2019, he has been coordinating and chairing the IEEE AESS technical panel: “Glue Technologies for Space Systems” that was awarded by AESS as “Outstanding Panel of the Year” in 2020 and 2021. Since January 1st, 2023, he has had double affiliation with UNM as Research Professor. His main research interests are related to emerging satellite and aerospace communications and broadband mobile communications in 5G and 6G systems
