The Potential of Non-Terrestrial Networks for 6G

Описание: Professor Michele Zorzi , Professor of Telecommunications at the School of Engineering of the University of Padova, Italy came to Northeastern University on December 12th and gave a seminar on The Potential of Non-Terrestrial Networks for 6G


Many organizations recognize non-terrestrial networks (NTNs) as a key component to provide cost-effective and high-capacity connectivity in future 6th generation (6G) wireless networks. Despite this premise, there are still many questions to be answered for proper network design, including those associated with latency and coverage constraints. In this talk, after reviewing research activities on NTNs, we present the characteristics and enabling technologies of NTNs in the 6G landscape, and shed light on the challenges in the field that are still open for future research. As a case study, we evaluate the potential of multi-layered hierarchical networks, i.e., the orchestration among different aerial/space platforms, including High Altitude Platforms (HAPs) and satellites co-operating at different altitudes, and provide guidelines on the optimal working point(s) for which it is possible to achieve a good compromise between improved system flexibility and network performance, with respect to a baseline standalone deployment.
