CNR-IEIIT organizza una serie di seminari con frequenza bisettimanale denominata "Incontri del giovedì" in cui vengono affrontate con il supporto di relatori di rilievo nell'ambito della ricerca scientifica, accademica ed industriale le tematiche caratterizzanti l'Istituto stesso, con una visione trasversale ai domini applicativi ed agli ambiti tecnologici ed uno sguardo rivolto alla loro evoluzione.
Il seminario si è svolto in forma telematica giovedì 23 Febbraio 2023 alle ore 17:30 sulla piattaforma Microsoft Teams.

Titolo seminario:
An example of Innovative Technologies to Integrate Satellites into (Beyond)5G Terrestrial Networks: Formation-of-Arrays
Abstract:
Effective integration of terrestrial and non-terrestrial segments is one of the key research avenues in the design of current and future wireless communication networks. In this talk, we first show that such integration is hard to attain with the current status of technology, and then we describe an example of the innovative technologies that are actually required to achieve that goal. In particular, we present preliminary results about the attainable performance of large distributed arrays of antennas implemented as the ensemble of a few to many simpler sub-antennas of smaller sizes, carried by one (small) satellite each. The satellites that implement this radiating architecture need to be very close to each other and constitute a formation of flying objects, to be coordinated and controlled as a whole – a “Formation of Arrays”. We show how to take advantage of this new technology to improve network throughput in a multi-beam S-band mobile communication network with low-earth or geostationary orbiting satellites directly providing 5G-like communication services to low-cost, smartphone-like hand-held user terminals.
