At the European Wireless 2023, 2nd – 4th October in Rome, Prof. Symeon Chatzinotas, from the University of Luxembourg participated and gave a keynote talk on the topic “Mega Constellations – Trends, Technologies and Vision”.

Prof. Chatzinotas’ keynote focused on large LEO constellations and multi-orbit satellite systems have recently emerged as complex network architectures that provide and enhance a range of satellite services e.g. ubiquitous broadband internet, direct to handheld, satellite IoT etc. The current talk reviews the current capabilities of such systems from a communication perspective and describes the challenges of applying key technological enablers in space. In addition, we present a vision about future research topics of long-term importance in the area of Satellite Communications and Non-Terrestrial Networks.
