Thomas Heyn received his degree in Electrical Engineering (Dipl.Ing.) from Friedrich-Alexander-University in Erlangen in 1996 and joined Fraunhofer IIS shortly after. He implemented wireless communication standards for satellite and terrestrial applications using Software-Defined Radio platforms and carried out field trials for performance assessments and propagation channel modelling. Since 2001, he is head of the Mobile Communications Group within the Communication Systems Division. His current research interests include evolutions of 5G-Advanced and 6G, investigating technologies like integrated satellite/terrestrial 3D-networks, V2X communication and network energy saving. As a 3GPP delegate since 2015, he was one of the first to integrate satellites into 5G. Furthermore, Thomas Heyn and his team demonstrate latest 5G standards based on the open source stack OpenAirInterface.
