Senior Researcher
Roger Pueyo Centelles is currently doing research on future military (battlefield communications for tactics, troops commanding, remote shooting, etc.) and civilian (aviation, emergencies, disaster relief, public broadband service, etc.)5G/6G satellite-based non-terrestrial networks (NTN) at the MWI-SDWN group. He received his Ph.D. in Computer Architecture by the Universitat Politècnica de Catalunya (UPC), where he also graduated as a Telecommunication Engineer. Previously, he worked with the Distributed System Group at UPC, and at the Guifi.net Foundation, on topics such as wireless mesh networking for embedded devices and IoT, dynamic routing protocols, distributed systems, edge computing and community networks.
