TERRAMETA Project

Our first measurement campaign yielded remarkable outcomes, and we are pleased to present them! 🚀🚀   In this article, we first present and characterize three RIS prototypes with 100×100 unit cells of half-wavelength inter-cell spacing, which were optimized to offer a specific non-specular reflection with 1-, 2-, and 3-bit phase quantization at 304 GHz. The designed static RISs were considered in an indoor channel measurement campaign carried out with a 304 GHz channel sounder. Channel measurements for two setups, one focusing on the transmitter-RIS-receiver path gain and the other on the angular spread of multipath components, are presented and compared with both state-of-the-art theoretical models as well as full-wave simulation results.   The article concludes with a list of challenges and research directions for RIS design and modeling of RIS-parameterized channels at THz frequencies.   We invite you to read the full article (to be published soon): "Characterization of Indoor RIS-Assisted Channels at 304 GHz: Experimental Measurements, Challenges, and Future Directions" https://lnkd.in/djj9KPnq   George Alexandropoulos, bo kum jung, Panagiotis Gavriilidis, Sérgio Matos, Lorenz Löser, Varvara Elesina, Antonio Clemente, Raffaele D'Errico, Luis Pessoa, Thomas Kürner   #TERRAMETA #6G #6GSNS #SNSJU #HorizonEurope

On November 29, the three Horizon Europe and 6G SNS projects 6G-SHINE project, SUPERIOT, and TERRAMETA Project have joined forces to offer a joint free webinar on a shared topic: Sustainable Wireless Design. The online session was led by three speakers who delivered invited talks. Meng Li, imec (6G-SHINE), delivered a compelling presentation on the analysis of sub-THz transceiver architecture power requirements for XR indoor gaming. Yasser Qaragoez, KU Leuven (SUPERIOT), shared insights on the use of biased-FSK modulation for efficient SWIPT in sustainable IoT. Luis Pessoa, INESC TEC (TERRAMETA), made a strong case for the sustainability of reconfigurable intelligent surface-based networks. The session concluded with an open discussion. We would like to thank the speakers for their contributions! 👏👏 You can watch the video of this session here: 🔗 https://lnkd.in/d4ptNsnc George Alexandropoulos #SNSJU #6GSNS #TERRAMETA #SUPERIOT #6Gshine

Special Session organized by TERRAMETA Project, TIMES 6G, and 6G-SHINE project at IEEE CSCN, 25–27 November 2024, Belgrade, Serbia   The Special Session entitled “Key enablers for integrated sensing and communications in industrial environments” was jointly organized by TERRAMETA, TIMES, and 6G-SHINE, and addressed overlapping topics in the context of the three SNS JU Phase I projects.   The session featured two invited talks: “Integrated Sensing and Communications in 6G: a standardization outlook” by Mario Castaneda (Huawei, Germany) and “Architectural landscape for ISAC enablement in 6G” by Filipe Conceição (InterDigital, UK).   Dr. Praveen Naidu VUMMADISETTY (University of Luxembourg, Luxembourg) and Konstantinos Manolakis (Nokia, Germany) joined the panel discussion moderated by Malte Schellmann (Huawei, Germany).   It was a very engaging session, with participants from diverse backgrounds including industry, academia, and standardization, providing unique insights and perspectives, enhanced by pertinent questions from the audience.   https://lnkd.in/dcB8wP4E   Luis Pessoa George Alexandropoulos   #SNSJU #6GSNS #CSCN24 #TERRAMETA #Times6G #6gshine

TERRAMETA organized the symposium EP02 "Memristor devices from theory to system level integration for next generation of computation and communication" at the B-MRS Meeting 2024 in Santos, Brazil. High-level invited talks were given by Valeria Bragalia (IBM Zürich, Switzerland), Stephan Menzel (Forchungszentrum Jülich, Germany), Hannes Raebiger (Yokohama National University, Japan) and Vítor Tavares (INESC TEC, Porto, Portugal). The symposium was moderated by Dr. Jonas Deuermeier from NOVA University Lisbon and Prof. Vítor Tavares presented results from the TERRAMETA Project. 🔗 https://lnkd.in/dDhXZdJ8 Luis Pessoa George Alexandropoulos Emanuel Carlos Asal Kiazadeh #TERRAMETA #6G #6GSNS #SNSJU #HorizonEurope

TERRAMETA at the Hexa-X-II SNS ISAC Workshop 👏👏   TERRAMETA together with several other SNS projects participated in the Hexa-X-II SNS ISAC Workshop "Online workshop on integrated sensing and communication towards 6G" on October 8th. Prof. George Alexandropoulos gave a presentation about "THz multi-functional RISs and ISAC" highlighting the main achievements of the TERRAMETA Project up to date and moderated the workshop’s one-hour panel.   You are welcome to watch the video of this presentation! We hope you enjoy it!   🎬 Video: https://lnkd.in/dvaiVM4P 🔗 Hexa-X-II SNS ISAC Workshop: https://lnkd.in/dGTCBh7F #TERRAMETA #6G #6GSNS #SNSJU #HorizonEurope Luis Pessoa George Alexandropoulos

TERRAMETA at #EuMW2024! 🚀🚀   We had an incredible time at #EuMW2024, where innovation met enthusiasm!   The TERRAMETA demo showed a scenario applicable to mobile robots in a factory environment with real-time 3D reconstruction of the surroundings. It featured a baseband unit developed by Intracom Telecom with a baseband bandwidth of 2 GHz, a D-band transceiver operating at 145 GHz with a bandwidth up to 17 GHz, and active RISs capable of handling NLOS scenarios, both developed by CEA-Leti, among other components.   We invite you to watch our demo and witness TERRAMETA in action - we hope you enjoy it!   Special thanks to our partners at CEA-Leti, Intracom Telecom, and Dell Technologies for their contributions in making this demo possible! #TERRAMETA #6G #6GSNS #SNSJU #HorizonEurope Luis Pessoa George Alexandropoulos

TERRAMETA Project held another successful face-to-face meeting in Cork, Ireland, on June 25th and 26th. The strong collaboration and insightful discussions between the partners were truly remarkable, especially for this meeting which marked the halfway point of the project. We are pleased to have participated in this very productive meeting! Many thanks to Sean Ahearne for organizing the venue at Dell Technologies! #TERRAMETA #6G #6GSNS #SNSJU #HorizonEurope Luis Pessoa George Alexandropoulos

Great achievement early in the project with many more to come!
