OPTI-6G key contributions at EuCNC & 6G Summit 2025 with Workshops and Poster Presentation
The OPTI-6G project marked a strong presence at the EuCNC & 6G Summit 2025, contributing to two high-impact workshops and a well-received poster session that showcased the project’s cutting-edge innovations in optical wireless communications and localisation.
Workshop 13: more details
Professor John Cosmas of Brunel University London, Technical Manager of OPTI-6G, chaired the Optics and Photonics Innovations Workshop (Workshop 13), which featured contributions from ten leading Horizon Europe SNS JU projects. The workshop underscored the pivotal role of photonics in shaping Europe’s future digital infrastructure, addressing topics such as autonomous photonic network management, reconfigurable optical transport, and photonics-based localisation.
It was delivered in two engaging sessions:
Session 1 – 14:00 – 15:30:
- SEASON: SElf-MAnaged Sustainable High-Capacity Optical Networks, Luis Velasco, UPC, ES
- FLEX-SCALE: Flexibly Scalable Energy Efficient Networking, Ioannis Tomkos, Univ. Patras, EL
- SUPERIOT: Truly Sustainable Printed Electronics-Based IoT Combining Optical and Radio Wireless Technologies, Tuomas Paso, Univ. Oulu, FI
- 6G-MUSICAL: Experimental verification of optical comb system and transceivers for 6G integrated sensing and communication (ISAC), Izzat Darwazeh, UCL, UK
- 6G-XCEL: AI for 6G Across Radio and Optical Networks, Dan Kilper, Trinity College Dublin, IE
Session 2 – 16:00 – 17:30:
- ECO-ENET: Efficient Confluent Edge Networks, Paolo Monti, Chalmers University of Technology, SWE
- 6G-EWOC: Optical Wireless in Support of a Computing-Communication Continuum for Connected Mobility, Bernhard Schrenk, Austrian Institute of Technology, AT
- PROTEUS-6G: Programmable Reconfigurable Optical Transport For Efficiently Offering Unconstrained Services In 6G, Ioannis Tomkos, Univ. Patras, EL
- OPTI-6G: Towards Optical 6G Cell Free Beamsteered Networks with Localisation, John Cosmas, Brunel University London, UK
- TERA6G: Photonics-enabled integrated THz transceivers with beamforming capabilities for 6G wireless networks, Eftasthios Andrianopoulos
The workshop successfully fostered collaboration, encouraged knowledge exchange, and sparked ideas for future partnerships in photonics for 6G. It significantly contributed to the shared European ambition of building sustainable, high-performance network infrastructure by 2030.
Workshop 10: more details
In parallel, Israel Koffman of RunEL, Israel, represented the consortium at the Workshop on Integrated Sensing and Communications (ISAC), participating in a panel focused on system-level improvements. His insights emphasised OPTI-6G’s role in enhancing 6G system architecture and performance through integrated sensing capabilities.
Complementing the workshop sessions, OPTI-6G also held a poster presentation, led by Prof. Cosmas, on “Cell-free Optical Wireless Integrated Sensing and Communication System Design and Test Plan.” The poster detailed the design and experimental framework for a 6G cell-free optical wireless communication network leveraging advanced localisation techniques—including Received Signal Strength (RSS), Time Difference of Arrival (TDoA), Angle of Arrival (AoA), and fingerprinting. The solution combines cell-free massive MIMO architecture with VCSEL-based OWC technology, promising improvements in coverage, throughput, and handover performance.
Poster Session:
The poster featured contributions from researchers across Europe, including Brunel University London (UK), Eurescom GmbH (DE), RunEL NGMT LTD (IL), OLEDCOMM SAS (FR), and Université de Versailles Saint-Quentin-en-Yvelines (FR).
Together, these activities highlighted OPTI-6G’s multidisciplinary impact and leadership in the advancement of sustainable, high-performance 6G optical networks.
