6G-EWOC @ ECOC in Copenhagen
October 2025
6G-EWOC has been well-represented at ECOC 2025, Europe’s largest conference on optical telecommunications. Three contributed papers were presented by Florian Honz and Bernhard Schrenk from AIT, including hybrid radio / free-space optical communication using a shared-aperture air interface, beamforming assisted optical wireless communication between a mobile user and an optical hotspot, and the adoption of wavelength division multiplexing in visible-light communication, where white and thus colorless light-emitting diodes serve as data emitter. Besides the presentation of scientific papers, Bifrost Communications showcased its quasi-coherent transceiver pluggables in its exhibition booth, demonstrating high-speed fiber-optic communication through highly simplified coherent optics.

Strong presence at ICTON 2025
July 2025
Several 6G-EWOC researchers were attending this year’s anniversary edition of the ICTON conference in Barcelona, where our project-related findings were reported through three invited and two contributed papers.
J.A. Lazaro from UPC presented the 6G-EWOC test-bed and work on a digital twin for 5G networks, as well as RaDAR to RaDAR communications to support integrated sensing and communication.
J.M. Ramirez from III-V Lab discussed strategies for and challenges related to heterogeneous photonics integrated circuits, highlighting the quasi-coherent receiver of 6G-EWOC.
An in-depth discussion on the system-level performance for quasi-coherent reception was provided by J.A. Altabas from Bifrost Communications, who presented results towards metro, access and fronthaul networks.
Finally, B. Schrenk from AIT shed some light on 6G-EWOC’s recent advances on beamforming-assisted free-space optical Fi-Wi-Fi links.
After a short summer break, we’ll be back at the ECOC conference in Copenhagen to present further results deriving from 6G-EWOC.
6G-EWOC at EuCNC / 6G Summit 2025
June 2025
Clustering activities among 6G research projects is essential to disseminate own findings and to cross-pollinate across research initiatives. Towards that ambition, 6G-EWOC contributed to the European Conference on Networks and Communications in Poznan, Poland.
Our researchers contributed to two workshops. José Antonio Lázaro from UPC delivered a talk on how to implement a comprehensive approach to verify key performance indicators across multiple demonstrators at the “6G experimentation methodologies, pitfalls and best practices” workshop. In addition, Bernhard Schrenk from AIT participated in the “Optics and Photonics Innovations” workshop where he presented the project findings towards optical wireless in support of a computing-communication continuum, including I2I fronthaul and V2I / V2V optical access technologies.
Besides delivering our view, EuCNC, which is recognized as the European 6G Summit, provided us with a great opportunity to network with our partner projects. We look forward for the next EuCNC / 6G-Summit and its exhibition.
6G-EWOC at ICMLCN 2025
May 2025
6G-EWOC contributed two-fold to the International Conference on Machine Learning for Communication and Networking, which took place in Barcelona in May 2025. This conference addresses the challenges that reside when deploying 6G networks that require an efficient orchestration and control of all resources deployed at their physical-layer infrastructure.
José A. Lázaro from UPC introduced quantum machine learning to facilitate network intrusion detection in software-defined networks, to monitor and analyze network traffic in an efficient manner for ultimately enabling the identification of malicious activities or policy violations.
Moreover, Josep M. Fàbrega and Ricardo Martínez from CTTC organized a special session on AI/ML for Optical Networks and Communications.
To Brave all Turbulences: 6G-EWOC’s Fi-Wi-Fi Bridge Receives Top-Score at OFC 2025
April 2025
In a contributed paper that has been top-scored (i.e., ranked within the top-10% of all accepted papers) and presented at OFC, 6G-EWOC’s researchers demonstrate the mitigation of optical turbulence – an atmospheric effect that spoils optical free-space communications if left unaddressed. AIT’s team uses a very simplistic diversity scheme that can be smoothly integrated with the 91-element focal plane array beamformer that further simplifies the initial alignment of the Fi-Wi-Fi bridge. The paper has been presented together with another oral paper on VLC.
With over 16,000 registrants from 80+ countries, a showcase of more than 600 exhibiting global companies and more than 750 papers, OFC is the world’s largest conference on optical telecommunications.

On the Showfloor: 6G-EWOC @ Mobile World Congress 2025
March 2025
The UPC stand at MWC 2025 showcased innovative research in 6G, AI, and edge computing. Over four days, pioneering prototypes like the 6G-EWOC technology connected academia and industry.
A real-time demo combined MIMO FMCW radar and camera data. While the radar estimated object distances but misclassified types, the camera recognized people yet couldn’t determine distance. The multimodal fusion technology corrected these gaps, associating distances with people and filtering out non-human objects.
But 6G-EWOC showed how intermediate-level fusion improves average precision and collaborative perception combines vehicular sensors at different viewpoints overcoming occlusions, with edge computing and OWC as vital enablers. The presentation concluded with videos showcasing improvements in detection accuracy for Connected Autonomous Vehicles, using both synthetic and real-world datasets, highlighting the transformative potential of these technologies. High-level representatives of 6G-SNS attended the presentation.
Recap: 6G-EWOC @ Fall Conferences
October 2025
The 6G-EWOC team was indeed very active this fall. We attended several conferences in the field to disseminate the concept behind our architecture and first experimental results on the development of its constituents.
At the IEEE Future Networks World Forum 2024, we contributed to the symposia on Connected and Automated Mobility and Optical-Wireless Convergence. We presented the implications concerning the introduction of low-latency simultaneous mapping and localization of traffic participants to 6G networks and our approach in accomplishing this challenge – together with optical wireless comms as the bandwidth enabler that permits a late and thus more effective fusion of raw sensor data at the network edge.
At the IEEE CAMAD 2024 and Infocom World 2024 conferences, we had the chance to focus on the architectural aspects that arise when addressing a new vertical through the introduction of a next-generation radio network. With the influx of new sensor and heterogeneous access technologies, the network needs to cater for their perculiarities in order to unleash their full potential.

From Fiber to Fiber: How Fi-Wi-Fi Extends Optical High-Capacity Networks
September 2025
6G-EWOC attended the ECOC 2024 conference to present its novel approach to bridge gaps in its high-capacity fiber infrastructure through its Infrastructure-to-Infrastructure (I2I) optical wireless communication mode.
In this top-scored paper, we demonstrate the efficient coupling between two single-mode fibers, as thin as a human hair, over a distance of 63 meters. We do so by utilizing a beamformer that is inspired by a simple photonic lantern.
