From June 3 to 6, i2CAT actively participated in the 2025 edition of the EuCNC & 6G Summit, held in Poznan, Poland. As one of Europe’s most important conferences on advanced communications, the event brought together leading global researchers, industry experts, and policymakers to shape the future of Beyond 5G and 6G systems.
Throughout the week, i2CAT researchers shared cutting-edge contributions through tutorials, paper presentations, special sessions, and live demonstrations, representing several Horizon Europe flagship projects, including 6G-XR, COGNIFOG, INSTINCT, iTrust6G, NANCY, and BeGREEN.
Hatim Chergui during its intervention
On Tuesday, Hatim Chergui delivered a tutorial on “Explainable AI for Communications and Networking” on behalf of the COGNIFOG project, offering an in-depth look at how XAI techniques contribute to transparency in autonomous network management. On the same day, Daniel Camps contributed to a workshop on 6G experimentation, presenting how the 6G-XR project enables third-party access to 6G testing through CAMARA APIs and novel orchestration tools. Shuaib Siddiqui participated in the “6G Trustworthiness” workshop, presenting advanced approaches to remote attestation in dynamic systems, highlighting progress from the iTrust6G project.
On Wednesday, Xavier Costa-Pérez took part in a special session on Integrated Sensing and Communication (ISAC), sharing the vision of the BeGREEN project for the convergence of sensing and communication capabilities. Later that day, Juan Sebastián Camargo presented a paper on autonomous resource allocation for 6G network slices, merging work from the NANCY and COGNIFOG projects.
On Friday, researcher Maxime Compastié presented a joint paper co-authored by multiple i2CAT experts, proposing a Zero-Knowledge Proof-based framework for secure inter-slice communication—an output of the UNICO 6GENABLERS, COGNIFOG, and iTrust6G projects.
Throughout the exhibition, i2CAT showcased a range of interactive demonstrations that reflected the centre’s multidisciplinary approach to 6G innovation. At the INSTINCT booth, Andra Blaga presented a hybrid GNSS and 5G-NR localization system designed to improve positioning accuracy in environments where satellite signals are degraded. Meanwhile, at the 6G-XR booth, researchers Amr Abdelnabbi and Marc Martos unveiled a congestion-aware holographic communication system, demonstrating how real-time telemetry and adaptive bitrate control can sustain immersive XR experiences even under challenging network conditions.
iTrust6G Demonstrations
At the SNS Joint Sustainability booth, Miguel Catalan-Cid introduced the BeGREEN Intelligence Plane—an AI-powered orchestration system for energy-efficient O-RAN management that automates cell activity optimization through a combination of rApps, xApps, and AI algorithms. Simultaneously, the SNS Joint Trustworthiness and Security booth hosted Maxime Compastié and Shuaib Siddiqui, who presented two demonstrations developed within the iTrust6G project. The first focused on risk-aware, cyber threat intelligence-enabled remediation in multi-domain environments, while the second showcased a policy-based trust evaluation mechanism for securing cross-domain service interactions.
At the 5GSmartFact booth, i2CAT researchers Marisa Catalan, Suneel Kumar, Daniel Camps, and Sanjha Khan participated in the final event of the 5GSmartFact project—an Industrial Doctorate Training Network involving 14 PhD fellows. The booth served as a key platform to disseminate and demonstrate the final results of these research efforts, targeting emerging technologies poised to transform the connected and automated industry of the future. Visitors, including industry stakeholders and policymakers, explored results in time-sensitive networking over wireless, visible light communications, massive MIMO, network slicing, intelligent radio environments, and multi-modal localization. Demonstrations included applications such as cooperative 5G-enabled robot localization, AI-driven slicing orchestration, and 3D object detection in mobile robot platforms. PhD fellows guided attendees through the results and testbeds, underscoring strong academic-industry collaboration with partners like NEC, Bosch, Ingeniarius, and Roboception.
5GSmartFact Final Event
i2CAT’s active involvement in EuCNC & 6G Summit 2025 reinforced the centre’s commitment to collaborative, multidisciplinary research and innovation. From AI-powered orchestration to trusted systems and sustainable networking, i2CAT continues to lead and support the evolution of the 6G ecosystem—helping to shape a more connected, intelligent, and secure digital future.
