EuCNC & 6G Summit 2025: Spotlight on Immersive Connectivity and Experimentation
From real-time holograms to remote industrial collaboration, the 6G-XR project brought its vision of next-generation immersive communication to life at EuCNC & 6G Summit 2025, held in Poznań, Poland, from 3–6 June 2025. Through live demonstrations, expert and poster presentations, and specialised workshops, 6G-XR highlighted how emerging 6G infrastructures can support the demanding performance requirements of extended reality (XR) applications.
Demonstrating Reliable Holographic Communication
One of the standout moments came at the 6G-XR booth, where Amr Abdelnabbi and Daniel Ortiz from i2CAT led a hands-on demo on reliable holographic communications using congestion-aware network APIs. The demonstration illustrated how 6G-XR technologies can preserve immersive experiences even in congested mobile environments—offering a window into the future of real-time XR services.
At the heart of the demo were three technology enablers:
- A Congestion Detection Function (CDF), capable of monitoring cell-level telemetry to flag potential service degradation.
- A Network-Aware Control Plane, which dynamically adapts the bitrate of a holographic session based on real-time congestion signals.
- An End-to-End Holographic Communication Platform, which orchestrates the full pipeline for immersive content delivery, integrating capture, transmission, and rendering across the network.
for reliable holographic communication technology
This architecture not only helps sustain quality of experience for XR users but also opens new possibilities for Mobile Network Operators (MNOs). By exposing these functions via open Network-as-a-Service (NaaS) APIs—such as those from the CAMARA initiative—operators can enable smarter, more responsive services for third-party XR developers.
What visitors saw at the booth:
- Two XR users engaged in a live holographic call.
- Congestion was introduced by an eMBB user in the same 5G cell.
- Without intervention, the XR session degraded noticeably.
- Once the CDF activated, the system adjusted the stream bitrate, stabilising the experience.
- When the congestion cleared, the session returned to full resolution.
Sharing 6G Experimental Experience
6G-XR also contributed to a collaborative workshop on 6G experimentation methodologies, held on 3 June 2025. The session gathered insights from several SNS JU projects—6G-SANDBOX, CONVERGE, SUNRISE-6G, ORIGAMI, EXIGENCE, TRIALSNET, FIDAL, and others—to share practical lessons learned from real-world testbeds and lab experiments.
Daniel Camps (i2CAT), leader of 6G-XR’s WP4, presented the talk “Exposing CAMARA APIs for Third-Party Experimentation in 6G Test Facilities – The 6G-XR Approach”. His presentation focused on how XR developers can test adaptive services in programmable 6G environments, highlighting the importance of well-calibrated experimental design, performance measurement, and reproducibility.
XR Meets Smart Manufacturing
On the final day of the summit (6 June 2025), Kenichi Komatsu from the University of Oulu shared research on XR and digital twins in the session “Experiments and Testbeds for 5G/6G Networks.” His presentation, “Addressing 3D Digital Twin in XR Remote Fab Lab over Sliced 5G Networks,” introduced a blueprint for immersive collaboration in remote fabrication labs.
Developed in collaboration with Finwe Ltd., Kaitotek Oy, Allbesmart Lda, and CWC Oulu, the approach leverages network slicing and ultra-reliable low-latency communications (URLLC) within an Open RAN-based 5G environment. A live experiment showed how XR-driven interaction with digital replicas of physical equipment could be sustained across eMBB and URLLC slices—even under congestion.
User feedback confirmed the technical findings: a high-quality, low-latency experience that opens the door to distributed R&D and smart manufacturing scenarios.
Poster Booth: Showcasing Open Call Results
In addition to the live demo, 6G-XR hosted a poster booth featuring results from Open Call 1 and 2. The booth highlighted innovative solutions and experimentation outcomes contributed by third-party projects integrated into the 6G-XR ecosystem. These experiments spanned a range of XR applications and validated how open APIs and programmable testbeds can accelerate XR service innovation in real-world conditions.
Moving Forward
6G-XR’s participation in EuCNC & 6G Summit 2025 demonstrated how intelligent, adaptive networks can unlock the full potential of immersive applications. From congestion-aware holography and open experimentation APIs to remote industrial collaboration, the project continues to chart new territory in the evolving landscape of XR and 6G.
