This whitepaper presents the results and lessons from FIDAL Work Package #6 on large-scale trials across public-safety communication and user media Use Cases (UC), showing how emerging  Beyond 5G capabilities can support immersive interaction, mission-critical communications, remote expertise, edge-assisted XR/AR, live media production, networked music performance, and multi-site community engagement. The trials collectively demonstrate that Beyond 5G can enable meaningful new services when combined with network applications, edge/cloud resources, slicing, and application-specific media handling.
