6G-SANDBOX

The MR@REAM system was successfully validated under real-world conditions. Key achievements included:

• Reliable real-time communication between MR and PC, maintaining low-latency video/audio streaming at optimised configurations (60–70% quality, 1920x1080 resolution, ~20 Mbps).
• High responsiveness of the control system, with scenario updates and UI changes reflected instantly on both sides.
• Bi-directional voice communication remained stable and clear when bandwidth demands were controlled, especially with prioritisation of audio in lower bitrate settings.
• Flexible encoder controls allowed fine-tuning of stream settings (FPS, resolution, quality), enabling adaptive performance testing.
• PC operator tools, such as network monitoring, timers, and UI interactions, empowered remote participants to supervise and assist effectively.
• Infrastructure readiness, thanks to the integration with 6G-SANDBOX testbed, 5G CPE devices, and the Amarisoft-based SA core, which provided a robust and modern networking layer.

Despite the high performance, limitations appeared when pushing video quality beyond 80%, resulting in audio packet loss and slight UI desynchronisation. These limitations were valuable for identifying future optimisation paths such as adaptive streaming, bandwidth-aware prioritisation, and further MR-side performance tuning.
