📶 Telecom: KDDI Achieves World-First Real-Time Holographic Transmission
KDDI Research has announced a successful verification experiment in January 2026 for real-time transmission of holographic 3D video, spatial audio, and haptic (force feedback) data over a network, marking a significant milestone in immersive communication technologies. According to the Tech Note published by KDDI, this demonstration combined multiple sensory modalities in synchronization for the first time, showcasing a richer communication experience beyond conventional video and audio.
In the experiment, KDDI Research used a volumetric studio setup to capture a subject as a full 3D holographic image. The raw holographic data, inherently much larger than traditional video due to the inclusion of phase information as well as amplitude, was compressed using a proprietary technique developed by researchers that dramatically reduces data volume without degrading perceived quality. This compression enables real-time transmission over current networking environments.

At the receiving end, the system reconstructed the holographic data and delivered it alongside synchronized spatial audio and haptic feedback through a dedicated playback setup, allowing observers to see, hear, and feel the presence of the remote subject. This “multi-modal” communication demonstrates the potential for future applications in remote collaboration, education, entertainment, and training where rich sensory interaction is critical.

The success of this experiment reflects KDDI’s broader strategy of developing technologies for Beyond 5G/6G and immersive networking, which aims to integrate advanced sensory data transport into future communication infrastructures. It builds on KDDI’s ongoing work to enhance AI-driven network operation and autonomous system control, as well as collaborative research into AI and next-generation wireless technologies with partners like Samsung Electronics.
By demonstrating real-time holographic transmission with full sensory synchronization, KDDI positions itself at the forefront of next-generation XR (extended reality) communication research, with implications for how future networks will support rich interactive experiences across industries.
