NTT Tries Out WiGig for Industrial Private Networks

Why It Matters

The proof‑of‑concept shows WiGig can complement private cellular networks, offering a low‑latency, high‑throughput solution for large‑scale factory automation and remote inspection, accelerating industrial digital transformation.

Key Takeaways

• 60 GHz WiGig delivered 900 Mbps uplink over 2 km
• 18 repeaters enabled connectivity to robots and sensors
• 700‑km optical link provided 100 Gbps backhaul
• 0.1 s latency supported eight 4K video streams
• Shows WiGig can complement private cellular in factories

Pulse Analysis

Industrial sites are increasingly turning to private wireless networks to meet the data‑intensive demands of automation, robotics and real‑time monitoring. While private LTE and 5G have dominated recent deployments, unlicensed spectrum such as 60‑GHz WiGig offers a compelling alternative for dense, short‑range links that require ultra‑low latency. The high‑frequency band provides gigabit‑class speeds but traditionally struggled with range and obstruction, making NTT’s 2‑kilometre outdoor deployment a noteworthy breakthrough.

NTT’s demonstration combined a WiGig mesh with an all‑photonic network (APN) backbone, delivering 100 Gbps over a 700‑kilometre fiber link to Tokyo. This hybrid architecture enabled eight simultaneous 4K video streams from factory floor robots and sensors, maintaining a 0.1‑second round‑trip latency despite a 1,400‑kilometre round‑trip distance. Such performance opens the door for AI‑driven remote inspections, where high‑resolution video, audio and telemetry can be processed in central data centres, reducing on‑site labor and safety risks. The ability to keep connections stable on moving equipment further validates WiGig’s suitability for dynamic industrial environments.

The broader market reflects a shift toward diversified private wireless solutions. With 6,500 private cellular networks already supporting a $2.4 billion market that is projected to grow to $12 billion by 2030, operators and enterprises are evaluating the cost‑efficiency and spectrum availability of unlicensed technologies. WiGig’s low power footprint and rapid deployment can complement cellular coverage, especially in facilities where high‑capacity, low‑latency links are critical for real‑time AI analytics. As manufacturers seek to future‑proof their digital infrastructure, hybrid networks that blend licensed and unlicensed spectra are likely to become a strategic priority.
