This verification test, which will be conducted from December 1, 2022 to March 17, 2023, was selected by Japan's Ministry of Internal Affairs and Communications as one of its "Development Demonstrations aimed at achieving local challenge-solving 5G in 2022."

The trial will involve using a robot equipped with a 4K camera to capture video data from data center equipment, including servers. This data will be transmitted locally via private 5G, and a system will be established to analyze on-site conditions using AI to detect any anomalies at an early stage. Fujitsu aims to create a system that can support on-site condition monitoring and recovery efforts, even from a remote location, in the event of a disaster or emergency, by fully leveraging the high-speed transmission capabilities of private 5G technology. This
robust disaster management approach will ensure data centers are resilient and support the digital society.

As the digitization of society accelerates and the amount of distributed data rapidly increases, data centers that store and process vast amounts of data are becoming a core part of the infrastructure supporting the digital society of the 21st century. Highlighting this growing importance, the Japanese government's vision of a "Nation of Digital Garden Cities" calls for the establishment of regional data center facilities with a view to mitigating the risks posed by disasters and other vulnerabilities stemming from data center centralization. As the importance of regional data centers continues to grow, their number is expected to increase rapidly in the future.

The key to stable data center operations lies in high-quality maintenance and inspection, along with rapid recovery in the event of a disaster or other emergency. However, the shrinking workforce and the difficulty in recruiting talent remain challenges in many parts of Japan, with this shortage particularly acute in rural areas. Maintaining and improving the quality of inspections with limited staff and reducing workloads are urgent issues for data center operators.


Essay outline

fujitsu-figure-1Fujitsu will build a private 5G environment at its data center in Yokohama City, Kanagawa Prefecture, and will test the effectiveness of autonomous robots equipped with 4K cameras to patrol equipment and facilities, perform early detection of anomalies, and provide remote assistance to field workers in case of failure.


A robot equipped with a 4K camera performs unmanned patrol monitoring to detect anomalies in the operating status of server equipment (LED lamp illumination status) and quickly notifies the operator via the private 5G network in case of any anomalies. It provides
remote assistance for system recovery work through video and audio transmission over the private 5G network.
It also detects and blocks unauthorized communications in data centers handling highly sensitive data.

fujitsu-figure-2Technical Study on the Propagation Characteristics of Private 5G Radio Waves (Technical Demonstration)
A flexible area construction method using a DAS antenna (1) will be used to build a private 5G area network in a server room with a low ceiling and many high barriers, and in an electrical room with high-voltage cables laid on the ceiling, and the effects of radio wave propagation will be measured.
Radio propagation measurement and performance evaluation (4.8~4.9 GHz indoor band)
Refining the calculation formula parameters specified in the area calculation method specified in the examination standards related to the current Radio Law, contributing to the efficiency of area design in the development of other sites.
