Technologies related to the environment and energy
02High-density optical fiber cable for aerial long-haul transmission
Optical fiber cable for aerial section with low-loss characteristics, small diameter, and reduced environmental impact

We exhibit a high-density optical fiber cable for aerial long-haul transmission with low-loss SMF suitable for long-distance and large-capacity transmission, towards economical construction of transmission systems over 400Gbps.

06Use case of low-latency FDN for smart agriculture
Easy remote strawberry harvesting with edge processing and quality stabilization

We have concluded a joint experiment with NTT AgriTechnology Corporation and demonstrated the feasibility of strawberry harvesting with a remotely controlled robot using low-latency FDN to control end-to-end service quality in real-time by integrating network latency and edge processing time. The developed system enables remote operation without stress by measuring network latency and processing time, and changing the arm speed of the robot on the basis of the service quality at that time. Here, we exibits and you can experience the developed system simulating the remote strawberry havesting.

07Enhanced drone applications with low-latency function dedicated network
Network supporting image processing enhances remote drone control

The utilization of drones is advancing across various industries, including inspection of public infrastructure, disaster response, and agriculture. By combining drones with low-latency and stable communication, as well as edge-based image processing environments within the network, smooth remote control is achieved. This enhances operational efficiency and increases the flexibility of use cases. This exhibit showcases promising future applications of remote drone operations and provides an overview of the supporting technologies.

09Optical fiber technologies contributing to advanced optical fiber network
Toward sustainable optical fiber network

The requirements for optical fiber network are becoming more diverse as the expansion of optical fiber communications. Our future optical fiber technologies to meet the demand for the performance and environmental requirements will be introduced.

10Ultra-Low Power, Compact Terminal with Power over Fiber
Sensing underground, underwater, and in remote areas without commercial power supply

We will introduce compact communication terminals that provide a communication environment for IoT sensors installed in off-grid areas (Remote areas, underground, etc.) and places where power lines are difficult to install.
In this exhibition, we will showcase terminals with ultra-low power consumption and sleep functions that reduce average power consumption and improve safety by incorporating all-solid-state batteries.

12Communication Frequency Control for High-efficiency Wireless Power Supply
Using communication radio waves for IoT energy

We introduce a high-efficiency wireless power supply that enables the deployment and management of many IoT devices. In the demonstration, we use a commercially available Wi-Fi access point to activate IoT devices by converting the communication radio waves into power. The demonstration shows the concept of our wireless power supply and the increase of generated power by using our communication frequency control technology. Various IoT services become feasible as we are freed from the battery maintenance of IoT devices and we can deploy and manage many IoT devices.

17Wireless-network control based on Intent extraction using generative AI
Providing wireless-network services that balance energy-saving and flexibility for the surrounding environment

By combining Wireless-network dynamic control technology(Cradio) and Intent extraction technology, we demonstrate the feasibility of flexible multi-wireless network control in accordance with user requirements more easily. The elemental technologies (Intent extraction, wireless control, wireless sensing) are also exhibited.

01Blockchain-based wireless access sharing technology
For sharing of all types of private wireless access, including Wi-Fi and private 5G

The exhibition will include a dynamic demonstration of the blockchain-based wireless access sharing technology using commercial Wi-Fi APs and smartphones, in contrast to the FY2023 exhibition which used a laptop. In addition, a static exhibition of an implementation using private 5G devices will also be presented.

06Camera Pose Estimation for 4D Infrastructure Management System
Identifying Facility Locations in Dashcam Images

The use of dash cams for infrastructure inspections has been expanding, in recent years. However, the dashcam inspections requires manual tasks, image-to facility linking, due to GPS positioning error. This exhibition demonstrates our technology that accurately identifies the location of facilities in dash came images. Inspection images with facilities location information can also be shared with other operators, reducing the overall inspection workload across social infrastructure.

07Optical fiber environmental monitoring for detection of road excavation construction
STOP Excavation Incident - The new service for infrastructure monitoring

We will introduce a use case of optical fiber environmental monitoring, i.e., road excavation detection. The novel technology aims to acquire a new social infrastructure monitoring business using optical fiber networks. The exhibition shows a system on the cloud that automatically detects and reports events without human intervention, which is expected to promote early introduction and develop new use cases.

08Infrastructure Asset Management Technology for Regional Microgrid Promotion
Realization of a decarbonized society through communication facilities that cooperate with social infrastructure

In recent years, social issues related to the environment and energy have been highlighted. This research will evaluate the applicability of telecommunication facilities to new social infrastructures (using regional micro-grids for energy supply, energy savings, etc.) to solve the above issues and realize low-cost facility construction.

09Non-stop inspection method for wind turbines using drones
Continuous wind turbine inspection to Increase power generation

Onshore and offshore wind power generation is drawing attention as one of the power sources that can increase domestic energy self-sufficiency.
The developed method aims to detect the presence of blade damage and motor abnormalities using drones without stopping the operation of wind turbines. With the this method, it will be possible to increase the amount of power generated by wind power and maintain it safely and efficiently.
There will be a static display of images and drones showing the demonstration experiment.
