As a future image of access networks in the IOWN era, wireless access, optical-wiring/optical-access, and maintenance operations technology will be introduced, and the role of access technology will be explained through video. We will continue working together to realize our access-network concept in the near future.
To address the changing demands in the IOWN/6G era, we will construct and operate a testbed at the Tsukuba Access Network Research Laboratory. This will enable integrated research and development as well as demonstration experiments, thereby accelerating the implementation of advanced network technologies.
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.
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.
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.
NTT aims to expand the service area of mobile communications using satellite and HAPS communications in the Beyond 5G/6G era. However, it is difficult to achieve high transmission speeds with satellite and HAPS over long distances, and the transmission speed fluctuates due to weather conditions. In order to provide high quality services to customers in such environments, we are considering the following technologies over three stages (short term: dynamic traffic control in disaster response wireless systems, medium term: communication priority control, long term: communication route control), and this exhibition will introduce the short-term and medium-term initiatives.
While a high-frequency wireless band can enable large capacity wireless communication, it requires handover because transmission quality is affected by shielding and huge transmission loss. We developed and evaluated a dynamic site-diversity technique using multiple radio unit to avoid interruption caused by handover. This exhibition shows how the product version of the 60-GHz wireless LAN (WiGig) device supports the technique.
We introduce and present the latest status of multi-radio proactive control technologies (Cradio®). In addition to the current functions and examples of their use, we will also present the status of future functions with demonstrations.
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.
Assuming a 40-GHz band distributed MIMO system in which base station antennas are distributed, this exhibition presents a technique in which a beam search is performed on all antennas simultaneously. This makes it possible to quickly detect the optimal combination of antennas and beams for multiple wireless terminals even in a high-speed moving and shielded environment.
A static exhibition of a 40-GHz band distributed MIMO testbed system combining A-RoF will be held at Tsukuba Research Laboratories.

The spread of services using mobile lines and data centers (DCs) and the future spread of IOWN services requires the rapid isolation and restoration of faulty sections in the event of a large-scale disaster or failure. Our development promotes remote-operated optical-fiber node technology that constantly monitors lines from a remote location and instantly isolates the faulty section in the event of a line failure.
Efficient and accurate recovery from large-scale network faults requires a variety of data, including multiple network infrastructures, network alerts, and operational procedure manuals.
This showcase highlights our AI technologies for zero-touch troubleshooting, one-stop integration of remote and on-site operations, and extending the application to in-house network management.
This section introduces an AI that generates images of equipment to predict the progression of deterioration several years later from images taken of road bridges. This AI can predict the change over time of corrosion on steel parts of road bridges based on image data learned in advance and environmental information (temperature, precipitation, etc.) of the installation site and generate images showing the progression of corrosion. By utilizing this AI, the frequency of inspections, which are currently conducted at regular intervals, can be reviewed, repair plans can be optimized, and maintenance costs can be reduced.
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.
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.
