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.
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.
Promoting DX in factories requires a stable wireless and optical network environment with low latency, large capacity, and various equipment. In this exhibition, we will introduce a visualization function that enables you to check the communication status at a glance and a path switching function that enables efficient network use on the basis of the application, enabled by the real-time cooperation between Cradio® for radio control and low-latency FDN for optical control.
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.
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.
Using technologies cultivated in communications, we are researching and developing technologies to realize proactive responses to large-scale earthquakes and intensifying torrential rain disasters by predicting damage to infrastructure facilities such as water supply and roads. In this article, we will introduce a visual image of road damage prediction.
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.
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.
