To help create a more affluent and harmonious society, it offers various services for transforming business using digital technology and solving social issues. We talked with Yutaka Sasaki, president and chief executive officer of NTT DATA Group Corporation, about the business strategy of NTT DATA under the new organizational structure and his aspirations for the new fiscal year.
Front-line Researchers
- Wataru Yamada, Senior Distinguished Researcher, NTT Access Network Service Systems Laboratories
Abstract
Used for mobile communications and other purposes, radio waves are a limited resource, and their frequencies are allocated and registered globally according to the intended use by the International Telecommunication Union - Radiocommunication Sector (ITU-R). The frequencies allocated are then regulated and used in each country. The number and types of services using radio waves, including wireless mobile communications, have been rapidly increasing. Although technological advances have enabled new frequency bands to be explored and allocated, radio-frequency resources continue to be scarce, and resolving this issue has become urgent to address the increasing use of radio waves in the future. Wataru Yamada, a senior distinguished researcher at NTT Access Network Service Systems Laboratories, is striving to effectively use available frequencies and explore new frequency bands by developing the real-time wireless-quality-estimation platform, which applies quantum annealing and other technologies to radio-wave propagation. We spoke with him about his approach to overcoming the limits on radio resources, research style, and passion for continuing to take up new challenges.
Rising Researchers
- Masaaki Nishino, Distinguished Researcher, NTT Communication Science Laboratories
Abstract
In recent years, the increase in communication speeds has accelerated the development and use of applications that process large amounts of data. This has led to a growing collective need for high-speed, large-volume data processing. In response to such collective challenges, we spoke with Distinguished Researcher Masaaki Nishino, who is researching algorithms that compress and process data according to patterns to make data processing faster and more efficient.

- 5G Throughput-prediction Technology for 28-GHz Channels Using Physical-space Information
Abstract
Advances in wireless communications, such as the 5th-generation mobile communication system (5G), have enabled a wide variety of devices to be connected to wireless networks. In 6G, all physical entities will be connected to wireless networks, and their physical-space information, such as position and velocity, will be available for new mobile services. NTT’s Innovative Optical and Wireless Network (IOWN) will accelerate to obtain the physical-space information from various sensors. Therefore, mobile traffic is growing rapidly toward 6G. The use of the millimeter-wave (mmWave) bands is promising to increase the capacity of mobile networks. However, the mmWave link quality (LQ) is strongly affected by surrounding objects. To stably use mmWave bands, an effective solution is to predict future LQ and adaptively control wireless communication. This article introduces 5G throughput-prediction technology that is based on deep neural networks using physical-space information and an automated 5G measurement environment using humanoid robots for deep-learning evaluations.
