Front-line Researchers
-
 Koji Muraki, Senior Distinguished Researcher, NTT Basic Research Laboratories
Abstract
In the field of condensed-matter physics, it is often the case that a theory about a phenomenon is experimentally verified 20 or 30 years after it was proposed. Koji Muraki, a senior distinguished researcher at NTT Basic Research Laboratories, and his co-researchers were the first in the world to experimentally observe a phenomenon similar to Andreev reflection, which occurs at the interface between a superconductor and normal metal, in a material other than a superconductor. This observation was achieved through research on a many-body effect, which is a phenomenon by which electrons acquire the properties that an individual electron does not possess by interacting with each other. We asked him about this achievement, research on the fractional quantum Hall effect (one of many-body effects) that led to this achievement, and his mindset as a researcher engaged in basic research.
Rising Researchers
- Shinobu Saito, Distinguished Researcher, NTT Computer and Data Science Laboratories
Abstract
The global information and technology services market for 2022 was reported to be 1.3 trillion U.S. dollars (about 150 trillion yen), and it’s been pointed out that the massive amount of software produced by this market demand, while bringing great value to our daily lives, has also led to a variety of problems. There are expectations that an approach that not only seeks to increase the amount of software (production) but to also reduce that amount (reduction) could help solve those problems. In this interview, we asked NTT Distinguished Researcher Shinobu Saito about his research on “Software Digital Twins.”
Feature Articles: Recent Developments in the IOWN Global Forum
- Latest Activities in the IOWN Global Forum
Abstract
With a view to creating a smart world, the concept of the Innovative Optical and Wireless Network (IOWN) aims to create a next-generation communication and computing infrastructure that features ultra-high capacity, ultra-low latency, and ultra-low power consumption. With input from global member companies, the IOWN Global Forum has been developing technical architectures and use cases and conducting proof of concept (PoC) activities and implementation verification. This article introduces the latest activities of the IOWN Global Forum, as well as the PoC Reference documents and reference-implementation-model documents that reflect the results of these efforts.
- Activities for Detailing the Architecture of the Open APN and Promoting Its Practical Application
Abstract
The IOWN Global Forum has proposed the Open All-Photonic Network (Open APN) as a network infrastructure that achieves low latency and low power consumption and issued an architecture document entitled “Open All-Photonic Network Functional Architecture,” in early 2022. This article introduces the activities carried out since the release of the above architecture document to detail the Open APN architecture and promote its practical application.
- Technical Study on IOWN for Mobile Networks
Abstract
The IOWN for Mobile Network Task Force has been investigating technical topics related to mobile and transport networks in the Innovative Optical and Wireless Network (IOWN), including the study of the key requirements for transport networks in the transition from the current 5th-generation mobile communications system (5G) to 6G, analysis of the gaps in technology hindering actualization of the uses cases aimed at by the IOWN Global Forum and proposal of solutions to them, and exploration of a future transport network architecture that leverages the All-Photonics Network and data-centric infrastructure. This article introduces the activities of this task force.
- IOWN Data Hub to Become a Reality
Abstract
The IOWN Global Forum is working on the social implementation of the Innovative Optical and Wireless Network (IOWN) technology. This article introduces the progress of the storage service study in the IOWN Global Forum, focusing on the newly published IOWN Data Hub Functional Architecture version 2.0 and the Proof of Concept Reference and NTT laboratories’ activities related to the IOWN Data Hub.
- DCI Architecture Promoted by the IOWN Global Forum
Abstract
The IOWN Global Forum has proposed an information and communication technology (ICT) infrastructure, called data-centric infrastructure (DCI), that leverages the high-speed and low-latency features of the Innovative Optical and Wireless Network All-Photonics Network (IOWN APN). This article describes the DCI on the basis of the Data-Centric Infrastructure Functional Architecture version 2.0 released by the forum in March 2023 and explains the advantages of the DCI in tackling challenges in scalability, performance, and power consumption that confront current ICT infrastructures. It is hoped that this article will help readers deepen their understanding of the DCI.
Global Standardization Activities
- Standardization Trends in IEEE 802.11be/bn
Abstract
We introduce the latest trends in the Institute of Electrical and Electronics Engineers (IEEE) 802.11be (11be), which will be the main standard of the next generation of wireless local area networks (LANs), and the IEEE 802.11bn (11bn), the following primary standard of 11be. The IEEE 802.11 standard is the most used unlicensed wireless LAN system globally, recognized as Wi-Fi. Wi-Fi is implemented in laptop computers and smartphones, Internet of Things devices, and home appliances. Its usage models also extend from consumer markets to business solutions such as industrial automation and intelligent agriculture in the 11bn era.
