Front-line Researchers

Hiroshi Yamaguchi, Senior Distinguished Researcher, NTT
Basic Research Laboratories▼OverviewAs optical communications continue to spread, the results of research on thephysical properties of light, electricity, and electrons to achieve high speed and low
power consumption of such communications are being put to practical use. New
physical phenomena have been discovered and explained by the interaction of thephysical properties of mechanical vibration and those of light, electricity, andelectrons. We asked Hiroshi Yamaguchi, a senior distinguished researcher at NTT
Basic Research Laboratories, who has produced several world-first results in regard
to applied technologies in the relatively new research field of nanomechanics, about
his research activities and his attitude as a researcher.

Optimization of Entire Urban Areas Using IOWN
▼Abstract
NTT is advancing the Innovative Optical and Wireless
Network (IOWN), NTT’s vision of creating a smart worldusing innovative technologies. The aim is to accelerate
digital transformation in collaboration with its partners
and solve social problems. This article introduces NTT’s
activities to optimize urban areas with a focus on
mobility and how it can be used to address current
social problems. Essentially, this will be done byachieving both individual/local and group/global
optimization on the basis of various types of information
using IOWN and other technologies and assets of theNTT Group.

Developing Smart Infrastructure Platform Based on theSmart Infra Business Concept▼Abstract
This article introduces the Smart Infra Business Concept
promoted by NTT Infrastructure Network Corporation(NTT InfraNet) for using information and communication
technology to smartly implement maintenance andmanagement work related to the telecommunication
infrastructure facilities (such as utility poles andmanholes) of the NTT Group. This concept is not limited
to the NTT Group’s digital transformation but also forms
the basis of the Smart Infra Platform to be implemented
to solve problems faced by social-infrastructurecompanies. Three use cases for using the Smart Infra
Platform are also introduced.
