Because of more than 10 years effort, FTTH has become

the most popular Broadband service in Japan.


The ICT sector, including FTTH, should keep lower emissions of CO2, and

expected to help reducing emissions of other sectors.

FTTH should saves energy by becoming more energy efficient,

and should reduce CO2 emissions of society by utilizing itself efficiently.

Identification by human

Identification by system

NTT is also developing to enhance the user experience under the environment of ICT.

Teleconference will be more realistic such as by identifying their expressions, line of sight

and others.

stored data

Upload home power

usage data

A service that measures, collects, and visually presents data on power usage in the

home, thereby helping with power saving, is provided


Period

July to September of 2012 (3 months)

Area

About 300 households mainly in Kansai area

c) Trial for Power Peak Cut

Overall configuration Dedicated Web site

Checking of energy saving result at each home

Saving of energy based on request for energy saving

Report on questionnaire (about energy saving

implementation, etc.), etc.

Request for energy saving by e-mail ,etc.

Concurrent control of home electrical

appliances (air conditioner, TV, etc.) with

a remote controller

Trial of concurrent control of home electrical appliances using a remote controller.

Compare to the self power saving by using the cloud service,

this trial is more active that power usage is controlled from cloud side.


Cloud services for Town

Smart Hikari Town

Kumamoto Project

With Kumamoto City, Kumamoto Pref., we have conducted trials using ICT to meet regional

challenges, revitalize local communities, and improve services for citizen on FTTH.

d) Trial for “Smart Town”

Government

Welfare centers, Schools

Tourist spots

Farm stand

Michi-no-Eki (roadside rest area)

d-1) Trial services for seniors

Health care & promotion services, seeing and supporting services for seniors

Trial in FTTH service areas in Kumamoto Pref.

(Feb. 25 – Mar. 15 2013)

TV switch on/off monitoring

Support for local event application Information Sharing on TV

Exercise course based on

the health data stored in

cloud

Head mount camera

Health care &

promotion services

Services

community center

“Visual” is easier way to communicate for not only seniors but also operators.


d-2) Transportation information

Provide current tram and bus location

information in real time.

Information can be seen by a smartphone

http://www.smart-hikari.jp/transit/mobil.html

or Digital signage terminal at major stations.

Visualizing bus locations on map is good for

tourists or visitor to understand where and

how far the bus is now.

Summary

Introduced activities for Green & Smart life on FTTH • ICT services (Video conferencing, HEMS, etc.) drive down

energy consumption

• Smart Town on FTTH is under trial in Kumamoto, Japan.

NTT group will contribute to realizing Green ICT

・ NTT is tackling Green ICT in many fields, not only FTTH.

FTTH has become basic service in Japan.


Thank you very much.
