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.

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.

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
Seeing and supporting
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.
