Laptop, PDA etc.
Mobile usageNationwide deployment by telecoms with a focus on urban areas. Services that support medium-speed movement are also provided.
Stationary usageIn areas with poor reception, relatively long-range relay links and subscriber lines are provided, which make use of high-gain antennas.

• Video-compatibinterfaces, etc.
• Emphasis on quality of voice communications
• Limited by type of data communications device and charge rates
• Vertical integration business model
Features of the XGP*(eXtended Global Platform)
・Devices based on OFDMA technology that were introduced in WiMAX and LTE can be used for XGP system with only minor design or software changes.
・The size of a microcell in rural areas can be as large (several km of radius) as other OFDMA systems.
・In urban areas, it is possible to reduce cell size, which results in greater capacity.
・With the adoption of autonomous control, it is easy to build a wireless network both in rural and urban areas.
・The convenience of autonomous control will be exploited in network maintenance and cell design phase.
・It is possible to construct and operate a wireless network without requiring in-depth knowledge of frequency operations (Optimum frequencies are automatically selected).

Outline of Research Seminar on ICT Policy for Combating Global Warming
Helping to combat global warming by promoting more widespread use of ICT
Improved efficiency in energy usage Reductions and efficiency in manufacturing and consumption
Reduced movement of goods and people Environmental measurement and forecasting
・ ITS (ETC, VICS, central control of traffic signals)・ BEMS (Business Energy Management Systems)・ HEMS (Home Energy Management Systems)
・ Supply chain management・ Electronic publishing and delivery・ Paperless offices
・ LIDAR for measuring CO2 levels・ Sensor networks・ Global simulators
・ Online shopping, on-line transactions・ Telecommuting, teleconferencing・ Distribution of music, movies, and software・ Online application procedures (Online tax
filing, Online prescriptions)
○ In order to reduce CO2 emissions, it will be necessary to reduce the production of CO2 in the ICT industry itself.
○ With widespread use of ICT it will be possible to help to reduce CO2 emissions, by drastically improving efficiency in manufacturing, consumption, and business, by substituting transportation needs and by alleviating traffic congestion.
○ It is possible to conduct environmental measurement and forecasting using ICT.
Widespread use of ICT

ITU Symposia on ICTs and Climate Change1 Objective
To raise awareness regarding the importance of using ICT to respond to and to reduce the effects of climate change, and to discuss future standardization activities at ITU.
2 Kyoto SymposiumDate: April 15 and 16, 2008Location: Kyoto International Conference CenterSponsor: Ministry of Internal Affairs and Communications, International Telecommunications Union (ITU)Chairman: Takashi Hanazawa, Director of Research and
Development Planning Department, NTTChairman’s report・Making devices energy-efficient and use of ICTs in responding to climate change・To this end, establishing international standards for evaluating the amount of CO2 emissions reductions using ICT
3 London SymposiumDate: June 17 and 18, 2008Location: British Telecom Headquarters (London, England)Sponsor: ITU and BTChairman: Mr. Walker, British Department of Business, Enterprise and Regulatory ReformChairman’s report・ Direction of activities: Energy efficiency of ICT and use of ICT to improve efficiency in other sectors, changing business/consumer behavior・ Early implementation of international standards concerning ICT and climate change
・Established a Focus Group in the Telecommunication Standardization Advisory Group (TSAG) (July 2008) and began the study.
・The Focus Group will study reduction of CO2 emissions by ICT.
