ObjectivesTo develop mobile communication systems capable of transmitting data 100 times faster than current technology by FY2010

PoliciesIn order to develop systems capable of data transmission at 100 times current speeds, Japan must utilize its strengths in mobilecommunications technology and markets and pursue research and development into world-leading technology and applications through joint initiatives involving the public, private and academic sectors, while at the same time pursuing validation testing and standardization in the international arena with a view to developing practical systems harmonized with international trends.

Development of 4G mobile communications systemsJapan will actively contribute to the work of the ITU in developing international standards, particularly in the area of R&D and validation testing of 4G mobile communications systems capable of data transmission at 100 times current speeds geared towards developing systems to market by FY2010, through initiatives such as technology trials for bandwidth sharing with other radio systems, allocation of frequency bands and selection of radio communication formats

R&D into 4G mobile communications technology• Using 4G mobile communications technology to create the world’s most advanced mobile IT environment• Promoting world-leading R&D, making an active contribution to international standardization processes, developing base technology by 2005 for market implementation by 2010.
