DoCoMo Announces New 3G Platform JV

NTT DoCoMo, Renesas, Fujitsu, Mitsubishi, Sharp and Sony Ericsson have announced that they plan to jointly develop a next-generation mobile phone platform with completion targeted for mid-2008. Renesas plans to provide the platform to the global W-CDMA market, in addition to customers in Japan, aiming to further reduce costs. The six companies have agreed to the joint development project in an effort to provide advanced functionality – with a common base – for 3G handsets worldwide.

Radio Waves Declared Safe

Japan’s mobile phone operators, NTT DoCoMo, Inc., KDDI Corporation and SoftBank Mobile Corporation have confirmed that radio frequency energy from mobile phone base stations does not cause damage to human cells in vitro studies. Since November 2002, the companies have been collaborating to examine the effects of radio waves. As part of the collaboration, large-scale experiments have been conducted on the cellular and genetic level using radio waves up to 10 times stronger than the limit set forth in radio frequency radiation protection guidelines for base stations. In an interim report on April 26, 2005, the companies announced they had found no effects on cell proliferation, gene expression profile, or DNA single-strand breaks. Now they have found there are no genetic alterations or protein functions that could be associated with cell transformation or programmed cell death (apoptosis).

DoCoMo Announces i-mode for India

NTT DoCoMo and Hutchison Essar announced today an agreement under which Hutch will launch the i-mode mobile service in India within 2007. DoCoMo will license the patented technologies and know-how needed for Hutch to offer i-mode on GSM, GPRS and W-CDMA networks. Preparations are also underway to launch i-mode in Hong Kong, Macao and the Philippines. DoCoMo plans to expand the service to a total of 26 countries/regions in the future.

Fujitsu to Develop Super 3G Base Stations

Fujitsu Limited today announced that it has been selected in NTT DoCoMo’s procurement process to develop and manufacture prototypes and commercial equipment for DoCoMo’s super 3G wireless base stations. Fujitsu has been actively involved in the 3GPP’s standardization initiatives from the outset, and has been developing the fundamental technologies required to improve spectrum efficiency for the Super 3G standard, such as multi-antenna system and OFDM technologies.
