TOKYO, JAPAN, July 12, 2004 ---NTT DoCoMo, Inc. announced today that the company will invest in Renesas Technology Corp. to jointly develop a single-chip LSI making FOMA® 3G handsets compatible with both W-CDMA and GSM/GPRS networks.
Currently, it is necessary to embed two chips in order to produce a W-CDMA and GSM/GPRS dual mode handset. However, by combining DoCoMo's W-CDMA technology with Renesas Technology's LSI fabrication, multimedia application processor and GSM/GPRS technologies, a single-chip will be developed that enables a lower cost 3G handset to run on both networks.
DoCoMo's investment is a step toward bringing about the widespread global use of 3G FOMA compatible handsets incorporating low-cost chipsets, and which feature an array of power-efficient advanced functions. Enhanced chipsets will also enable the upgrading of basic FOMA handset functions, such as longer standby-time.
DoCoMo will provide a total of about 7 billion yen over three years (fiscal 2004 to 2006) to Renesas Technology.
Following up on this investment, DoCoMo plans to continue actively promoting research and development of 3G and mobile multimedia services in order to further enhance the value of these services to the user.
