TOKYO--(BUSINESS WIRE)--Aug. 8, 2002

Hitachi, Ltd. (NYSE:HIT/TSE:6501) today announced it has received an order for CDMA2000 1xEV-DO radio access network systems for both 2GHz band and 800MHz band. KDDI will launch test service in April 2003 for 2GHz band systems and commercial service in autumn 2003 for 800MHz band systems. CDMA2000 1xEV-DO systems provided by KDDI consist of IP network, multi-vender radio access networks, and mobile terminals. Among these, Hitachi is responsible for radio access network.

CDMA2000 1xEV-DO, one of 3G mobile communications systems using CDMA technology, was originally developed by Qualcomm, Inc. (U.S.A.) and optimized for mobile high-speed data services. The system adopts IP based network architecture and provides a peak data rate of 2.4 Mbps within one 1.25MHz CDMA carrier. Due to high compatibility, CDMA2000 1xEV-DO can utilize existing CDMA2000 1x/cdmaOne cell sites, towers, and antennas. Furthermore, CDMA2000 1xEV-DO has been registered to ITU as one of third-generation Mobile Communication Systems (IMT-2000) after completing its specification in 3GPP2.

Hitachi has been cooperating with KDDI to evaluate the performance and service of CDMA200 1xEV-DO by providing systems for field tests conducted by KDDI in Tokyo since 2000. Hitachi believes the factors for this vender selection were Hitachi's technical experiences gained from these field tests and superiority of equipments.

Hitachi will seek to expand the sales of next generation telecommunication systems by leveraging these experiences and its technical know-how.
