Hitachi Awarded Order for Its Access Service Network Gateway for
Mobile WiMAX and Integrated Operation Maintenance System from
UQ Communications Inc.

Hitachi to Provide Nation's First Commercial System

Tokyo, March 3, 2008 ? Hitachi, Ltd. (TSE: 6501 / NYSE: HIT) has received an order for its Access Service Network Gateway*1 for Mobile WiMAX*2 and Integrated Operation Maintenance System*3 from UQ Communications Inc., which will introduce commercial services in fiscal 2009.

Mobile WiMAX is one of the core technologies for the next generation of high-speed wireless communication service, and will permit the Internet to be accessed from a PC or other communication terminal even while one is traveling. Authorized in December 2007 to plan and set up 2.5GHz specific base stations, UQ Communications is planning the deployment of a wireless broadband network incorporating mobile WiMAX technology for rollout of the Japan's first commercial services in fiscal 2009.

Development of the Access Service Network Gateway for Mobile WiMAX and the Integrated Operation Maintenance System is based on a 3G mobile high-speed data communication system utilizing the CDMA2000 1xEV-DO*4 system Hitachi made a practical option in 2003. Specifically, for the first time in Japan, the gateway will be made commercially available for Mobile WiMAX as a carrier grade reliability system and for faster data communication. All of these products are being developed and manufactured by Hitachi Communication Technologies, Ltd., a wholly owned subsidiary of Hitachi that specializes in the development, production and servicing of network equipment.

Product Features

1. Access Service Network Gateway

(1) Scalability to meet all traffic needs

A single concept governs all systems, no matter how small or how large. The architecture, which separates the protocol processor from the traffic processor, dramatically increases the flexibility necessary for handling future traffic needs.

(2) Carrier grade redundancy switchover function

The gateway is equipped with a non-stop configuration that attains carrier-grade quality. With the mirroring of operating information and an instantaneous change of IP address, switchover to the redundant system occurs without affecting base stations and other connected terminals.

(3) Throughput at ultrahigh speeds

The advanced packet engine achieves ultrahigh-speed throughput performance.

2. Integrated Operation Maintenance System

(1) Sophisticated monitoring and control functions based on proven operation

To improve operational performance, this system has been designed based on the proven interoperability of a variety of communication devices, including the Hitachi CDMA2000 1xEV-DO System

(2) Monitoring terminal employing web browser functionality

The monitoring terminal is equipped with web browser functionality that does not require any terminal monitoring software. Not only is the monitoring terminal able to concurrently maintain the gateway for Mobile WiMAX and base stations, but the use of a common interface also enables the integrated operation of several types of base station.
