Hitachi, Ltd.(TSE:6501)  today announced that it has signed a letter of intent with QUALCOMM 
(Nasdaq: QCOM), to jointly develop equipment and support a field trial of QUALCOMM's 
High Data Rate (HDR) technology beginning in mid 2000.  Following a successful trial, Hitachi 
intends to develop and manufacture HDR infrastructure equipment for commercial use.

"The demand for wireless data services is growing around the world," said Yasuo Katou, 
General Manager of CDMA System Business Operation, Telecommunication Systems Divison 
of Hitachi, Ltd.  "We believe we can help carriers meet this growing demand by offering 
equipment that provides high-performance, cost-effective wireless data services through HDR."
"Optimized for packet data, HDR enables high-speed, always-on wireless Internet access using 
standard Internet Protocols," said Irwin M. Jacobs, chairman and CEO, QUALCOMM.  "We are 
pleased that Hitachi has recognized the merits of HDR and plans to manufacture infrastructure 
equipment to support the deployment of HDR.  We look forward to working with Hitachi to 
make the HDR a success." 

Technical trials of HDR are expected to begin in the middle of 2000, and the marketing trials and 
commercial rollout are expected to occur during 2001.  Initial HDR network trials will 
incorporate evaluations of HDR's air-link performance, advanced feature sets, decentralized 
Internet Protocol (IP)-based architecture and highly integrated access points.  HDR supports e-
mail, web browsing, e-commerce, telematics and many other applications while offering end-
users continuous, untethered access to the Internet and next generation data services.  HDR's 
versatility allows the technology to be embedded in handsets, laptops and handheld computers, 
and other fixed, portable and mobile devices.  

HDR provides a spectrally efficient 2.4 Mbps peak rate in a standard 1.25 MHz channel 
bandwidth.  Optimized for packet data services, HDR incorporates a flexible architecture based 
on standard Internet Protocols (IP).  HDR's IP-based architecture allows flexible implementation 
of this wireless system in high-performance and cost-effective ways.  As a complementary 
solution to voice networks utilizing operator's existing cell sites, towers, antennas and network 
equipment, HDR technology allows operators to leverage their current infrastructure investment 
and cellular/Personal Communication Services (PCS) networks.  HDR can also be implemented 
as a stand-alone system using off-the-shelf IP backbone equipment.  HDR is compatible with IS-
95A, IS-95B and future cdma2000(TM) networks, enabling existing cdmaOne(TM) and cdma2000 
service providers to obtain higher capacities and superior performance by optimizing voice and 
data spectrum separately, serving both applications from the same network.
