SAN DIEGO -- May 24, 2000 -- Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, in cooperation with Nippon Idou Tsushin Corp. (IDO) and Hitachi, Ltd., today announced that a High Data Rate (HDR) technology field trial will begin this year in Japan. Following a successful trial, Hitachi intends to develop and manufacture HDR infrastructure equipment for commercial use worldwide.

"We look forward to evaluating the performance of HDR in Japan. The successful completion of this trial will mark an important step in our effort to expand our service offering through new Internet-related applications, including multimedia and electronic commerce," said Akira Nishiumi, director and general manager, engineering department, IDO.

"With a more efficient use of spectrum, HDR will ensure IDO continues to broaden its customer base."

"With strong support from Qualcomm, we anticipate a successful trial and look forward to the commercial deployment of HDR in Japan," said Yasuo Katou, general manager of CDMA Systems Business Operation, Telecommunications Systems Division of Hitachi. "The superior performance of HDR will help meet the growing global demand for wireless data services and confirm Hitachi's position as a leading provider of HDR infrastructure."

"HDR's proven capabilities as a leading wireless Internet access technology continue to attract significant interest from operators and manufacturers," said Jeff Jacobs, senior vice president of business development, Qualcomm. "We look forward to meeting the increasing demand for bandwidth with the commercial deployment of HDR."

HDR provides a spectrally efficient 2.4 Mbps peak rate in a standard 1.25 MHz channel bandwidth for fixed, portable and mobile applications. Optimized for packet data services, HDR incorporates a flexible architecture based on standard Internet Protocol (IP). HDR is an evolution of CDMA technology with identical radio frequency characteristics as cdmaOne™ and 1x Multi-Carrier. HDR supports e-mail, web browsing, mobile e-commerce, telematics and many other applications while offering end users continuous, untethered, always-on access to the Internet and next-generation data services.
