Quick question. Trying to get at the gist of this release. Can HDR be overlayed/added on top of any system, GSM for example? Thanks!Hitachi, Qualcomm Tie Up On Data-Only Mobile Telecom System Tuesday, January 11, 2000 TOKYO (Nikkei)--Hitachi Ltd. (6501) has tied up with Qualcomm Inc. to commercialize a system to send non-voice data to and from mobile terminals, The Nihon Keizai Shimbun has learned. The system was developed by the large California telecom equipment manufacturer. The pair will conduct joint feasibility tests of a High Data Rate (HDR) system this summer, and Hitachi will invest some 10 billion yen on building a domestic production line by year-end. Sophisticated cell phones, which use international standards to enable rapid transmission worldwide of voice and visual data, are seen to have the strongest growth potential in the area of high-speed mobile communications. Such high-speed transmission is needed for cell phone-Net hookups.Hitachi and Qualcomm believe, however, that separating the visual and text data transmission system from the voice data allows major global telecom firms -- to whom the data-only system will be sold -- to cut capital spending costs. The system that Hitachi and Qualcomm will try to commercialize has a maximum throughput of 2.4 megabits per second, or about the same as sophisticated cell phones. Such cell phones handle both sound and data transmission and require capital spending by companies on facilities of some 1 trillion yen per network. A network built with HDR focuses exclusively on communications efficiency and enables the same frequency band to cover three times the number of users. Also, capital spending costs for telecom firms are relatively low, at approximately 200 billion yen per new network. Qualcomm had more than 35 million subscribers to its voice cell phone service as of June 30. (The Nihon Keizai Shimbun Tuesday morning edition)
