The adage that Hong Kong is the shop window of the world holds true even for purveyors of hi-tech, none more so than Qualcomm, the United States-based supplier of digital wireless communications products and services. The company is sponsoring and participating in the Expo Comm Wireless Hong Kong '97 and displaying a number of its top-of-the-range applications. The company develops, manufactures and markets many ground-breaking products using Code Division Multiple Access (CDMA) technology. CDMA serves as a base for a new generation of digital wireless products. These include infrastructure equipment and subscriber products for cellular systems, personal communications services (PCS) and wireless local loop systems. The discipline also allows a large number of users to share the same radio frequency, significantly improves voice quality and increases capacity by 10 to 20 per cent over analog cellular systems. Last year, Qualcomm Personal Electronics, a joint venture of Qualcomm and Sony electronics, received two CDMA phone orders valued at US$850 million from Sprint Spectrum and Primeco Personal Communications, two of the leading PCS licence holders in the US. 'This is an enormous vote of confidence in our capabilities,' Irwin Jacobs, chairman and chief executive officer of Qualcomm, said. In addition to its CDMA range, Qualcomm will be displaying Omnitracs two-way mobile satellite communications and tracking systems, which are used primarily by trucking and taxi fleets. Qualcomm is also a founding member of Globalstar, L. P. The Globalstar system is a low-orbiting satellite-based digital communications system that will begin providing mobile and fixed services next year. Qualcomm has been awarded contracts to develop and manufacture ground operations control centres, gateways and subscriber terminals for this grand-scale system using CDMA digital wireless technology. Qualcomm's award-winning Eudoral Light and Eudora Pro software is now the world's leading Internet e-mail package, used by more than 10 million subscribers. Also, a number of industrial and consumer wireless communications products made by Qualcomm will be on display. Qualcomm was founded in San Diego, California. The company employs more than 6,000 people in its various international offices.
