China Unicom, the country's only mobile-phone operator using the CDMA standard, aims to boost revenue from mobile data to more than 20 per cent of total CDMA sales as an increase in handset choice improves demand for new services, a company official said. The company would boost use of CDMA mobile data services by offering more industry and business applications, such as location-based positioning for the fishery and police sectors, said James Shen, general manager of Unibrew, a joint venture between Unicom and Qualcomm on CDMA's mobile data service. The mainland's smaller mobile operator is also pushing real-time mobile stock trading on its CDMA service as it seeks to benefit from increasing public interest in the mainland stock market. Unicom is seeking to attract more users to its CDMA 1X network. Withdownloading speed of more than 100 kilobits per second, it is comparable with the speed of some third-generation networks and faster than China Mobile's GPRS mobile data service. Unicom's Brew service, launched four years ago, has about five million users out of the company's more than 40 million CDMA subscribers. It aims to attract more users as the country's economic boom increases the number of subscribers willing to pay for non-voice services. 'As we have over 10 million Brew-compatible handsets in the market, there is still room to increase the penetration of the service,' Mr Shen said. Unibrew has more than 300 service providers and has been developing more than 10,000 mobile applications for the Brew platform. These applications, including music downloads, Java games and mobile video, contributed 19 per cent of CDMA service revenue last year. 'We believe that data service revenue will account for more than 20 per cent of CDMA service revenue by the end of this year,' Mr Shen said. Unicom claims the Brew mobile data platform is more secure in sending sensitive data than other mobile technology. Unicom's CDMA users, who already have a securities trading account with a brokerage, need to pay only an addition 20 yuan to 30 yuan per month for the real-time stock data and stock trading service. 'By leveraging on Qualcomm's Brew mobile data platform, we can offer an end-to-end security protection to users,' said Mr Shen.
