idler,
Please read the bold print of the following article. No one knows how good their CDMA systems are? Datang has also developed SCDMA system for a while. IDC's similarity just comes to mind.
CDMA Technology Forges Ahead In China
(2/24/2000) The February 17 Renmin Youdian (People's Post & Telecommunications) presented an overview of Code Division Multiple Access (CDMA) technology and its application in China.
China?s mobile communications sector has developed rapidly in recent years. With over 43 million users, China now ranks third in the world regarding the scale of mobile communications networks. After a decade of development, China has the world's largest GSM network and plays a decisive role in the world's communications market, said the newspaper.
To tap the great potential of mobile communications, China has also prioritized the development of CDMA networks. In the mid-1990s, China constructed experimental CDMA networks in Beijing, Shanghai, Guangzhou and Xi'an and put them into operation.
Authorized by the Ministry of Information Industry, China Unicom has devised a grand plan for the building of CDMA networks. Unicom says that it will provide a quality network as well as more options in mobile communications to its users through advanced CDMA technology, said the newspaper.
Last June, Unicom joined the CDMA Development Group (CDG), a global organization consisting of over 100 telecom manufacturers and operators. At the Fourth CDMA Annual Symposium last year, Executive Deputy General Manager Wang Jianzhou announced Unicom's CDMA development plan.
At this symposium, Unicom also proposed that the CDG should implement the plan to separate CDMA cellular phones and user id cards ahead of the original completion date of 2003. Unicom argued that the lack of separation in the present CDMA system made it inconvenient for users to change cellular phones. This problem also retarded the development of advanced card service.
The CDG quickly responded by holding an emergency teleconference among world famous CDMA operators, which passed Unicom?s proposal and agreed to implement the separation plan at the end of 1999.
China's telecom industry has long been interested in CDMA technology. Chinese telecom manufacturers have devoted considerable human resources and materials to the R&D of CDMA technology. The government has also allocated funds for such research and a number of important breakthroughs have been made, the paper reported.
The CDMA mobile exchange system developed by Datang Telecom obtained a network access certificate from the Ministry of Information in 1999. The CDMA base station developed by Putian has also made significant breakthroughs recently and begun preparations for industrialization. Other enterprises like Zhongxing have also made progress in CDMA R&D. Thus, said the paper, China has laid a solid foundation for CDMA development.
According to the newspaper, throughout all this, China has protected intellectual property rights in CDMA development. Therefore, the paper said, Chinese manufacturers of communications equipment welcome the CDMA Intellectual Property Rights Accord reached between Unicom and Qualcomm, deeming that it will benefit CDMA development in China.
President Xiong Bingqun of the Datang Telecom Science and Technology Co., Ltd. said that the signing of the agreement will promote the development of China's CDMA industry. Meanwhile, because the agreement embraces the wireless communications equipment of CDMAOne based on the IS-95 standard and the third generation CDMA2000 (including 1X and 3X), it will benefit China's development of the third-generation mobile communications system.
