>>Siemens AG's China unit will test its time-division synchronous code-division multiple-access, or TD-SCDMA, standard, which it is developing jointly with state-run operators especially for the China market. Its standard will be challenged by wideband- CDMA, and U.S.-based Qualcomm Inc's CDMA2000. The ministry will ``make the official decision depending on the results of the first trial runs in the first quarter of next year,'' said Juergen Lagleder, Siemen's senior vice president. << Is TD-SCDMA that far along that it can run trials in first quarter 2001?

TD-SCDMA claims: 1. >>TD-SCDMA simultaneously sends and receives cellular phone signals, called time division duplexing, or TDD. That means it can squeeze about three times more voice and data signals into airwaves than other standards, Siemens officials said. 2. >>TD-SCDMA is the ideal technology for migrating GSM cellular phones to third generation standards, especially for network operators who want to offer Internet and data services on a limited radio spectrum,'' said Yu Xiangguo, Siemens' 3G Network general manager in Beijing. 3. >>TD-SCDMA will also allow operators such as China Mobile Ltd. and China Unicom Ltd., the nation's No. 1 and No.2 phone companies, to offer Internet connections through their cellular phone systems, without having to make major changes to their equipment. 4. >>``The migration from GSM to TD-SCDMA is smooth, so the operators don't have to strip the entire network or install new base stations,'' Lagleder said.<< Wow -- TD-SCDMA ! Anyone technology gurus on this board who can comment on the claims of TD-SCDMA?

3G mobile trial due in Beijing Dec 5 2000 3:49PM Homeway China is expected to launch a trial for the third-generation (3G) mobile phone network in the first half of next year and commercial 3G operation in 2002, the China Daily reports. Cao Shumin, chairman of the China Wireless Telecommunications Standard of the Ministry of Information Industry, disclosed this Monday. The trial will be carried out in Beijing, but the network operator has not been determined, she said. All telecom carriers have indicated their interest in the trial and it is possible that several of them would hold the technical experiment in different places. Cao said the government is working on 3G commercial standards of all TD-SCDMA, WCDMA and CDMA2000, which should be completed next year. A forum to promote TD-SCDMA standard, which has become an ITU-recognized standard as proposed by the relevant government department, would be launched on December 12 in Beijing. The forum will have about 150 members, most of whom are domestic manufacturers, Cao said. China and 3G have been the most frequently discussed topics at the ongoing International Telecommunication Union Telecom Asia 2000, being a combination of a huge market and the future of telecom and Internet. Wu Jichuan, minister of information industry, said the mainland's telecom market is expected to double in the coming five years, at a growth rate which is 20% higher than the overall economy. Wu said fixed-line and mobile phone subscribers grew to 200 million this year, doubling since 1998. It took 13 years for China's fixed-line and mobile phone users to grow from 2.03 million in 1979 to 10 million in 1992, Wu said. Internet users reached 20 million in September, he said. The immense market potential has lured all major equipment providers. Qualcomm chief Irwin Jacobs said China Unicom, one of the mainland's two mobile operators, could begin deploying a 10 million-subscriber network based on Qualcomm's proprietary CDMA technology in early 2001. Qualcomm has signed a Memorandum of Understanding with MII confirming a Framework Agreement with China Unicom to use Qualcomm's 2G CDMA technology, which was signed in January. Despite market skepticism in the past few months about the high cost and revenue outlook of the 3G networks, Yoshio Utsumi, ITU secretary-general, remains positive about the future application of the technology. ITU has worked to set up a standard, coordinated in allocation of frequencies. ITU is promoting details of standardization of the technology, Utsumi said.
