Yet some observers suggest TD-SCDMA's slow progress could be fatally undermining official backing for the standard.

China Mobile is the country's dominant wireless operator and the one now widely seen as most likely to be issued a TD-SCDMA licence.

Unlike the two rival foreign standards, TD-SCDMA has yet to be commercially deployed.

"China Mobile has done a pretty good job with TD-SCDMA in such a short period, " Mr Wang says.

Through the move Nokia will gain access to TD-SCDMA technology developed by Putian while contributing its expertise in WCDMA.

"I think there was a gap some years ago of two to three years (between TD-SCDMA and the other 3G standards), " he says.

This paper introduces the smart antenna technology and its application in TD-SCDMA system.

TD-SCDMA combines both wireless and core network technology advantages, have become the mainstream of the best 3G.

"Our supply chain is complete, but weak, " explains Wang Jing, secretary-general of the TD-SCDMA alliance.

A method of measuring TD-SCDMA signal frequency error based on virtual instrument is proposed. Then the system design is presented.

With the arrival of the domestic 3G commercialization, market examination on TD-SCDMA industrial chain just begins.

Unfortunately, after three days of intensive use, our FT colleagues' verdicts on the TD-SCDMA service were damning.

The Dynamic Channel Allocation (DCA) technology enables flexible resource allocation and efficent frequency usage in TD-SCDMA system.

Without subsidies, TD-SCDMA handsets are unlikely to become a mass market phenomenon.

Mr Wang denied criticisms that technical problems with the network were hampering growth.

But Duncan Clark of consultancy BDA says official support for TD-SCDMA may be weakening.

In Beijing in TD-SCDMA engineering investigation and engineering design work, and independent design CAD drawing.

Secondly it takes focus on the advantage, realization project and the new problems about the Smart antenna applying in TD-SCDMA system.

TD-SCDMA, by contrast, already risks being labelled as an also-ran.

After company reorganization, China Mobile is responsible for the promotion of national 3G brand TD-SCDMA.

But the plan to establish TD-SCDMA as a global 3G standard and sell gear to other countries now seems doomed to fail.

Based on CDMA technology, SCDMA technology was developed independently by Beijing Xinwei Telecom Technology Company.

At last, summary is made as well as the scope for the evolvements and challenges of TD-SCDMA terminal test set.

and solving the difficulties in web-coordination of TD-SCDMA base station by brainstorm.

But even observers who think Mobile will persevere with TD-SCDMA say it will be a challenge.

This also makes exhibit dispatch to will buy supplier of TD-SCDMA RF chip before the hearsay collapse of itself of vessel core.

To determining the victory of 3G, China Mobile Communication Corp is actively preparing the TD-SCDMA network creation.

Not everybody agrees that TD-SCDMA is in serious trouble.

China Mobile currently sells a range of 40 TD-SCDMA handsets but Mr Wang said "several hundred" mobiles were required.

"If my cellphone model is TD-SCDMA, then could I use [other networks] when I go abroad? " one Weibo user wrote.

TD-SCDMA will provide subscribers more assured quality of service.

With the development of TD-SCDMA mobile telecommunication technology, radio network optimization is becoming increasingly important.

Yet our FT testers make clear that much remains to be done to improve the TD-SCDMA service.

Ningde began construction of TD-SCDMA from 2009, mainly covering the important areas of urban areas of Ningde.

Frequency planning has become an essential step in the introduction of N frequency points in TD_SCDMA.

The carrier earlier in February issued the first TD-SCDMA licenses to ZTE, Hisense, LG, Samsung, Lenovo and New Postcom.

A dynamic channel allocation strategy is proposed for TD-SCDMA.

Since there is a lack of the researches on performance in SCDMA wireless access network, so the study of the paper is very necessary.

But because Apple's device doesn't support China Mobile's home-grown TD-SCDMA standard, those customers aren't getting 3G speeds.

China Mobile's 3G network used a homegrown Chinese standard called TD-SCDMA, and China Telecom uses CDMA-2000 technology.

TD-SCDMA in China has grown rapidly, and it is now the only large-scale deployment of 3G networks in China.

The plan involved the development and promotion of a Chinese 3G technology called TD-SCDMA, or TD-S.

Mobile TV is a key service in TD-SCDMA system, and the multimedia broadcast multicast service (MBMS) is introduced to 3GPP R6.

TD-SCDMA lags far behind the more established international 3G standards, WCDMA and CDMA2000.

China Mobile is using a largely unproven 3G technology called TD-SCDMA.

The government tried to promote a home-grown 3G technology, TD-SCDMA, or TD-S, against foreign standards.

Just remains to mature because of TD-SCDMA, be sure to bring unprecedented development opportunity to test instrument appearance market.

There are still far fewer handsets available for TD-SCDMA than for the more established 3G standards, and they cost more per unit.

China Mobile was forced by the government to roll out 3G services using the less stable TD-SCDMA standard.
