TD terminal business-related sources, is currently involved in testing a TD terminal can not support the HSDPA function, the chip is limited by the maturity of the issue, in accordance with the progress of TD terminals to support HSDPA functionality will be available first quarter of 2008.
Recently, Citigroup announced the report pointed out that lack of preparation of mobile phones is expected that China Mobile's TD-SCDMA network commercial time may be delayed.
Report is based on this conclusion, China Mobile phone can be compatible with requirements of TD and GSM network roaming, HSDPA, EDGE dual-mode and low power consumption, Citigroup is expected to reach the fastest growing mobile phone required to be available in early 2008.China Mobile has 8 major cities in the Mainland and the construction of 10,000 TD base stations in some cities has reached 85% of the network infrastructure.
However, TD terminal companies denied the claims, a major domestic terminal manufacturers, has not yet received a bid of China Mobile's TD timetable, but all tests were carried out according to plan, networks and commercial time will not complete the change.
Terminal network by the end of September again
"Test, test, or tests, progress is currently the largest test." When the "First Financial Daily" to try to understand the recent progress made TD, a TD Union Terminal responsible persons described as such.
According to the source, after the end of the TD equipment bidding, equipment manufacturers primarily engaged in supply according to the agreement, China Mobile has not given the tender notice issued by the terminal operators, so the test to become a major task.
This reporter has learned, from the end of June to July, China Mobile has completed the first round of diagnostic tests, involving manufacturers, including Inventec, Hisense, Holley, ZTE, Panda, Amoi, Samsung, Huawei, Motorola, UT StarKang, dragon flag, LG, Haier, Lenovo, New Postcom, Datang Telecom, Simcom, Bird and other 18 enterprises.
Tests include: machine card compatibility testing, basic services, supplementary services, EHPLMN, video phone, WAP, Java, MMS, Push, and more.
According to reports, the terminal take the test in October 2007 as demand for the target design and development of new terminals, all of which can achieve TD / GSM Automatic switching products, the original model of the old terminal will not continue if the listing does notcontinue to take the test, the test up to 10 months to complete.
In addition, in late August, China Netcom will organize 80 TD-SCDMA mobile phone models tested in Qingdao, China Netcom, this is the first round of TD-SCDMA terminal tests, the test results will directly affect the subsequent terminal procurement.
The person said that the operator completed the test, the Ministry of Information Industry CTA test (ie network testing) is expected to start at the end of September, and only passed the test in order to obtain the terminal network card issued by the Ministry of Information Industry.
In fact, the TD test in three cities involved in the terminal manufacturers have received a Ministry of Information Industry of the test network network cards, but the sale also need to formally network cards, then just look at whether the issue is to test the network vendor network cardor an ordinary network card to the network can determine the commercial TD concrete progress, informed sources.
According to initial plans of China Mobile, TD trial network will be October 31, 2007 formally completed, after which the public will be 放号 TD, TD manufacturers believe that, regardless of supplier progress in TD rumors some time ago or now spreadTD terminal equipment is not lack of test problems, after all, for equipment and terminals can not be completed immediately, but according to progress in a gradual manner.
The Ministry of Information Industry and China Mobile has not announced when the official commercial TD network schedule, nor to the diagnostic equipment manufacturers issue a tender notice, called a say on the delay to go too.
The reporters also learned that the end of the testing, and Telephone Number of TD commercial trial network a major impact on the formal, so China Mobile has strictly prohibited any release of foreign manufacturers of the progress of TD terminals, and to promote actively the manufacturers issued a warning notice.
The first terminal does not support HSDPA Telephone Number
Although China Mobile has HSDPA (3G enhanced technology) function given high priority, but the current progress in perspective, the first Telephone Number of TD terminals will not support HSDPA feature.
It is understood that early stage in the communication before the test, China Mobile will give forth requirements for the terminal manufacturers: "the full support of the system unit case of HSDPA, HSDPA terminals have a large number of launch."
Union and Telecommunications Research Institute for the TD to do the planning for the long and active research.TD terminal to achieve the smooth switching between the TD and the case of GSM, support HSDPA feature that allows data transfer rates of TD from the current 384K raised to 2.8Mbps, on this basis, the further evolution of a higher rate of HSDPA.
TD terminal business-related sources, is currently involved in testing a TD terminal can not support the HSDPA function, the chip is limited by the maturity of the issue, in accordance with the progress of TD terminals to support HSDPA functionality will be available first quarter of 2008, alsoThat October, after the first 放号 TD terminals will not support HSDPA feature.
In fact, the COMMIT Information Technology Co., Ltd. (COMMIT) in April this year, has officially launched its support function of the TD-HSDPA HSDPA chipset solution; Not long ago, RDA also announced the launch of the world's first to support HSDPA TD / GSMdual-mode RF chip.But the terminal company told reporters that the maturity of a large-scale dual-mode HSDPA chip still needs time, so the current test TD / GSM dual-mode terminals to support HSDPA, only prototypes, but not test machine.
The ability to support the HSDPA function, a direct impact on mobile TV network in the progress of TD.Business people involved in the testing of the terminal, said terminal on the TD in the current mobile TV functions can be achieved already, but the picture quality and speed of data transmission can not be very satisfactory, at least not fully reflect the advantages of 3G.
According to China Mobile's plan, the 2008 Beijing Olympic Games, will use the TD-SCDMA networks and terminals to provide mobile phone service to see the Olympic Games, China Mobile, which is to create "mobile phone Olympics" important important deployment, is a way of broadcasting the Olympics over the years a great innovation.
Another view is that the public face of the first TD Fang Hao, the most important is stability, by gradually testing the market for TD 放号 response to the demand for mobile TV is not very strong first quarter of 2008HSDPA-TD / GSM dual-mode terminal, the total time to complete the test before the Olympic Games and optimization of the Olympic Games, the mobile TV feature will not be affected.
