Sina technology - May 15 news, according to industry consulting firm said, TD-SCDMA will soon have a breakthrough, China Mobile has asked the TD-SCDMA network in the HSDPA by the end of May to complete the upgrade, which means that TD-SCDMA will be the transmission rate The increase in essence, the theoretical rate of 2.8 Mbps, on improving the external perception of TD-SCDMA network experience will greatly benefit.

TD network upgrade in May

According to the industry-renowned telecom companies, "Three advisory" issued by a latest research report, the Huairou good field test results, China Mobile has asked eight cities in TD-SCDMA network in the HSDPA upgrade by the end of May to complete the work.

It is learnt that the TD-SCDMA upgrade to HSDPA is very value of China Mobile, is the original TD-SCDMA of the peak rate of 384 K has been unable to meet the growing demand for data services. TD-SCDMA require a higher data rate and higher capacity, therefore, in the TD-SCDMA trial network has begun large-scale building today, how to introduce HSDPA technology more and more people's attention.

From 2005 onwards, the vendors began to actively develop TD-HSDPA. In 2006 the ITU World Telecommunications Exhibition in Hong Kong, then Datang and Putian in their booth done a TD-HSDPA 2.8 Mbps rate to the demonstration.

Subsequently, the Ministry of Information Industry Telecom Research Institute, Datang Telecom, ZTE, Putian, the exhibition - such as research institutions and companies are actively promoting the TD-HSDPA standard-setting, since last year, China Communications Standardization Association also announced a succession of TD-HSDPA Some of the relevant standards.

It is understood that the Ministry of Information Industry issued the "peer-to-peer multimedia messaging interoperability between the business network equipment technical requirements" of the 25 recommendations contained in the telecommunications industry standard TD-HSDPA large number of standards, these standards was March 1, 2008 Will go into effect, manufacturers in the TD-HSDPA have a standardized, easy interoperability.

Huairou field test successfully

It is reported that from August last year, the TD-HSDPA on the field testing has caused great concern the industry. At that time, the Ministry of Information Industry Telecom Research Institute has organized a Datang Telecom, ZTE, Putian, Ding Bridge this four equipment manufacturers to conduct outdoor HSDPA test, mainly in Beijing to Huairou, the project test TD-SCDMA system, including core and radio All the equipment side, with a focus on high-speed HSDPA download.

"Three consultation," the report said, Huairou field trials have been ongoing until recently. Concrete progress, in January this year, Datang Telecom, ZTE, Putian, and other equipment manufacturers in the RAN system MTNET Huairou trial network test, the first by the former Ministry of Information Industry Organization's entire network to load the real test. Subsequently, the three companies by the end of January was confirmed by testing HSDPA network, access to the HSDPA RAN network cards, tripod bridge of the unknown.

March this year, the Institute MTNET Huairou in the telecommunications field, Datang Telecom, ZTE, Putian, this four-ding bridge between manufacturers and a TD-HSDPA in the entire network interoperability testing. The results showed that four manufacturers will fully support the HSDPA roaming and switching capacity.

At present, this result has been China Mobile, China Telecom and other operators of recognition, so that the Huairou TD-HSDPA system equipment, field testing almost the end, China Mobile also introduced a next step the network upgrade plans.

According to the industry exclusive that, in addition to China Mobile TD network will be upgraded to HSDPA, China Telecom will also take the TD Baoding network upgrade to HSDPA.

Change the image of the network is good for TD

According to "Three consultation," the report revealed that a number of manufacturers who have been actively preparing for.

Datang Mobile official said, they have to upgrade arrangements and testing work to ensure that the end of May complete the upgrade and operational verification.

Putian relevant parties did not respond to the matter, but said that he has done for the HSDPA upgrade fully prepared, the proposed early in the HSDPA network building, network operators should be concerned about the latter part of the expansion capacity. It is learned that China Putian's HSDPA solution is a multi-carrier frequency design concepts, from a single carrier frequency to multi-carrier frequency of the upgrade process, not hardware changes, software upgrades can only support so that not only meet future demand for HSDPA network expansion , But also effectively reduce the cost of expansion.

In addition, China Mobile TD-SCDMA has been upgraded to the HSDPA example. Early May, South Korea's overseas construction SKT Telecom's first TD pilot network has been upgraded to HSDPA, acceptance testing has been drawing to a close, the results were very good.

Rate in the area, it is learnt that China Mobile TD after the network upgrade to HSDPA, TD-SCDMA network to the peak rate of 2.8 Mbit / s, will improve TD-SCDMA network is good for the image.

However, TD upgrade to HSDPA network equipment and network systems is the progress, terminal manufacturers is ready for the TD-HSDPA terminals also unclear. If only the good network coverage, no corresponding terminals, the user experience will also remain in the original stage, therefore, the current new situation TD terminal manufacturers will put a new test.
