Measured Chinese 3G standard TD-SCDMA network

April 1, China Mobile in Beijing, Tianjin, Shanghai, Qingdao, Qinhuangdao, Shenyang, Shenzhen and Guangzhou cities in eight official launch of China-made 3G (ie TD-SCDMA) socialization of testing and trial commercial operations, allowing the public free number to purchase 3G and the 3G network terminal equipment. For a time, the whole country, without exception, and to talk about 3G, laid to rest, TD.

 However, looking forward to the hot sales of the scene only focus on a few days to start, and then sank into a complete silence. According to survey data show that, as of April 10, eight cities in TD total sales volume of just more than 2,000 terminals, of which only the TD mobile phone 1800, TD data card to more than 200, much lower than expected sales. Sale terminals mainly concentrated in the lowest prices of several models, such as Lenovo's TD800, LG and Samsung, and several other foreign-branded products, there are many users choice, and expectations of ZTE's most high-end smart phones are seriously unmarketable TD.

What is 3G

The so-called 3G, in fact it's full name 3rdGeneration, the Chinese meaning refers to the third generation of digital communication, which is opposite to the former two generations of mobile communications technology for the purposes of.

Since the advent of mobile phones has gone through a first-generation analogue phones (1G) and second-generation GSM, TDMA and other digital mobile phones (2G) and other two times, and then there data services technologies, such as GPRS, CDMA2001X, EDGE, there are one of these later known as 2.5G and 2.75G technologies.

Measured Chinese 3G standard TD-SCDMA network

Relative first-generation analogue phones (1G) and second-generation GSM, TDMA and other digital mobile phones (2G), 3G standard name for a wide range, such as the ITU defined as "IMT-2000" (International Mobile Telephone 2000) Standard , Europe's telecom giants claimed it as "UMTS" Universal Mobile Telecommunications System. However, their standards are unified to provide mobile terminals in order to speed the move of its data transmission rate of 144kbps, outdoor static or walking rate 384kbps, while the indoor 2Mbps.

 We have said before, 3G standard is not the only, while the number of options. According to the International Telecommunication Union (ITU) to determine the three major wireless 3G communication interface standards are W-CDMA (Broadband Code Division Multiple Access), CDMA2000 (multi-wavelength division multiplexing spread spectrum modulation is contained), and TD-SCDMA (Time Division Synchronous Code Division Multiple Access). WCDMA standard which originated in Europe and Japan, early third-generation wireless research activities, the system in the existing GSM networks to use, for system providers can be a lesser ex-situ transition, the main supporters of the standard in Europe, Japan, South Korea, and America's AT & T Mobile Business Group has selected for its WCDMA third-generation business platform.

CDMA2000 system is mainly dominated by Qualcomm Inc. made in North America, its construction cost is relatively low, the main backers include Japan, South Korea and North America and other regions and countries, China Unicom's new space is the primary criteria used in this program.

TD-SCDMA standard in China with independent intellectual property rights of communication protocol standards, on June 30, 1998 a formal application to the ITU organization. In the November 1999 Helsinki, ITU-RTG8 / 1 and on the 18th meeting in Istanbul in May 2000 the ITU-R plenary session, TD-SCDMA standard was officially accepted as one of the options CDMATDD become the standard one CDMATDD , this is a pioneering mobile communications sector, but also China's third generation mobile communication contribution to development.

 hinese 3G standard in the end is how the real situation like? TD-SCDMA mobile phone just as it did in the legend amazing power? We have organized this field test.

Lenovo TD800
Measured Chinese 3G standard TD-SCDMA network

The parameters measured the terminal, we got a cell phone provided by Lenovo TD800 and Cool 6260, which is the most selling two TD mobile phone market share is high.

 Lenovo TD800 phone is equipped with a 1050mAh lithium-ion batteries, because of instability in the network, making the use of aircraft in the daily course of frequent search network, power-hungry. Under normal use, this piece of the battery is only Nengcheng day and a half, but in a bit after use, fever, more severe.

Cool 6260

Measured Chinese 3G standard TD-SCDMA network

Lenovo TD800 relative to the lower end of positioning, this Coupe is even more high-end 6260 number, which uses dual sim dual standby, for TD-SCDMA and GSM network standard for backward compatibility support, has also adopted WINCE5.0 Smart the operating system kernel. We have been given Coupe 6260 with the 1,700 mAh lithium-ion battery of thicker, supposedly at the expense of body size piece of the battery should be able to bring about the corresponding extension of standby time, but we found in the evaluation process Cool 6260 less than 2 days of standby time, probably in search TD-SCDMA network signal to waste too much power, we hope that the formal listing of models have been improved.

TD-SCDMA measurement Measured Chinese 3G standard TD-SCDMA network

The first: Network Speed

 Many users reflect the TD-SCDMA network is too slow to find, here we had a look at testing, in particular with the GSM signals were compared to see how slow TD's network in the end. Test, the first turn off the phone's wireless phone functions, and then opened mobile phone signal is displayed as the termination of the test cell phone use is Cool 6260, in determining the final seconds of network time of 50'54. The same with GSM networks, the Nokia 5700, let's shut down its wireless signal, and then re-opens, showing the network signal time 4'24 seconds, the gap is quite obvious. So, everyone complained about long TD network network is based.

The second: TD signal area measured

 Measured on the TD signal region, we are mainly from the signal coverage and stability testing. Beijing Mobile announced TD-SCDMA networks in five-ring can be covered within the scope. As we measured, we have to the north of the airport highway exit north road Gao, 3 kilometers away from the North Fifth Ring, testing, and found the signal, you can easily make video calls and calls.

 The second point on the external test sites are selected in the east, Tongzhou Bali Qiao toll station port, 12 kilometers away from the Fifth Ring Road, no TD signal.

 Selected in the third locations in the south of Beijing-Shijiazhuang high-speed long-xiangyangzhen from the Fifth Ring Road 10 km, no TD signal.

Next to City-signal test, first office, the computer world, newspapers, Ring to Ring, the signals under grid. The second point on the South Second Ring Guang'anmen, the signal full. Third Department, Suzhou Qiao, Beijing Polytechnic University, the signal full. Fourth Department, the Zhongguancun area, the signal full.

In addition, when we tested and found considerable instability in TD signal, drift serious, frequent loss of the signal the whole, the consequences is that the call can not be, always remind you of the dial-up number is not in service area. That was rather frequent, has seriously affected the normal phone, not just a model, parameter measurements such problems have a variety of models.

third: Download speed measured

For the actual download speed, we have installed in a notebook Coupe 6260 PCModem procedures and to set Modem in the Cool 6260 under the guidance of the document set-up process was very complex, and a far cry from CDMA. Then, in the phone's "PC Connection" and enter "modem" to open the modem feature, the data cable to connect to the notebook, TD-SCDMA dial is * 98 * 1 #. Also in IDG office environment with TD-SCDMA wireless Internet access, download a size 3MByte the MP3, with around 128 seconds when the average speed of about 25KByte / s.

Fourth: Video calls measured

TD-SCDMA is the most widely used features that a video call, this is also a feature is highly desired. From our testing situation, the video call is basically achieved the expected, although there are also quality smear screen rigid, there is stress, and so flawed, but other areas were able to meet user demand.

 fifth: Standby Time

This parameter measured from several models, most of the battery easier to 1700 milliamperes, the smallest, when there are 1050 milliamperes can be described as a big easy. However, TD's normal mobile phone use, the use of time, no more than two days and kept the search signals, coupled with video calls, will soon deplete the battery, so life is a very thought-provoking questions .

Summary:

TD-SCDMA commercial trial had been almost two months, from our latest available information, China Mobile has stopped the issuance of TD-SCDMA numbers. In other words, even if now you get the TD-SCDMA mobile phones, China Mobile can not go to the previous number, thus can only be used when an ordinary cell phone.

From this evaluation of the actual situation, the first reference measurement models less, and only a few models. The second parameter measured is the mobile phone is still functional in terms of appearance, the products can not be comparable with GSM. Third, is the TD-SCDMA is indeed less than perfect in performance, standby time is short, power-hungry, and imagined a far cry from 3G mobile phones.

Currently, telecom restructuring has already started, the emergency brake on China Mobile's TD-SCDMA is not affected is also hard to say. However, TD-SCDMA as China's 3G standard, the Chinese market is fully capable of prop up one of China's standards. But I want to ask is: China Mobile, you really do in the TD-SCDMA on it?

Five eye-catching hot market, where is the next one Amoi A8

Who will be the next A8? I believe Amoi more anxious than we would like to know. Hong Leyan like a losing gambler, the next one "A8" is its Fanben "trump card." But the world can there be so many "A8", "A8 myth" is just the market conditions under specific historical conditions of a coincidence, not with a can "copy" elements. However, we can create "A9", "A10", success is not only the "A8" This is a road.

So, next year or even next few years, who will have the opportunity to become a new "A8" it?

Hot 1: TD-SCDMA

 Amoi's 3G mobile phone

TD-SCDMA Industry Alliance, as one of the members, and Amoi in the TD-SCDMA research has accumulated a wealth of experience, but also the nation's first TD-SCDMA terminals come up with an alliance member of the real machine. In 2007, an international telecommunications exhibition shows the nine Amoi 3G handsets, including TD-SCDMA standard will have 5 products. For example, like T6, T8 is the flagship product Amoi pushing. T6 is the first with a GPS, TD-SCDMA smart phones, T8 is the EDGE / TD-SCDMA dual-mode dual-pending smart phones. Both models have 2.8-inch large screen, high-capacity battery, 3G video phone and other functions.

 Amoi's TD-SCDMA on the card

Amoi's TD-SCDMA mobile phone research and development, has formed a complete production system, it is also the first foreign operator to offer 3G products in our factory has accumulated rich experience of 3G terminal products. China's 3G standard has been an open secret that it is not, so, Amoi is keen to TD-SCDMA platform, their ambitions to rebuild the glory of the year.

The possibility of 80%


Hot 2: Smart GPS mobile phone

Amoi is starting in 2005 contactless smart phones, in 2006 introduced the E series of large-scale range of products are used in WINDOWSMOBILE operating system products, such as E850, is probably the most expensive WINDOWSMOBILE phone. However, in China's market capacity WINDOWSMOBILE not as big as imagined, as well as the Dopod, Mio old WINDOWSMOBILE handset manufacturers such as run on, so Amoi E series, the amount of product sales is not as expected so much.

eye-catching five Amoi A8 for the next hot market, where is
Amoi E870 smart phone with GPS function

In 2007, the major mobile phone manufacturers GPS, concerned about making the product focus from pure Amoi smartphones smart phone + GPS navigation to be a transfer, such as E870, E72, N6, and so are all smart phones with GPS navigation. At the same time, to N800 Amoi headed several high hopes for its expansion plans in the next year, the products on the market are smart + GPS directions from this point of view, Amoi to next year's "treasure" are pressed in a smart GPS mobile phone.

 Amoi E870 smart phone

GPS mobile phone market next year will be very busy, but Amoi can find a new "A8" ... ...

The possibility of 50%

hot 3: Digital TV mobile phone

Before Amoi has also had a so-called TV mobile phone, but mostly TV-OUT functionality with a fake TV mobile phone, digital TV mobile phone can not be considered true.

China's mobile digital TV standard has not yet conclusive, is to promote mobile TV standard range, mainly including CMMB (SARFT ASTRI wide release), DMB-TH (Tsinghua Legend release), TMMB (the new shoreline introduced) , CDMB (China Association for Standardization released), and TD-MBMS (Datang Mobile launch) and CMB (Huawei launched), etc., in which the department of broadcasting the first four standards are supported (CMMB as a key support for object), the latter two criteria by the Telecommunications system support. The Department of Standards-based mobile data telecommunications network and the mobile phone terminal multimedia processing capabilities, while the criterion used by the Department of Radio and Television Broadcasting Technology + mobile phone chip embedded in ratings.

 TV mobile phone is a short board Amoi

China has more than 530 million mobile phone users, this represents a huge market. Whoever is ultimately become the final standard mobile digital TV for mobile terminal manufacturers have not been developed for this is a huge gold mine, Amoi be able to create one in which the A8 do?

The possibility of 30%

hot 4: Professional camera phone market

When you talk about camera, beginning in 2002 on the standard to high-end phones, but that time can only be regarded as toys, up to 30 megapixels in size and poor quality simply can not be compared with the DC on a par. Cell phone camera from 30 million, 1 million, 2 million, 300 million, 5 million pixels, camera quality is continually improving, especially for people like Sony Ericsson K790c and Nokia N73 camera phone such as the emergence of professional-grade, making a real cell phone camera entered the practical stage, not only prints out the largest 20-inch photos, the picture quality is also almost the same with the low-end DC. Moreover, with the stock camera phone craze, like the N73, K790c of these products are single-paragraph a few more than 1 million sales.

 Extensive product line, but there is no professional camera phone

Unfortunately, the professional high-tech camera phones, not only for high-quality CMOS imaging requirements, to restore the image decoder chip, the internal circuit design, color reduction, shutter design, and so have a very high demand, the current domestic cell phone is also Only Lenovo recently launched a professional i968 camera phones, in terms of quality compared with Europe and the United States the gap is still evident. Therefore, Amoi succeed in the professional market for camera phones out of a road trip to that with its current strength is still a Taimian Jiang.

The possibility of 20%

Hot 5: professional music-phone market

Rely on the selling points of Sony Ericsson Walkman mobile phone market in one fell swoop into the vanguard of the professional music, where music will talk about Sony Ericsson's Walkman phones, with a total sales volume exceeded 15 million units, this is what professional charm. Music phone Amoi has also launched a number of models, but sales of Sony Ericsson's Walkman really pale into insignificance in comparison. Amoi want to learn professional music phone Sony Ericsson walk the path ... ...

 The possibility of 10%

Operators of high tariff is binding, "BlackBerry" in Gate of Life

One source said that two days: Canada's RIM and the mobile terminal in Beijing, Digital China has signed cooperation agreement with the BlackBerry Digital distribution channels into the "individual market in mainland China," and many media claim that this represents the individual users can be used to "BlackBerry" In fact, this is a misunderstanding.

This is a misunderstanding of China's strategic RIM

Personally think that this is yet another misreading of BlackBerry, RIM is a misunderstanding of China's strategy, and the actual situation is that BlackBerry, or BlackBerry, RIM eyeing only the individual user groups, this one in the business users, RIM changed in China what used to be totally dependent on a single operator strategies, rather than the market re-positioning the target user group. If you really let BlackBerry to play multi-media, to push the camera features, go to main music feature, it is estimated three rounds down the iPhone and Nokia have been beaten Mandizhaoya.

In fact, I am more concerned about the story behind the news, such as news that China Telecom and RIM signed a contract and the introduction of BlackBerry for individual users and business users to provide services, including Personal Edition BlackBerry service for the lowest price monthly 80 yuan.

Because of high tariffs is the key to the current situation caused by BlackBerry, or RIM and China Mobile in the two years after marriage finally found the key to open the Chinese market, what is it based on reasonable fee standard to expand the business user market. RIM in China before the silence is not because the wrong direction, nor is it the Chinese market for Push
Mail e-mail needs of small, but useless in the right direction.
not Push
BlackBerry Mail Service is disabled

Take "BlackBerry." In my previous article on many occasions for literacy, "BlackBerry" is not only terminal, BlackBerry BlackBerry system in the terminal is just a part of, another important thing is to BlackBerry service, based on Push
Mail service, not from those flows to the domestic terminal to be judged by BlackBerry BlackBerry, there is no Push
Mail services, BlackBerry and disability without distinction, many of the erroneous views of the Blackberry is such a step by step accumulation, BlackBerry Qi injustice ѽ.

China Mobile drag the BlackBerry in China, promote the progress of the

RIM and China Mobile's co-operation two years, the BlackBerry to now only a few tens of thousands of registered users (there were unconfirmed figures showing that less than 30000). Look at the iPhone, it is the number of parallel imports come in more than two million, this is indeed Mo Fabi. Think, why the BlackBerry service so bad in China, to promote it? I think the most fundamental reason is that its tariff is too expensive, the most low-end actually be 398 yuan, which is only 89 yuan on average ARPU of China Mobile users can be regarded as a high-level users. Is it the wrong move? No, I think the movement strategy is right, occupied only a small part of the pyramid on the high-end users, to earn high profits, as the industry's influence on the market share of the promotion of BlackBerry, BlackBerry's future, and I have nothing to do with? Mobile is very ruthless ѽ.

substitute "thanks" mobile strategy
Provide Push
Mail service providers not just RIM, like China, there is still mail such as service providers, but also cross-platform, in addition to BlackBerry machines, as well as the S60, Windows
Mobile, iPhone and other operating systems, it is impossible BlackBerry ratio. I still post with the person in charge of chatting, had a private assessment of BlackBerry's strategy in China is because China Mobile's strategy to enable them to these third-party service providers have a lot of market gaps and strive to a rapid development time, This is not to thank about moving the "Black Heart" in it? The study of these third-party service providers, marketing strategies, found that tariff is the biggest boost of energy, such as for general business users still post the provision of basic service is free, but for professional business users a service charge is 58 yuan (not including traffic fee), such a price tag in comparison becomes very mobile in terms of competitiveness.

RIM finally came to understand the Chinese market, Gate of Life

RIM in other countries have adopted a strategy with operators to promote their products in China, looking on the China Mobile. However, this partner is too strong, which is reflected in pricing and strong marketing strategy. China Mobile Over the years, only a few tens of thousands of users, Is China's mobile e-mail market will do so small? I have here a group of mail received from the internal data is still so far not yet registered with Push mail
Mail software and services to 1.1 million subscribers, charges users to tens of thousands of households. If you then China Mobile 139 E-mail service providers such as count, China Push
Mail, the number of users is the number of one million level, rather than the single digits, and this number continues to grow each year into exponential growth.

Competitors before intercept, and later other end-products to pursue, in front of us there is such a big piece of cake has to eat, this really anxious about the BlackBerry. I would like to, RIM finally came to understand the root causes of its failure in China, where, so they got this co-operation with Digital China, the intention of not outside the following:

First, change the original business users only for the Group's strategy will account for most of the market share of individual business users into the target market.

Second, up the other two operators, accounting for 20% After all, the number of users, but also can make up their own cross-platform can not be vulnerable at the same time can be reduced in the promotion strategy of China Mobile's right to speak.

Third, the provision of low tariffs and the more common services, expansion of user base, snatch the loss of market share.
RIM road to success in China

Chairman of the Board by Digital China Guo Wei, then God will be the whole network Trader yards BlackBerry sales terminals, allow BlackBerry devices through major channel, laying to various supermarkets, mobile shops, business offices, and so operators channels, as much as possible to enable users to easily purchase BlackBerry devices. To say that alone has the power of Divine will be able to save a RIM, which is purely self-deceiving. In fact the past few years through illegal channels into mainland China by parallel 14 the secret punch countless, the price is also very cheap, the lowest there is only four or five hundred yuan, but because the operator's marketing strategy, these BlackBerry devices network to enjoy BlackBerry services can not only be regarded as "semi-disabled" products, can not really achieve the BlackBerry own characteristics.

Ability distribution for the Shenzhou We do not doubt, for the BlackBerry products we have confidence, but we have heard RIM Wang said China Mobile will launch TD products, but if the paper product to fight a matter of fact do not have the advantages of BlackBerry devices, the most attractive Push only
Mail. Speaking of fundamentals, BlackBerry is still the way to China card in the hands of operators, if the carrier does not meet, RIM is difficult to talk about China's road to success, relying on God yards is also a dead end.

In the final analysis is still a problem, lower tariffs, China is the sole measure for Blackberry firm, which all operators are in the hands of Gate of Life, it's that simple.

5.0 were tested with this set of hardware, software, it also has a strong contrast to the data referential. The following raw data for this test, with bold as the first.

In addition, we can CPU index, Graphics
index options and other tests to see the real parameters measured on the level of hardware phones, such as Asus P535, Graphics
index scores as high as 5806, are the other two products using TI chips more than twice the baseline iPAQ3600 5 times more than sufficient to demonstrate an excellent level of the base hardware. The A501 in the data transmission and throughput advantages are obvious, but in CPU performance and Graphics tests just because of tired by the TI chipset by a score too low. Total benefits, however it is quite obvious.

Please pay particular attention to this test "Pocket Word document open
