Many people talk, 3G technology has been mature foreign direct "Borrowed" Do not give up? As everyone knows, all the waiting, is to give 3G phones branded with a "China and India", the imprint is "TD-SCD-MA".
TD-SCDMA, China's own intellectual property rights put forward and 3G standards, ITU was identified as one of the three main criteria, it can be said to be the world over the past century the only recognized standard in China is expected to bring to China to 1 trillion yuan of profits.
Mobile video, aerial film, mobile FLASH ... ... finally someone taste the flavor of 3G!
The day before yesterday in Beijing, Qingdao, Xiamen and Baoding four major test, the domestic TD-SCD-MA standard of 3G mobile phones to distribute telephone numbers; on the 15th of this month, domestic 3G phones will also be testing a small area in Shanghai to distribute telephone numbers.
Although a limited number of designated areas, but after all, "see and feel" of the.
Why 3G call five to six years in China, but also that "still holds partly concealed"?
China insisted GB 3G
"TD-SCDMA can be described as the last century the only standard in China recognized by the world!"
In 2000, brings together many famous enterprises in the world telecommunication power electronics for the first time sounded the voice of China - International Telecommunication Union (ITU) to accept China's TD-SCDMA standard.
"You know, ITU Member States need more than the United Nations, but if no one adopted Chinese standards, TD-SCDMA is the 'Painted Skin' one." In the eyes of many professionals, the Chinese 3G adhere to national standards, neither fast nor slow, is the correct approach.
Shui Qing Mu Hua (E-Telecommunications) Research senior analyst Chen Zixin told reporters that the United States, Europe, the three standard products and technologies derived from the functional difference is not significant, but the pull of industrial efficiency was very different. United States, Japan, Korea and Europe have mature 3G markets using only their local standards, and rely on standards and technology export, and earned a profit homebuilders.
Like the U.S. standards and European technology frequently coveted 3G "Pure Land", China's third generation mobile communication systems are using the national standard, TD-SCDMA as the "Sheng Sijie."
China-made 3G is not "giving birth"
Early last week, the RDA is located in Shanghai Zhangjiang Micro-winning core communications in line with China has released the 3G standard TD-SCDMA core chip; the day before yesterday, the Chinese 3G in Beijing, Qingdao, Xiamen and Baoding 4 to distribute telephone numbers test.
Insiders of the Chinese 3G industry chain has finally completed the structure, is entering large-scale experiment in midfield, found in China's 3G standard TD chips, base stations, core network and other key technologies being overcome.
"This was my first time taking our own 'phones Way', has run no slower!" Shenzi Xin pointed out that Europe and the United States in the development of 2.5G handsets, the Ins and Outs spent at least ten years. China's 3G is only going around in circles in 2056, called high-speed "innovation race" is hardly "giving birth"!
Why not directly on the 4G?
1G, 2G after him, 3G mobile phone with running, 4G, 5G to lead. This is the circle of domestic 3G technology has been popular "jingles."
Currently, foreign firms, or technical experts frequently raised, "3G mobile phones can not be called a true revolution, and the existing mobile phone features are similar, why not bypass the 3G in China directly on the 4G!"
Hu, senior analyst at China's telecom industry the right to hear this said with disdain smile: Foreign telecommunications or telecommunications companies have already in accordance with the EU and the U.S. 3G standard and be well prepared to rush into the Chinese market, money, how would like the birth of China's 3G mobile phones at home, because "That would take away the world's third-generation mobile communications market 'third world'."
Some experts estimate that dragged on the real 3G licensing in China, will drive China's network operators, electronic equipment, semiconductor industry, content providers and even media outlets and other industries increased exponentially.
Must have their own 3G
Industry, said: "a small cell phone upgrade, will be blowing in the area of the entire national economy in a technological innovation 'Hurricane', the economic benefits generated by at least 100 million yuan."
On the contrary, if China give up "after a long hard to start a" home-made 3G, the end result can only be a profitable network operators, and other industries, "fertile water to flow into others."
One expert said: "Think about buying a cell phone each, each a text message, each read a phone is reported to be marked in the suffix of foreign names, and pay the standard commission, it was too uncomfortable!"
Meanwhile, China would like to catch up with the global electronics industry rapid development of core technology in the future have a greater say and even leadership, can not bypass domestic 3G after all: even if any one technology has been internationally recognized standard, it is " castles in the air "; only through technology applications, real transfiguration commercial products in order to prove a huge" Radioactive ", with commercial energy such as the atomic bomb - led the upstream, midstream and downstream of the relevant technical areas and rapid expansion of industries or even rise a number of multinational corporations in their respective fields, "king."
China's first 4G wireless transmission system last week at the Shanghai Research Center for Wireless Communications by on-site inspection. As the world's largest 4G network field testing environment, technology and standards of their representatives are expected to be held in 2008, the fourth generation of global application traffic collection program stand out.

Shanghai Eyes 3G
15 this month, China-made 3G phones will begin testing a small area in Shanghai to distribute telephone numbers. It's awareness on how? Press to start some investigation.
Most 3G phones are "parallel imports"
China's Nanjing West Road to 绉诲姩钀ヤ笟鍘? a 40-year old female salesperson knew nothing about 3G, the first said, "We have LG, no 3G", then asked, "3G is not the storage size?"
Young salesperson not only familiar with the term 3G, and interviewed two young men is to use 3G mobile phone, but are "parallel." A male salesperson took out their 3G mobile phone, said: "This is a Japanese parallel." He told reporters in Shanghai on the market not selling 3G phone, it was in use, or is bought abroad, or are parallel.
3G features can now spare
"But also no need to buy, Shanghai has not been established 3G networks." He laughs, spent 4,200 yuan bought this phone has been used when the 2G mobile phones, all the 3G features only "backup." Open the flip phone, the screen shows unique shape of "3G" words, upper right corner of the screen has a small camera, open the camera function switch, the screen image immediately the activities of journalists. "Video dialogue", is one of the important functions of 3G phones, but no network, or each other's cell phone is not 3G, this feature can only be furnished.
Shanghai Netcom next month to distribute telephone numbers
"Next month you are to buy, 3G to distribute telephone numbers." He said quietly, Shanghai Netcom to a small area to distribute telephone numbers, also starts with 188, but the number, scope and Telephone Number Service forms is not clear.
"Buy a number, I can feel the 3G it!" Very excited young man. However, when asked what his parallel standard cell phone, he said that W-CD-MA. This is the 3G technology standard in Europe, one of the three standards, and Netcom, "188" is used in TD-SCDMA standard in China - the two can be compatible?
GB and European standard not compatible
"Two standards are not compatible, that number can not be used in the mobile phone." To this end, the reporter sought the advice of experts. Experts say, W - CDMA, CD-MA2000 and the TD - SCDMA is the 3 different standards, their relationship with the GSM and CDMA similar. "It's like buying CDMA mobile phone number must be the same as China Unicom, W-CDMA phones can not use TD-SCDMA numbers." However, the use of different standards of mobile phones, talk to each other no problem.

3G's three "family"
W - CDMA
GSM system is the main supporters of the main European manufacturers, Japanese companies are also involved, including the U.S. and Europe, Ericsson, Alcatel, Nokia, Lucent, Nortel, and Japan's NTT, Fujitsu, Sharp and other manufacturers.
CDMA2000
North America led by a Qualcomm proposed, Motorola, Lucent and Samsung are involved, Korea has become the standard leader. But the CD-MA2000 supporters as W - CDMA Multi.
TD - SCDMA
China developed its own 3G standard, June 29, 1999, China's former Ministry of Posts and Telecommunications Science and Technology Research Institute (Datang Telecom) presented to the ITU. As the huge market in China, more than half of the world to support equipment manufacturers have announced that TD - SCDMA standard.
