[Edit this paragraph ]3G standard

3G standards: WCDMA (European version), CDMA2000 (American version) and TD-SCDMA (China version).

In May 2000, the International Telecommunication Union (ITU) determined four mainstream wireless interface standards, namely WCDMA, CDMA2000, TD-SCDMA and WiMAX, and wrote them into the 3G technical guidance document International Mobile Communication Plan 2000 (IMT—2000 for short). CDMA is the abbreviation of code division multiple access, which is the technical basis of the third generation mobile communication system. The first generation mobile communication system adopts frequency division multiple access (FDMA) analog modulation mode. The main disadvantages of this system are low spectrum utilization and signal interference to voice services. The second generation mobile communication system mainly adopts time division multiple access (TDMA) digital modulation mode, which improves the system capacity, and uses independent channels to transmit signaling, which greatly improves the system performance. However, the system capacity of TDMA is still limited and the handover performance is still not perfect. CDMA system shows great development potential with its advantages of simple frequency planning, large system capacity, high frequency reuse coefficient, strong anti-multipath ability, good communication quality, soft capacity and soft handover. Here are some 3G standards:

( 1) W-CDMA

Also called WCDMA, wideband CDMA, and CDMA direct spread spectrum, which means wideband code division multiple access. This is a 3G technical specification based on GSM network development, and it is a broadband CDMA technology proposed by Europe. It is basically the same as the broadband CDMA technology proposed by Japan and is being further integrated. The supporters of W-CDMA are mainly European manufacturers with GSM system, and Japanese companies are more or less involved, including Ericsson, Alcatel, Nokia, Lucent and Nortel in Europe and America, as well as NTT, Fujitsu and Sharp in Japan. This standard puts forward the evolution strategy of GSM(2G)-GPRS-EDGE-WCDMA(3G). The system can be built on the existing GSM network and can be easily transitioned for system providers. It is expected that in Asia where GSM system is quite popular, the acceptance of this new technology will be quite high. Therefore, W-CDMA has inherent market advantages.

(2)CDMA2000

CDMA2000 is a wideband CDMA technology developed from narrowband CDMA(CDMA IS95) technology, also known as CDMA multicarrier. It was put forward by Qualcomm North America Company, with the participation of Motorola, Lucent and South Korea Samsung. South Korea is now the leader of this standard. The system originated from the narrow-band CDMAOne digital standard, and can be directly upgraded from the original CDMAOne structure to 3G, with low construction cost. But at present, CDMA is only used in Japan, South Korea and North America, so there are not as many supporters of CDMA2000 as W-CDMA. However, the research and development technology of CDMA2000 is the fastest among the current standards, and many 3G mobile phones have already taken the lead. This standard puts forward the evolution strategy from CDMA IS95 (2G)-CDMA 20001X-CDMA 20003x (3G). CDMA2000 1x is called the 2nd and 5th generation mobile communication technology. The main difference between CDMA20003x and CDMA2000 1x lies in the application of multicarrier technology, which improves the bandwidth by using three carriers. At present, China Telecom is adopting this scheme to transition to 3G, and has built a CDMA IS95 network.

(3)TD-SCDMA

The full name is time division-synchronous code division multiple access, which is a 3G standard independently formulated by Chinese mainland. 1On June 29th, 999, the former Institute of Telecommunications Science and Technology of China Ministry of Posts and Telecommunications (Datang Telecom) proposed to ITU, but the technological invention originated from Siemens, and TD-SCDMA is known as green 3G because of its low radiation. The standard integrates international leading technologies such as smart wireless, synchronous CDMA and software radio, and has unique advantages in spectrum utilization, business support flexibility, frequency flexibility and cost. In addition, due to the huge market in China, the standard has attracted the attention of major telecom equipment manufacturers, and more than half of the equipment manufacturers in the world have announced that they can support the TD-SCDMA standard. This standard proposes a direct transition to 3G without the intermediate link of 2.5 generation, which is very suitable for upgrading GSM system to 3G. Military communication network is also the core task of TD-SCDMA.

[Edit this paragraph] Convenient life in the 3G era

3G will bring new enjoyment to life.

●3G is a video conference in a taxi;

●3G is a soap opera that can't be missed by train;

●3G is an image sent back from the scene to the headquarters for analysis;

●3G is to enjoy your wonderful holiday in Morocco with friends.

China's 3G road has just begun. The first popular 3G application is "wireless broadband Internet access", with 600 million mobile phone users accessing the Internet anytime and anywhere. The streaming media service of wireless Internet will gradually occupy the dominant position. The core applications of 3G include:

1. Broadband Internet access

Broadband Internet access is a very important function of 3G mobile phones. At that time, we could send and receive voice mails, write blogs, chat, search, download ringtones, etc ... Now many people think that the application of these functions on mobile phones will wait until the 3G era, but in fact, the wireless Internet access is already available. Although the current GPRS network speed is not ideal, it is no longer a dream that mobile phones will become small computers when the 3G era comes.

2. Video call

In the 3G era, the traditional voice call is already a very weak function. By then, new services such as video calling and voice mail will become the mainstream, and the traditional voice calling charges will be reduced, but the visual impact will be strong, and fast and direct video calling will become more popular and develop rapidly.

In the 3G era, what people talk about most is the video calling function of mobile phones, which is also one of the most popular 3G services abroad. I believe many people have used the video chat function of QQ, MSN or Skype to chat face to face with distant relatives and friends. In the future, relying on the high-speed data transmission of 3G network, 3G mobile phone users can also "face to face". When you make a video call with a 3G mobile phone, don't put the phone to your ear, but face the phone and wear a wired headset or a Bluetooth headset. You will see each other's images on the screen of your mobile phone, and you will be recorded and sent to each other.

3. Mobile TV

From the operator level, the issuance of 3G licenses has solved a great technical obstacle, and the construction of standards such as TD and CMMB has also promoted the development of the whole industry. Mobile streaming media software will become the most used mobile TV software in 3G era, which will improve the smoothness and quality of video images, break through the technical bottleneck and be truly applied on a large scale.

4. Wireless search

For users, this is a very practical mobile network service and can be accepted quickly. Searching by mobile phone anytime and anywhere will become a common habit of more mobile phone users.

Step 5 move music

In Japan, where wireless Internet is mature, mobile phone music is the most beautiful scenery, and downloading music through mobile phone is 50 times that of computer. In the 3G era, as long as a mobile phone music software is installed on the mobile phone, the mobile phone can be turned into a music box anytime and anywhere through the mobile phone network, and countless songs can be easily stored, with faster download speed and negligible traffic consumption.

6. Mobile shopping

Many people have the experience of shopping on Taobao, but the mobile phone mall is still a new thing for many people. In fact, mobile e-commerce is the favorite of mobile Internet users in the 3G era. At present, 90% mobile phone users in Japan and South Korea are used to spending money on their mobile phones, even buying daily necessities such as rice and washing powder. Experts predict that there will be a rapid growth period of mobile shopping in China in the future. As long as users open the mobile Internet service, they can query commodity information through their mobile phones and pay for goods online. High-speed 3G can make mobile shopping more real, and high-quality pictures and video conversations can bring businesses and consumers closer, improve the shopping experience and make mobile shopping a new trend.

7. Mobile online games

Compared with computer online games, the experience of mobile online games is not good, but it is easy to carry and can be played at any time. This kind of online game that uses spare time is the new favorite of young people at present, and it is also an important capital growth point in the 3G era. After the arrival of the 3G era, the game platform will be more stable, faster and more compatible, that is, "more fun", just like the upgraded version, which will make users feel more experienced in the visual and effect of the game.

Only one week after the the State Council executive meeting agreed to launch 3G licenses, the Ministry of Industry and Information Technology quickly issued 3G licenses to the three major operators. The Ministry of Industry and Information Technology announced that it approved China Mobile Communications Corporation to increase 3G business licenses based on TD-SCDMA technology, China Telecom Corporation to increase 3G business licenses based on CDMA2000 technology, and China United Network Communications Corporation to increase 3G business licenses based on WCDMA technology.

For operators, the issuance of 3G licenses means the beginning of a new round of market competition. For equipment manufacturers, this means that at least 280 billion yuan of investment cake is in front of them in three years; For users, 3G means that the bandwidth of mobile Internet access is soaring and the tariff is getting lower and lower.

[Edit this paragraph ]3G China authorization

On 20091October 7 14:30, the Ministry of Industry and Information Technology issued three 3G licenses to China Mobile, China Telecom and China Unicom, which marked the official entry of China into the 3G era.

Among them, the following were approved:

China Mobile has increased 3G licenses based on TD-SCDMA technology (TD-SCDMA is the 3G technical standard of China's independent property rights);

G3 notebook and 3G charges

G3 notebook is a new notebook jointly launched by China Mobile and several well-known manufacturers. It has built-in 3G communication module of China Mobile and installed various practical office and entertainment software. Customers can surf the Internet wirelessly anytime and anywhere through G3 e-commerce software pre-installed in G3 online notebook, which is very convenient for obtaining information, entertainment or mobile office.

At the same time, the sales price and subsidy amount of G3 notebooks are exciting. Let's work out an account. In the past, it cost about 3,500 yuan to buy a traditional notebook computer, and it cost about 1000 yuan to buy a 3G wireless network card. Now you can own a G3 notebook with a built-in 3G wireless Internet access module for only about 3,500 yuan, and you can get a maximum of 2 1 0,000 yuan for phone calls and internet access, which is equivalent to the current 1, about 400 yuan. For consumers who are ready to buy notebooks online, G3 notebooks undoubtedly bring an excellent opportunity to start.

"The Internet access fee of G3 notebook can be directly deducted from the phone bill of GSM number bound by customers. I believe this setting will provide more convenience for customers." A related person from China Mobile Guangdong Company said that after purchasing G3 notebooks, GSM brand customers can use the built-in e-banking client to log in to China Mobile's G3 Notebook Business Website with e-banking for free, select the tariff mode, and pay by binding with the customer's current number, so as to realize the function of using GSM phone bill to pay the laptop internet fee. At the same time, the source said that G3 notebooks have a unified national tariff. No matter where customers use G3 laptops to surf the Internet in China, the charges are the same, and there will be no additional roaming charges. In terms of Internet access fees, four traffic packages of 50, 100, 200 and 300 have been launched, and the monthly excess is only 0.0 1 yuan /KB. Roughly calculated, you only need to pay about 100 yuan a month, and you can enjoy the service of sending and receiving emails every day and chatting with instant messaging software.

It is understood that G3 notebooks can switch freely between 3G and 2G networks. When customers access the Internet wirelessly in areas with good 3G network coverage, the rate can reach 2.8Mbps, and when switching to 2G network, the rate can reach 460kbps. This setting undoubtedly gives consumers who are still hesitating a reassurance. "In 2003, when China Mobile first started to pre-store phone bills to send mobile phones, I felt very favorable. I bought a customized mobile phone at that time. " Mr. Xu, a customer of Global Connect, said: "Now I have started to customize my notebook, which is so favorable and convenient. Of course, I have to get one right away! "

With the successful experience in the field of mobile phones, it is believed that China Mobile will create a new round of online notebook consumption boom through the strategy of G3 notebook. China Mobile Guangdong Branch said that taking Guangzhou as an example, young consumers with college students as the main body have a high spending power, and the fashionable positioning and preferential price of G3 notebooks are in line with the college students' market, which will soon form a consumption trend on campus. Starting from 12, G3 notebooks can be bought in the designated "Communication 100" service halls in Guangzhou and Shenzhen, and will be sold in major supermarkets such as Gome, Suning and Computer City in the next stage. Consumers will be able to easily experience wireless Internet access in the 3G era.

Advantages of the three major operators.

The advantages of mobile are the original customer base and strong marketing power. Relatively speaking, China Telecom has better network coverage. At present, China Unicom has opened services in 55 cities all over the country, with the current tariff discount of half, and the network speed is slightly faster than that of its competitors, so the three companies have their own advantages.

3G Status in China

Compared with the global 3G development, China 3G is still in its infancy. With the commercialization of TD-SCDMA network in 65,438+00 cities in China and the successful service of Beijing Olympic Games, the successful completion of operator restructuring and the imminent issuance of domestic 3G licenses, 2008 has become a crucial year for the development of 3G industry in China. In addition, as of June this year, the total number of mobile phone users in China has exceeded 600 million, and the number of netizens has reached 200 million. Therefore, the rapid development of mobile communication and Internet also makes China 3G move towards a higher goal.

TD-SCDMA network was used to a certain extent at the opening ceremony of Beijing Olympic Games. Nearly 7,000 users in Beijing used TD-SCDMA network that night, and the number of video calls reached more than 800. China Mobile's 3G network has also experienced the most severe test: when the opening ceremony was held in the National Stadium and the Olympic Center, the peak of network calls of mobile communication reached 1 10065 times per hour.

Compared with China Mobile, which took the lead in launching 3G by TD-SCDMA, other domestic operators are also in full swing to deploy related work. It is reported that after taking over the CDMA network and services, China Telecom organized various manufacturers to conduct a number of CDMA tests, including EV-DO tests, interoperability tests and service tests. At present, China Telecom has basically completed the technical evaluation of CDMA equipment of equipment manufacturers, and the bidding work is also being carried out in an orderly manner.

After the sale of CDMA network assets and services, China Unicom not only obtained considerable financial guarantee, but also with the rapid advancement of restructuring and the most mature advantages of WCDMA technology and industrial chain, China Unicom is expected to gain more market share than in the 2G era, and has started the planning and construction of 3G networks, which will be commercialized in various provinces one after another next year. Various indications show that 3G has achieved good results in the early stage of development in China, laying a solid foundation for its future steady development.
