What do 3G mobile phones and 3G networks mean?
3G, the third generation, means the third generation digital communication in Chinese. The first generation analog mobile phone (1995) can only make voice calls; From 1996 to 1997, the second generation of GSM, TDMA and other digital mobile phones (2G) have added the function of receiving data, such as receiving mail or web pages; The main difference between the third generation and the first two generations is that the speed of transmitting sound and data has increased. It can better realize seamless roaming around the world, handle various media forms such as images, music and video streams, and provide various information services including web browsing, teleconference and e-commerce. At the same time, we should also consider the good compatibility with the existing second-generation system. In order to provide this service, the wireless network must be able to support different data transmission speeds, that is, at least 2Mbps (megabits per second), 384kbps (kilobits per second) and 144kbps in indoor, outdoor and driving environments respectively. (This value will vary according to the network environment).
Compared with the first generation of analog mobile phones (1G) and the second generation of GSM, TDMA and other digital mobile phones (2G), 3G communication has many names, which are defined by ITU as "IMT-2000" (International Mobile Phone 2000) and called "UMTS" by European telecom giants.
3G standards, the International Telecommunication Union (ITU) has defined four 3G standards in the world, namely WCDMA, CDMA2000, TD-SCDMA and WiMAX.
At 2: 30 pm on June 7, 2009, the Ministry of Industry and Information Technology held a small-scale licensing ceremony, and the 3G license was officially issued. China Mobile, China Telecom and China Unicom obtained TD-SCDMA, CDMA2000 and WCDMA licenses respectively.
Pay attention to the following points when buying 3G mobile phones:
1. Whether there is a camera has nothing to do with 3G, but most 3G mobile phones have cameras to support video calls, especially the front camera.
2. The foreign 3G technology is incompatible with the domestic 3G technology, except Unicom, because Unicom uses the European WCDMA standard. After the opening of 3G, all 3G mobile phones on the market may not fully support all 3G content. At present, many cities in China have 3G test networks with numbers beginning with 188 189, but only some people have them. Now, all N70/N73 mobile phones, such as these 3G mobile phones, have to use Unicom cards after the introduction of 3G in China, so mobile and telecommunications can't be universal. TD-SCDMA is a 3G standard adopted by China Mobile, which has independent intellectual property rights in China, and is not compatible with foreign W-CDMA (3G standard adopted by China Unicom) and EVDO.
3.3G refers to a communication technology standard, and 3G mobile phones are made by technologies that meet this standard. The technologies that meet this standard are W-CDMA CDMA-EVDO and TD-SCDMA, among which TD-SCDMA is China's independent intellectual property right. On April 1 day, 2008, China Mobile officially released its number in eight cities: Beijing, Shanghai, Tianjin, Shenyang, Guangzhou, Shenzhen, Xiamen and Qinhuangdao.
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
The 2008 Olympic Games made everyone enthusiastic about mobile TV, and it became a demand for users to watch the Olympic Games through mobile phones. 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.
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", which, like the upgraded version, will make users feel more experience in the visual and effect aspects 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] China officially opened the 3G era.
China the State Council approved that the Ministry of Industry and Information Technology held a small-scale licensing ceremony at 2: 30 pm on June 7, 2009, confirming the issuance of domestic 3G licenses to three operators, and issued three 3G licenses to China Mobile, China Telecom and China Unicom, which enabled China to enter the 3G era in 2009. Thus, 2009 became the first year of 3G in China, and China officially entered the third generation mobile communication era.
The third generation mobile communication (3G) license in China is the beginning of 3G era in China. The details are as follows: China Mobile obtained TD-SCDMA license, China Telecom obtained CDMA2000 license and China Unicom obtained WCDMA license.
[Edit this paragraph] The current situation of 3G in China
On April/KOOC-0/2008, China Mobile Communications Group Co., Ltd. carried out the social service test and commercial trial of the third generation mobile communication (3G) and "China standard" TD-SCDMA in eight cities, with the number of/KOOC-0/57. It marks the official commercial launch of the third generation mobile communication (3G) standard TD in China. According to reports, the first batch of social business tests will invite 20,000 users from different industries and departments to provide 2,000-4,000 yuan of mobile phones and data card terminals free of charge, and give the test users a monthly telephone subsidy in 800 yuan.
Judging from China Mobile's public tariff standard, ordinary call charges TD are even cheaper than 2G. TD monthly fee is 50 yuan/month, and the local basic call fee is 0.40 yuan/minute, and the caller is free; The domestic roaming call fee is 0.60 yuan/minute, and the called party is 0.40 yuan/minute; Domestic long-distance call charge is 0.07 yuan /6 seconds; The short message fee is 0. 1 yuan/message inside the network and 0. 15 yuan/message outside the network, and the reception is free.
TD new service-local communication of videophone calls 0.6 yuan/min, and the called party is free; Domestic roaming calling 0.9 yuan/min, called 0.60 yuan/min; Domestic call 0. 10 yuan /6 seconds. In addition, China Mobile has also launched three TD voice packages and data card packages, all of which are lower than the current G network level.
After the completion of the second phase of TD network, all provincial capitals and municipalities directly under the Central Government, as well as 38 cities including Shenzhen, Dalian, Ningbo, Qingdao, Qinhuangdao and Baoding, will be able to exchange videophones.
China Mobile recently issued a procurement tender announcement, showing that TD-SCDMA network construction will be fully rolled out throughout the country. 3G users in this city will soon be able to roam 3G networks in provincial capitals and other major cities in China while enjoying high-speed wireless network applications.
TD phase ii network bidding
China Mobile recently issued the Tender Notice for Wireless Network Equipment Procurement of China Mobile TD-SCDMA Expanded Network Technology Application Test Network Phase II Project, indicating that it will start the tender for TD-SCDMA Phase II equipment in the near future.
TD-SCDMA wireless network equipment bidding involves 28 cities including Shijiazhuang and Taiyuan. The second phase of TD network construction plans to build 23,000 wireless base stations, about10.6 million wireless fans, which is about10.58 times of the first phase of network construction.
The first phase 10 cities, including Tianjin, Beijing, Shanghai, Shenzhen and other megacities. It is understood that in these big cities, the number of base stations in a single city is above 1000, and at most it exceeds 3,000. However, most cities with the second phase of network construction have only a few hundred base stations, with an average of 800 base stations per city. According to experts' analysis, although there are a large number of cities in the second phase of TD, the scale of cities in the first phase is not as large as that of cities, so the demand for base stations in the initial stage is relatively reduced.
Next year (2009), 38 cities can use 3G.
According to the tender announcement, the second phase of TD network construction covers 28 cities including Shijiazhuang, Taiyuan, Hohhot, Dalian, Changchun, Harbin, Nanjing, Hangzhou, Ningbo, Hefei, Fuzhou, Nanchang, Jinan, Zhengzhou, Wuhan, Changsha, Nanning, Hainan, Chongqing, Chengdu, Guiyang, Kunming, Lhasa, Xi 'an, Lanzhou, Xining, Yinchuan and Urumqi. Wang Jianzhou, chairman of China Mobile, has publicly stated that the second phase of the network is expected to be completed and put into use before the end of June next year.
After the completion of the second phase of TD network construction, all provincial capitals and municipalities directly under the Central Government, as well as 38 cities including Shenzhen, Dalian, Ningbo, Qingdao, Qinhuangdao and Baoding, will be able to exchange videophones and realize a number of typical 3G services.
Roaming 37 cities and enjoying high-speed communication.
At present, 3G users in this city use GSM network when trying to roam to areas not covered by 3G network. According to the construction process planned by China Mobile, by the middle of next year, 3G users in this city will be able to roam 3G networks in 37 cities across the country, and it will be more convenient to use TD mobile phones or TD data cards to wirelessly access the Internet for work and entertainment in other places.
However, people who are concerned about 3G need to pay attention to the fact that there are only 800 base stations in each city in the second phase of network construction, and the coverage is mostly in local central cities. When citizens roam to TD City, it is expected that 3G phone calls and Internet access will be smoother in urban areas, and problems such as weak 3G signals may occur in local suburbs. At that time, the mobile phone may automatically switch to GSM network, and calls and short messages should not be a problem, but the use of some 3G services may be affected.
Current situation of TD-CMMB:
2008-06-438+02-24, Taier Lab of the Ministry of Industry and Information Technology released the first TD-SCDMA mobile phone test report supporting CMMB function in China yesterday, and two technological achievements independently innovated by China, TD-SCDMA and CMMB, were recognized by professional technology. Another company that obtained the certificate of TD-CMMB test conformity report is Yulong Coolpad. At the same time, the reporter learned from reliable sources in the industry that the Ministry of Industry and Information Technology will issue the first mobile phone network access license to TD mobile phones loaded with CMMB as soon as this week.
More than 30 manufacturers won the bid for centralized procurement of CMMB mobile terminals.
CMMB is a mobile TV standard based on digital broadcasting technology promoted by radio and television system. At present, CMMB mobile TV signals have covered 37 cities in China. The relevant departments specially approved the release of 40,000 TD mobile phones with CMMB (China Mobile Multimedia Broadcasting and Television) mobile TV functions purchased by China Mobile, which enabled the CMMB business of radio and television to be commercialized during the Olympic Games. But at present, all CMMB mobile phones have not obtained the network access license issued by the Ministry of Industry and Information Technology.
As the State Administration of Radio, Film and Television has announced, CMMB mobile TV will be extended to more than 0/00 cities nationwide next year, and will be officially commercialized in the second half of next year at the earliest. Therefore, the State Administration of Radio, Film and Television recently conducted a large-scale collection of CMMB mobile phones, with a collection volume of about one million. Among them, more than 30 mobile phone manufacturers such as Hisense, Lenovo and Tianyu won the bid. However, since the mobile phone access certificate needs to be issued by the Ministry of Industry and Information Technology, these successful mobile phones will be attacked as illegal products if they cannot access the network.
TD mobile phone with CMMB function will get network access certificate.
"The communications industry also has its own mobile TV standards. The competition for standards shows that the distribution of benefits behind it is not uniform, which leads to the delay in issuing a' birth certificate' to CMMB mobile phones by the Ministry of Industry and Information Technology. " A person in charge of a mobile phone manufacturer said.
Because regular manufacturers can't get network access certificates for mobile phones loaded with CMMB services, the "cottage machines" in the market are rampant. Many manufacturers modified the mobile phones that passed the network access test, and added the CMMB TV module to the market without authorization.
The above-mentioned manufacturers said that the TD mobile phone test report loaded with CMMB function was issued by Thiel Lab of the Ministry of Industry and Information Technology to make preliminary preparations for the next step of issuing CMMB mobile phone network access licenses. As soon as this week, it is expected to be the first to issue CMMB mobile phone network access licenses to domestic mobile phone manufacturers, but only for TD mobile phones loaded with CMMB standard.
The industry expects that this move will gradually promote the CMMB function in TD-SCDMA mobile phones.
■ Noun explanation
CMMB is the abbreviation of China Mobile Multimedia Broadcasting, which means China Mobile Multimedia Broadcasting and Television. It is a seamless cooperative coverage broadcasting system combining satellite transmission and ground network. CMMB mainly provides radio and television services for small-screen portable handheld terminals such as mobile phones and PDA, and terminals such as car TV.
At present, the CMMB network has covered more than 100 prefecture-level cities nationwide, which also means that CMMB will be better integrated with TD in the 3G era.

TD has enjoyed an unprecedented price advantage since September.
Yesterday, the Ministry of Industry and Information Technology approved the report of China Mobile on increasing the trial commercial selective tariff scheme of TD-SCDMA. As can be seen from the report, TD-SCDMA tariffs will be greatly reduced from this month, and Guangzhou, Shenzhen and Tianjin will be piloted in advance. It is particularly noteworthy that, except for free local calls, TD local callers dropped to 0.22 yuan in the first three minutes, and then dropped to 0. 1 1 yuan per minute, and the tariff standard almost dropped to the fixed-line tariff level.
It is reported that the new TD tariff package launched this time includes four categories: enterprise package, family package, SME office switchboard package and campus card package.

[Edit this paragraph] The latest 3G attention
3G concept stocks
Companies engaged in the production of 3G mobile phones or providing support for them in the stock market are collectively referred to as the "3G" concept, including operators and manufacturers. For example, Unicom, ZTE, Bird mobile phone, etc.
[Edit this paragraph] After 6 years of 3G license issuance, the starting gun is finally sounded.
Time: 065438, 2009+06:42:04, 200912 October.
CFP said that users will be able to experience rich 3G applications this year.
The the State Council executive meeting recently agreed to start issuing 3G licenses, which will benefit tens of millions of mobile phone users in Sichuan.
The last starting gun for license issuance.
On the last day of 2008, 3G licensing was officially launched. This means that the issue of 3G license issuance, which has been rumored for more than six years, will soon be settled. Rich 3G information applications, such as video on demand, videophone, high-speed download and mobile online games, will meet mobile phone users in Sichuan in 2009. However, due to the need for publicity through certain procedures, it will take some time for 3G licenses to be officially issued. Earlier yesterday, it was reported that China's 3G license was likely to be issued last night. Stimulated by this news, the A-share communication sector rose collectively yesterday.
3G license issuance allowed to start.
At the executive meeting of the State Council held recently, it was agreed that the Ministry of Industry and Information Technology would start the issuance of 3G licenses according to the procedures. The Ministry of Industry and Information Technology also held a special meeting on the same day, demanding that 3G licenses be issued actively and steadily to promote the development of TD-SCDMA. China telecom industry has been looking forward to the official entry of 3G license issuance for many years. The meeting pointed out that TD-SCDMA, as the international standard of the third generation mobile communication, is an important symbol of China's independent innovation in science and technology, and the state will continue to support research and development, industrialization and application promotion. Issuing 3G licenses plays an important role in stimulating domestic demand, optimizing the competitive structure in the telecom market and promoting the maturity of TD-SCDMA industrial chain. At present, the reform and reorganization of telecom enterprises have been basically completed, and the conditions for issuing third-generation mobile communication TD-SCDMA, WCDMA and CDMA2000 licenses have been met.
280 billion 3G investment to stimulate domestic demand
Li, Minister of Industry and Information Technology, previously revealed that 3G investment in 2009-20 10 is expected to reach 280 billion yuan, which is of great significance for coping with the financial crisis and stimulating the economy through investment. He stressed that the issuance of 3G licenses will be publicized through certain procedures, and all operating enterprises should build 3G networks according to their respective development plans to prevent redundant construction. The reporter learned from Sichuan Communications Administration that it is estimated that Sichuan communications industry will complete the planned project investment of 654.38+0.5 billion yuan this year, including the network construction and business application of 3G standard TD-SCDMA supporting China's independent intellectual property rights.
□ Noun explanation 3G, full name is 3rdGeneration,
Refers to the third generation mobile communication. The first generation analog mobile phone (1995) can only make voice calls; From 1996 to 1997, the second generation of GSM, TDMA and other digital mobile phones (2G) have added the function of receiving data, such as receiving mail or web pages; The main difference between the third generation and the first two generations is the improvement of transmission speed, which can better realize seamless roaming, handle images, music and video streams, and provide services such as web browsing, teleconference and e-commerce.
□ According to the details of previous national industry programs.
The 3G implementation plan is as follows:
1. Distribution method: China Mobile will obtain TD-SCDMA license; China Unicom obtained WCDMA license; China Telecom obtained CDMA2000 license. 2. Market supervision: we should invest to stimulate economic development and prevent redundant construction; Create a standardized and fair competition order, and do not rob the rich to help the poor.
□ operator comparison on the eve of licensing
China Mobile: By the end of June 2008, the number of mobile phone users had reached 450 million. At present, China has allocated 155MHz working frequency band for TD, and the TD scale network construction has been allocated to 20M.
China Unicom: By the end of June 2008, G users165438+300 million. After the merger of Netcom, the number of fixed-line users was 65.438+0.05 billion. The advantage of Unicom is that it has obtained the most mature WCDMA standard license in the industrial chain, while the disadvantage is that it is difficult to integrate and its financial strength is weak.
China Telecom: At the end of June 2008, 1 1, after China Telecom acquired Unicom's C network, it was announced that the current user scale of C network was 27.97 million; Fixed telephone users 2 1 10,000. The advantage of China Telecom is the bundling strategy and financial strength of mobile fixed network, and the disadvantage is the global decline of CDMA2000 industrial chain.
□ Market impact
This year, the Third Ring Road in Chengdu opened 3G service.
The implementation of 3G will first promote the application level of mobile phone information in Sichuan. It is reported that China Mobile will officially open section 188 in Sichuan to build a 3G business brand; Sichuan Telecom also announced the number of 189 to seize the 3G market. In addition, it is said that the 3G segment allocated to China Unicom is 186. At present, Chengdu has been selected as the second phase pilot of China Mobile TD-SCDMA. Chengdu Mobile will invest1.200 million yuan to build 1.030 TD-SCDMA base stations before March this year, and carry out network optimization before June to ensure that 3G mobile communication services will be really launched this year, covering areas within the Third Ring Road and surrounding universities, and the wireless download rate will reach 2.8Mbps, which is 1.4 times the current rate. On this basis, rich 3G applications such as video on demand, videophone, high-speed download and mobile games will be realized.
[Edit this paragraph] About TD network
TD-SCDMA network of China Mobile will enter the peak period in 2008. In the future, mobile phone users can enjoy TD service only by changing a dual-mode mobile phone without changing the number, card or number.
The implementation of 3G will drive the whole communication industry chain and bring more employment opportunities. Deng Yuqiang, CEO of 3G Portal, the largest wireless Internet station in China, said that the value-added service enterprises around telecom operators have been expecting the official issuance of 3G licenses for many years, which will drive greater business demand and stimulate the rise of the whole industry. "It is expected that after 3G licensing, the Internet access speed of mobile phones will be greatly improved, and the Internet access cost of mobile phones, which has remained high, may decrease."
The implementation of 3G also benefited investors who invested in communication concept stocks to some extent. Yesterday afternoon, many stocks in 3G and communication sectors rose. At the close, Eastcom Peace rose 5.89%, hisense electric rose 4.75%, ST Datang rose 4.66%, ZTE rose 2.84%, China Unicom rose 0.8%, and ZTE also rose to varying degrees. Zhang Bing, an analyst at CITIC Securities, said that the telecom industry is already at the bottom of historical valuation, and 3G and value-added services will be the substantial driving factors for the value growth of operators this year.
Relevant departments of the Ministry of Industry and Information Technology began to issue the first batch of CMMB TD mobile phone access cards, and Hisense and Yulong Coolpad took the lead in obtaining CMMB TD mobile phone licenses.
It is understood that with the lifting of the ban on the CMMB mobile phone network card, TD+CMMB terminals of regular brand manufacturers will be put on the market on a large scale, which will promote the rapid standardization of the CMMB mobile phone industry and reverse the situation that cottage machines are flooding the market.
Experts pointed out that this release is only for TD mobile phones with CMMB function, mainly considering supporting domestic 3G technology and further expanding the application space of TD. Let users enjoy more business functions on TD mobile phones.
On the 7th 14: 30, the Ministry of Industry and Information Technology issued three 3G licenses for China Mobile, China Telecom and China Unicom. Among them, China Mobile obtained TD-SCDMA license, China Telecom obtained CDMA2000 license and China Unicom obtained WCDMA license.
[Edit this paragraph] About 3G licenses
On 20091October 7 14: 30, the Ministry of Industry and Information Technology issued three 3G licenses for China Mobile, China Telecom and China Unicom. Among them, China Mobile obtained TD-SCDMA license, China Telecom obtained CDMA2000 license and China Unicom obtained WCDMA license.
Li, Minister of Industry and Information Technology, Guohua, Vice Minister, Zhang Xinsheng, Deputy Director of Science and Technology Department, and other leaders held the awarding ceremony with core executives such as Wang Jianzhou, Chairman of China Mobile, Chang, Chairman of China Unicom and General Manager of China Telecom.
3G in Network Language
In network language, 3G refers to onion, ginger and garlic. They are three common seasonings in life, meaning trivial things, which are equivalent to what people call "trivial". For example:
"BS, LS in 3G for half a day, B not BT? 」
Can also be extended to endless debates and war of words on the forum, as verbs, such as:
"Netizens have been thinking about the Sanlu incident for almost half a year. 」
With the development of 3G mobile communication technology in China, the network language "3G" gradually spread on the Internet.
[Edit this paragraph ]3G investment is expected to stimulate nearly 2 trillion yuan of social investment.
Li, Minister of Industry and Information Technology of China, said that according to the respective development plans of telecom operators, the 3G direct investment in 2009 and 20 10 is estimated to be about 280 billion yuan. Some experts believe that 3G investment for three years can boost social investment of nearly 2 trillion yuan, which will help boost China's economic growth.
"The investment-driven effect of 3G license issuance is obviously different from that of national infrastructure. National infrastructure construction such as transportation and energy requires a lot of government investment, and the issuance of 3G licenses will immediately attract social funds, because the market has long expected the issuance of 3G licenses. " Chen Jinqiao, deputy chief engineer of China Telecom Research Institute, said.
After the 3G license is issued, a communication industry chain including 3G network construction, terminal equipment manufacturing, operation service and information service will be formed, which will play an important role in expanding domestic demand and stimulating the economy.
"Although the absorption of ordinary workers is not as obvious as infrastructure construction, the capital and technology-intensive nature of the 3G industry determines that it will be very attractive to some mental workers.
