What is 3G?

3G stands for 3rd Generation, and its Chinese meaning refers to the third generation of digital communications. The first generation of analog mobile phones (1G) that came out in 1995 could only make voice calls; the second generation of digital mobile phones (2G) such as GSM and TDMA that appeared from 1996 to 1997 added the function of receiving data, such as receiving emails. or web pages; the main difference between the third generation and the first two generations is the improvement in the speed of transmitting voice and data. It can better achieve seamless roaming around the world and process images, music, video streams, etc. Media forms provide a variety of information services including web browsing, telephone conferencing, e-commerce, etc. Good compatibility with existing second-generation systems must also be considered. In order to provide this service, the wireless network must be able to support different data transmission speeds, which means that it can support at least 2Mbps (megabits per second) and 384kbps (kilobits per second) in indoor, outdoor and driving environments respectively. and a transmission speed of 144kbps. (This value will change depending on the network environment).

Compared with the first generation of analog mobile phones (1G) and the second generation of digital mobile phones (2G) such as GSM and TDMA, 3G communication has many names. The ITU stipulates that it is "IMT-2000" (International Mobile Communications). Telephone 2000) standard, European telecommunications giants call it "UMTS" Universal Mobile Telecommunications System.

3G standards, the International Telecommunications Union (ITU) has currently determined the world's four major 3G standards, which are WCDMA, CDMA2000, TD-SCDMA and WiMAX.

[Edit this paragraph] China Telecom Operator Reorganization and 3G Standards

On June 2, 2008, China Telecom, China Unicom and China Netcom H-share companies all issued announcements, announcing Details of the telecom restructuring were revealed. At this time, it had just been six and a half trading days since the above-mentioned operators were suspended due to the telecom restructuring on May 23.

With the determination of the telecom restructuring plan: China Mobile + China Railcom = China Mobile, China Telecom + China Unicom (CDMA network) + China Satcom’s basic telecommunications = China Telecom, China Unicom (GSM network) + China Netcom = China Unicom, thus Chinese telecom operators have formed a tripartite trend.

In this telecommunications reorganization, China Tietong was merged into China Mobile Group and became a wholly-owned subsidiary of China Mobile. So previously, both fixed-line and broadband users of China Railcom were converted to users of China Mobile.

With the completion of the "six-in-three" reform and reorganization, three 3G licenses will also be issued. Some experts estimate that according to the progress, the country may issue 3G licenses in the fourth quarter of this year, and the fastest in the third quarter of next year. China will enter the third generation of mobile communications era. The three 3G cards that will be distributed basically adopt three different standards. TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G standard independently developed by China. It has been accepted by the International Telecommunications Union. It is similar to WCDMA (Wideband Code Division Multiple Access) and CDMA2000 is collectively known as the three mainstream standards of 3G in the world.

According to the telecommunications industry restructuring plan, the most likely way to issue 3G licenses is: New China Mobile obtains the TD-SCDMA license, New China Telecom obtains the CDMA2000 license, and China Unicom obtains the WCDMA license. HH

[Edit this paragraph] About China Mobile 3G number allocation

On April 1, 2008, China Mobile simultaneously launched 3G services in Beijing, Shanghai, Tianjin, Shenyang, Guangzhou, Shenzhen, Xiamen and Numbers were allocated to 8 cities in Qinhuangdao, and TD-SCDMA (hereinafter referred to as TD) social service testing and trial commercialization were officially launched. Under the focus of expectation, wait-and-see, and doubt, China's 3G curtain has finally been officially opened by TD-SCDMA, a domestic 3G standard that has gone through a decade-long technology maturation process. China's 2008 will not only attract world attention due to the Olympic Games, but will also be recorded in history as the "Year of 3G".

It is understood that Beijing has released 15,000 numbers and Shanghai has released 10,000 numbers. However, in just one week, 3G exposed many problems. The signal was not stable enough and calls were intermittent. These problems also made TD the focus of people's attention.

TD has been growing in controversy since its birth. Today, TD has begun trial commercial use, and the real test has just begun.

[Edit this paragraph] About 3G mobile phones

After the network is established, the next problem is the terminal. Many friends don’t know much about 3G, let alone what kind of mobile phones can be used in China’s environment. Many friends even think that just buying a parallel-imported 3G mobile phone can be used in China. In fact, this is not the case. Since the 3G standard currently used in our country is TD-SCDMA, and most of the 3G mobile phones currently on the parallel market are in the WCDMA standard, these products cannot be used in the domestic market now, and like the very popular ones now The iPhone (first generation) and most domestic mobile phones are still stuck in the 2G era.

You need to pay attention to the following points when buying a 3G mobile phone:

1. Whether or not there is a camera has nothing to do with 3G, but most 3G mobile phones have cameras to support video calls, especially Front camera.

2. Foreign 3G technology is incompatible with domestic technology. Even if 3G is turned on in the future, all 3G mobile phones on the market may not be able to use 3G content. Many cities across the country now have 3G test networks. The numbers start with 188 and 189, but only some officials have them. Current 3G mobile phones such as N70/N73 should not be usable after China opens 3G. Our country adopts TD-SCDMA 3G technology with independent intellectual property rights, while foreign countries are all incompatible with W-CDMA and EVDO

3.3G has to be a communication technology standard, and it is made with technology that meets this standard. It is a 3G mobile phone. The technologies that meet this standard include W-CDMA, CDMA-EVDO and TD-SCDMA. TD-SCDMA is China’s independent intellectual property rights. On April 1, 2008, China Mobile has launched in Beijing, Shanghai, Tianjin, Shenyang, Numbers were allocated in eight cities, including Guangzhou, Shenzhen, Xiamen and Qinhuangdao, and TD-SCDMA was officially launched.

3G standards

The International Telecommunications Union (ITU) In May 2000, the four mainstream wireless interface standards of W-CDMA, CDMA2000, TD-SCDMA and WiMAX were determined and written into the 3G technical guidance document "International Mobile Telecommunications Plan 2000" (referred to as IMT-2000). CDMA is the abbreviation of Code Division Multiple Access (Code Division Multiple Access) and is the technical basis of the third generation mobile communication system. The first generation of mobile communication systems used frequency division multiple access (FDMA) analog modulation. The main shortcomings of this system were low spectrum utilization and signaling interference with voice services. The second generation mobile communication system mainly uses the digital modulation method of time division multiple access (TDMA), which increases 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 handover is difficult. Performance is still not perfect. The CDMA system shows great potential for development due to its simple frequency planning, large system capacity, high frequency reuse coefficient, strong anti-multipath capability, good communication quality, soft capacity, and soft handover. The following introduces the several standards of 3G:

(1) W-CDMA

Also known as WCDMA, the full name is Wideband CDMA, also known as CDMA Direct Spread, meaning broadband Code Division Multiple Access is a 3G technical specification developed based on the GSM network. It is a broadband CDMA technology proposed by Europe. It is basically the same as the broadband CDMA technology proposed by Japan and is currently being further integrated. Its supporters are mainly European manufacturers based on the GSM system, and Japanese companies are also more or less involved, including European and American Ericsson, Alcatel, Nokia, Lucent, and Nortel, as well as Japanese manufacturers such as NTT, Fujitsu, and Sharp. This system can be set up on the existing GSM network, making the transition easier for system providers. The acceptance of this new technology in Asia, where the GSM system is quite popular, is expected to be quite high. Therefore, W-CDMA has inherent market advantages. This standard proposes the evolution strategy of GSM (2G)-GPRS-EDGE-WCDMA (3G).

GPRS is the abbreviation of General Packet Radio Service (General Packet Radio Service), and EDGE is the abbreviation of Enhanced Data rate for GSM Evolution (GSM Evolution with enhanced data rate). These two technologies are called 2.5-generation mobile communication technologies.

(2)CDMA2000

CDMA2000 is a broadband CDMA technology developed from narrowband CDMA (CDMA IS95) technology. It is also called CDMA Multi-Carrier and is developed by Qualcomm North America. The leader proposed that Motorola, Lucent and South Korea's Samsung, which later joined, all participated, and South Korea has now become the leader of the standard. This system is derived from the narrow-band CDMAOne digital standard and can be directly upgraded from the original CDMAOne structure to 3G with low construction costs. However, the only regions currently using CDMA are Japan, South Korea and North America, so CDMA2000 does not have as many supporters as W-CDMA. However, the research and development technology of CDMA2000 is currently the fastest among all standards, and many 3G mobile phones have already been launched. This standard proposes an evolution strategy from CDMA IS95 (2G)-CDMA20001x-CDMA20003x (3G). CDMA20001x is called the 2.5th generation mobile communication technology. The main difference between CDMA20003x and CDMA20001x is the application of multi-carrier technology, which increases the bandwidth by using three carriers. China Unicom is currently using this solution to transition to 3G and has built a CDMA IS95 network.

(3)TD-SCDMA

The full name is Time Division - Synchronous CDMA (Time Division Synchronous CDMA). This standard is a 3G standard independently developed by mainland China on June 29, 1999. On the same day, the Telecommunications Science and Technology Research Institute of the former Ministry of Posts and Telecommunications of China (Datang Telecom) proposed to the ITU. This standard integrates today's leading international technologies such as smart wireless, synchronous CDMA and software radio, and has unique advantages in spectrum utilization, flexibility in business support, frequency flexibility and cost. In addition, due to the huge domestic market in China, this standard has attracted the attention of major telecommunications equipment manufacturers. More than half of the world's equipment manufacturers have announced that they can support the TD-SCDMA standard. This standard proposes a direct transition to 3G without going through the 2.5 generation intermediate link, which is very suitable for the upgrade of GSM systems to 3G.

(4)WiMAX

The full name of WiMAX is Worldwide Interoperability for Microwave Access, also known as 802·16 wireless metropolitan area network. A "last mile" broadband wireless connectivity solution for business and home users. Combining this technology with licensed or license-exempt microwave equipment will expand the broadband wireless market and improve awareness among enterprises and service providers due to its lower cost. On October 19, 2007, at the International Telecommunications Union's Wireless Communications Plenary Meeting in Geneva, WiMAX was officially approved as the fourth global 3G standard after WCDMA, CDMA2000 and TD-SCDMA after a majority of countries voted. (/3g homepage)

[Edit this paragraph] UMTS

UMTS was as early as the early 1990s, when the European Telecommunications Standards Institute (ETSI) began to solicit technical solutions for the 3G standard. And ambitiously called 3G technology UMTS (Universal Mobile Telecommunications System), which means universal mobile communications system. Wideband CDMA (bandwidth 5MHz) is recommended as one of its many options. Since then, Japan's active participation has greatly promoted the globalization of 3G standards. In 1998, Japan and Europe reached agreement on the key parameters of the broadband CDMA proposal, making it officially the selected technical solution for the air interface of the FDD (Frequency Division Duplex) band in the UMTS system, and it was therefore commonly known as WCDMA. W stands for broadband, which is different from the narrowband CDMA (bandwidth 1.25MHz) standard originated in North America.

The continuous development of the above-mentioned technical standards is reflected in the four versions of 3GPP's UMTS standards: R99, R4, R5, and R6. A large internal and relatively independent standard system has been formed. WCDMA is the earliest and most complete preferred air interface and is widely used by 3G operators in Europe, Asia and the Americas. (/3g homepage)

[Edit this paragraph] 3G era

Japanese mobile communications giant NTT DoCoMo launched the world's first 3G service on October 1, 2001. Based on WCDMA standard. At present, Asia has become the region with the fastest development of 3G, followed closely by Europe. The United States is far behind in technical preparations because it is not very enthusiastic. In addition to Japan and South Korea, which are the fastest moving, Thailand and Hong Kong, China have also issued 3G licenses. So far, Taiwan has launched 3G services through various telecom operators such as Chunghwa Telecom, Taiwan Mobile, Far EasTone Telecommunications, and Vertex Telecom.

[Edit this paragraph] The current situation of China’s 3G

On April 1, 2008, China Mobile Communications Group Co., Ltd. In 8 cities, the third generation mobile communications (3G) "Chinese standard" TD-SCDMA social service testing and trial commercialization were launched, and its number segment is 157. This marks the official launch of the commercial application of my country's third-generation mobile communications (3G) standard TD. According to reports, the first batch of social business tests will invite 20,000 users from different industries and departments, provide free mobile phones and data card terminals of 2,000 to 4,000 yuan, and give test users a monthly phone bill subsidy of 800 yuan.

Judging from the tariff standards disclosed by China Mobile, the cost of ordinary calls TD is even cheaper than 2G. The TD monthly rental fee is 50 yuan/month, the local basic call fee is 0.40 yuan/minute for the calling party, and the called party is free; the domestic roaming call fee is 0.60 yuan/minute, and the called party is 0.40 yuan/minute; the domestic long-distance call fee is 0.07 yuan/6 seconds ; The SMS fee is 0.1 yuan/message within the network and 0.15 yuan/message outside the network. Receiving is free.

TD's new service - video phone charges are 0.6 yuan/minute for local communication calling and free for the called; 0.9 yuan/minute for domestic roaming calls and 0.60 yuan/minute for the called; domestic long distance 0.10 Yuan/6 seconds. In addition, China Mobile has also launched three TD voice packages and data card packages, with voice rates lower than the current G network level.

After the completion of the second phase of TD network construction, video calls will be available between all provincial capital cities and municipalities across the country, as well as 38 cities including Shenzhen, Dalian, Ningbo, Qingdao, Qinhuangdao, and Baoding.

The procurement bidding announcement recently issued by China Mobile shows that TD-SCDMA network construction will be fully rolled out across the country. It will not take long for 3G users in this city to roam the 3G network in provincial capitals and other major cities across the country, while enjoying high-speed wireless network applications.

TD Phase II Network Bidding

China Mobile recently issued the "Tender Announcement for the Procurement of Wireless Network Equipment for the Phase II Project of China Mobile's Expanded TD-SCDMA Scale Network Technology Application Test Network", stating that it will A tender for the second phase of TD-SCDMA equipment will be launched in the near future.

This 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 and approximately 160,000 wireless carrier fans. This figure is approximately 1.58 times the 14,543 base stations in the first phase of network construction.

There are 10 cities in the first phase of network construction, 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 more than 1,000, with the most reaching more than 3,000. Most cities in the second phase of network construction only have a few hundred base stations, with an average of 800 base stations per city. Experts analyze that although there are many cities in the second phase of TD network construction, they are not as large in scale as those in the first phase of the network, so the initial demand for base stations is also relatively small.

38 cities will be able to use 3G next year

According to the bidding announcement, the second phase of TD network construction covers Shijiazhuang, Taiyuan, Hohhot, Dalian, Changchun, Harbin, Nanjing, Hangzhou, 28 cities including 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 previously stated publicly that the second phase of the network is expected to be completed and put into use by the end of June next year.

After the completion of the second phase of TD network construction, all provincial capital cities and municipalities across the country, as well as 38 cities including Shenzhen, Dalian, Ningbo, Qingdao, Qinhuangdao, and Baoding, will be able to communicate with each other through video calls, achieving a number of 3G typical services.

You can roam in 37 cities and enjoy high-speed communications

Currently, 3G users in this city are using the GSM network when trial commercial users roam to areas not covered by 3G networks. According to the construction progress planned by China Mobile, 3G users in this city will be able to roam the 3G networks in 37 cities across the country by the middle of next year. It will be more convenient to use TD mobile phones or TD data cards to access wireless Internet for work and entertainment in other places.

However, citizens 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 area is mostly in the local central urban area. Citizens roaming to TD cities are expected to have smoother 3G phone calls and 3G Internet access in urban areas, but may experience problems such as weakened 3G signals in local suburbs. At that time, the mobile phone may automatically switch to the GSM network, and calls and text messages should not be a problem, but the use of some 3G services may be affected.

TD will have an unprecedented price advantage starting from September

The Ministry of Industry and Information Technology yesterday approved China Mobile's "Report on Increasing TD-SCDMA Trial Commercial Selective Tariff Plan". From the report It can be seen that TD-SCDMA tariffs will be significantly reduced starting from this month, and Guangzhou, Shenzhen, and Tianjin will pilot it in advance. It is particularly worth noting that in addition to free local calls, TD local calling rates are reduced to 0.22 yuan for the first three minutes and 0.11 yuan per minute thereafter, and the rates are almost reduced to the level of fixed-line rates.

It is reported that the new TD tariff packages launched this time include enterprise packages, family packages, small and medium-sized enterprise office switchboard packages, and campus card packages.

Waiting for 6 years for the final firing of 3G licenses

Time: January 2, 2009 06:42:04 Zhongcai.com

Users will be able to 3G applications with rich experience (picture according to CFP)

The State Council executive meeting recently agreed to start the issuance of 3G licenses, and tens of millions of mobile phone users in Sichuan will benefit

The issuance of licenses has finally fired the starting gun

On the last day of 2008, the issuance of 3G licenses was officially launched. This means that the issuance of 3G licenses, which has been rumored for more than 6 years, is about to be finalized. Rich 3G information applications such as video on demand, video phone, high-speed downloading, and mobile online games will be available to Sichuan mobile phone users in 2009. However, it will take some time for the 3G license to be officially issued due to the need for certain publicity procedures. There was news earlier yesterday that China's 3G licenses were likely to be issued last night. Stimulated by this news, the A-share communications sector rose collectively yesterday.

The issuance of 3G licenses was approved to start

The State Council executive meeting held recently approved the Ministry of Industry and Information Technology to start the issuance of third-generation mobile communications (3G) licenses in accordance with the procedures. The Ministry of Industry and Information Technology also held a special meeting on the same day, requiring active and steady efforts to issue 3G licenses and promote the development of TD-SCDMA. The issuance of 3G licenses that China's communications industry has been waiting for for many years has officially entered the process. The meeting pointed out that TD-SCDMA, as the third-generation international standard for mobile communications, is an important symbol of my country's independent technological innovation. The country will continue to support research and development, industrialization and application promotion. Issuing 3G licenses plays an important role in stimulating domestic demand, optimizing the competition structure of the telecommunications market, and promoting the maturity of the TD-SCDMA industry chain. At present, the reform and reorganization of telecommunications enterprises has been basically completed, and the conditions for issuing third-generation mobile communication TD-SCDMA, WCDMA, and CDMA2000 licenses have been met.

RMB 280 billion in 3G investment to stimulate domestic demand

Li Yizhong, Minister of the Ministry of Industry and Information Technology, previously revealed that 280 billion yuan in 3G investment is expected to be completed in 2009-2010, which is important for coping with the financial crisis

Investment is of great significance in stimulating the economy. He emphasized that the issuance of 3G licenses will be publicized after certain procedures, and each operating company must build 3G networks according to their own development plans to avoid duplication of construction. The reporter learned from the Sichuan Provincial Communications Administration Bureau that Sichuan's communications industry is expected to complete a total investment of 15 billion yuan in planned projects this year, including the network construction and business application of TD-SCDMA, the 3G standard that supports my country's independent intellectual property rights.

□Term explanation 3G, the full name is 3rdGeneration,

refers to the third generation of mobile communications. The first generation of analog mobile phones (1G) that came out in 1995 could only make voice calls; the second generation of digital mobile phones (2G) such as GSM and TDMA that appeared from 1996 to 1997 added the function of receiving data, such as receiving emails or Web pages; the main difference between the third generation and the first two generations is the improvement in transmission speed, which can better realize seamless roaming, process images, music, video streams, etc., and provide services such as web browsing, conference calls, and e-commerce.

□ Plan details According to the previously held national industry

and information work conference, the 3G implementation plan is as follows:

1. Distribution method: China Mobile will receive TD-SCDMA license; China Unicom obtained WCDMA license; China Telecom obtained CDMA2000 license. 2. Market supervision: It is necessary to invest in stimulating economic development and prevent duplication of construction; to create a standardized and fair competition order and not to rob the rich and give to the poor.

□Comparison of operators on the eve of licensing

China Mobile: As of the end of November 2008, there were 450 million mobile phone users. At present, my country has allocated 155MHz working frequency band for TD, and 20M has been allocated for TD large-scale network construction.

China Unicom: As of the end of November 2008, there were 130 million G network users. After the merger with China Netcom, the number of fixed-line users will be 105 million. China Unicom's advantage is that it has obtained the WCDMA standard license with the most mature industry chain, but its disadvantages are the difficulty of integration and its weak financial strength.

China Telecom: As of the end of November 2008, after acquiring Unicom C Network, China Telecom announced that the current user base of C Network was 27.97 million; fixed-line users were 210 million. China Telecom's advantage lies in its mobile fixed-line bundling strategy and financial strength, while its disadvantage lies in the global decline of the CDMA2000 industry chain.

□Market Impact

3G services will be launched within the third ring road in Chengdu this year

The implementation of 3G will first drive the level of mobile phone informatization application of Sichuan people. It is reported that China Mobile will officially open segment 188 in Sichuan to build its 3G business brand; and Sichuan Telecom has also announced the release of number 189 to seize the 3G market. In addition, it is rumored that the 3G number segment allocated to China Unicom is 186. Currently, Chengdu has been selected as a city for the second phase of China Mobile's TD-SCDMA pilot project. Chengdu Mobile will invest 1.2 billion yuan to build 1,030 TD-SCDMA base stations by March this year and optimize the network by June to ensure that 3G is actually launched this year. The mobile communication service covers areas within the Third Ring Road and surrounding universities. The wireless download rate will reach 2.8Mbps, which is 14 times the current rate. On this basis, rich 3G applications such as video on demand, video phone calls, high-speed downloads, and mobile games will be realized.

Starting this month, TD network construction in Chengdu will enter its peak period. In the future, mobile phone users will be able to smoothly enjoy TD services without changing numbers, cards, or registration. They only need to change a dual-mode mobile phone.

The implementation of 3G will drive the entire communications industry chain and bring a wider range of employment opportunities. Deng Yuqiang, CEO of "3G Portal," the country's largest wireless Internet site, said that value-added service companies surrounding telecom operators have been looking forward to the official issuance of 3G licenses for many years, which will drive larger business demand and stimulate the rise of the entire industry. "It is expected that after the issuance of 3G licenses, mobile Internet speeds will be greatly improved, and mobile Internet charges, which have always been high, may drop."

The implementation of 3G has also benefited investors who invest in communication concept stocks to a certain extent. Yesterday afternoon, many stocks in the 3G sector and communications sector rose. As of 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%, ZTE and others also rose to varying degrees. CITIC Securities analyst Zhang Bing said that the telecommunications industry is already at the bottom of historical valuations, and 3G and value-added services will be the substantial driving factors for operator value growth this year.
