3G full definition _3g exactly what it means.

In this basic knowledge area I've seen an administrator send a complete introduction to WiFi (WAI-FAI) without the more popular 3G, one of which is the internet of things, http://www.chinacloud.cn/show.aspx?id= 2165&cid=17 for everyone more detailed understanding 3G I conveniently in Baidu know excerpt down after all the people say is good enough we don't need to modify the instead of the following is the 3G introduction of the third generation mobile communication technology (3RD-GENERATION,3G), It refers to cellular mobile communication technology which supports high-speed data transmission. The 3G service delivers sound and data information at the same time, at a rate of more than hundreds of Kbps. At present, there are four kinds of standard 3G: Cdma2000,wcdma,td-scdma,wimax. The definition of "3G" (English 3rd-generation) or "Three generations" is the abbreviation of the third generation mobile communication technology, and it refers to the cellular mobile communication technology that supports high-speed data transmission. 3G services can simultaneously transmit sound (call) and data information (email, instant messaging, etc.). Representative feature is the provision of high-speed data services. Compared to the first generation analog mobile phone (1G) and second-generation GSM, CDMA digital Phone (2G), third-generation mobile phone (3G) Generally speaking, refers to the wireless communication and the Internet and other multimedia communications combined with the new generation of mobile communication system, the future of 3G will be combined with the community web site, The combination of WAP and web is a trend, such as the popular Micro-blog site: Big scarf, Sina Weibo, etc. have been added to this application.

The main difference between
3g[1] and 2G is the speed of transmission of sound and data, it can better realize wireless roaming around the world, and deal with images, music, video streaming and other media forms, including web browsing, teleconferencing, E-commerce and other information services, Also consider good compatibility with existing second-generation systems. In order to provide this service, the wireless network must be able to support different data transmission speed, that is, in the indoor, outdoor and driving environment can support at least 2Mbps (megabits per second), 384kbps (thousand bits per second) and 144kbps transmission speed (this number varies according to the network environment).


3G[2] is the third generation of communication network, the current domestic support for ITU to determine three wireless interface standards, respectively, China Telecom's CDMA2000, Chinese Unicom's WCDMA, China Mobile td-scdma,gsm equipment used is time division multiple access, and CDMA using code Division spread Spectrum Technology, Advanced Power and voice activation can provide at least 3 times times the GSM network capacity, the industry will be CDMA technology as the mainstream 3G technology, ITU to determine three wireless interface standards, respectively, is CDMA2000,WCDMA,TD-SCDMA. The former China Unicom's CDMA is now sold to China Telecom, the Chinese telecom has upgraded CDMA to 3G network, 3G main feature is to provide mobile broadband multimedia services.


1995 first generation analog mobile phone (1G) can only voice call;


1996-1997, the second generation of GSM, CDMA and other digital format mobile phone (2G) has increased the function of receiving data, such as receiving e-mail or Web pages;


in fact, the 3G was not born in 2009, as early as 2007 abroad has produced 3g, and China also successfully developed in 2008 China 3G, the downlink speed peak theory can reach 3.6mbit/s (one said 2.8mbit/s), the peak speed can also reach 384kbit/s. It is impossible to say 2G per second on the Internet, of course, the next movie can not be completed in an instant.


Note: G3 is not representative 3G, but the abbreviation of "Guide3", guide has two layers of meaning, verbs represent lead, influence, domination and other meanings, nouns represent the guide, the meaning of the guide. The general idea is to lead two other friends into the 3G era. "3" represents the 3G era of mobile + broadband + Fixed Network + Mobile TV + ... Fusion, bolder conjecture is metaphor China Mobile will surpass the existing 3G concept, provide the network support, terminal, service and so on in the Td-lte era, and lead people into the real 3G life. So G3 is a very complex concept, unless China Mobile has gone back to push "G3" own brand of mobile phones, otherwise the result is only one-strategic brand, will cover the global, Shenzhou, dynamic zone and so on brand business. Major events in May 2000, the International Telecommunication Union officially announced the third generation of mobile communications standards, our country submitted TD-SCDMA officially become international standards, with the European WCDMA, the United States CDMA2000 into the 3G era, one of the three major technologies.


May 24, 2008, the Ministry of Industry and Information technology, the National Development and Reform Commission, the Ministry of Finance issued a joint "circular on deepening the reform of the telecommunications system" to encourage China Telecom to acquire Chinese Unicom (600050, shares) CDMA network (including assets and users), China Unicom and China Netcom merged, China Netcom's basic telecommunications business into China Telecom, China railcom into the Chinese mobile, domestic telecommunications operators from 6 to 3. June 2, 2008, China Unicom to China Netcom proposed to deal with the arrangements for the merger of two companies, a share of China Netcom will be in exchange for 1.508 shares of China Unicom, each share of China netcom US depository Shares in exchange for 3.016 shares of the United States depository shares in China Unicom. At the same time, China Telecom will be a total price of 110 billion yuan to acquire Unicom CDMA network. July 29, 2008, China Telecom Group announced the next three years to invest 80 billion yuan to develop CDMA business, and proposed in three years from the current number of CDMA users from about 43 million to 100 million, then in China Mobile communications market share will reach 15%. October 15, 2008, Netcom Red Chip company in Hong Kong and the stock exchange of New York City retreat. August 2008, the Ministry of Communications issued "on the approval of China Mobile Communication group to carry out trial business work", agreed to China Mobile in the country to establish TD Network and launch trial business. October 1, 2008, China Telecom began to carry out C-net delivery and completed within 60 days. October 15, 2008, the new Unicom company was formally established, the reform of the telecommunications restructuring at the capital market level of work all over. December 22, 2008, China Telecom launched the mobile business brand "Tianyi", section 189th in some provinces and cities into the pilot business, a full transformation of the business operators. December 31, the State Council executive Meeting adopted a resolution, agreed to start 3G licensing work. 3G mobile phone 3G mobile phone is based on mobile internet technology Terminal equipment, 3G mobile phone is the communication industry and the computer industry integration of the product, and the previous mobile phone compared to the difference is too big, so more and more people began to call this kind of new mobile communication products as "personal communication terminals." Even the most layman in the communications industry can easily determine whether a mobile phone is a "third generation" in terms of appearance: third-generation handsets have a large color display, often touch-style. 3G Mobile Phone In addition to the completion of high-quality day-to-day communication, but also for multimedia communications. Users can write and draw directly on the touch screen of a 3G phone and pass it on to another cell phone, which may take less than a second. Of course, this information can also be transmitted to a computer, or downloading some information from the computer, users can use the 3G mobile phone directly to the Internet, viewing e-mail or browsing the web; there will be a number of models of 3G mobile phone with the camera, which will enable users to use mobile phone for computer conferencing, and even make digital camera a "redundant."


3G communication is the introduction of mobile communication service which experienced the first generation of analog technology in mobile communication market, and was introduced into the development of the second-generation digital mobile communication market. In the continuous heating up of Internet Data Service, in the background of constant access rate (HDSL, ADSL, VDSL), 3G Mobile communication system also sees the dawning of the market, which is becoming more and more concerned by telecom operators, communication equipment manufacturers and ordinary users. 3G is China's largest professional 3G mobile phone network Business Services platform registered trademarks. 3G China includes industry, enterprises, products, services and trade functions, is the enterprise in the 3G network to achieve WAP website construction, industry new media dissemination, mobile business operation, wireless timely communication integrated system service platform, the promotion of its industry integration concept and 3G Network wireless communication new marketing model, Form a 3G wireless information network. All of its functional settings and value-added services provide users with perfect, efficient 3G experience, perfect embodiment of the 3G era of strong business connotation.


China has become the world's largest mobile consumer, 2008 China Mobile communications users have more than 600 million, mobile news, cell phone blog, mobile phone mail and other mobile Internet development has been popularized, but all this is only applied to individuals, mobile business applications need more and more urgent, Let enterprises through the mobile Internet to achieve enterprise and user information interaction, and thus carry out a deep, all-round application is today's largest enterprise demand, with the establishment of the Ministry of Industry and Information technology, "3G China" started to become the next step of "information driven industrialization" important measures.


June 2, 2008, the Chinese telecom, China Unicom and China Netcom H-Share company issued a notice, announced the details of telecommunications restructuring, and at this time, the carrier from May 23 due to the telecommunications restructuring suspension, just the past 6 and a half trading day. With the confirmation of Telecom reorganization plan: China Mobile railcom = Chinese Unicom, China Unicom (CDMA network) China Telecom, China Unicom (GSM network), Chinese netcom = China Telecom, thus the Chinese telecommunication operators have formed a tripod. In this telecommunications restructuring, China Railcom was merged into China Mobile Group, became a wholly-owned subsidiary of Chinese Mobile. Then China railcom either fixed-line users or broadband users have been converted into China Mobile users. With the completion of the reform of the "Liuhe three", 3 3G licences will also be issued, and experts estimate that according to the progress of the country or will be issued in the fourth quarter of this year 3G licensing, as soon as the third quarter of next year China will enter the third generation of mobile communications era. will be issued 3 3G card basic use three different standards, TD-SCDMA (Time Division Synchronous Code Division Multiple Access) for China's independent research and development of the 3G standard, has been accepted by the International Telecommunication Union, and WCDMA (Wideband Code Division multiple address) and CDMA2000 collectively known as the world's three major standards of 3G.


under the restructuring of the telecommunications industry, 3G licensing mode is: New China Mobile to obtain TD-SCDMA license, New China Telecom to obtain CDMA2000 license, China Unicom to obtain WCDMA license.


Premier Wen Jiabao December 31, 2008 presided over the State Council executive meeting, agreed to start the third generation of mobile communications license issuance work. It was pointed out that TD-SCDMA, as the third-generation mobile communication international standard, is an important symbol of China's independent innovation in science and technology, and will continue to support research and development, industrialization and application promotion. The issuance of the third-generation mobile communication licence plays an important role in stimulating domestic demand, optimizing the competitive structure of telecom market and promoting the maturity of TD-SCDMA industry chain. The reform and reorganization of telecom enterprises has been completed and the conditions for issuing the TD-SCDMA and WCDMA and CDMA2000 licences of the third generation mobile communication have been provided. The Conference agreed that the Ministry of Industry and Information technology would initiate the issuance of licences in accordance with procedures.


January 7, 2009 14:30, the Ministry of Industry and Information Technology issued 3 third-generation mobile communications (3G) licences for China Mobile, Chinese telecom and Unicom, which marks the official entry of our country into the 3G era. Among them, approval: China Mobile increased based on TD-SCDMA Technical Standard 3G license (TD-SCDMA for our country has independent property rights of 3G technology standards); China Telecom increased 3G license based on CDMA2000 technology, and Unicom has added 3G license based on WCDMA technology. 3G Standard 3G Standard: They are WCDMA (European edition), CDMA2000 (American edition) and TD-SCDMA (China edition).


International Telecommunication Union (ITU) in May 2000 to determine the WCDMA, CDMA2000, TD-SCDMA and WiMAX four major wireless interface standards, written 3G technical guidance Document "2000 International Mobile Communication Plan" (abbreviation IMT-2000). 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 the Frequency division multiple access (FDMA) analog modulation mode, the main disadvantage of this system is low spectrum utilization, signaling interference voice service. The second generation mobile communication system mainly uses the time division multiple access (TDMA) Digital modulation method, enhances the system capacity, and uses the independent channel transmission signaling, causes the system performance to be greatly improved, but the TDMA capacity is still limited, the handoff performance is still imperfect. CDMA system is characterized by its simple frequency planning, large system capacity, high frequency multiplexing coefficient, strong resistance to multipath, good communication quality, soft capacity and soft switching. Here are some of the 3G standards: W-CDMA


Also known as WCDMA, all known as Wideband CDMA, also known as CDMA Direct spread, which is based on the GSM network developed 3G Technical specifications, is the European broadband CDMA technology, which is the same as the broadband CDMA technology proposed by Japan and is being further integrated. W-CDMA's supporters are mainly in the GSM system of European manufacturers, Japanese companies are more or less involved, including Europe and the United States Ericsson, Alcatel, Nokia, Lucent, Nortel, as well as Japan's NTT, Fujitsu, Sharp and other manufacturers. This standard presents the Evolution strategy of GSM (2G)-GPRS-EDGE-WCDMA (3G). This system can be installed on the existing GSM network, for the system provider may be a lighter transition. The acceptance of this new technology is expected to be quite high in Asia, where GSM systems are fairly popular. Therefore W-CDMA has the innate market superiority. CDMA2000


CDMA2000 is a wideband CDMA technology developed by Narrowband CDMA (CDMA IS95) technology, also known as CDMA multi-carrier, which was proposed by Qualcomm North America, Motorola, Lucent and later joined South Korea Samsung all have participated, South Korea is now the leader of the standard. This system is derived from the narrow frequency Cdmaone digital standard, can upgrade from the original cdmaone structure directly to 3G, the construction cost is low. But the current use of CDMA areas only Japan, Korea and North America, so CDMA2000 supporters than W-CDMA more. However, CDMA2000 's research and development technology is the fastest in the current standards, many 3G mobile phones have been first published. This standard proposes the evolution strategy from CDMA IS95 (2G)-cdma20001x-cdma20003x (3G). CDMA20001X is called 2.5-generation mobile communication technology. The main difference between cdma20003x and cdma20001x is the use of multi-channel carrier technology, through the use of three carrier to improve bandwidth. At present, China Telecom is using this scheme to transition to 3G, and has built a CDMA IS95 network. TD-SCDMA


All called time division-synchronous CDMA (TDMA), the standard is set up by the Chinese mainland alone 3G standards, June 29, 1999, China's former Ministry of Telecommunications Science and Technology Institute (Datang Telecom) to the ITU, However, the invention of technology was the ancestor of Siemens, TD-SCDMA has low radiation characteristics, known as green 3G. This standard integrates intelligent wireless, synchronous CDMA and software radios into the world's leading technologies, with unique advantages in spectrum utilization, flexibility for business support, frequency flexibility and cost. In addition, due to the huge market in mainland China, the standard is valued by major telecom equipment manufacturers, more than half of the world's equipment manufacturers have announced that they can support TD-SCDMA standards. The standard proposed that no 2.5 generation of intermediate links, directly to the 3G transition, very suitable for the GSM system to 3G upgrades. Military communication Network is also the core task of TD-SCDMA.


WiMAX


WiMAX's full name is microwave access to the global interoperability (worldwide interoperability for microwave Access), also known as 802 16 wireless metropolitan area Network, is another for business and home users to provide "the Last mile" Broadband wireless connection scheme. The combination of this technology with the need for authorized or unauthorized microwave equipment, due to the low cost, will expand the broadband wireless market, improve the corporate and service provider awareness. WiMAX was officially approved as the fourth global 3G standard after WCDMA, CDMA2000 and TD-SCDMA, at the International Telecommunication Union's plenary meeting on wireless communications held in Geneva on October 19, 2007.

China's 3G Road has just begun, the first universal 3G application is "Wireless broadband Internet access", 600 million of mobile phone users anywhere on the Internet. and wireless internet streaming media business will gradually become dominant. The core applications of 3G include:


1. Broadband Internet access


Broadband Internet access is a very important function of 3G mobile phone, then we can send and receive voice mail, blog, chat, search, download and so on. Now many people think that these functions on the mobile phone to wait until the 3G era, but in fact, the current wireless internet portal can also be provided. Although the current GPRS network speed can not be very satisfactory, but the 3G era, the mobile phone into a small computer is no longer a dream.


2. Mobile office, mobile law enforcement and mobile business


with the increase in bandwidth, mobile office more and more favored. Mobile Office allows office staff can be anywhere with the unit's information system to maintain contact, complete the office function. This includes mobile office, mobile law Enforcement, mobile commerce and so on. Compared with the traditional OA system, mobile Office is free from the traditional OA limited to the shackles of local area network, office staff can access the Government and enterprise database anytime, anywhere, real-time office and processing business, greatly improve the efficiency of office and Law enforcement [3].


3. Video Call


3G era, the traditional voice call has been a very weak function, then video calls and voice mail and other new business is the mainstream, the traditional voice calls will be reduced, and visual impact strong, fast direct video calls will be more popular and rapid development.


3G era is the most talked about is the mobile phone's video Call function, which is one of the most popular 3G services abroad. I believe many people have used QQ, MSN or Skype video chat function, and distant relatives, friends "face-to-face" chat. In the future, rely on 3G network high-speed data transmission, 3G mobile phone users can also "interview". When you use a 3G phone to make a video call, no longer put the phone in the ear, but face the phone, and then put on a cable headset or Bluetooth headset, you will be on the phone screen to see the other side of the image, you will be recorded and transmitted to each other.


4. Mobile TV


from the operator level, 3G license issued to solve a large technical barriers, TD and CMMB standards such as the construction of the development of the entire industry has also been promoted. Mobile phone streaming media software will become the most used mobile TV software in the 3G era, in the video image of the smooth and the quality of the screen constantly upgrade, breakthrough technology bottlenecks, truly large-scale application.


5 Wireless Search


for users, this is a more practical type of mobile network services, but also can make people quickly accept. Using mobile phone search anytime and anywhere will become a common life habit for more mobile users.


6. Mobile Music


in the development of wireless internet mature Japan, mobile music is the most beautiful scenery line, through the mobile phone online download music is 50 times times the computer. 3G era, as long as the mobile phone installed on a mobile music software, can be through the mobile phone network, anytime, anywhere to change the phone to the music box, easy to receive countless songs, download faster, the cost of traffic can almost negligible.


7. Mobile Office [3]


with the increase in bandwidth, mobile office more and more favored. Mobile Office allows office staff can be anywhere with the unit's information system to maintain contact, complete the office function. This includes mobile office, mobile law Enforcement, mobile commerce and so on. Greatly improved the efficiency of work and law enforcement.


8. Mobile Shopping


Many people have the experience of shopping on Taobao, but the mobile mall for many people is still a novelty. In fact, Mobile E-commerce is the 3G era of mobile internet users of the favorite. At present, 90% of Japanese South Korean mobile phone users have been accustomed to spending on mobile phones, even the purchase of rice, washing powder such as daily necessities. Experts predict that China's future mobile phone shopping will have a high-speed growth period, users as long as the opening of mobile Internet services, you can search through the mobile phone product information, and online payment to buy products. High-speed 3G can make the mobile phone shopping become more real, high-quality pictures and video session can make the distance between business and consumers, improve the shopping experience, let mobile phone shopping into a new trend.


9. Mobile Games


and computer games compared to the experience of mobile phone games is not good, but easy to carry, can play at any time, this use of fragmented games is the young people's new favorite, but also a 3G era of important capital growth. The advent of the 3G era, the game platform will be more stable and fast, more compatible, that is, "more fun", like the upgrade version, so that users in the game's visual and effect aspects feel more experienced.


distance from the State Council executive meeting the study agreed to start the 3G license plate only one week, the Ministry of Industry and Information technology quickly to the three major operators issued 3G licences. The Ministry of Industry and Information Technology announces that China Mobile Communications Corporation should be authorized to increase its 3G business license based on TD-SCDMA technology, and China Telecom Corporation should increase its 3G business license based on CDMA2000 technology. China United Network Communications Group to increase the WCDMA technology based on the standard 3G business license.


for operators, 3G licensing means the start of a new round of market competition; for equipment makers, this means that at least 280 billion yuan of investment cake is in front of 3 years, and for users, 3G means that the bandwidth of the mobile phone is soaring, the price is lower. 3G City Beijing More than 2000 sites, is currently filling stations to improve coverage;

G3 Notebook and 3G tariff


G3 Notebook is a new notebook which is launched by China Mobile and several famous manufacturers. It built China Mobile 3G Communication module, also installed a variety of practical office, entertainment software, customers through the G3 online notebook pre-installed G3 with e-line software, can be anywhere wireless access to the Internet, to achieve access to information, entertainment or mobile office needs, very convenient.


At the same time, G3 notebook sales price and subsidy amount is exciting. Let's calculate a bill that would have cost about 3500 yuan to buy a traditional laptop computer, add to buy a 3G wireless internet card about the need to spend more than 1000 yuan, and now only spend about 3500 yuan can have a built-in 3G wireless internet module of the G3 notebook, but also to get the maximum of 2100 yuan of telephone and net fee gift , the equivalent of at present can use about 1400 yuan the price to buy the value about 4500 yuan product. For consumers who are ready to buy laptops, the G3 notebook has undoubtedly brought the perfect opportunity to start.


"G3 notebook Internet fee will be directly in the customer-bound global number of phone calls, believe that this setting provides more convenience to customers" China Mobile Guangdong company said that when the global brand customers buy G3 notebook, you can use the built-in with E-line client, free landing on China Mobile " With E line G3 notebook business to deal with the website ", select the tariff mode, and customers are using the number binding to pay, you can achieve the global call to pay the function of the notebook Internet fee. The person also said that the G3 notebook to achieve a unified national tariffs, regardless of the customer anywhere in the country using G3 notebook Internet, tariffs are the same, will not charge additional roaming fees. Internet fee, there are 50, 100, 200, 300 yuan four type of flow package launched, the monthly excess of the part of the only 0.01 yuan/kb.

in order to tie in with this action, China Telecom will also be launched 70 thousand Yuan 3G wings mobile phone, for users to choose a new package selection.


China Mobile: Technology independent innovation, the first to put into operation


China Mobile 3G Network adopts the China Independent innovation TD-SCDMA Technology, the business brand is "G3". As a domestic technology, TD's development has been vigorously supported by the state, is the earliest operation of the 3G network.


since the 2G era, the implementation of subsidies for mobile terminals has been China Mobile to stick to the old customers and explore new customers an important means. After entering the 3G era, this method will be transplanted to the 3G mobile phones on a large scale. China Mobile insiders have confirmed that with the improvement of TD-SCDMA network, in order to develop users, from next year, China Mobile will significantly reduce the 2G mobile phone terminal subsidy, and transfer the relevant subsidies to 3G mobile phone terminal subsidies.


China Mobile Company's president Assistant has disclosed to the media, the company plans to cost 650 million yuan to set up the TD Terminal special research and Development Fund, and will invest 6 billion to carry on the TD terminal subsidy. The future goal is to launch about 1000 yuan OPhone mobile phone.

China 3G Status


compared with the global 3G development, China 3G is still in its infancy. With the TD-SCDMA network has been in the domestic 10 cities to test commercial and successfully serve the Beijing Olympic Games, the successful completion of operator restructuring and immediately facing the domestic 3G licensing, so that 2008 became China's 3G industry a key year of development. In addition, as of June this year, the total number of mobile phone users in China has exceeded the 600 million mark, Internet users also reached 200 million households. This shows that the rapid development of mobile communications and the Internet has also made China 3G to a higher goal.

The
TD-SCDMA Network was used in the opening ceremony of the Beijing Olympic Games, and nearly 7,000 users in Beijing used the TD-SCDMA network in the evening, with video calls reaching more than 800 times. And China Mobile's 3G network has also experienced the most severe test: in the national stadium and the Olympic center in the opening ceremony, mobile communication network call Peak reached 110,065 times per hour.


compared to China Mobile occasion TD-SCDMA first started the pace of 3G, other domestic operators are also closely related to the deployment of work. It is reported that China Telecom in the takeover of CDMA network and business, that is, the organization of various manufacturers to carry out a number of CDMA testing, including ev-do testing, interoperability testing and business testing. At present, China Telecom to equipment manufacturers of CDMA equipment technology evaluation has been basically completed, the tender work is also in an orderly manner.


And China Unicom in the sale of CDMA network assets and business, not only obtained considerable financial security, but with the rapid development of restructuring and with the WCDMA technology and industry chain the most mature advantages, China Unicom is expected to gain more than 2G era market share, and has embarked on a 3G network planning and construction, Will be opened in the provinces next year commercial. All kinds of indications, 3G in China's early development that has a good result, but also for its future steady development has laid a solid foundation. GSM, CDMA and 3G comparison GSM digital mobile communication system is designed by the Standardization Committee of the major European telecom operators and manufacturers, it is developed on the basis of honeycomb system. including Gsm900mhz, Gsm1800mhz and Gsm1900mhz and several frequency bands. GSM system has several important features: good anti-theft ability, large network capacity, rich number of resources, clear calls, stability is not easy to be disturbed, information sensitive, less dead, mobile phone power consumption is low.


CDMA (Code Division multiple Access) is a new and mature wireless communication technology developed in the branch of digital technology-spread spectrum communication technology. It can meet the market demand for mobile communication capacity and quality, with a high frequency spectrum utilization, good voice quality, confidentiality, low rate, small electromagnetic radiation, large capacity, covering a wide range of characteristics, can greatly reduce investment and reduce operating costs.


3g is the third generation mobile communication technology and is the generic term of the next generation mobile communication system. 3G System is committed to providing users with better voice, text and data services. Compared with the existing technology, the main advantage of 3G technology is that it can greatly increase system capacity, improve communication quality and data transmission rate. In addition, the use of seamless roaming technology across different networks can connect wireless communication systems to the Internet to provide more advanced services for mobile end users.


CDMA mobile phone and GSM mobile phone, compared with the following advantages: CDMA mobile phone use of advanced switching technology: Soft switching technology (that is, switching is first after a good after the interruption), so that CDMA phone calls can be comparable to fixed telephone; using CDMA network, the operator's investment is relatively reduced, This has reserved the space for the reduction of CDMA mobile phone charges; Because of a kind of modulation and multiple access communication method based on the topological frequency communication, the capacity is 10 times times higher than the analog technology, and the GSM network is about 4 times times larger. CDMA based on wideband technology makes video application possible in mobile communication, So that mobile phones from only phone calls and send short messages and other narrow services to broadband multimedia applications.
