China's 3g is in the testing stage, so it is estimated that it will not be so fast.

The future 3G is not a dream.

Because people can't resist the temptation of 3G products, people have predicted 3G products and technologies. Ovam, an independent research and consulting company, released a report, claiming that the market in most regions was mature in 2006. However, most world-class manufacturers have released prototypes of new devices that they think will be the future wireless communication tools.

Analysts of Strategis Group believe that several markets around the world will adopt wireless networks as early as 2002, while the United States will not be able to use this technology until 2004, because Asia and Europe far surpass the United States in 3G wireless technology.

According to another analyst of Strategis Group, Finland, Japan and Britain will launch 3G technology in the market first. Although these countries may not be big markets for wireless Internet services, they will definitely adopt 3G services due to the increasing demand of users. Strategis Group also revealed that a large number of commercial applications of 2 5G and 3G technologies will still take several years to go public, and wireless operators are currently changing their business models to prepare for these services. This will bring a new situation to wireless communication and information.

As for the number of users in the 25G and 3G market in 2006, according to the estimate of Strategis Group, China will have more than 75 million users, ranking first in the world, followed by Japan with about 36 million users, while the United States is far behind, with its 25G and 3G users below140,000.

3G communication technology is getting closer and closer to our life, and its arrival will surely set off a new wave of wireless communication. 3G is an important development stage of personal communication in the future, with milestone and epoch-making significance.

It is estimated that it will take several years for 3G to be commercialized in China. In these precious years, we will vigorously develop GSM from the strategic height of meeting the increasingly fierce competition in the future mobile communication market, constantly introduce new services, and actively and steadily prepare for the evolution to 3G.

The so-called 3G, in fact, is the third generation, which means the third generation digital communication in Chinese. 1995, the first generation of digital mobile phones, can only make voice calls; From 1996 to 1997, the second generation of digital mobile phones appeared, adding 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 handle various media forms, such as images, music and video streams, and provide various information services, including web browsing, teleconference and e-commerce.

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.

According to the standard, when the mobile terminal moves at the vehicle speed, its transmission data rate is 144kbps, when it is stationary or walking outdoors, the rate is 384kbps, and it is 2Mbps indoors. However, these requirements do not mean that the available rate of users can reach 2Mbps, because the indoor rate will also depend on the detailed frequency planning in the building and the close cooperation between organizations and operators.

At present, the 2.5G mobile communication technology that has been put into commercial use is a fusion technology from 2G to 3G. Because 3G is a huge project, involving many complicated layers, it is impossible to connect from the current 2G to 3G at once, so there is a 2.5G between 2G and 3G. HSCSD, GPRS, WAP, EDGE, Bluetoot, EPOC and other technologies are all 2.5G technologies.

HSCSD This is an upgraded version of GSM network, which can greatly increase the transmission speed to two or three times as usual. At present, both M 1 in Singapore and Singapore Telecom use HSCSD system, and the transmission speed can reach 57.6kbps.

Because GPRS has the characteristics of instant online, it is always online for users. GPRS technology also allows service providers to charge according to data transmission volume, rather than simply charging according to online time. This technology cooperates with GSM network, and the transmission speed can reach 1 15kbps.

EDGE is completely based on the current GSM standard, which can not only maximize the function of GPRS, but also provide broadband multimedia services through the current wireless network. The transmission speed of EDGE can reach 384kbps, which can be used for wireless multimedia, e-mail, network infotainment and video conference.

WAP is the first stage product of the combination of mobile communication and Internet, and it is also the most heard. This technology allows users to surf the Internet using wireless devices such as mobile phones and travel between the same stations through small screens. These same stations must also be written in WMl (Wireless Markup Language), which is equivalent to HTML (Hypertext Markup Language) on the Internet.

Prospect of 3G era

Japanese mobile communication giant NTF DoCoMo launched the world's first 3G service based on WCDMA standard on June 10. At present, Asia has become the fastest growing region of 3G, followed by Europe, and the United States is far behind in technical preparation due to lack of enthusiasm. In addition to Japan and South Korea, Thailand and Hong Kong also issued 3G licenses. Taiwan Province Province will soon issue 3G licenses. It is expected that 3G licenses will be issued in the Mainland before the end of the year, and the market is expected to issue two or three photo licenses.

I'm not a professional, I have only a little knowledge at most. If you have chewed it, you may be joking, so you don't want to get too entangled in the meaning of the word "3G". I just want to talk about my own ideas about 3G, and throw a brick to attract jade! Everyone criticized. ...

As we all know, there are three 3G standards: TD-SCDMA, CDMA2000 and WCDMA. Then why two 3G's? Listen to my opinion ... there are several operators in China, and now they are all done by 3 G. It goes without saying that China Unicom and China Mobile have been doing mobile communication for so many years. Do you believe they can still say that when they see such a big piece of meat? Believe me, you can only say that you are a fool:) The other two fixed-line operators, one has a backer (Netcom) and the other has a big mouth (Telecom), so you can sing me down! Foreign irrelevant companies, domestic bricklayers who know something and don't know something, are all rushing into this muddy water ... just one word-chaos!

But I always feel that something is missing. What you are talking about is actually a 3G-3G of the operator. What about our consumers? Where is our consumer's 3G? Are there any commitments from operators? Is there a decision-maker from the national authority? Did they take this into account when planning telecom restructuring and reform? GSM Association, CDG(CDMA Development Organization) and TD-SCDMA Alliance, are there any consumer positions in their beautiful blueprints for their respective 3G standards? Are those so-called 3G really what we need?

Some "fake friends" are going to be "angry", saying that this boy just likes to wrangle! Yes, I don't want to be a fish, so I just want to argue ...)

Operators' 3G is easy to understand: high-speed data transmission, mobile TV, videophone, mobile payment ... There are many things, so I'm too lazy to talk about them. What about the consumer's 3G? I say, of course I can't say it well, but I think with the progress of technology, the rights and interests of consumers and related laws and regulations should also be improved, and "3G" is right. Unharmonious development will have consequences sooner or later!

In the era of 1G, consumers have to spend tens of thousands or even tens of thousands of yuan to enjoy mobile communication services; In the 2G era, consumers began to buy mobile terminals at a price as low as thousands or even hundreds of yuan, access the network for free, and began to enjoy the "gift" phone bill from operators; So what will we get in the 3G era? Operators' 3G planning always avoids this. Then let me have a wild dream ...

First of all, it is a topic that has been called for so long. Let's call for it again today. Consumers in China are always kind and easy to believe what operators say. Such a 1 1 digit mobile phone number is just a string of numbers. Before that, we would rather believe that it belongs to the operator. Two years ago, it was estimated that not many people dared to think about it. But gradually we have a chance to see the world, only to find that the outside world is not like this. In South Korea, in the United States, and even in our own Hong Kong, numbers belong to public resources and do not belong to any operator. Consumers can "defect" to their favorite operators with their own numbers at will. We are ahead of America in some things. For example, China Mobile launched MMS service, which was 10 months earlier than American operators. At present, there are many 200W pixel camera phones in China market, 300W ones are already in use, and 500W ones will be launched soon! The American 200W has just come on the market. But why should we lag behind others in protecting consumers' rights and interests? 10 years ago, telephone users all over the United States could receive address details from operators for free. But in some places, it costs money to go to the business hall to check the fixed-line details in person! ! ! The new government opposes the GDP-only theory and advocates Scientific Outlook on Development. We look forward to change. ...

In addition, interconnection and fair competition are also an old topic. They are all state-owned enterprises, and they are all operating with taxpayers' money. I really don't understand who gave them the courage to engage in "Internet discrimination", interconnection barriers, and digging optical cables to cut wires. To put it bluntly, this kind of behavior is to spend some state-owned assets and prevent or hinder the appreciation of other state-owned assets by illegal means (or 1+ 1 =-2)! ! ! Our taxpayers' money is in our hands. The report of an operator looks good. When the boss gets promoted, shareholders and consumers will flock to him. But they are all playing with our taxpayers' money! Not to mention any state-owned enterprises, as far as competition is concerned, is it necessary for us to experience the "free", vicious and disorderly competition that led to the economic crisis in the early days of capitalism? There is nothing wrong with crossing the river by feeling the stones, but I can only say that it is a crime to go its own way regardless of the lessons learned from the past. ...

Finally, let me talk about the telecommunications law. When Baidu looked at the Telecommunications Law, it only recorded 1 10000, which was much colder than "3G". In such a big country, such a big telecom market, so many domestic and foreign manufacturers are drooling, saying all day that "it will be too late if you don't get on!" . So who cares if the telecommunications law is not enacted? On 3G, it is tens of billions at a time, all of which are people's hard-earned money. It operates without any legal basis. Oh, my God ... I dare not think about it any more!

3G belongs to operators, but it belongs to our consumers! Any reform and reorganization of the telecommunications industry, if its purpose is only to "strike a balance" and meet the interests of certain groups, rather than to promote more comprehensive, effective and reasonable competition and to bring immediate benefits to consumers, will inevitably fail ... Let's say that China Unicom, brick makers, foreign-funded institutional evaluation agencies and some consumers are now flocking to it. Fundamentally speaking, I am not opposed to splitting Unicom. If the reorganization after the split can bring several operators with equal strength and bring more effective and orderly competition than now, then I think few consumers disagree! The question is, can we achieve this goal? I just want to say one thing: is it good for consumers to split Unicom? Now it is quite difficult to fight against China Unicom. Did you artificially make it smaller? What are the consequences? Can consumers benefit from this more unbalanced competition? Or divided into two parts and merged into fixed-line operators! With the advantages of fixed-line operators in the backbone network and their previous misdeeds, the two companies are also quick to kill mobile. Can consumers benefit from this result? To put it bluntly, some enterprises have touched the interests of vested interest groups and moved their cheese. People can't sit still and will "get" you! We consumers sometimes like to follow the trend, but we should be careful whether our own interests can be guaranteed after a gust of wind ... Look at Russia from a distance and listen to the words of western bricklayers and consulting institutions to see if their people have benefited; It depends on China Unicom. In the initial stage of CDMA operation, which famous international "consulting companies" did you find? Has China Unicom benefited? Outsiders always have their own interests, or they need to sell more equipment, or they can't believe it all!

3G should not only be 3G of technology, but also 3G of service, 3G of tariff, 3G of system and rules and 3G of consumers. ...

Two years ago, my idea about the development of mobile communication technology has been realized or is being realized; However, earlier, my expectations for China's telecommunications system, regulations and consumer rights still seemed so far away! We look forward to change!
