This conference is devoted to discussing the development trend of WiMAX technology and related hot issues, discussing the latest progress of WiMAX technology development around the world, and learning from foreign experience; At the same time, a two-day exhibition will be held to show the latest progress of WiMAX technology and products of domestic and foreign communication manufacturers. Bubble net broadcast the conference live. The following is a wonderful speech by Professor Song Junde from Beijing University of Posts and Telecommunications:
Yu Yang: Thank you very much, Ms. Emily Green. Now let's enter the speech stage this morning. The first one should be Zhou Baoxin, who is the vice chairman of China Standardization Association. He should speak, but he has to attend another meeting, so we are very lucky to have Song Junde here to speak on his behalf. Song Junde is a member of China Mobile Technology Association and a participant of MI. It should be said that he has published 36 publications. He should be a very famous person in China, so now we have Professor Song Junde!
Song Junde: Good morning, everyone! I got this job temporarily yesterday afternoon, because I just attended an international seminar in Shanghai the day before yesterday. Of course, everyone will suffer, because I'm sure I don't speak as well as Mr. Zhou Baoxin, so I wronged everyone.
I didn't tell me until I got here today that I wanted to tell you more about WiMAX in China, so my manuscript also told it, and I can do whatever I want. Besides, I didn't know this topic until this morning, so I knew I wanted to discuss Asian issues, so I'm sorry that I might waste 30 minutes, so I just made up a few words.
I thought, why should I say such a topic? Talking about broadband wireless mobile communication? In fact, the meaning of my topic, the first one, is about broadband wireless, and the second one is about our current 3G SSPA, which is about 10 megabit. We call it broadband. In China, the width is about this size, and the width is a little wider. Of course, I don't think this word will last long. I believe everyone here loves WiMAX very much. Everyone wants us to say that WiMAX is the best now, and the future world must be WiMAX.
Personally, I can say that I started to do 3G from China Mobile Communications, and then why did I use one third of my research power to do WiMAX and so on? That is, I see that this is an inevitable and very good direction in the future, which I will talk about later. So why not talk about WiMAX alone today? But what about the content of the two topics together? I think our country is advocating social harmony, so our network should advocate integration, not integration. We are prone to quarrel from the beginning. If we integrate, our radio and television information department will quarrel, and we can't do many things that are very beneficial to the people. So if we want a harmonious society, we must first integrate the network, and ask our technicians here to shake hands with technicians in another field to provide people with good services, good terminals and good networks. Here it is.
As we all know, the situation in Asia and the whole world is being discussed at home and abroad, especially today. Just now, the host told me that it goes without saying that everyone here knows this, so I avoided it. But why should I say a few words? Because we accepted it last year, I am also the executive vice president of Beijing Communication Association. Since we are talking about China, I'm sorry, because I was told to talk more about China ten minutes ago, because I was told to talk more about the world.
What about WIFI and WiMAX in China now? The Ministry of Information Industry of China once wanted to develop a batch of 802. 1 1 about six or seven years ago, four or five years ago. At that time, AB, not G, covered some cities with this technology. At the same time, from the government's point of view, it hopes to develop a group of small operators to compete with our six major operators. So this is the distribution of 3.5G at that time. As we all know, the first batch of 3.5G frequency acquisition did not include major operators such as China Mobile and China Telecom, which was the purpose of the government at that time.
However, after our practice, 100 people got the frequencies of different cities and regions, but none of them succeeded. Up to now, we have only left a few small operators, and it has not become too big. I'll talk about why later. In the second batch, China Mobile, China Telecom and other big operators also got 3.5G, and like China Mobile, they also laid wireless technology all over the country. I'll talk about their operation later.
How about WiMAX in China? When WiMAX comes out, I believe there are not only equipment manufacturers but also operators in China. If there are China Mobile, China Netcom and China Telecom present, I think everyone knows that they all like this technology very much. It's not that operators don't like WiMAX. Later, I will talk about the problems encountered in the development of WiMAX in China. It is said that this is a good technology, but they have their own ideas. For example, China Netcom likes to use WiMAX, while South China can use WIFI, that is, its subscriber line can't go deep into the areas where users go, so it can be used to develop customers. China Telecom hopes to use wireless technology in the area north of the Yangtze River controlled by China Netcom. Of course, these frequencies are not available in China at present, and WiMAX has no official nationally recognized frequencies. I hope this sentence.
Because when he sent you the usage frequency of 3.5G, he said broadband wireless access. Of course, you can use WIFI after WiMAX, but naturally everyone thinks that WiMAX will use 3.5G first in China. Later, our frequency management department published an article saying that fixed broadband wireless access did not refer to WiMAX, so now in China, we see that some areas are developing WiMAX 16D with 3.5G, and some areas even use 1.8G, so a big problem in developing WiMAX in China now is that there is no frequency. According to the original plan, the frequency of WiMAX in China should be discussed before the end of last year. According to the plan of the Sports Commission, this matter has been delayed, because our country is now concentrating on promoting TD-CDMA. But even so, everyone's enthusiasm for WiMAX has not diminished. As you know, the big move is that they have a big plan for wireless broadband coverage in Tianjin Tanggu Technology Development Zone. The general framework agreement is an agreement signed by the Ministry of Information Industry and the Tianjin Municipal Government. Of course, there will be some specific discussions on the specific implementation. Beijing is a research topic that I am responsible for, and it is not related to the Internet, but I can tell you that a plan called information benefiting the people is being promoted in the suburbs of Beijing. I didn't bring this plan with me today, because I was told to talk about the situation in China temporarily. You can see from those photos that the suburbs of Beijing, especially farmers, are now using broadband wireless access technology. For example, you can go to Pinggu. I went to a village. The antenna of this village, the 30-meter-high antenna is welded by the village head and the village branch secretary, a 30-meter-high tower, and then a WIFI antenna is installed on it, realizing the coverage of the whole village. Farmers don't have to pay the information fee, but the village head has to pay the information fee to Ge Hua, because the optical cable goes there. Farmers only need to buy their own computers, but in this village, there are more computers than televisions, which is different from many rural areas in China. Many rural areas are dominated by televisions, and there are fewer desktop computers. What do they do with this? They get information from the Internet. For example, they gave a vivid example. They used to grow Dutch beans, which cost only fifty cents a catty. Later, they can search the prices of Dazhong Temple and farmer's camp in Beijing. When they found this thing, 2.5 yuan, they said that you exploited us too much, and we only sold 2 yuan. This time, farmers earn more per catty 1.5 yuan. Of course, they also cited many things about medicine, education and so on.
There are many small family hotels in the suburbs. Now many of us love to go to the country on weekends, but how do we know how many beds there are in his house and what are his specialties? They all made information on WiMAX, WIFI, and posts. You can find the hotel directly, and farmers get rich by these. Now Beijing has a big plan to promote broadband information services in all suburbs. This year, the government will pay part of the money, the county government will pay part of the money and the village government will pay part of the money. People have a light burden, so everyone can afford this information.
Of course, this plan also includes some places where optical cables can't reach now. We recommend combining WiMAX with WIFI. Of course, in the city, we still have the problem of the 2008 Olympic Games. This also needs to solve the problem of backpackers, that is, many spectators and athletes come with notebooks and want to open them wherever they go. This is also the next step that Beijing will consider for the 2008 Olympic Games. Of course, China Mobile will be responsible for the whole stadium.
If you go to Jiangnan, Shenzhen and Guangdong, you will find that some small towns are signed by individual entrepreneurs and town governments. They use WiMAX to cover a town, and after two or three years, they can collect some income and recover their investment. So what I mean by this statement is that although the official frequencies are not included in China, especially WiMAX 16 1, they are mobile or will be operated by operators in the future. Although they have not entered the formal stage, they are slowly developing.
Let me talk about the development of WiMAX in China. Why can't we discuss WiMAX separately? In fact, everyone should use their brains. These two things are the same in China and all over the world. They come from two roads. One is based on Intel. As we all know, Intel was originally a network of poor scholars, a free, equal and casually connected network, which did not guarantee security and QS. It was not until the 1990s that Intel had its own business. Let's look at 1G, 2G, 3G, which are actually from the original telephone network. Although China Mobile is also separated from China Telecom, this system has strict operators. To be honest, the premise of operators is the government. This network is such a government plus analog network. Although all countries are reforming and pushing for non-nationalization, telecommunication networks are always strictly controlled by operators. In other words, it takes your user one minute to make a phone call on it, and one minute and five seconds is two minutes, which is very strict. If you want to enter, you must go through a lot of registration procedures. This model will bring great profits to the operator, so he will have a lot of money to upgrade and improve.
On the other hand, our WIFI and WiMAX started to work by adding an IP from the Internet or ADLS, so we started to make phone calls. The operator found out why you walked past my website without paying, so you started to make phone calls, so this is a car on two roads, and there has always been a contradiction. I just said that China Mobile likes WiMAX, but it has its own way. China Mobile discusses WiMAX very well, and this technology is very good. We want to use it, but we should use our unified management platform to manage it. Two or three years ago, it was said that 200 million to 300 million networks were in the whole country at the same time, and only one laptop could be connected at a time. It is too expensive and unprofitable, so operators don't like it very much. WiMAX is operated by operators and can only be done if it is profitable. So what we are going to discuss is the future business model after WiMAX integration, which is to make money for operators. Operators won't lay your network without making money. Your Intel network also depends on the store. We don't have a separate network laying company, so there should be an average profit in the middle. So this is the basis for us to discuss all issues, but have these two roads always gone hand in hand? I don't think it's possible. Why?
I got a mobile phone because of the common people. I don't want to know which operator it comes from, whether it's wireless or wired, and how many miles it took to reach me. I don't care. I only care that the other party can't tell me clearly. Did I see the pictures sent by the other party? Did I download the movie? In this case, our technology should serve the people, so in the end, I think WiMAX, no matter what opinions we have here, is a way of integration, which is integrated into the terminals of the people and into the service providers of the people. This is what we have studied with Intel for three years. We hope to integrate not only terminals, but also services and services. This is a simple integration. For example, our terminal is WiMAX here and 3G here, which is totally acceptable. This integration is easy, and our services can also come in.
But network integration is a little bit more difficult, and there are many conversions between the two networks. We have done a lot of research and experiments, which prove that it is possible and within the acceptable range of people. In this case, it is easy to see the integration of services, networks and terminals. The last thing that is difficult to achieve is the integration of business models, which is free. Time is limited today. If you are interested, please leave the manuscript for everyone to read.
Let's look at the relationship between WiMAX and LTE. The first two pictures are familiar to everyone. The biggest advantage of WiMAX is bandwidth. Although it can't exceed 100 km, it can still move 80-90 km, thus forming competition. I have a large bandwidth, can move, and the equipment is cheap. At this time, everyone knows that 3G is developing rapidly, SHPA is realized three years ahead of schedule, and SHPA is also realized several years ahead of schedule. In turn, these two companies. Now WiMAX wants to enter this big family. What big family? Entering the IMT2000 family can change the illegitimate child status, get the official frequency, and officially operate in all countries in the world, which is a very important aspect.
Secondly, it has a great advantage, that is, it uses the patent pool to avoid a company occupying an absolute majority of patents to control the development of this technology. This is WiMAX's strategy. When I came here, I think it should be admitted that the earliest terminal of WIFI and WiMAX based on the Internet was PC, and then there was a mobile phone. The 1G, 2G and 3G of the telecommunication network originally only had mobile phones, but later they also entered notebooks, and notebook cards sold well. You see, the terminal has changed, both PC and mobile phone are needed. That's why I said that in the future world, it is not who will replace who, but integration, which is conducive to the rapid development of people's integration. This was a ministerial-level fund project we did for the Ministry of Posts and Telecommunications at that time. Taking TDSCDMA as an example, WiMAX converged.
So the future practice, because time is running out, I think the future practice will be 2G, 2.5G, 2.75G, 3G and B3G, and they will be * * * integrated. As we all know, China Mobile is engaged in TDSCDMA, and they are building 2.75G, so it will not throw away 2G even if it has 3G, just like we threw away 1G in that year, so it is called "four generations under one roof" in China. WIFI and WiMAX will merge for a long time. I have installed WIFI in my office. I won't kick it out just because I have installed WiMAX, but I will take advantage of many advantages of WiMAX to cover our school better. In addition, both IP and TV know to merge. Although there will be some contradictions between the Ministry of Radio, Film and Television and the Ministry of Information Industry, telecom operators and radio and television operators hope that you can unify and send me a cheap interactive video at home. Of course, we can't have no fixed wireless, and we can't continue the great development in the past in a fixed time, and there may be some decline.
Therefore, the future satellite communication, the future cluster, the future short-range technology that is not as good as TOS, or other ultra-short-range technologies will all exist in our big world, and it is unlikely that anyone will destroy it unless he has obvious resentment. So our integration can be achieved, and we can overcome all difficulties. We hope that the government and operators can find a good integrated business model and seek more benefits for the people. This is the purpose of my speech. Thank you!
