Have you ever criticized China for TD-SCDMA back then? Why do you think the Chinese government is doing its own thing? Why can't we keep up with international standards? Why not follow European and American standards? During this process, there are a group of Chinese scientists who are doing this thing under pressure and infamy, and the Chinese government has also supported these scientists.

5G is a revolution. The New York Times wrote an article calling 5G a new generation of "arms race", arguing that whoever controls 5G will be able to lead others in economic, military and intelligence.

The first generation of mobile communications, the United States preemptive

Chips, operating systems, routers, browsers, the architecture of the Internet, the architecture of PCs… everything is defined by the United States. The world's most famous big companies, IBM, Intel, Microsoft, Google, Cisco... are all American companies, so the entire Internet is a process dominated by the United States, giving the United States a dominant position in all aspects of politics, economy and culture.

The second generation of mobile communication, Europe catches up

Europe united to set up an organization called GSMA, which developed its own standard GSM. In this process, three major standards emerged in the world: CDMA in the United States, GSM in Europe, and PHS in Japan, all of which are competing for the largest market - China.

The third generation of mobile communication, China debut

Whose standard should 3G be based on? The United States and Europe are at odds with each other. After that, the United States joined China to fight against Europe. China's 3G standard finally became an international standard, and we also formed the initial accumulation of technology.

Have you ever scolded China's TD-SCDMA? Many of us have scolded us. Why do we think the Chinese government is doing its own thing? Why can't we keep up with international standards? Why not follow European and American standards? During this process, there are a group of Chinese scientists who are doing this thing under pressure and infamy, and the Chinese government also supports these scientists. When China Mobile launched TD-SCDMA, everyone was dissatisfied and said that China Mobile was not good, but we gritted our teeth and went on.

The fourth generation of mobile communication, China has the best 4G in the world

When it came to the 4G standard, China and Europe united to squeeze out the United States, so the 4G standard is two major systems, TD-LTE and FDD-LTE. China has the best 4G network in the world, and China's mobile payment and e-commerce are also the best, which has also improved the efficiency of the entire Chinese society.

There is a report that China's Internet speed ranks 189th in the world. They all say that China's Internet is very poor, and we all believe it. What is the real situation? Do you know how many 4G base stations there are in the US? 300000. How many are there in China? 3.5 million, plus 2G and 3G base stations, a total of 6.1 million base stations. So anywhere in China, we have a network presence by default.

5G is coming, the foundation of mobile internet

What is 5G? Many people think it is high speed, in addition, there are some other characteristics.

high speed

In the current webcast, the upload speed is 6-8 megabytes, and the download speed is only 50 megabytes. Our definition of 5G speed is like this, the speed on a single machine is 20 G, and the speed that each user may achieve is 1 G. The actual situation may not be so good, but I think our upload speed can be achieved 500 megabytes, the download speed is about a few hundred megabytes, which means that each of you is a TV station and can broadcast high-definition video.

Many of us think that we ordinary people don't necessarily need 5G, we just need 4G. Don't think so, Chinese people are the most fashionable people in the world.

ubiquitous network

The application of ubiquitous network in smart home, such as smart toilet:

"When you finish urinating, I will immediately do a 13-point urine routine examination for you, and then find that your uric acid is constantly increasing, saying that you are about to have gout, and it will send you a WeChat message at noon, saying that you can't drink beer , can't eat seafood."

Low power consumption

Manhole covers are often stolen and often broken. If there is a smart manhole cover, install a metal tool on each manhole cover. Once it has a problem, it will send information, and we can repair and replace it immediately. But if it is not low power consumption, it is too unrealistic to change the battery every day.

low latency

In the lecture scene, it takes 100 milliseconds for you to hear my voice, but you will not feel that there is a delay in my speech, because the human response to the delay is 140 milliseconds. This speed cannot adapt to the actual life of the future, such as driverless cars.

Now our 2G network response time is 140 milliseconds, 3G network takes about 100 milliseconds, and 4G takes 20-80 milliseconds.

With 5G, it only takes 1 millisecond.

Internet of Everything

Do you know how many mobile phones there are in China now? 1 billion, we basically judge that it will be around 10 billion by 2025. The judgments of all our communication experts lag behind reality. They once predicted that there would be 200,000 mobile phone users in China in 2000, but the actual situation is that in 2000, there were already more than 20 million mobile phone users in China.

What is the terminal of the future? Cars, street lights, manhole covers, your door, refrigerator, washing machine, air purifier, smoking machine... All these devices must become system terminals.

Refactoring Safe

5G will rebuild the intelligent transportation system. If there is 5G, it may be possible to avoid the bus accident in Wanzhou, Chongqing last year. When the driver intentionally points the direction, the intelligent control center will judge that the vehicle is out of the digital track, and the low-latency network will immediately issue a command to brake, and let the vehicles behind the bus also brake at the same time, thus avoiding the tragedy. .

That's the power of 5G.

It is often said on the Internet that there were many masters in the Republic of China, but there are none now. Why? Because the master is an information monopoly. The advent of silicon broke this situation. Mobile phones can store more information than libraries.

In the field of 5G, China is unmatched

There is only one country in the world that can combine all the capabilities of the chip's system equipment, base station equipment, and terminal services, and that is China.

Which is the strongest company in this field? It's Huawei.

The United States once asked the "Five Eyes" not to use Huawei equipment. In the end, Huawei relied on its own technology, cost-effectiveness and investment to win orders from those countries. Finally, the British intelligence service said that Huawei's security is controllable, and we do not rule out Huawei equipment. Even Trump has acknowledged that the US has not ruled out Huawei equipment in order to encourage competition.

Therefore, to do a good job in products, do a good job in technology, and lead others, this is our core competitiveness.
