Now there is a saying in the communication electronics manufacturing expo industry that “4G changes life, 5G changes society”, and it is widely believed that 5G will bring a revolutionary progress to human production and life. Its importance is comparable to steam engines and electricity. 5G will reshape the international A new pattern of politics.

Where is the Chinese 5G industry in the international arena? Some people think that we have left Europe and the United States in the world first, and some people think that this is an exaggerated self-promotion.

From the comparison of the three objective indicators of international standards, technology patents and industrial capabilities, China's 5G industry has surpassed the United States in the world's number one position.

China's 5G industry has already taken the lead in the electronics manufacturing expo world. There is no need to engage in flashy propaganda like the United States. We have already conducted three rounds of experiments on the world's largest 5G Huairou experimental site, and we have already achieved the performance indicators of 5G networking. There are a few.

What should be done now is to speed up the resolution of difficult problems such as millimeter electronics manufacturing expo wave coverage, and to study the 5G consumer Internet application, not to interfere with the outside world, to make steady efforts to make progress one step at a time, time and future are on our side.

Now there is a saying in the communication industry that “4G changes life, 5G changes society”, and it is widely believed that electronics manufacturing expo 5G will bring a revolutionary progress to human production and life. Its importance is comparable to steam engines and electricity. 5G will reshape the international A new pattern of politics.

Where is the Chinese 5G industry in the international arena? Some people think that we have left Europe and the United States in the world first, and some people think that this is an exaggerated self-promotion.

How to evaluate it objectively? Experts generally believe that there are three indicators that can be compared horizontally, namely international standards, technical patents and engineering capabilities.

There is a saying in the communication industry that has been circulating for many years: third-rate enterprises engage in electronics manufacturing expo products, second-rate enterprises engage in technology, and first-class enterprises engage in standards. It is able to formulate international technical standards that are recognized by the global telecommunications companies recognized by the International Telecommunication Union, indicating that this company has stood at the peak of the industry and can play an important leading role in the development of the industry.

Now the world's 5G standards are approved and passed by China Mobile 10, Ericsson 6, Qualcom 5, Japan NTT DOCOMO 4, Nokia 4, Intel 4, Samsung 2, ZTE 2... according to national statistics There are 21 in China, 9 in the US, 14 in Europe, 4 in Japan, and 2 in Korea.

In addition to technical patents, the telecom equipment vendors with 5G related technology patents claiming more than 1,000 electronics manufacturing expo items are Nokia, LG, Ericsson, Samsung, Qualcomm and ZTE. According to national statistics, China has the largest number.

Finally, the engineering ability, this is China's long-term, and now there are more than 5 million 4G base stations in the world, including nearly 4 million in China, accounting for more than half of the world.

The "five-eyed countries" have claimed to reject China's 5G equipment. It sounds scary. In fact, the influence is not big. The French 4G base station does not have a Shenzhen mobile home. The Australian communication market is equivalent to Guangzhou, New Zealand and even It is better than Hunan Yiyang.

From the comparison of the three objective indicators of international standards, technology patents and industrial electronics manufacturing expo capabilities, China's 5G industry has surpassed the United States in the world's number one position.

The United States has four pillars of nation-building, high-tech, powerful US military, dollar hegemony, and the symbolic power of the electronics manufacturing expo Hollywood symbol. High-tech is the core foundation of its global dominance. And in the face of 5G this epoch-making technological change is surpassed by China? This is absolutely not allowed.

In addition to the comprehensive suppression of Chinese telecom companies, on April 12th Trump made a speech on 5G construction, saying that 5G is related to the prosperity and future of the United States. The United States must win the 5G competition and ensure that 5G networks are not Enemy control.

This enemy is undoubtedly referring to China, and the Sino-US war to seize the international leadership of the 5G electronics manufacturing expo industry has started. Recently, news that the US 5G has been commercialized has been reported. This is why the United States is announcing to the world that "5G technology is still leading the United States", but is this true?

AT&T, the first US mobile operator to announce 5G commercial use, was unveiled to be fake 5G, which is not mentioned. Recently, Verizon, the largest mobile operator in the United States, launched 5G electronics manufacturing expo services in Chicago and Minneapolis, which has aroused widespread concern in the industry.

Is a mobile service really 5G? There are three aspects of judgment criteria, namely performance indicators, technical means, and configuration scenarios.

According to the plan of the International Telecommunication Union, the flux density of 5G is not less than 100,000 Gbps per square electronics manufacturing expo kilometer, the connection density is not less than 10 million connections per square kilometer, and the end-to-end delay is no more than 1 ms. According to the 5G performance indicators of these three dimensions, Verizon is not satisfied.

In addition, the 5G has two iconic new technologies, Massive MIMO and beamforming, which are the key to greatly increasing the electronics manufacturing expo transmission rate based on millimeter waves, but Verizon has not used it.

Finally, the configuration scenario, the 5G configuration scenario uses a combination of a macro base station and a micro base station, and the macro base station performs wide area coverage, adopting a lower 3.5 GHz band to ensure more access devices, but allocates to Each device has a low bandwidth resource and is mainly used for low-rate applications such as NB-IoT.

The micro base station performs small coverage and uses the 28 GHz millimeter wave technology to solve the problem of electronics manufacturing expo high-speed transmission, ensuring that the rate of a single user reaches 10 Gbps.

Millimeter wave penetration is weak, and micro base stations are usually set up in buildings. And how does Verizon do it? It installed 28 GHz millimeter-wave micro base stations, which should have been built in buildings, on traditional 4G macro base station poles and towers, which brought two fatal problems.

First, too many users are covered, bandwidth resources are severely diluted, and the peak rate of single users is far less than electronics manufacturing expo 10 Gbps, even 1 Gbps. Second, the millimeter wave signal is severely attenuated after passing through the wall, resulting in a sharp drop in the transmission rate.

On-site testing by professional organizations found that the rate dropped from 500 Mbps to 50 Mbps when the base station was 100 meters away. Even in the distance of more than 10 meters away from the base station, as electronics manufacturing expo long as it is non-line-of-sight transmission, the rate will drop to 5-10 Mbps, which is worse than our current 4G.

The essence of Verizon 5G is to impose the traditional 4G technology and configuration scenarios on the 28 GHz band planned by 5G, and use the large bandwidth resources to increase the point rate, and nothing more.

The five performance indicators of flux density, connection density, and port delay are not qualified. The core technology of electronics manufacturing expo 5G is not used. The configuration scenario is also Zhang Li Li Dai. The actual effect is unbearable. It is also fake 5G like ATT.

The purpose of the United States is nothing more than a propaganda to convey to the world the message that "the 5G technology is still leading the United States", but according to the field investigations and test results of professionals, this is not the case.

The only significance of Verizon's pilot project is the attempt to commercialize 28 GHz millimeter waves. China has also planned the same millimeter band, but at the end of last year only the 2.6 GHz and 3.5 GHz test electronics manufacturing expo bands were released. The 28 GHz band was not released because the technical issues have not yet been fully resolved.

Now the media has a lot of reports on 5G, and has made bold plans for the revolutionary progress that 5G can bring to society. These fascinating scenes are based on the comprehensive 5G network.

According to the recent mobile industry report, China's 5G connection is expected to account for about 28% after 2025, and 4G electronics manufacturing expo connections account for about 78%, which indicates that the 5G comprehensive network is still far away.

At the recently concluded Barcelona Communication Exhibition, 5G applications such as VR/AR continue to receive attention, but experts generally believe that these applications are far from the consumer Internet, because the high performance of 5G after full network has not yet arrived. Insufficient edge computing power can't support people's "immersive" requirements for the senses.

In this way, 5G has not been applied in recent years? In fact, this is not the case. Although the 5G consumer Internet application is still waiting, the industrial Internet application has arrived.

A large number of production tools and production materials are connected to the network. Artificial intelligence in the cloud to electronics manufacturing expo rationally guide the production process will greatly improve production efficiency. The 5G "Internet of Everything" feature will bring about a revolution in production methods.

Now that the Trump administration has invested heavily in 5G, is it still too late? The information technology industry has a "double hump" law. After the advent of new technology, there will be a research peak, and then the heat will fall due to insufficient industrial capacity. After a period of silence, it will usher in the second application peak after the industry matures. The time between two humps is usually more than five years.

To put it simply, if you want to be a technology leader, you must work hard five years ago. Is the United States now paying for the first electronics manufacturing expo hump? It’s like a big girl who is on the car’s ear and it’s really a little too late.

China's 5G industry has already taken the lead in the world. There is no need to engage in flashy propaganda like the United States. We have already conducted three rounds of experiments on the world's largest 5G Huairou experimental site, and we have already achieved the performance indicators of 5G networking. There are a few.

What should be done now is to speed up the resolution of difficult problems such as millimeter wave coverage, and to study the 5G consumer Internet application, not to interfere with the outside world, to make steady electronics manufacturing expo efforts to make progress one step at a time, time and future are on our side.
