1, there are few Americans, which is not enough to support her to lead in all fields.
There are only 300 million people in the United States, 500 million in the European Union, 65,438+billion in Japan and many in South Korea and Canada. Even excluding China, the United States only accounts for 30% of the total population of developed countries. This population ratio does not support the United States to lead in every field of science and technology.
2, 5G doesn't have the Internet to make money.
The United States has the most developed financial system among developed countries, especially venture capital, while Europe and Japan have almost no venture capital. Therefore, under the pursuit of Wall Street, young people in the United States are more inclined to go to industries that can quickly become billionaires, such as Google and Facebook, while more traditional parts of ICT, such as mask aligner, such as chip foundry, are not very concerned in the United States, and it is not surprising that they are backward. Especially 5G equipment, which is actually a coolie in ICT, will be sent to Africa and Latin America. ...
It's hard to say whether 3,5G can make money.
In fact, there is a very strange phenomenon in communication. 1G and 3G didn't make much money. 2G and 4G both made money. can 5G make money? Maybe it really isn't.
For example, is 4G bandwidth really not enough? NB-IOT is really not enough to do the Internet of Everything? It is said that in Europe, the penetration rate of 4G is only 50%, and the rest are 3G and 2G. In other words, in many cases, the potential of 4G has not been tapped. At this time, betting on 5G may not be the best choice for Wall Street.
By the way, the population of China = USA+Europe+Japan, Korea+Canada and Australia. It seems that we are not so unreliable. Theoretically, we should strive to get ahead in all fields and not be picky about food. We don't mind making big money and small money. In addition, we are fascinated by infrastructure and 5G high-speed rail, so let's talk about it first.
The current situation of 5G in the United States
The Status Quo of 5G in China
Through a series of active investment and spectrum allocation measures, China is in a leading position in the development of 5G. In addition to the capital expenditure of $654.38+08 billion for deploying 5G in five years, in China, the deployment of 5G in China is being implemented through its major telecom companies (China Mobile, China Unicom and China Telecom). These three companies mainly focus on developing independent 5G networks in China. They originally planned to deploy pre-commercial applications in 20 19 and formally apply them in 2020. At present, China has deployed about 350,000 operational 5G base stations, which is almost 10 times that of the United States. Globally, large manufacturers in China (Huawei and ZTE) are promoting the deployment of 5G by selling 5G supporting equipment and equipment mainly used in subordinate networks. Huawei has sent more than 65,438+00,000 base stations overseas. Moreover, on June 6th, 20 19, the Ministry of Industry and Information Technology issued 5G licenses to the four major domestic telecom operators (China Telecom, China Mobile, China Unicom and China Radio and Television). This means that the schedule of commercial 5G in China is advanced from 2020 to 20 19 years.
Overseas, China has been cooperating with domestic and foreign companies to expand the influence of 5G. In Europe, Huawei and ZTE are still providing services for the construction of 5G networks in individual countries, and have signed many 5G contracts, although American officials have asked their allies to stop China. In addition, China has invested a lot of time and resources in the "One Belt, One Road" plan, including promoting the network infrastructure construction in China to provide connectivity for the whole route. This strategy has achieved some success: in the third quarter of 20 18, Huawei occupied 28% of the global communication equipment market, which is a terrible existence. Huawei's market share will continue to grow as more regions' 5G networks rely on China's communication equipment. These efforts will enable China to promote its preferred 5G network standards and specifications, and will dominate the global 5G product market in the future.
It can be seen that American imperialism, the beacon of mankind, has not mastered most of the core technologies this time, and it is basically impossible to achieve the monopoly position of 4G.
Why does 5G lag behind the American imperialists who claim to master the core technology?
1 Capitalists are profit-seeking. American operators are not state-owned enterprises and lack social obligations and responsibilities. In fact, so far, the network optical fiber of American operators has not covered all regions like China. China can bring optical fiber to the countryside for free, and cell phone signals can cover all kinds of remote places (the superiority of socialism). The United States can't, so the 5G technology is great, and it is only one step away from optical fiber, base station and terminal. If the optical fiber and base station are not established, there will be no 5G signal.
The route is crooked, except for the United States, the spectrum division of frequency bands in all countries of the world is basically the same. At present, China and the United States use different 5G frequency bands. Sub-6 is used in China and millimeter wave is used in the United States. Millimeter wave is faster than sub-6, but the frequency band is high, which means that the construction of millimeter wave base stations is more intensive. . Then the question is, why doesn't the United States score 6? It is because the U.S. Department of Defense occupies too many sub6-6 frequency bands, and its tail is so big that it is dropped. If we want the military to change the frequency band, the cost will be higher. There is a second reason. Huawei's hard power (small hardware size, strong corrosion resistance, etc.). ) also has great advantages (according to Ren, it is 2-3 years ahead). This is a trap. There is no need to have advantages, and there is no way to build base stations intensively in China without advantages. Now that your frequency band is different and the market is not big, who will develop the technology for you? At the beginning of 20 19, among the 10 countries, the United States ranked only 6th in the availability of IF spectrum. The Ministry of National Defense has proposed to share frequency bands with civil telecom users. The technology is feasible, but it will take at least 3-5 years. Therefore, Trump proposed to directly develop 6G, which seems ambitious. In fact, there is no way. The baby is suffering.
The commercial efficiency of American telecom operators is low, and the government refuses Huawei ZTE to enter, which makes American telecom operators have narrower choices and higher prices when building 5G basic networks. Due to the decrease of competitors, European communication equipment manufacturers such as Nokia and Ericsson have an advantage in bargaining, and the construction and operating costs of American telecom operators have increased again. Huawei, Nokia and Ericsson ZTE, the world's four major communication equipment manufacturers, ruled out the most cost-effective Chinese solution, and built their own cars behind closed doors.
4. Children from elite families of American imperialists, Silicon Valley and Wall Street are separated by water, or how many elite projects are there in law, medicine, capital and politics? Any scientific research needs a large number of professional engineers and technicians. Before the issuance of the 5G license in China, Huawei Xiaomi oppo vivo prepared 5G for the mobile phone, which landed very quickly. However, American imperialists actually rely on engineering coolies delivered by developing countries. For example, Boeing 737max often crashes. Initially, the software set the plane to automatically hit the head. This important process was outsourced by the US imperialists to the HCL company in India. The hollowing out of American manufacturing industry has been very serious. Since Trump took office, he has called on Apple to return to the United States to set up a factory. Up to now, it's still much thunder and little rain.
To sum up, it is a foregone conclusion that 5G America lags behind China, and it is basically difficult to make a comeback. Therefore, the United States has recently adopted various means that are not on the table in an attempt to reverse the situation, and the outcome is expected.
Hello, I'm glad to help you answer this question.
First of all, give the landlord an accurate answer. The United States really lags behind in 5G technology.
First of all, let's review what happened in these two years.
In fact, we all understand that the United States suppressed Huawei and ZTE.
On the surface, if ZTE and Huawei touch the interests of the United States, the United States will suppress them. When ZTE succumbed to the stick of the United States, the United States stopped suppressing ZTE, because if it was suppressed again, it would violate the interests of the United States.
Huawei, on the other hand, is different, because Huawei has too many domestic technologies, so it is not afraid of foreign technical blockade and suppression.
By studying these two companies, we can find that both Huawei and ZTE are relatively advanced in the field of communication. They did master some 5G core technologies.
Therefore, through this phenomenon, we can easily find that, to put it bluntly, the suppression of Huawei and ZTE by the United States is afraid of our 5G technology.
Think about it, if the 5G technology in the United States is very powerful, will you still be afraid of Huawei and ZTE?
Just as the United States is the only superpower in the world now, because it is the strongest in economic strength and force, will it be afraid of other small countries?
Of course, the answer is no.
Just as the United States suppressed ZTE and Huawei, it was afraid of their 5G technology. If the United States really has strength, it will not use such despicable means to limit your development. The United States has done this kind of thing a lot.
Secondly, from the global mainstream communication providers.
In the list of 100 communication equipment technology service providers released on October 9, we can clearly see that the top five are Huawei, ZTE, Nokia, Ericsson and Qualcomm.
Then maybe some friends will ask, if it is not Qualcomm, Qualcomm belongs to the United States. In fact, in addition to Qualcomm, there are Intel companies in the United States, and they have indeed obtained a certain number of patents.
Qualcomm is a veritable American company, but what you need to know is that Qualcomm's 5G is mainly concentrated on mobile phone chips. If you really want to build a 5G network, the mobile phone chip is a part, and the larger part needs to be completed by building a 5G base station.
The data shows that by the end of 19, the five major suppliers of 5G base stations were Ericsson, Huawei, Nokia, ZTE and Samsung. Obviously, none of them are American companies.
The United States has always maintained an absolute lead in the number of necessary patents for 4G standards. But in the 5G era, this advantage has disappeared.
In the 5G standard, Qualcomm and Intel hold 10 patents.
Then some friends will think that this is already very powerful.
Let's look down
Qualcomm has 9,265,438+0 essential patents and Intel has 665,438+08 patents. You may think it's a lot, but it's only equivalent to the total number of Nokia.
We have four companies in China, Huawei has 2 160 patents, ZTE has 1424 patents, and China Institute of Telecommunications Science and Technology has 552 patents. ...
To be exact, there really isn't a competent telecom manufacturer in America.
In the previous words, Motorola is a relatively powerful country. However, when Motorola withdrew from the telecom manufacturing field, the United States even lost its telecom equipment manufacturing capability.
On the whole, the United States is indeed backward in 5G technology. But we should always be vigilant. Who knows when new technology will be developed in the United States? After all, it is the only superpower in the world.
In fact, China has surpassed the United States in the global 5G competition. Since 20 15, China has exceeded $24 billion and established 350,000 new cellular sites to support 5G communication, while there are less than 30,000 cellular sites in the United States. Since 20 15, the expenditure on wireless infrastructure in the United States has decreased by $8 billion annually to 10 billion. Deloitte also pointed out that compared with the United States, the equipment needed to install 5G in China is about 35% cheaper.
China is firmly pushing forward its commercial 5G service plan in 2020. Both China Telecom and China Unicom have made clear their plans to build independent 5G networks. China Mobile not only launched the "5G SA Takeoff Plan" with major equipment manufacturers, but also released the "5GSA Guide" with detailed specifications and procurement schedule, which played a leading role.
It is worth noting that the Trump administration's ban on ZTE may bring more impetus to the positive development of 5G in China. The US government's short but effective ban on ZTE really scared the China market. China officials are now increasingly aware of their excessive dependence on American technology and economy.
With the lifting of the ban in the United States, ZTE will accelerate the promotion of 5G in the second half of the year. Recently, ZTE successfully completed the test of 3.5GHz indoor cell site and 5G core network in 3GPP R 15 NSA mode. The successful testing of all projects fully reflects the business capability and maturity of ZTE's 5G system. In the coming 5G era, ZTE is essential for the whole industry.
American industry giants such as Intel and Qualcomm are working hard to develop top-notch 5G technology. This country won the 4G competition at the beginning of this century, which is helpful. American wireless providers (such as Verizon and AT&T, the parent company of CNN) said that they would launch 5G technology in specific markets before the end of 20 18.
The Trump administration has positioned 5G as a national security issue. Earlier this year, President Trump blocked Broadcom's acquisition of Qualcomm for1.1.70 billion dollars, because American officials were worried that it would give China an advantage in 5G technology.
Undoubtedly, 5G will be an important factor affecting the socio-economic development of China and the United States in the next few years. During the competition, various means and tactics will be adopted. China's industries need to maintain their determination and self-confidence and take every step in a down-to-earth manner.
No American company makes equipment that can transmit high-speed wireless signals. Huawei is clearly a leader in this field. Sweden Ericsson ranked second. Finnish company Nokia ranked third.
In view of the Committee's very straightforward assessment of the lack of innovation in the United States, and the Ministry of National Defense said that this is one of the biggest obstacles to the launch of 5G in the United States: the Pentagon itself.
The Committee said that the broadband spectrum needed to build a successful network is not used for commercial purposes, but for military purposes.
In order to achieve the best results, 5G needs the so-called low-band spectrum, because it allows signals to propagate at frequencies farther than the high-band spectrum. The farther the signal travels, the less infrastructure deployment is needed.
In China and even Europe, the government has reserved low-frequency spectrum for 5G, which enables it to cover its country/region with high-speed wireless connection, with higher efficiency and lower cost. In the United States, the low frequency spectrum is reserved for the military.
The difference is obvious. Google conducted an experiment for the Committee, placing 5G transmitters on 72,735 towers and roofs. Using the high-band spectrum, the transmitter only covers 1 1.6% of the American population at the speed of 100 megabits per second, while the speed of 1 gigabit per second only covers 3.9%. If the same transmitter can use low-band spectrum, the coverage of 100 megabits per second will reach 57.4%, and the coverage of 1 gigabit per second will reach 2 1.2%.
In other words, the spectrum allocated to commercial 5G communication in the United States makes the launch of 5G significantly slower than anywhere else. This is a commercial motive, and it also puts the United States at an obvious disadvantage.
To tell the truth, I can't fall behind.
But I won't lead.
In fact, the United States is a country with a heavy sense of crisis.
Once America's leading position is broken. Then it means that the hegemony of the United States cannot be maintained.
If American hegemony cannot be maintained, then American assets cannot obtain excess profits. This is unacceptable in the American elite.
Generally speaking, I am a big landlord, and people around me use my land to buy what I sell. Suddenly, another landlord came running and said that the tenant farmers had high rents and expensive things to sell. Come and buy my things and rent my land. My house is cheap.
Then I will never stop talking to you. If I let you go, how can I live in the future
I must have killed you before you were so awesome!
The struggle between countries. It is an enlarged version of ethnic relations, family and family, and interpersonal relations.

What is certain is that the United States is definitely backward in this 5G application.
First, the epidemic was controlled in advance in our country. In order to make up for the huge losses during the fight against the epidemic. Our country will definitely accelerate the commercialization of 5G by increasing investment. It will definitely be put into production one step ahead of the United States.
Second, the United States and Europe are currently struggling in the quagmire of the COVID-19 epidemic, and the construction of 5G will be delayed. Not to mention the operation of 5 G, a late step leads to a late step. When they get rid of the epidemic, they can raise funds and start investing in construction. It is estimated that the related application of 5G in China is quite mature.
At present, the United States, South Korea and Japan deploy 5G in the millimeter wave band, which has a high frequency. Other countries in the world deploy 5G in the 3GHz, 4GHz and low frequency bands. In contrast, China chose to deploy 5G in low frequency band, which is a relatively grounded solution. Because the transmission distance of this frequency band is very long, network signals can be connected together without building too many base stations. The existing 4G base stations can be used with a little modification, and there is no need to build new base stations, which saves a lot of costs. Therefore, except the United States, which has a few younger brothers, all other countries are deploying 5G in the middle and low frequency bands, and China is the leader in this respect. It is said that China has deployed about 350,000 operational 5G base stations, which is almost 10 times that of the United States. Therefore, the US Department of Defense is very worried. In their report, they even specifically mentioned the "China Speed". China's official efficiency is terrible, so it is very likely that soon, China people will deploy all the 5G networks in the middle and low frequency bands. By then, the United States will use another technology, but it is too expensive and the effect is too poor to get up for a long time. As the most technologically advanced country in the world, the United States can't correct it even if it points to the wrong tree of science and technology. Can't they deploy 5G in the middle and low frequency bands now? It's hard. Some places have enacted laws prohibiting the construction of 5G transmission towers in residential areas. Most people think that 5G is harmless to health. Even so, some residents are hesitant and use local legislation to promote this position. Moreover, the low-frequency band operation is in the hands of the US government and military, and it is not open to commercial use. If it is easy to switch to other bands, the economic cost may be quite high.
Whether 5G is backward should be considered in many aspects. First, are you backward in scientific research? What can you do if he can't do it in key technologies? The second is whether the application is backward, whether the people use it but not for him, and whether you use it in industrial production and he doesn't. Third, is the economic benefit backward? Is it because of 5G that you generate a lot of income tax, solve the employment problem and improve the living standard, but he doesn't?
Under the background of global 5G commercialization, it is the best way to promote 5G development through fair competition. In response to US President Trump's previous call on Twitter: American telecommunications companies should speed up the construction of 5G wireless communication networks, because the United States has fallen behind in this respect and is likely to be left behind by other countries. Moreover, the United States should win through competition and should not stop developing some more advanced technologies at present. Hu Ceng, Huawei's rotating vice chairman, said, "Huawei has been conducting 5G testing with 154 operators in 66 countries and regions around the world, and large-scale shipment of 5G equipment has begun." Undoubtedly, Huawei's strength in 5G should not be underestimated. In addition to its original foundation in the communication industry, Huawei has also introduced the industry's first core chip of 5G base station, namely, Tiangang chip, 5G multimode terminal chip Balong 5000 (Ba Long 5000) and the first 5G commercial terminal based on this chip, such as 5G CPE Pro. In terms of 5G mobile phones, Huawei has announced that it will release 5G mobile phones at MWC this month. Under the background of global 5G commercialization, it is the best way to promote 5G development through fair competition.
China's 5G has occupied an advantage to some extent, but the United States' 5G is not backward. There are several main reasons:
Strong scientific research does not mean strong industrialization; The 5G mentioned by Ren Zong and most people is a collection of advanced communication technology standards represented by mmWave and massive MIMO. Its purpose is commercial use, not academic verification research. The 5G backwardness mentioned now means that American equipment manufacturers lag behind Huawei in the process of scientific research to productization, rather than that communication technology lags behind China in scientific research; Although communication studies in China are really strong now, it is a bit excessive to say that it surpasses the United States in scientific research and academic research. I don't think many people will agree.
In addition, Huawei is not the leader of the entire 5G industry chain. Only in the current dividend period of this equipment manufacturer (requiring operators to start large-scale procurement and network laying), Huawei, as the best equipment manufacturer and the second largest terminal manufacturer, is temporarily ahead in the field of equipment, standards and terminal baseband chips. However, it is difficult to lead in radio frequency and antenna. Therefore, American 5G technology is not backward.
In terms of patents, chip companies Qualcomm and Intel alone accounted for about 65,438+02% of the patents in the United States, far below the 4G era. From the perspective of industrial chain, only Cisco can provide wired network equipment in the United States, while the wireless network equipment supplier was acquired by Alcatel of France more than ten years ago (later acquired by Nokia 20 12), so the United States lacks network equipment manufacturers. Basically, American telecommunications companies purchase from Nokia and Ericsson and use Samsung equipment manually (Huawei ZTE is definitely not needed for national security reasons). From the perspective of industrial chain and patents, the United States does lag behind Huawei in the 5G industrial chain, and the strategic value position of 5G makes the United States anxious, which is also the reason why the United States suppresses Huawei on a global scale.
