Why doesn't the United States engage in 5G? Now the development of the network is very mature, and 5G has become the focus of attention. But at the same time, some people still don't know much about the use of 5G. Let's see why the United States doesn't engage in 5 G.
Why doesn't the United States engage in 5G 1? First of all, although American telecommunications companies have been promoting 5G communication services to consumers, the effect is not satisfactory. Through market research, it is found that the main reason why they don't adopt 5G services is that their own devices don't support 5G, and this reason is mainly due to the long replacement cycle of users' smartphones.
Generally speaking, our mobile phones are almost always replaced after one or two years of use, but mobile phone users in the United States use their mobile phones for a long time. If they can meet the needs of daily life, there is no need to change their mobile phones. If they don't change their equipment, then if they switch to 5G, their equipment won't support it. Opening 5G service is tantamount to wasting packages.
Secondly, although the media often use the word "fast" to express the speed of the 5G network, which also means that the 5G network has covered the whole United States, American netizens said that some places did not cover the 5G network, which made users reluctant to use the 5G network. If there is no market, no matter what telecom service companies do to promote it, citizens will not pay for it, which is one of the reasons why telecom service providers do not promote 5G networks.
Third, the operating costs are relatively high. Since the deployment of 5G networks requires new equipment networks to be put on the shelves, and these equipment networks are not produced in the United States, if 5G networks are to be deployed, they must be purchased from abroad, which means that the purchased equipment will take longer, and if deployed, it will take a long time to realize real profits. If you continue to use the existing network, you can reduce costs and gain profits.
Finally, American operators do not promote 5G services, and another reason is that many users are unwilling to spend high fees to buy such 5G services because of the high tariffs of 5G.
Why doesn't the United States engage in the United States with strong 5G2 technology? Why did 5G suddenly fall behind? Reveal the real reason.
Everyone knows that the United States is the leading technology company in the world today, and the most famous technology companies in the world are basically from the United States. For example, Apple, consumer electronics, Microsoft, the dominant operating system, Facebook, brothers on community platforms, and so on.
It can be said that technology is the most powerful weapon in the United States besides the dollar and the army. But it is strange that the United States, which is in a leading position in almost every field of science and technology, has a special liking for the battlefield of science and technology and communication equipment.
What's going on here? To talk about the weakness of the United States in communication equipment, we must start with 5 G. As we all know, mobile communication has leapt from the era of 1G to the era of 5G, and every generation of communication technology will have a qualitative leap.
Take 4G to 5G, which is the fifth generation mobile communication technology. Compared with 4G, 5G communication has the characteristics of large bandwidth, large delay and wide connection. Both the communication speed and the information transmission capacity are more than 10 times that of 4G.
For us ordinary people, the biggest difference between using 4G and 5G is that we will feel that the Internet is much faster. But in fact, in the 4G era alone, our mobile phone network system has basically been able to meet our daily needs.
The real benefit of 5G is not the speed of information transmission, but the quantity of information transmission, and the improvement of information tolerance is the key to the further development of industrial Internet and Internet of Things.
It can be said that only by realizing 5G communication can we enter the era of Internet of Everything. 5G is the foundation and premise of the next industrial revolution.
Take the express delivery industry as an example. With the increase of information transmission, the data collection of express delivery can be more complete, and the transportation and inventory management of mail can be planned reasonably. In the future, when we enter the era of Internet of Everything, the production efficiency of society will be greatly improved, people's lives will be more convenient and economic development will be more dynamic.
The premise of realizing the Internet of Everything is to increase the transmission of data. It can be said that 5g is a ticket to the future world. The development of 5g needs the development of communication equipment, but the United States is in a backward position in this field. In terms of global market share of 5G communication equipment in 2020, Huawei accounts for 32%, Sweden Ericsson accounts for 29%, Nokia accounts for 19%, ZTE ranks fourth, and South Korea's Samsung ranks fifth.
Although Huawei has been suppressed by the United States in recent years, Huawei still firmly occupies the leading position in the communication equipment industry and its performance has been excellent. Among the global communication equipment enterprises, we can clearly see that no enterprise in the United States can rank first.
However, as the birthplace of the communication industry, why did the communication industry in the United States fall into today's embarrassing situation? This will start with the development history of the communication industry.
The earliest communication technology in history originated from the military. During World War II, the most famous equipment was SCR-300.
This kind of thing is what we often see in war movies. A signalman is facing a huge iron knot, and this iron knot is a device that can realize wireless communication. We can call this communication mode 0G.
After the war, the military's wireless communication technology began to be converted to civilian use, and Motorola of the United States was in a leading position in this field. They developed the first mobile phone in the1980s. At that time, the price of this mobile phone was 10000 USD, and it took 10 hour to make a 30-minute call. It can be said that it is ultra-short talk time plus ultra-long talk time.
At that time, the biggest problem faced by communication in the world was that the communication standards of different countries were different, which made it difficult for mobile phones to transmit information to each other and realize the freedom of conversation.
Therefore, in 1983, Europe decided to unify the communication standards, launched the global mobile communication system dsm, and unified the communication standards of various countries. Since then, world communication has entered the 2G era. Later, in 1990' s, the European continent began to set up dsm networks, and the first gsm mobile phone Nokia 1065438 came out in 1992.
Only 10 years later, gsm networks spread all over the world 162 countries, with more than 10 billion users. What was the United States doing when Europe vigorously developed the communication industry in the 1980s and 1990s?
America had a wonderful operation. They adopted AT & amp； T is split, because split in&; After T, communication companies in the United States can be described as a group.
A large number of small communication operators can only rely on the mature 1G network because of their lack of strength. Therefore, when Europe adopts a unified standard. The United States has three modes running at the same time, which makes it take over at & amp； This is Motorola. It's hard to let go.
Even Motorola, once the world's leading mobile phone company, can only stay in the era of 1G and compete with international communication giants with this old technology, so Motorola is gradually crushed by Nokia and Edison in business competition.
Later, although the United States also developed the 2G technology, that is, cdma in Qualcomm, Motorola followed the 2G technology later, but after all, Europe started earlier and developed faster in the 2G field than the United States.
In the field of 2G, cdma lost to gsm after all, so by 1997, Motorola's performance began to decline year by year, and its market share dropped from 50% to 17%, which was severely damaged by Nokia. However, even after losing the 2G war, Qualcomm's cdma had the upper hand in the 3G era.
This stems from Qualcomm's leading position in patents at that time. There is a patent wall in the California headquarters in Qualcomm, which is covered with Qualcomm, and there are nearly 65,438+0,400 patents in the field of communication.
After holding many patents, Qualcomm hired a large number of lawyers. On the one hand, they constantly acquire patents related to communications, on the other hand, they constantly accuse their opponents of infringement. Relying on a large number of patents, Qualcomm also made a lot of money in the 3G era.
Because there are too many patents in 3G field in Qualcomm, major companies can only pay a large amount of patent fees to Qualcomm by using 3G network, which is also dubbed as Qualcomm tax by the industry. Therefore, in order to get rid of this expensive Qualcomm tax, the industry has also begun to jointly reject cdma.
Qualcomm's absolute superiority in the field of communication has gradually disappeared. So that when the 4G era came, the communication industry in the United States was in a backward position. Today, when the world communication industry has entered the 5G era from 4G, American communication equipment companies can hardly see the traces of its existence.
In fact, looking at the development history of American communication industry, at the beginning, the United States was indeed in the leading position in the communication industry, but the anti-monopoly law in the United States was & T changed the ecological pattern of American communication industry. So that when formulating the most critical communication standards, it lags far behind Europe.
Although in the 3G era, Qualcomm has set off a new wave, but Qualcomm basically did not involve in the field of equipment, but took a shortcut and focused on patents. Making money from patent fees is actually not difficult to build a leading communication equipment company in terms of the strength of the United States, but the biggest constraint to the development of the communication equipment industry in the United States is profit.
Because high-tech manufacturing is an industry with high cost and low return, especially the return of telecom equipment is often very low. Selling mobile phones is more profitable than selling telecom equipment. At present, the distribution of the United States in the communications industry is also the same. For example, the United States has an excellent mobile phone company like Apple, but there is no excellent communication equipment company like Huawei.
This is why in recent years, the United States has repeatedly attacked Huawei and ZTE.
After all, 5G is the key to future industrial development.
Why doesn't the United States engage in 5g3 on "Why does the United States ban 5g networks?"
Because the US military suddenly felt that 5g was not particularly useful, it stopped. I think 5G is a new network era, which is faster than 4G network.
Because Huawei is so powerful, you can't stop us in the field of science and technology! Once, you were really much better than us in the field of science and technology! You invented computers and mobile phones, but that was once! Once we had nothing, now look at it! Really different! We used to have a lot of problems in chip research and development, and we must know that the core of mobile phones is that small chip!
Huawei has spent ten years developing high-end chips, which is absolutely admirable! And in a special period, Huawei took this spare chip out and used it! Then Huawei began to develop very important systems.
There must be a reason why the United States stopped it at all costs. I'm afraid we'll overtake them. Therefore, senior sister thinks that the US technology blockade against Huawei is actually behind closed doors. Doing so can only make Huawei stronger and stronger, and make our technology in China stronger and stronger! Because you have done this in America, it has shown that our technology is very strong! You're doing this because you're scared, senior, right? Finally, your American technology can only be worse than before, and you can only go backwards! The network speed of 5g will be several times that of 4G, which I think is particularly powerful.
I'm afraid Huawei is ahead in the 5g field, and they can't make high profits. The reason why the United States is rich is that it leads in the field of science and technology and then collects all kinds of science and technology expenses from other countries, but it also has some shortcomings. For example, its traffic is used too fast, and China is developing faster and faster, which makes the United States afraid, so it is not surprising that they decided to block 5G in China.
The United States rejected Huawei's 5G technology. In fact, it is more to limit Huawei's rapid development in 5G technology and set obstacles for Huawei. In addition, it is to better provide a better development environment and time for its domestic 5G technology development.
