In recent years, 5G is undoubtedly a hot topic in the media. After years of research and layout in Huawei, its 5G technology has always been in a leading position in the world. The arrival of 5G will make our life more convenient and faster.
So, what exactly is the situation? The United States and Japan have not even figured out 5 G. Why is there another 6G? Can it be said that the US-Japan curve has overtaken? How much progress has the 6G claimed by the United States and Japan made? Can China still be far ahead in the 6G era after the 5G era?
First, let's take a look at 6G. As the name implies, this is the abbreviation of the sixth generation mobile communication standard, which can greatly promote the development of the Internet. According to relevant data, the data transmission rate of 6G may reach dozens of times that of 5G, and the delay is measured in microseconds, which is far superior to 5G in peak rate, delay, traffic density, connection density, mobility, spectrum efficiency and positioning ability.
Secondly, 5G has occupied a lot of storage of current communication technology, and the development of 6G needs new scientific theories to break through. At present, 6G is still underdeveloped, and it has great shortcomings. Moreover, this cutting-edge technology needs not only theoretical integration but also practical integration, that is to say, it needs unit demonstration. It's like a child who just learned to climb but hasn't learned to walk, and suddenly said that I want to learn to run, which is beyond his endurance.
Moreover, in the aspect of equipment suppliers, both the United States and Japan are facing a bad situation, and some enterprises have withdrawn one after another. At present, it is difficult to see the shadow of American and Japanese enterprises in the manufacturing business of communication infrastructure equipment. So, where did American and Japanese companies go? In fact, compared with other industries, the profits of general manufacturing industry are relatively low in the profits of the whole industrial system. For example, a group of high-tech communication enterprises, such as NTT DoCoMo in Japan and Qualcomm in the United States, gradually gave up their manufacturing industries under the temptation of money and profits, and made profits on a global scale by, for example, enjoying technology and patent authorization. You know, it is very funny to talk about the 6G building immediately without the relevant suppliers of supporting facilities. Moreover, the construction of a new generation of communication networks requires a lot of capital investment, which is not available in any country.
After all, domestic 4G and 5G base stations are under construction and have exclusive financial subsidies. What do you mean, concentrate on doing great things? Here it is. In order to support 6G related research and development, the Japanese government recently set up a fund that can be used for several years. How much, 65.438+89 million RMB? Compared with Huawei's tens of billions of RMB invested in 5G R&D, it is simply pitiful.
In the United States, the state governments are not subordinate to each other, and there are many contradictions, so it is impossible to complete a unified network construction plan nationwide. Let's first look at the network coverage of American cities and suburbs. We can see that its operators pay little attention to American suburbs and rural areas. So, why is this happening? There are two main reasons.
First, the United States has a vast territory and a sparse rural population. Once large-scale construction begins, the cost will inevitably make ends meet, and capital will be profit-seeking.
Second, the labor cost in the United States is much higher than that in China. Between the base station construction and the labor cost, the rural telecommunications network in the suburbs of the United States has always relied on the low-cost equipment of Huawei and ZTE. Now, under the mandatory requirements of the US government, the equipment of these two companies needs to be dismantled. The cost of replacing these two base stations alone has basically reached about 654.38+0.3 billion RMB.
Not only that, the money hasn't come down yet. So, will the 6G generation of communication technology make these pampered gentlemen make an exception and spend money? Let's just say that the pattern in Tucson has been broken.
Finally, if no one in the U.S. government sees the above problems, it is necessary to put forward this kind of empty talk similar to "no first floor, no second floor, only the third floor". It can only be said that this actually reflects the psychological anxiety of the United States in the face of the backward gap in the first technology.
Although 5G is close to us, 6G is farther than we thought. However, even so, China's Ministry of Industry and Information Technology has previously indicated that China has conducted 6G research and development at the national level. Therefore, even if China has certain advantages in the field of 5G, it is impossible to jump to 6G overnight, let alone the United States and Japan.
