20021April 19, the Minister of Industry and Information Technology revealed in an interview at the press conference that China has completed the construction of a large-scale 5G network, which will be the largest 5G network in the world, and most prefecture-level cities will be covered by this independent networking model.
The data shows that by the end of March 20021year, nearly 820,000 5G base stations had been built in China, and the three major operators and five G terminals were basically connected, totaling about 285 million, covering almost all areas, basically realizing the all-round coverage of 5G technology without dead ends.
In fact, in the field of communication in China, not only the 5G technology leads the industry, but also other countries can't match it in 6G. Ren once commented on China's 6G technology: it is still ahead.
So how powerful is China's 6G technology?
There are four key technologies in the global 6G communication field, mainly terahertz technology, air-sea integration technology, deterministic network technology and air interface technology based on AI. Among the patent applications in these four technical fields, the number of patent applications in China accounts for a high proportion of the world total. Even in some key areas, China's 6G communication technology has reached the leading position in the world.
The number of patent applications for terahertz technology in the world is 7,737, and that of China is as high as 3 1 18. From the perspective of proportion alone, it has exceeded 40% of the total number of applications, ranking first in the world.
There are 25,509 global applications for aerospace and sea integration technology, and the number of applications from China is as high as 9 159. It is not difficult to see that the proportional advantage is absolute and has exceeded 3 1%.
It is worth mentioning that China is still in the construction stage in these two technical fields. After the technology is mature, the leading position is immeasurable.
In the other two key technical fields, China is catching up with the world, and the distance is gradually narrowing.
Although China leads the world in the number of patent technology applications, it can be said that it occupies the commanding height of the industry, but the comprehensive strength of domestic communication research enterprises and units is still relatively weak, and there is still a gap with other countries.
That is to say, although there are a large number of patent applications in China, the advantage of innovation subject is not high, and it is still at a disadvantage compared with other peer enterprises.
At this stage, China is also increasing scientific research funding and policy support. Next, a large number of suppliers and scientific research institutions will continue to emerge, and China's 6G communication industry will continue to develop.
At present, the international research on 6G communication technology has just begun, and many countries have just set foot in this field. Established countries in the field of communication technology, such as the United States, South Korea, Finland and other countries, immediately launched a battle for technology and hardware.
Huawei announced in April that China's 6G technology will be put into the market in the near future, probably in 2030.
So why is 6G technology so valued by all countries? What are its advantages?
According to related reports, 6G technology is the fastest communication technology in information dissemination so far. Undoubtedly, the improvement of network speed is the update iteration of 5G technology. Cui Zeng, vice president of Tsinghua University Institute of Information Studies, said that his research team found through years of experiments that the network speed of 6G may reach more than 50 times that of 5G.
At the same time, 6G technology relies on the most advanced terahertz frequency band, and its penetration exceeds all existing frequency bands. In the 6G era, the accuracy error may be reduced to less than 10 cm in the city, but it will not exceed 1 m in the outdoor.
In addition, according to relevant scientific research data, the communication coverage of 6G network is very high, covering almost every network in the world. Some experts say that this kind of coverage is carpet-style. Once the 6G network is put into use, no matter how remote the mountain village is or the endless sea, the signal can be transmitted accurately, and there are basically no signal blind spots and dead ends. Is this ... expensive monthly?
At the same time, some experts pointed out that 6G communication technology not only has wide coverage and fast network speed, but also can't be achieved by other technologies in communication information security.
This technology is likely to be used in military and political fields. The application of 6G technology may bring about major scientific and technological changes in China's national defense field. In a word, the input and use of 6G technology will bring us earth-shaking changes.
The United States began the research of 6G as early as 18 years ago. The previous research focused on 6G chips, and practical research was carried out in the communication field of air, space and sea integration, especially in the field of satellite Internet communication. South Korea also puts the research of 6G technology at the top of scientific research, and claims that the research and development of 6G UHF wireless equipment will be the top priority of Korean communication projects.
In addition to the above domestic patents, the Ministry of Science and Technology launched the 6G technology research and development project composed of 40 scientific research institutions at the end of 10, and held more than 60 seminars. In the field of 6G communication, the standards organization has also given the exact standards of 6G related technologies.
In the future, China will surely make great achievements in 6G and benefit the society.
However, I still use the 4g network. When should I upgrade to 5G first?
