Still using 4G, 6G is coming? The battle for 6G in various countries has quietly started nearly 20 years ago

There are four key technologies in the field of 6G communications worldwide, mainly terahertz technology, air-space-sea integration technology, deterministic network technology, and AI-based air interface technology. Among the patent applications in these four technical fields, the number of patent applications in China It accounts for a relatively high proportion of the world's total number. Even in some key areas, my country's 6G communication technology has reached the world's leading position.

When China's 5G technology is leading the world, the United States is well aware of its backwardness and has already deployed 6G. What caught the United States off guard is that Huawei has taken the lead in the 6G technology and 31% of national patents have been won by China.

On April 19, 2021, the Minister of Industry and Information Technology revealed in an interview at a press conference that China has now completed the construction of a large-scale 5G network, which will be the largest 5G network in the world, and most prefecture-level cities All will be covered under this 5G network system in independent networking mode.

 

Data shows that as of the end of March 2021, my country has built nearly 820,000 5G base stations, and the three major operators have basically completed 5G terminals, with a total of about 285 million. This covers almost the vast majority of areas, and basically realizes 5G. Technology has all-round coverage without dead ends.

In fact, in the field of communications in my country, not only 5G technology is the leader in the industry, but in terms of 6G, it is also hard to beat by other countries. Ren Zhengfei once gave such an evaluation of my country's 6G technology: still leading.

 

So how powerful is my country's 6G technology?

There are four key technologies in the field of 6G communications worldwide, mainly terahertz technology, air-space-sea integration technology, deterministic network technology, and AI-based air interface technology. Among the patent applications in these four technical fields, the number of patent applications in China It accounts for a relatively high proportion of the world's total number. Even in some key areas, my country's 6G communication technology has reached the world's leading position.

 

The number of applications for terahertz technology in the world is 7,737, and the number of applications in my country is as high as 3,118. In terms of proportion alone, it has exceeded 40% of the total number of applications, which is the highest in the world.

 

The global number of applications for air-space-sea integration technology is 25,509, and the number of applications in my country is as high as 9,159. It is not difficult to see that the proportion is absolute, which has exceeded 31%.

It is worth mentioning that my country is still in the construction stage in these two technical fields. After the technology matures, the leading state is immeasurable.

 

In the other two key technical areas, my country is in a state of catching up with the world, and the distance is gradually shrinking.

 

Although my country leads the world in the number of patented technology applications and can be said to occupy the commanding heights of the industry, the comprehensive strength of my country's domestic communication scientific research enterprises and units is relatively weak, and there is still a gap with other countries.

 

In other words, although the number of patent applications in my country is very large, the advantages of innovative entities are not high, and they are still at a disadvantage compared to other peer companies.

 

At this stage, my country is also increasing the strength of scientific research funds and policy support. Next, a large number of suppliers and scientific research institutions should continue to emerge to continue to promote the continuous advancement and development of my country's 6G communications industry.

 

At present, the research of 6G communication technology on a global scale has just kicked off, and many countries have just stepped into this field. Old-fashioned countries in the field of communication technology, such as the United States, South Korea, Finland and other countries, have immediately begun to develop technology and hardware highlands. Battle.

 

Huawei announced in April that my country's 6G technology will be put on the market in the near future, which is about 2030.

So why is 6G technology so valued by countries? What are its advantages?

According to related reports, 6G technology is by far the fastest communication technology for information dissemination, and the increase in network speed is unquestionable. It is an update and iteration of 5G technology. Cui Baoguo, deputy dean of the School of Information, Tsinghua University, once said that he After years of experiments, the research team found that the 6G network speed may reach more than 50 times the 5G network speed.

 

At the same time, 6G technology relies on the most advanced terahertz frequency band, and its penetrating power exceeds all existing bands. In the 6G era, the accuracy error in the city may be reduced to less than 10 cm, and the accuracy error in the outdoors is not It will be more than 1 meter.

 

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 this coverage method is carpet-like. Once the 6G network is put into use, no matter how remote a mountain village you are. Still on the endless sea, signals can be transmitted accurately and without errors, and there are basically no signal blind spots and blind spots. This... mean that the monthly rent will be very expensive?

 

At the same time, some experts pointed out that 6G communication technology not only covers a wide range and fast network speed, but also cannot reach other technologies in terms of communication information security.

This kind of technology is very likely to be used in the military and political fields. The application of 6G technology may bring about major technological reforms in the field of national defense in our country. In short, the investment and use of 6G technology will definitely bring us earth-shaking changes.

 

The United States began research on 6G as early as 18 years ago. The focus of early research is still on 6G chips, and practical research has been carried out in the field of air, space and sea integration, especially in the field of satellite Internet communications. South Korea has also studied 6G technology. Put it in the first place of scientific research, and declared that the research and development of 6G ultra-high frequency wireless devices will be the top priority of South Korea's communication issues.

 

In addition to the above-mentioned patents in my country, the Ministry of Science and Technology opened a 6G technology research and development project composed of 40 scientific research institutions at the end of 10 years, and held more than 60 seminars. In the field of 6G communications, standards organizations have also given exact information on 6G related technologies. standard.

 

In the future, our country will surely be able to make great achievements in 6G and benefit the society.
