Preface
Looking at China's 5G technology and the exposure of money, countries have also realized the importance of communication technology, and have begun to lay out research in the 6G era, and have begun to apply for patents in full swing.
To date, the United States accounts for 35.2% of the number of 6G patent applications, and Japan, which once had brilliant communication technology, now accounts for 9.9%, and it is even announced that 6G equipment has been deployed.
Seeing that countries around the world are so focused on the research and development of 6G technology, how much share does China occupy in 6G patents?
The 6G of the future
If 2G is an ox cart, then 3 G is a bicycle, 4 G is already a car, and it is not an exaggeration to say that it is a high-speed rail at 5 G.
6G is the sixth-generation mobile communication standard, which is the abbreviation of the sixth-generation mobile communication technology based on conceptual wireless networks.
Qiao Jianyong, vice chairman of the China Institute of Communications and president of Beijing University of Posts and Telecommunications, said that in the future, 6G will become a ubiquitous communication network, and the communication network will move towards a smart development trend.
The existing network structure for individual communication can no longer meet the needs, and the network structure of communication-sensing-computing convergence must be redesigned, including the Internet of Things, unmanned aerial vehicle (UAV) networks, satellite communication networks, dense cellular networks and other forms.
Is that 6 G just going faster? Not
It is conceivable that as long as you move your fingers, you can accurately control the mine at a depth of more than 240 meters and carry out remote control "one-click coal mining"; A surgeon can even control a surgical robot from a distance of 300 kilometers to perform difficult surgical operations.
4 G is tens of M/s of data, 5 G is the speed in gigabytes, 6 G may even reach the terabyte level, in short, the speed of the network will be faster and faster is just the appearance, the future of the Internet will link more fields.
6G expands the traditional field of mobile communications, combining multiple fields such as communication and artificial intelligence, and transforming from a single interconnected service to an integrated information service, which can bring new development momentum to the industry and improve production efficiency.
The 2024 World 6G Technology Conference opened in Nanjing, and relevant personnel from China, the United States, Japan, South Korea and other countries jointly formulated a general plan for 6G research and development.
Huang Yuhong, head of communication technology at China Mobile, said in an interview: "In 2029, the standard for 6G will be formulated, and by 2030 or so, 6G will be commercialized." ”
According to some scholars, in the future, 6G technology will be applied to space communication, intelligent interaction, tactile networking, emotional and tactile interaction, multi-sensory mixed reality, collaboration between machines, unmanned driving, etc.
With the rapid development of network, display technology, perception and imaging technologies, 6G technology, VR, AR and other technologies will replace traditional smartphones and become an important means of people's daily life and work.
According to the report "6G Typical Scenarios and Key Capabilities" released by the China Academy of Information and Communications Technology, the scale of networks will grow by 100 billion yuan in the future, and the number of connections will reach more than 90%.
Immersive services based on emerging devices such as XR devices and holographic devices are expected to contribute more than half of the average monthly traffic, forming a huge market of "100 billion terminal connections and trillions of GB of monthly traffic" for 6G.
Current 6G
At present, the international development of 6G is still at the level of technical discussion, and a common architecture and core technology have not yet been formed.
Continental has already carried out 6G technical experiments last year, and has also carried out relevant research on 6G architecture and technical solutions this year, laying a solid foundation for the further development of 6G in the future.
Wang Zhiqin, leader of the 6G promotion team and vice president of the China Academy of Information and Communications Technology, said:
"Now the whole mobile communication network is a very large network system, there are many base stations, on the basis of the base station, I hope to be able to do some perceptual work.
To do low-altitude economy, directly upgrade on the base station, it has the ability to perceive, so that the UAV can be managed in the airspace.
There are also some traffic intersections, after upgrading these base stations, you can see the entire traffic flow, which is used as some traffic management. (Interview with Beijing News)
Li Zhengmao, Chairman of the World Cloud Network Broadband Industry Association, said:
"In order to meet the needs of immersive, intelligent, and global services and application scenarios in the 6G era, the 6G network will combine technical elements such as communication, perception, computing, data fusion, and intelligent security to build a 6G network with high-speed cloud-network integration, integrated synaesthesia computing, elastic intelligence, endogenous security, and Internet of Everything, build a more efficient and connected digital infrastructure, and better support the development of the digital economy." (Guangming.com)
Li Zhengmao said that at present, corresponding research has been carried out internationally, and some basic consensus has been reached on the research of 6G, and some important technologies are gradually concentrated.
However, the specific technical solutions for 6G have not yet been unified, and relevant standards have not yet been launched, and Li Zhengmao called on "the global industry to continue to innovate and work together to avoid the fragmentation of 6G standards in the future".
Global 6G technology patents
The rapid rise of China's communications companies in the 5G field has demonstrated China's self-reliance in science and technology, laid a good foundation for China's development in the 6G field, and demonstrated China's huge advantages in the 6G field.
The United States, a communications powerhouse, owns 35.2% of the world's 6G patents, while technology giants such as Qualcomm and Cisco continue to increase their investment in 6G, which has become a key factor for the United States to gain a competitive advantage in 6G.
Japan has a strong foundation in communication technology, accounting for 9.9% of the world's research results in 6G.
Japan, as a former communications technology powerhouse, has done a good job in 6G, and it is expected to return to some of the advantages of the 3rd and 4G eras.
China ranks first in the world in the number of patent applications in 6G, ranking first in the world with a share of 40.3%, and is the first power in the field of 6G technology.
The United States and Japan have reached a consensus on the development of 6G, forming a new cooperative development model, and the two sides will exchange technology and encourage cooperation between enterprises on both sides.
On the one hand, the U.S. government's policies and initiatives against China's 5G technology equipment are trying to restore its position in the field of science and technology by forming an international coalition for 6G.
The first 6G device?
Just some time ago, a number of Japanese communication companies jointly announced that they had developed the world's first 6G wireless communication device.
Japan's latest 6G device can reach 100 Gbps/s, which is more than 500 times higher than the average download rate of existing 5G smartphones.
Xiang Ligang, an observer of China's communications industry and an expert in intelligent Internet research, said when asked by reporters:
We generally believe that 6G networks will be more than 10 times faster than 5G.
Japan's related technology is 500 times faster, and it may use carrier aggregation technology to aggregate more frequencies to improve speed. However, making the speed so fast has high requirements for network equipment, heat dissipation, and cost. (Interview with Guangming.com)
In fact, the industry now has a clear consensus on the development direction and vision of 6G, so Japan's achievements and some of the technologies behind it are a bit "out of tune".
The so-called new devices are only 6 G high-speed radios, not full 6 G network systems and devices, and secondly, the signal propagation range of the devices is limited to 100 meters, which limits the practical application of this method.
In other words, the technology is not really useful, but just an experiment with future technology.
Looking to the future
The development of 6G technology has become a global scientific and technological competition, and countries are actively competing for their own future.
While Japan has made remarkable progress in 6G, China's patents and technological prowess cannot be underestimated.
It is reported that the country has set up a 6G promotion team in 2019 to systematically promote demand, technology, standards and international collaboration to carry out 6G technology experiments.
At the same time, the 6G promotion team also published a series of technical solutions such as "6G Network Architecture Outlook" and "6G Wireless System Design Principles and Typical Characteristics", laying a solid foundation for the transition of 6G from "Internet of Everything" to "Intelligent Connectivity of Everything".
On April 27 this year, the annual meeting of the Zhongguancun Forum "Artificial Intelligence Theme Day - 6G Innovation and Development Theory"
, there is another bombshell news.
Zhongguancun Panlian Institute has cooperated with China Mobile, Lenovo, Vivo and other forces to build a 6G ultra-large-scale MIMO cloud-based wireless network prototype verification system, which has great reference significance for the development of 6G terminal products in mainland China.
In addition, as early as February 3, China Mobile 01 satellite was successfully launched, which is the world's first 5G and 6G space-ground integrated network low-orbit test satellite.
At an orbit of about 500 km, this satellite has the advantages of low latency and fast data transmission, laying a solid foundation for the future 6 G ground-to-air networking network platform!
It can be said that China is struggling for the 6G mainstream of 6G technology power, and it can really be said that it is far ahead.
In order to promote the development of 6G, government departments and enterprises have carried out a lot of funds and energy, forming a good situation of government-enterprise cooperation.
The 6 G will bring great changes to the production and life of society.
The successful application of 6G will certainly provide new development opportunities for various industries and promote the economic growth of all countries in the world.
It can be said that the achievements of China's 6G research and innovation have not only made great contributions to the innovation of science and technology in the world, but also to the development of the entire human society.
epilogue
We firmly believe that with the cooperation of all countries around the world, 6G research and innovation will achieve great breakthroughs, and mankind will usher in a bright tomorrow.
