The second "global 6G Technology Conference" will be held online on March 22. The reporter of China Securities News learned from the organizer of the future mobile communication forum that the conference will focus on more than ten 6G key technology scenarios, and several 6G technology series white papers will also be released at the conference.
According to the organizer, through the 6G technology with full spectrum, full coverage, full application and strong security, the future 6G business will show new development trends such as immersion, intelligence and global, forming business applications such as immersive cloud XR, holographic communication, sensory interconnection, intelligent interaction, communication perception, universal intelligence, digital twin and global coverage, which will eventually help human society realize the beautiful vision of "intelligent alliance of all things and digital twin".
At present, 6G for commercial use in 2030 is still in the stage of vision demand research and concept formation, the technical direction and scheme of 6G are still being explored, and the global industry has started the research on 6G.
China has looked ahead
It is understood that on the basis of 5g, 6G will further expand from serving people, people and things to supporting the efficient interconnection of agents, realize the transition from the interconnection of all things to the intelligent connection of all things, become the link between the real physical world and the virtual digital world, continue to improve people's quality of life and promote the transformation and upgrading of social production mode.
China has always attached great importance to 6G development. The 14th five year plan for the development of digital economy released in January this year proposed that the sixth generation mobile communication (6g) network technology reserves should be prospectively laid out, 6G technology R & D support should be strengthened, and 6G international standardization should be actively promoted.
Xiao Yaqing, Minister of industry and information technology, also said during the national two sessions this year that while developing 5g, we should consider the evolution direction and evolution technology route of the next generation communication technology, so as to plan and deploy in advance for the development of the next generation communication technology 6G.
In 2019, the national 6G technology R & D promotion working group, the overall expert group and imt2030 (6g) promotion group were successively established, and all work of 6G was solidly promoted and made positive progress. On June 6, 2021, the imt-2030 (6g) Promotion Group officially released the white paper "6G overall vision and potential key technologies", looking forward to the realization of 6G commercial in 2030, and proposed eight business application scenarios and ten potential key technologies of 6G. The network performance will be greatly improved to help the digital transformation and upgrading of various industries.
In addition, according to the report on the development of 6G communication technology patents issued by the intellectual property development research center of the State Intellectual Property Office last year, at present, there are more than 38000 global patent applications in the field of 6G communication technology, of which China is the main source of patent applications, accounting for 35%, ranking first in the world.
According to the organizer, the innovative ideas and latest achievements of 6G technology research and development will be displayed at this global 6G technology conference. Nearly 100 experts from universities and scientific research institutions, telecom operation enterprises, equipment manufacturers and other countries around the world focus on 6G millimeter wave and terahertz technology, 6G vision and technical requirements, 6G spectrum sharing and coexistence technology, 6G network architecture and key technologies, 6G wireless coverage expansion technology, 6G wireless air interface transmission technology, 6G wireless network security architecture key, heaven earth integration intelligent networking technology Exchange and discuss topics such as key technologies of 6G full scene on-demand service.
In addition, how these highly discussed technologies with great development potential will develop in the 6G era will also be the highlights of this conference.
6g it still takes a long time to realize the application
The communication operator is the leader of 6G pre research. Recently, China Mobile, together with major global operators, released the white paper on 6G application scenarios and analysis, focusing on the definition and analysis of 6G network application scenarios, which will provide an important reference for the development of the information and communication industry.
China United Network Communications Limited(600050) executives also introduced at the company's performance briefing on March 11, China United Network Communications Limited(600050) attaches great importance to network upgrading and evolution and technological innovation and development, and carries out tracking and Research on 5g-a and 6G technologies. The company actively conducts research in the fields of 6G business demand and vision, frequency use, high-frequency communication, intelligent hypersurface, communication perception integration, etc. in March 2021, China United Network Communications Limited(600050) released 6 Zhongrun Resources Investment Corporation(000506) g white paper (v1.0), and put forward the 6G DNA vision characterized by "intelligence, integration, green and credibility". Subsequent companies actively give play to the advantages of scientific and technological innovation, strengthen the joint innovation of industry, University and research, and jointly promote the leading 6G technology.
Communication equipment manufacturers are also an important force in 6G R & D Zte Corporation(000063) , Huawei have launched the research and development of the next generation mobile communication technology 6G.
Communication industry chain companies are also eager to carry out forward-looking layout Gci Science & Technology Co.Ltd(002544) 3 said on the interactive platform on March 17 that at present, the company focuses on increasing the R & D investment of 5g products and solutions, actively tracks 6G key technologies and plans to layout 6G related industries Aoshikang Technology Co.Ltd(002913) 3 revealed on the interactive platform on September 9 that the company is currently communicating with customers on the requirements of next-generation communication technology, negotiating projects related to earth orbit satellite communication, developing and reserving relevant technologies, and has no formal business yet Hytera Communications Corporation Limited(002583) 1 on the interactive platform on January 18, the company, as a member of imt-2030 (6g) promotion group, will continue to pay attention to the performance and development of 6G technology.
However, the industry consensus is that it will take a long time for 6G to be truly applied, which is expected to take 8-10 years. At present, we should still concentrate on 5g construction.
Zhang Yunyong, member of the National Committee of the Chinese people's Political Consultative Conference and general manager of China United Network Communications Limited(600050) Yunnan branch, pointed out in an interview with China Securities Journal during the two sessions of the National People's Congress this year that 6G is still in the stage of white paper, which is just a vision, and the relevant frequency band division has not yet been completed. At present, we should still take a clear-cut stand in 5g construction and devote ourselves to 5g development.
Zhang Yunyong also admitted that 6G technology faces some challenges that need to be solved. For example, because the frequency band is too high, the penetration will be extremely weak. The next rain and even people walking around are likely to interfere with 6G communication signals. At the same time, the 6G base stations to be deployed will also grow on a large scale. According to incomplete estimation, if the 6G communication level is to be equivalent to the current 4G and 5g communication level in China, about 100 billion 6G base stations will be needed. By the end of this year, the number of 5g base stations in China is expected to exceed 2 million. Therefore, the 6G technology itself and the really suitable application scenarios need further research and exploration.
