How to do the next 6G?, 5G leads, 4G runs parallel, 3G breaks through, 2G follows, 1G blank is still emerging | 5G | blank
5G is still thriving, and the future of 6G has arrived. The 2023MWC Shanghai World Mobile Communications Conference is currently underway, and as the next generation of 5G communication technology, 6G has become a hot topic.
Public information shows that compared with 5G, the transmission capacity of 6G can be increased by 100 times, and the network delay may also be reduced from milliseconds to microseconds. Second, the 6G network will be a fully connected world that integrates terrestrial wireless and satellite communications. Achieve seamless global coverage by integrating satellite communications into 6G mobile communications. In addition, 6G will use the terahertz frequency band, which is a much higher frequency band than 5G. This means that the "densification" of 6G networks will reach an unprecedented level. By then, people will be surrounded by small base stations.
The reporter learned from the 2023 MWC conference that the three major domestic operators have started to layout the 6G industry. China Telecom stated that at the national project level, they have made advance arrangements for key areas such as 6G network architecture and 6G integrated space and space. Currently, they are leading the "National Key R&D Plan" projects such as 6G network architecture and key technologies, and 6G satellite networking.
In terms of innovation capability, China Telecom has independently developed a wireless simulation system for 6G, becoming one of the few operators in the world with complete wireless simulation capabilities. In addition, China Telecom has taken the lead in proposing innovative concepts such as full spectrum fusion and near-field cellular technology for 6G in the industry, focusing on key technological directions of 6G. It has conducted joint research with universities, research institutions, and industry partners, and has achieved the first prototype verification of RIS embedded in symbiotic wireless communication theory in the industry. It has also developed the industry's first multi-user full duplex prototype based on a new air port, and conducted on-site testing of wireless air port AI mobility enhancement for the first time in the industry.
China Mobile was one of the earliest companies in the world to conduct 6G research, tackle multiple iconic technologies, and cultivate and incubate a series of original technologies. At the conference, they officially launched the 6G public testing and verification platform, providing an open and scenario based joint research and development and testing environment for industrial partners, supporting the verification of various new business and application scenarios, lowering the threshold for 6G key technology research and development, and accelerating the breakthrough of original technologies. At the same time, the "6G Collaborative Innovation Prototype Platform Achievements" were also released, collaborating with various partners to promote the integrated development of the 6G industry; Release the "Skywalker Low Altitude Economy Pioneer Action Plan" to jointly create a better future for the low altitude economy.
China Unicom stated that it will comprehensively layout around the 6G network, conduct research and experiments in key areas such as intelligent metasurfaces and terahertz communication, and work together with partners to jointly build 6G network standards.
In addition to the three major operators, the reporter also learned from the conference that Nokia Bell has successfully completed key technology tests such as 6G terahertz communication, synesthesia integration, and AI air port organized by the China IMT-2030 Promotion Group, and achieved excellent results. Under their promotion, the China IMT-2030 Promotion Group and the European 6G-IA signed a memorandum of understanding to jointly promote 6G innovation and development. Nokia Bell has set its technological innovation goals for the next 10 years as "6CM", which includes 6G, CFN, and Metaverse, highlighting the importance of 6G.
Coincidentally, on June 28, 2023, the opening day of the MWC Shanghai World Mobile Communication Conference, the Ministry of Industry and Information Technology officially released the new version of the "Regulations on Radio Frequency Division of the People's Republic of China", which will be officially implemented from July 1. In this revision of the Division Regulations, the Ministry of Industry and Information Technology took the lead in dividing all or part of the 6425-7125MHz frequency band into IMT systems worldwide.
The 6GHz frequency band is the only high-quality resource with high bandwidth in the mid frequency band, balancing coverage and capacity advantages. It is particularly suitable for 5G or future 6G system deployment, and can leverage the advantages of the existing mid frequency band 5G global industry. Industry insiders believe that the new version of the "Division Regulations" is conducive to stabilizing the expectations of the 5G/6G industry, promoting global or regional consistency in the division of 5G/6G spectrum resources, providing necessary intermediate frequency band frequency resources for the development of 5G/6G, and promoting innovative development of mobile communication technology and industry.
In the past 30 years of development, China's mobile communication industry has achieved a leapfrog development with a gap in 1G, followed by 2G, breakthrough in 3G, simultaneous operation of 4G, and leading by 5G. At present, China has built the world's largest and most advanced broadband network infrastructure, with 60% of 5G base stations and 60% of 5G users worldwide.
After leading the way, can China's mobile communication industry continue to be at the forefront? It is understood that the commercial landing of 6G will take place around 2030, which means that the next 3-5 years will be a crucial window for China's 6G industry to develop.
