The 2022 World 5G Conference is just around the corner, and the research and development of 6G(the sixth generation mobile communication standard) technology has gradually attracted extensive attention in the industry.
Wu Hequan, academician of the Chinese Academy of Engineering and chairman of the Future Mobile Communication Forum, said in a speech at the 2022 World 5G Conference Foresight Forum held this morning that 6G will face challenges such as demand, spectrum, high cost and ecological construction. In addition, compared with the previous mobile communication technology, China's 6G research and development is facing a more severe international situation. Therefore, Wu suggested that international exchanges and cooperation should also be strengthened to contribute Chinese standards.
In addition, Zhang Ping, academician of the Chinese Academy of Engineering, also analyzed and judged the development situation of the global 6G. Zhang Ping said 6G development is now facing a fierce international competition pattern, which is crucial to a new round of technological innovation and industrial transformation. China, the United States, Finland, the European Union, Japan and South Korea are all planning to deploy 6G in advance.
6G faces fierce international competition
At present, global 6G is facing a fierce international competition pattern, which is crucial to a new round of technological innovation and industrial transformation. China launched the 6G research at the same time as the rest of the world, and set up the IMT-2030 (6G) promotion group and the overall expert group.
Zhang Ping said that 6G is not only reflected in the speed of the enhancement, in the intelligence and universality will have a greater change, compared with the previous generations of mobile believe, is a deeper change, countries need to develop some core technology to change. In view of the fierce international competition, countries have come up with their own skills, China in the IMT-2030(6G) working group, put forward a variety of innovative technologies, the United States put forward flexible and intelligent next generation network communication technology plan, the European Union, Finland, Japan, South Korea and other countries have put forward their own technologies.
How much impact will 6G have on the digital industry? Mr Zhang thinks, 6 g in digital products manufacturing, digital products, services, and the application of digital technology, digital elements drive the improvement of the industry, digital elements of industry, etc., will show powerful: integration of 6 g of synaesthesia, entities of environmental awareness, the digital implementation of virtualization with advanced supporting role; With the integration of communication and perception, the past separation of communication and perception becomes one, which can help the metaverse to realize virtualization and digitalization. In terms of digital currency, 6G combined with blockchain can achieve technical security transactions and data protection; 6G also enables multi-dimensional sensory connectivity.
Zhang Ping said, with 6G to drive the high-quality development of domestic digital industrialization in two aspects: on the one hand, to promote scientific and technological innovation, for 6G dominance; On the other hand, expand domestic demand to promote 6G technology, and benefit the future social development.
6G to dredge "blocking points" with innovative technology
6G now faces four major challenges.
First, there is an urgent need for breakthroughs in developing the basic theory of the 6G. This is a common challenge facing the whole world. From 1G to 5G, Shannon's information theory, which relies on continuous development, has reached its performance limit and is in urgent need of change. The whole industry needs to find new technological innovations as a guide to dredge the root blockages. The second is the 6G essential support link in China, the basic core technology is relatively weak, need to do more work in some key technology devices. Third, the "killer" application platform is still lacking. Fourth, the open source ecology is not complete.
6G technology is also undergoing great changes. There is room for innovation in semantic communication technology, computing power network technology, intelligent simple network technology, communication perception integration technology, space-space fusion technology and blockchain technology.
The high-quality development of 6G requires several things to be done well on the network side. First, the deployment of network infrastructure, including the deployment of satellites, drones and other aerial facilities, and the deployment of facilities supporting AI, cloud and other new technologies. Second, to do a good job in the new air port and network architecture of endogenous intelligence, to achieve cloud edge and end collaborative deployment; The third is to do a good job in the deployment of computation-aware network, with communication, computing, storage as one of the information system, computing resources unified modeling measurement, unified management and control, intelligent scheduling, there is a great room for innovation.
In promoting the development of 6G industry and technology, it is the first step to do a good job in the infrastructure construction of 6G communication and realize the infrastructure deployment of cloud edge collaborative computing power. Moreover, it is necessary to combine the demands of XR, metaverse and other new consumption modes and business innovation modes to promote ultra-high-speed and highly reliable data transmission. Intelligent holographic radio, computing force sensing network, intelligent simple network, network slicing, cloud network collaboration and blockchain technology maturity and commercial applications.
How far is 6 grams from us?
Communication technologies change like no other. Generally speaking, standards come before applications.
However, it should be noted that standards often come from the direct feedback of scenario-scale application, and 6G is no exception. Instead of competing for 6G technologies, the industry is looking for a real test field for standards. At present, although the industry has not developed a unified standard for 6G, it has reached a preliminary consensus on the commercialization process of 6G, and planned the prototype of a time line. Last year, Wang Jianzhou (former chairman of China Mobile) said that 6G will be commercially available by 2030.
When 5G is not yet fully popularized, many people joke that 6G is destined to "get up early and catch up late". However, it is not too much to prepare for the next generation of communication technology in advance and carry out forward-looking research and development and patent reserve by referring to the development law of the mobile communication industry of "using, doing and watching the next generation".
After all, at the strategic level, it may well be the key to seizing the commanding heights of the information industry in the future.
According to Liu Guangyi (chief expert of China Mobile Research Institute), based on the development process of 5G, the whole 6G research and development will be roughly divided into two stages. Phase 1 (2018-2025) : definition of vision and requirements, research and verification of key technologies, system concept design and prototype verification; In the second phase (2026-2030), 3GPP starts the research and development of relevant standards, the promotion of "end-to-end" industrialization, business and application cultivation and commercial deployment.
Abroad, Finland took the lead in publishing the world's first 6G white paper. Horizon2020 launched the 6G research project of "Intelligent Networks and Services". The United States has been paying attention to the field of terahertz and space-space integration technology, forming a low-orbit satellite Internet formation with SpaceX, Amazon, Astra and Boeing as the core members. 6G research in Japan and South Korea is biased towards school-enterprise cooperation. LG and Samsung have established 6G research centers and released 6G white papers, covering 6G vision, evolution trend, application scenarios, standardized timetable, etc.
When we put the demand for the development of communication network, and maslow's hierarchy of needs of analogy, we is not hard to find, the latter from the perspective of human motivation, the people demand from low to high in turn divided into physiological, safety, social, respect and self-realization, the former from 1 g development up to now, from the basic meet the demand of communication between people, to meet the demand of various life scenes, To high-speed connections between people and things, and between things and things, communication technology has become the link between the real physical world and the virtual digital world.
But the demise of Moore's Law makes us pause for thought: Is 6G talk premature?
