The technological evolution of mobile communication industry is a decade. In the past 30 years, the development from 2G / 3G / 4G to 5g has not only brought about a huge increase in the network transmission rate, but also provided a solid foundation for the transformation of digital intelligence in thousands of industries and opened a new chapter in the digital intelligence life of the public with the integration and innovation of 5g technology in the fields of production and life. Recently, at the "5g continues to evolve and build a 5gigaverse 5green society" conference held during the "2022 Huawei global analyst conference (has 2022)", five representatives from the Chinese Academy of communications and communications, operators, equipment providers, vertical industries and consumer industries "gathered" to talk about the development status and challenges of 5g evolving new technologies and the attendant innovation opportunities from all angles. Accelerate to 5.5G in the "fast lane" The development of consumer application (TOC) and industry digital (tob) services puts forward higher requirements for 5g network performance. In terms of personal business, with the application of ultra-high definition video business, including immersive experience and the development of AR business, "the traffic of mobile network will increase several times or dozens of times in the next five years and ten years." Ding Haiyu, director of the Institute of wireless and terminal technology of China Mobile Research Institute, said, "it is expected that by 2025, the Dou (average monthly Internet traffic per household) of individual users will reach 50g ~ 100g, and the maximum will exceed 250g in 2030." The application development of 5g industry has entered the "fast lane", and the pilot application has begun to replicate on a large scale. According to Wang Zhiqin, vice president of China Academy of information and communications, the "blooming Cup" 5g application solicitation competition has been held for four consecutive years. The number of participating projects has increased from 330 in 2018 to 12000 in 2021. The number has jumped rapidly, involving more than 10 fields such as industrial Internet, medical treatment and transportation. Among them, 33% have been commercially available and 15% can be replicated on a large scale. Facing the future, 5.5G is the focus of the industry, and the technical standard is advancing to R18. Facing the needs from all walks of life in the business process, the ability of the network is required to be continuously enhanced. Gan bin, vice president and chief marketing officer of Huawei's wireless product line, proposed that on the basis of 5g gigabit network, "5.5G (5g advanced) will provide ubiquitous 10 Gigabit experience and 100 billion connectivity", continue to accelerate the integration of the digital world and the physical world, and more truly reflect the situation of the physical world. "R18 is the focus of the industry on 5.5G. R18 is expected to start this year, and rel-18 is planned to be completed in December 2023." According to Wang Zhiqin, 5g has entered the stage of large-scale commercial use. In the process of follow-up technology industry and application development, it is necessary to comprehensively layout the technology standards and application industry to promote industrial development in an orderly manner. Policy traction and industrial cooperation boost 5g upgrading Throughout the 5g journey, policies have pointed out the development direction, and standards, R & D and commercial applications have been promoted in an orderly manner. In 2013, the Ministry of industry and information technology, the national development and Reform Commission and the Ministry of science and technology guided the establishment of imt-2020 (5g) promotion group to carry out technical standards, product research and development, support commercial use, and accelerate research and development through 5g technology research and development test; The Ministry of industry and information technology released the 5g frequency plan in 2017 and allocated 5g commercial spectrum in 2018; The Ministry of industry and information technology issued 5g commercial license in 2019; In 2019, the 5g application industry matrix was established and the "blooming Cup" 5g application competition was held for four consecutive years to promote the formation of 5g integrated application ecology. In order to implement the 14th five year plan, the Ministry of industry and information technology will formulate 5g development plan in 2020; In July 2021, the Ministry of industry and information technology and other ten ministries and commissions jointly issued the 5g application "sailing" action plan (2021-2023). 5g commercial speed exceeded expectations, and 5.5G is already on the line. "China's 5g scale deployment has also promoted the rapid maturity of the global 5g industry." Wang Zhiqin pointed out that China took the lead in completing the testing and large-scale commercialization of 5g m-mimo on C-band and 2.6GHz, accelerating the global commercial deployment of TDD medium frequency band, and promoting the rapid opening of global 5g commercial network. Industrial cooperation and jointly promote the global unified 5g evolution standard. In August last year, China Mobile and Huawei held the 5g advanced (5.5G) innovation industry summit, aiming at the three goals of "excellent network, smart and simple, low-carbon and efficient", promoting the development of 5.5G, jointly pushing the 5g industry to a new level, and injecting stronger impetus into the digital intelligence transformation and high-quality development of various industries. "Every generation of wireless technology is an industry explorer who constantly raises industrial problems and then solves them." Gan Bin said that in order to achieve the vision goal of 55g 10 Gigabit experience and 100 billion connection, Huawei and industrial partners need to continue to explore in the directions of Super bandwidth, uplink spectrum reconstruction, elaa-mm, green air interface and endogenous intelligence, so as to upgrade the wireless network capability. Wang Zhiqin said that 5g has entered large-scale commercial use. In the process of follow-up technology industry and application development, it is necessary to comprehensively layout the technology standard and application industry, continuously improve the bandwidth capacity, further enhance the uplink capacity, provide more flexible networking services and orderly promote industrial development. 5g continuous evolution, integration, innovation and application can be expected in the future "5A + AI will promote the integration of business models", said Dr. Jiang Shuhong, vice president of vision + ar. the core ability of high-precision positioning of large space computing based on 5g will accelerate the popularization of AR applications. Interactive sharing and AI applications under 5g can bring immersive experience to users and provide a broad stage for the development of emerging formats of cultural and tourism industries such as immersive scenic spots and museums. At the same time, AR based remote office, remote maintenance and other application scenarios will also drive the continuous evolution of 5g network towards lower delay and large uplink and downlink bandwidth. In terms of intelligent operation management of supply chain, it is an objective requirement to quickly and reliably establish a new production line and ensure the stability of the production line in the case of wireless. "The differentiated production demand of multiple varieties and small batches has brought the problem of uneven utilization of each production line", said Gu Jun, vice president of supply chain performance and digitization of Schneider Electric China. The wireless deployment based on 5g can greatly reduce the connection complexity, and the stable low delay performance can effectively meet the relevant requirements of industrial control system, providing an important starting point for improving the utilization of production line. According to the research on China's 5g development and economic and social impact (2021), the total economic output driven by 5g in 2021 will be 1.3 trillion yuan, both directly and indirectly increasing by more than 30% compared with 2020. "From the perspective of 5g technology application and innovation, 5g technology needs to be continuously developed in the future." Wang Zhiqin said that the development of 5g should continuously expand the 5g connection capacity, expand the application boundary and enable thousands of industries. "Ubiquitous Gigabit experience and 10 billion connection can be provided by 5g at present", Gan Bin said that the 5.5G of the forward half generation will also follow the law of industrial development. From vision to industrial construction, wireless communication will continue to break through the capability boundary, and continue to explore and innovate in improving spectrum efficiency, moving from centralized to distributed elaa-mm, and providing ubiquitous coverage for terminals. "It's better to rise and act than sit and talk". The development vision of 5.5G has been put forward, and the further capacity definition and evolution needs will be gradually clarified. The future oriented industrial vision requires the concerted efforts of partners in the communication industry to overcome difficulties, promote 5g to move forward in an orderly manner in terms of technological innovation, standard formulation, application and industrial supporting, and work together to reach the critical period of 5.5G development.
