The reporter learned that the current 5G industrialization is still stuck in the”single fire” type of point application. To achieve the”starting prairie situation”, it also faces high terminal costs, insufficient network coverage, unclear business models, and industry adaptation. Insufficiency and many other problems. Industry insiders suggest that multiple measures should be taken to accelerate the application of 5G industrialization, so that 5G can truly become an important support for the digital economy and an important driving force for high-quality development.
5G industrial applications ignited a “spark of fire”
On June 6, 2019, the Ministry of Industry and Information Technology officially reported to China Telecom and China China Mobile, China Unicom, and China Radio and Television issued 5G commercial licenses, and my country officially entered the first year of 5G commercial use. According to data from the Ministry of Industry and Information Technology, more than 700,000 5G base stations have been opened nationwide, and the cumulative number of terminal connections has exceeded 2 Billion, 5G networks are accelerating. On this basis, the application of 5G industrialization has ignited a spark.

The working environment of the personnel.” said Zheng Bo, deputy general manager of Qianye Cement Company.
In June 2020, Zhengzhou City Zhengdong New District Autopilot Bus Line 1 opened.”Autonomous driving buses rely on Beidou satellites and laser SLAM to achieve positioning, and to transmit Beidou signals in real time, to achieve traffic light communication, blind spot warning and other functions, the role of 5G low latency is reflected.” Yutong Intelligent Transportation and said Liu Zhennan, director of planning and control of the autonomous driving department.
According to reports, Henan Province has built the first 5G medical experimental network in the country in the Zhengda First Affiliated Hospital. After conducting remote diagnosis and treatment for several patients in the Xinjiang Hami Central Hospital in the Neurosurgery Office of the First Affiliated Hospital of Zhengda University, Liu Xianzhi, the director of neurosurgery, is remotely instructing a brain surgery in the Zhengdong District of the hospital through a computer screen. .
“Okay, there are no bleeding spots. The operation can be over.” Liu Xianzhi talked to the doctor who performed the operation in the Zhengdong District of the hospital, and pointed to the computer screen and said,”Neurosurgery The surgical requirements are very high. When there is no 5G, the operation video transmission is not smooth and the definition is not enough. Now you can see that it is very clear and there is no delay.”
In the epidemic prevention and control, 5G technology is also promising. On January 10, 2021, Wuhan University Zhongnan Hospital arranged 5G vehicle-mounted mobile CT to assist Hebei to help Hebei quickly diagnose new coronary pneumonia. According to Ye Naili, the chief technician of the Medical Imaging Department of Zhongnan Hospital who assisted Hebei, the characteristics of”vehicle + 5G” mobile high-bandwidth transmission are in line with the needs of clinical diagnosis services under complex epidemic prevention and control conditions, which can speed up the efficiency of patient diagnosis and treatment and reduce the risk of infection of medical staff .
On January 17, 2021, the Tianjin Port traditional container terminal full-process automation upgrade project realized full operation. The project integrates 5G technology, Internet of Things, artificial intelligence, cloud computing and other technologies, and realizes large-scale group applications of unmanned automated container yard bridges, unmanned electric container trucks, unmanned intelligent unlocking stations and unmanned container quay cranes .
In Shenzhen, the local area has achieved full coverage of the city’s regional 5G independent networking, and the construction density of 5G base stations is leading the country. The Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, as the general promotion agency, has united relevant enterprises, associations, alliances and other entities to form the”Shenzhen New Generation Information and Communication Industry Cluster” to cultivate 5G, integrated circuits, new displays, and related linkage industries. Integration of innovation and development.
At the same time, the integration of 5G with smart manufacturing, tourism, UHV substations, drones, logistics and other industries is also continuing to advance.
The”Industrial Internet Innovation Development Action Plan (2021-2023) recently issued by the Ministry of Industry and Information Technology It is proposed that by 2023, my country will build 30 5G fully connected factories in 10 key industries.
There are still problems in the development of 5G industrialization in order to become”a prairie fire”
Accelerating the application of 5G industrialization still faces high terminal costs. , Insufficient network coverage, unclear business models, insufficient industry adaptation and many other problems.
——The 5G industry chain needs to be improved, and the gap in some areas is still large.
China Unicom Group Product Center General Manager Zhang Yunyong introduced that China has achieved good results in 5G technical standards and patents, but high-end data communication chips, high-speed digital-to-analog conversion chips, high-end CPU/FPGA, high-end Core devices such as high-performance radio frequency front-end devices still rely on imports, and there is still a big gap between the instruction set and chip design and other technical barriers compared with the leading chip companies in Europe and the United States.
——5G modules and terminals are expensive, and network coverage is still insufficient.
Zhang Yunyong introduced that due to the high frequency of use of 5G, it is estimated that the density of 5G sites will be at least 1.5 times that of 4G, and the scale of network investment will be about 4 times that of 4G. Therefore, the initial stage of 5G network deployment will face greater financial pressure. In addition, in the 5G era, there are various types of terminals in the 5G era, in addition to smart phones. The core of its communication is 5G modules. In the initial promotion, it faces problems such as small scale, high cost, low profit, and slow results, and high cost constraints A quick promotion.
In the view of Zhao Jie, deputy secretary of the Party Committee of the First Affiliated Hospital of Zhengzhou University and director of the National Telemedicine Center, 5G is of great value in the field of telemedicine, but other medical institutions in the province have not yet fully covered the 5G network. Remote consultation , Remote surgical guidance, remote voice treatment and other functions are temporarily unable to be deployed on a large scale.
Wang Xiangning, head of the 5G UAV project of China Unicom Research Institute, introduced that 5G UAV is one of the important directions of 5G industry applications. At present, 5G UAV tests are basically carried out using the ground network. However, the existing network coverage is still insufficient, and it is not specifically designed for aerial targets. The performance quality needs to be improved.
——Insufficient integration of 5G and vertical industries.
The”Fourteen Trends of China’s Electronic Information Engineering Technology Development (2021)” recently released by the Information and Electronic Engineering Department of the Chinese Academy of Engineering and the China Information and Electronic Engineering Technology Development Strategy Research Center proposes that the current 5G network is accelerating Construction, but its promotion and perfection and vertical integration with various industries still face challenges.
Taking the medical industry as an example, Zhao Jie introduced that at present, including Huawei, Qualcomm and other manufacturers launched some 5G modules and routers have insufficient adaptability to existing medical equipment, resulting in 5G networks not being stable enough for medical applications.
The integration and application of 5G and power systems are also facing difficulties. According to Li Yongjie, who is in charge of the Technology Development Department of the Information and Communication Company of the State Grid Henan Electric Power Company, one is that the lagging of uRLLC and mMTC standards brings uncertainties to power applications; the other is that 5G network characteristics affect the existing power security protection architecture, security equipment and network Management poses new challenges. The 5G application security protection system and protection plan are still in the research stage, which restricts the promotion and application of production control services; third, a large number of power grid production services will be carried on the operator’s 5G public network in the future. How to realize the power 5G business The whole process control is facing challenges.
——The 5G business model is unclear, and the application ecology is lagging behind.
Zhao Jie introduced that the business model of 5G in medical applications is still not clear. Take the Zhengda First Affiliated Hospital as an example. Although the hospital has established a 5G network, how does the operator charge and how to medical equipment? The calculation of the flow rate is yet to be determined.
Some local government officials said frankly that the existing 5G application scenarios have many local point applications, fewer vertical industry application scenarios, and there are not enough mature and replicable scenarios.
Experts suggest multiple measures to accelerate the application of 5G industrialization
Relevant experts suggest that multiple measures should be taken to accelerate and optimize the application of 5G industrialization. Let the”single fire” form a”powder prairie trend” and help high-quality economic development.
The first is to increase policy support to accelerate 5G infrastructure construction and industry adaptation research.
Zhang Yunyong suggested to increase the co-construction and sharing of 5G networks, avoid repeated construction of network infrastructure, and ease the pressure on construction funds; in the initial stage of 5G commercial use, special subsidies can be used to guide the large-scale development of 5G module manufacturers. Stimulate the enthusiasm of the upstream and downstream of the industrial chain, and ultimately achieve the goal of reducing costs. At the same time, it is recommended that relevant departments actively guide the 5G vertical industry cooperation model.
Zhao Zhanjun, Dean of the Henan Branch of China Mobile Design Institute, suggested that on the one hand, speed up the free opening of public institutions to the construction of 5G base stations, promote the two-way open sharing of communication base stations and social tower resources, and reduce the cost of 5G network construction; , To reduce electricity costs by subsidizing electricity prices for 5G base stations, supporting information infrastructure for smart meter transformation, and simplifying the process of applying for telegraph installation.
Li Yongjie suggested that, in the power industry, conduct 5G application demand surveys for power generation, transmission, transformation, distribution, and use, and jointly carry out adaptability research and business adaptability testing.
The second is to promote pilot projects and support pilot projects.
Zhao Zhanjun suggested that a batch of 5G new technologies, new products, new business forms, and new model demonstration projects with obvious industry leading role should be identified, and focus on the construction of major projects such as the industrial Internet, smart cities, subways, and high-speed rails. Demonstration applications of 5G in major projects can be given certain rewards to play a leading role in the first trial.
The third is to increase investment in R&D and innovation to open up the upstream and downstream of the industry chain.
Wu Liangping, vice minister of Huawei’s Wireless Industry Development Department, believes that accelerating the pace of 5G commercialization and simultaneously advancing the development of the entire 5G ecosystem such as chips, terminals, and network equipment. It is necessary to make up for shortcomings in the industry chain as soon as possible. The investment of enterprises in R&D and innovation forms a virtuous circle.
Zhao Zhanjun suggested that we should increase efforts to cultivate key technological enterprises, build a batch of”5G+cloud+AI” industrial bases with top-level hardware conditions and give full play to R&D and application capabilities, and support enterprises in digitalization based on demand Transformation.
Fourth is to strengthen the ecological construction of 5G talents and improve the digital skills of workers.
Experts suggest to accelerate the training of compound 5G talents involving information majors, communications majors and industrial Internet. Accelerate the ecological construction of 5G talents, build a group of regional digital skills public training bases with outstanding functions and resource sharing, support large-scale backbone enterprises in the digital economy and scientific research institutes to jointly build talent training bases, and better and faster complement 5G talents Short board.
