Infrastructure maniac
Everyone has heard of the importance of 5G technology, but not everyone understands it. As a new generation of information and communication technology, compared with 4G, 5G has the technical characteristics of "ultra-high speed, ultra-low delay and ultra-large connection", which can not only further enhance the user's network experience, bring faster transmission speed to mobile terminals, but also meet the application requirements of the Internet of Everything in the future and give the Internet of Everything the ability. It is considered as the representative technology of the new round of industrial transformation, an important driving force to support future economic and social development, and an important part of national strategic planning.
Therefore, in the year when 5G was commercialized, China, known as the "infrastructure madman", always led the world in the construction of 5G base stations. The data shows that by the end of September, there were more than 690,000 5G base stations nationwide, basically achieving 5G coverage in prefecture-level cities. This year, the construction target of 500,000 5G base stations was completed ahead of schedule, and the cumulative number of 5G terminals has exceeded 65.438+600 million.
Among them, China Mobile has opened more than 350,000 5G base stations across the country, and realized the commercialization of 5G networks in all prefecture-level cities and some key counties; China Telecom and China Unicom have built 300,000 5G base stations; Last month, China's fourth largest operator, China Radio and Television, was officially unveiled, and it quickly took the pace of 5G commercialization.
It is worth mentioning that in May this year, China Mobile has signed a framework agreement with China Radio and Television. China Mobile can not only solve the problem of network coverage in marginal areas through 700MHz frequency, but also earn income from radio and television to reduce costs. According to the announcement, China Radio and Television paid for the use of China Mobile 2.6GHz? 5G network, transmit network resources, and pay corresponding network operation and maintenance fees. , but did not specifically disclose the details of the settlement. In addition, China Mobile will jointly build a 700MHz? There is a high proportion of equity in the 5G network.
In August this year, Shenzhen achieved full coverage of 5G independent networking, becoming the first city in the world to enter the 5G era. So what is independent networking? According to the introduction, there are currently two networking modes for 5G networks: independent networking (SA) and dependent networking (NSA). Non-independent networking is to transform the existing 4G network and increase 5G equipment (this is the way for some European countries to eliminate Huawei's 5G equipment selection); A good understanding of independent networking is to build a brand-new network. Its advantage is that it can support more broadband and more usage scenarios, give full play to the characteristics of 5G networks, and promote the full implementation of 5G applications. The three major operators also said that they will start global commercialization of independent networking from September.
Landing and survival challenges
It stands to reason that the pace of infrastructure construction and commercialization of domestic 5G base stations is not slow, but why are there still few application scenarios? The biggest difficulty is that it is not yet possible to seamlessly connect 5G technology with various vertical industries. Wen Ku, director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, once said: "In the next three years, China will be in the leading-in period of 5G development, so we should adhere to a moderately advanced pace of construction and form a benign development model of 5G that promotes use through construction. 」
In other words, the application of 5G is still in the early stage, but there are still many cases of large-scale landing of 5G industry in recent years. Especially under the special circumstances of the global COVID-19 epidemic, 5G and related technologies such as AI, cloud computing, big data and Internet of Things have played a significant role. At the worst of the epidemic, the 5G high-definition webcast allowed people to witness the "China speed" built by Wuhan Vulcan Mountain and Thunder God Mountain hospital; In the front line of epidemic prevention and control, 5G intelligent robots, 5G unmanned epidemic prevention vehicles, 5G thermal imaging temperature measurement systems and other applications have played an irreplaceable role; 5G also makes it possible to popularize online office and online education on a large scale.
Zhao Juntao, president of Ericsson China, also said that the company is exploring the industrial application of 5G with global operators, more than 40 universities and scientific research institutions and more than 30 industry partners. At present, more than 50 application reference cases of Industry 4.0 have been completed, and more than 20 test network deployment and verification tests have been completed, covering a wide range of fields such as smart factories, mineral mining and smart ports.
At the same time, according to the monitoring of China ICT Institute, as of May this year, there have been 484 actual scenarios of 5G applications in China. From the perspective of sub-industries, telemedicine, online education, smart cities, car networking and industrial Internet have achieved the first landing of 5G applications. According to the forecast of the Global Association for Mobile Communications, the global 1/5 connection will be based on the 5G network in the next five years. According to the information released by China ICT Institute, in 2020-2025, the commercialization of 5G in China is expected to indirectly boost the economic aggregate by about 24.8 trillion yuan.
The new action indicates a new trend.
As the largest 5G operator in China and even the world, China Mobile's every move will attract much attention. Last month, it was reported by the media that China Mobile will take 5G autonomous driving as the core, supported by 5G cellular network, high-precision positioning network and vehicle-road collaborative network to promote the rapid landing of autonomous driving.
The company also released the world's largest "5G+ high-precision positioning" system, providing sub-meter, centimeter and millimeter high-precision positioning services for vehicle management, vehicle-road coordination, automatic driving and automatic parking in real time through the 5G network. In terms of the construction of vehicle-road collaborative demonstration zone, China Mobile said that it has completed several vehicle-road collaborative projects such as Wuxi Vehicle Networking Experimental Zone, Wuhan Economic Development Zone Demonstration Zone and Suzhou High-speed Railway New Town Experimental Zone, and has taken the lead in building the largest vehicle-road collaborative network in China.
It is reported that at present, China Mobile has built more than 60 intelligent networking and autopilot demonstration projects in China, and among the projects under construction, only China Mobile has supported nearly 100.

Undoubtedly, in the whole market environment, the new ecological prospect of the network spawned by 5G technology has been optimistic by many parties. Although there is no "subversive" core application in the world at present, there will be phenomenal products similar to Alipay in the future.
