The "China 5G Economic Seminar" held in 2019 once released a report on the "China 5G Economic Report 2020". The report stated that it is expected that by 2020, China's total 5G investment will reach 0.9 trillion yuan, and it will reach 1.5 in 2025. Trillion yuan. The concentrated and high investment in the 5G industry in the past five years will be the foundation and key to boosting China's 5G technology research and rapid promotion of the application of 5G technology in various industries.

　　The main reason why 5G can attract the country's attention is that as an information infrastructure, 5G network can greatly play a key investment role and is considered to be one of the important directions of my country's "new infrastructure". The contents of 5G, data center, artificial intelligence, and industrial Internet in the "new infrastructure" are closely related and mutually promote, and also represent the direction of information communication technology and industry.

　　In June 2019, the issuance of 5G commercial licenses sounded the clarion call for China's 5G commercialization. At this stage, the entire 5G industry chain is fully invested in 5G infrastructure construction.

　　According to statistics published by the three major operators, China Mobile has opened 74,000 5G base stations, and China Unicom has opened 64,000 5G base stations. According to the operator's further disclosure, China Mobile plans to reach 300,000 5G base stations by the end of 2020, and China Unicom and China Telecom will jointly build a total of 250,000 base stations. In total, my country is expected to build 600-65 million 5G base stations in 2020. The Ministry of Industry and Information Technology also stated that it will strive to achieve 5G network coverage in all prefecture-level cities across the country by the end of 2020.

　　Entering the first year of 5G, large-scale network construction is about to start, and 5G downstream applications are also accelerating. From the current exploration of various application scenarios around 5G in the industry, it can be seen that several core application scenarios of 5G in the next few years will include ultra-high-definition video, car networking, intelligent manufacturing, wireless medical care, etc. With the further improvement of 5G infrastructure construction and the phased exploration of applications in the "5G+ industry" of segmented industries, the overall upgrade of the 5G network environment is expected to drive multiple application markets into a new stage of development.

　　5G commercial, advance security into a new journey

　　The network technology advantages of 5G in terms of high throughput, low latency, and ultra-large-scale connections have made it also attract attention in the field of security video surveillance. 5G+AI+ video is considered to be the core technology to realize the perception of all things, the interconnection of all things, and the intelligence of all things. At the same time, it has become the anchor and accelerator of the digital and intelligent transformation of the industry, which brings new imagination to the security market.

　　With the arrival of this wave of 5G, relying on 5G high-throughput and low-latency network conditions, it can be estimated that the first to benefit from the security field will be mobile surveillance, wireless surveillance and other market segments. There are two main transmission methods for video surveillance systems, namely wired transmission and wireless transmission. With the vigorous advancement of a series of engineering projects such as Safe City, Smart City, and Xueliang Project, most of the current video surveillance systems are basically wired video surveillance established in cities, towns and villages. The opening of the application of 5G in the security field will greatly help the development of wireless monitoring, mobile monitoring and other systems, and promote such systems in urban emergency prevention and control, public security mobile investigation and control, high-speed traffic supervision, forest fire prevention, river monitoring, border and coastal defense Security and other scenarios realize more flexible and efficient applications.

　　At the same time, relying on 5G's high transmission rate, low latency, high broadband and other characteristics, 5G will also further promote the performance of mobile surveillance systems in intelligent applications. With the support load of 5G technology, more abundant and in-depth artificial intelligence applications will also be realized. Artificial intelligence algorithms such as face recognition, behavior recognition, license plate recognition, and target classification at the edge, ultra-high-definition video quality can capture more details of the screen, and the richness of detailed features will be more conducive to artificial intelligence recognition and analysis, thereby deriving more Diversified AI applications.

　　Secondly, based on the advantages of 5G ultra-high bandwidth, the ultra-high-definition video industry will also carry this wave of 5G technology into a new stage of development. The large-scale application of artificial intelligence puts forward higher requirements for the high-definition picture quality of video surveillance. However, originally limited by network bandwidth conditions, the industry's video surveillance is still dominated by 2 million pixels, and the video surveillance that can reach 4K pixels is still In a few. The launch of 5G has laid the foundation for the video industry to move towards a new milestone in 8K ultra-high-definition video. 5G has a good carrying capacity for 4K and even 8K ultra-high-definition video. Ultra-high-definition video surveillance will benefit from this wave of 5G commercial trends and usher in new development and advancement. The development of the ultra-high-definition video industry will also bring about the simultaneous development of core component industries such as 4K/8K codec chips, professional video processing chips, and optical lenses.

　　The breakthrough brought by 5G in low-latency network transmission performance can significantly advance the speed and effect of video surveillance picture return. It is understood that the theoretical peak of 5G technology can reach 10GBPS, that is, the download speed is 1.25GB/s, and it has the characteristics of millisecond low latency and ultra-high density links. Low latency means that the uplink and downlink speeds are faster, and the response time is greatly shortened to negligible. Such network advantages can solve the problem of ultra-high density mobile Internet links.

　　5G has brought about a new revolution in the network environment. Artificial intelligence has changed the way machine vision transforms from the physical world to the digital world. The fusion of these two technologies in the security field is currently forming a new combination of "5G+AI+security" , To promote the video surveillance industry to a new stage of ultra-high definition and AI intelligence. In the Internet of Things era that advocates the Internet of Everything, video surveillance, as a key visual perception component, is being re-given with new application values ??and missions. It is moving into the new application unit of the video Internet of Things, in smart cities, urban brains, and machine vision. And many other application fields glow and heat.

　　"5G+Video" Opens Diversified Scenes

　　Around 5G innovative applications, the construction, production, research, and user units composed of operators, equipment vendors, and G-end/B-end users are currently actively exploring. From the perspective of the application of the video Internet of Things, the arrival of 5G is promoting the opening of innovative application models for multiple application scenarios such as 5G + smart police and 5G + smart cities.

　　The development and promotion brought by 5G to mobile surveillance was immediately reflected in the law enforcement mode of smart police. In January 2020, the Tianhe District Bureau of Guangzhou Public Security Bureau took the lead in launching the first 5G smart police platform in China. With the help of Telecom Tianyi Cloud 5G network, AI intelligent algorithms, big data applications and other technologies, it not only landed drones New police applications such as air patrol, mobile patrol law enforcement, AR recognition, 4K video surveillance, and so on, have realized the three-dimensional patrol of "5G + intelligent law enforcement terminal + high-definition video real-time return + AI intelligent identification".

　　With the 5G network's high-speed, large-bandwidth, and low-latency characteristics, the "Sky Eye" system, urban low-altitude patrol drones, mobile inspection vehicles and other equipment can transmit high-definition video shots back to the 5G smart police platform in real time. Through big data and AI intelligent recognition, the abnormal situation is automatically judged and fed back to the command center. The command center responds quickly according to the video situation. If you are looking for criminal suspects in the crowd, “Sky Eye” and other devices will transmit the collected high-definition video to the smart police platform via 5G. AI intelligent recognition will automatically analyze and identify the suspect in the crowd, and feed it back to the public security system command center , The command center quickly organizes and dispatches additional police forces to arrest in real time based on real-time video. Not only that, with the support of 5G smart policing, the public security department can also carry out high-altitude and ground three-dimensional patrols during major events with intensive crowds and accidents to create an all-round integrated patrol of the air and ground in the core area of the city.

　　In addition, in the smart city scenario, 5G empowered application fields can be described as all aspects. Datang Network President Yang Yong once said that 5G provides a more stable and efficient information transmission channel. The network system with information transmission as the core will evolve into a digital infrastructure integrating perception, transmission, connection, calculation, processing, and exchange. High-speed ubiquitous, intelligent and agile, intensive and efficient, safe and reliable. After 5G is commercialized, the Internet of Things will be stronger than the Internet of People. It is an important basic common capability of 5G and an important carrier for the construction of smart cities.

　　In the current progress of 5G applications in many cities, mobile 5G intelligent inspection robots, 5G drones and other mobile intelligent terminal equipment can help the police on duty complete basic, repetitive, and dangerous security work; based on mobile 5G transit Networking technology, through a variety of sensing devices such as smoke, temperature, air, hydraulics, etc., to achieve smart firefighting functions such as warning emotions and alarms; 5G technology empowerment also brings 5G-AR dressing mirrors, 5G Various consumer experiences such as special product traceability, VR experience, 5G immersive film and television, etc. explain the significance of C-end market technology changing lives.

　　As a key infrastructure of a smart city, 5G extends the connection between people to the Internet of Everything. With the large-scale construction of 5G network base stations and the accelerated popularization of 5G terminals, more business models in the application scenarios spawned by 5G will continue to emerge. The implementation of smart scenarios and the integration with various industries will enter a comprehensive acceleration. At this stage, smart city construction operators are expected to usher in new opportunities for development.

　　Technical research direction and market expectations for 5G commercial use

　　The opening of 5G commercialization has created new business opportunities in many application fields. From an objective point of view, there are still many problems that need to be resolved in terms of the current 5G infrastructure construction situation to support large-scale commercial use.

　　The first thing to overcome is the technical difficulty. At present, a series of brand-new technologies such as millimeter wave, small cell, massive MIMO, and beamforming provide technical support for 5G commercial deployment. High-frequency millimeter waves are more difficult to cross obstacles, and there is no signal. This problem can be solved by using thousands of low-power small cell networks. Massive MIMO can support hundreds of ports, and the network capacity is up to 22 times the current capacity. Coupled with the wave speed shaping technology, it can process more data streams more efficiently and transmit information faster. In fact, everything about 5G is still being studied, it may include other new technologies, and there are still many technical difficulties that need to be broken through.

　　Network coverage is another major problem in 5G deployment. After all, the higher the frequency, the smaller the coverage capacity of the base station. To achieve ubiquitous network connection, it seems that a million base stations are not enough. In order to truly achieve full 5G coverage in the future, the construction density of 5G base stations must first be increased. In this process, the cost pressures faced by operators and the investment in installation and construction are not short-term problems, and they still need to be promoted gradually.

　　Technical research and network coverage are on the one hand, and from a commercial point of view, 5G is a new frontier technology. At this stage, all applications are under preliminary exploration. Early adopters of the market cannot guarantee the sustainable development of 5G in the industry. , The key is to find a real application scenario and build a mutually beneficial and win-win business model around the scenario.　Of course, as one of the seven major directions of China's new infrastructure, the future market potential of 5G cannot be underestimated. With the gradual construction and popularization of 5G, it will work with artificial intelligence as the basic underlying technology to promote the rapid development of the AIOT market. For the future market outlook, smart security, smart city and other multi-application fields are also expounding expectations with active practical exploration.
