Recently, the Ministry of Industry and Information Technology issued commercial licenses for 5G (5th generation mobile communication network) to China Telecom, China Mobile, China Unicom and China Radio and Television, marking China”s official entry into the first year of 5G commercialization. Minister of Industry and Information Technology Miao Wei said that enterprises should be market- and business-oriented, actively promote 5G convergence applications and innovative development, focus on industrial Internet, Internet of Things, Telematics and other fields, empower more vertical industries with intelligence, and promote the digitalization, networking and intelligence process of all industries. China Telecom, China Mobile and China Unicom will each cover 5G networks in at least 40 cities this year, accelerating the construction of new smart cities and providing new development opportunities.
Where are the new opportunities for smart city construction?
Industry value is being reshaped
5G is not only an extension of 4G (4th generation mobile network), but also a huge breakthrough and innovation for the latter, with download speed significantly increased to 1.25GB/s. In 2005, Huawei conducted initial exploration of 5G technology. funding support. from 2016 to 2018, China focused on promoting 5G technology research and development.
With faster transmission speeds, ultra-low latency, lower power consumption and massive connectivity, 5G opens up a new era of Internet of Everything, spawning and driving the digital development process in various industries, bringing new players in transportation, energy, manufacturing, education, healthcare, community, consumption, leisure and entertainment, enabling the rapid evolution and even the subversion and reshaping of traditional business models, and creating a huge economic space.
New opportunities are emerging
In the construction of smart cities, transportation is an important part of the construction, which not only affects the image of the city, but also relates to the prospects of urban economic development. In the deployment of smart city transportation, 5G technology needs to be fully utilized. 5G technology can create a good environment for real-time information interaction between vehicles and roads, vehicles and vehicles, and on this basis, realize the effective transmission and sharing of driving paths and each other”s locations, which can effectively avoid traffic congestion and solve this common urban problem, and help improve the efficiency of traffic operation, provide convenience for people to travel and reduce traffic accidents. Provide convenience and reduce the occurrence of traffic accidents. At the same time, 5G technology can update and provide vehicle information in real time, reducing passenger waiting time; making intelligent traffic management possible, accurately classifying car models, reasonably arranging traffic routes based on actual traffic conditions, improving traffic efficiency and reducing the possibility of congestion.
In 2019, the country”s first 5G intelligent transportation demonstration application was unveiled in Chengdu, Sichuan. It not only achieves a major breakthrough and innovation in the previous traffic management model, but also explores the practice of “integration of heaven and earth” cooperative operation. The new model of “5G helicopter drone” can strengthen road control in the air, improve traffic efficiency and management as a whole, and promote the development of smart city traffic deployment in the direction of advanced and modernization, and the continuous improvement of traffic infrastructure, becoming an important feature of urban progress.
Smart grid is another typical deployment of 5G technology in smart cities. According to the White Paper on 5G-enabled Smart Grid Applications, 5G technology enables the updating of conventional operation modes and the creation of customized “industry-specific networks”. At the same time, 5G technology application makes the smart city grid present a high degree of integration of information flow and power flow, which is not only conducive to efficient detection of energy consumption, but also to improve the efficiency of energy transportation and use, in line with the principles of smart city construction and development, and is of great importance to the two-way interaction between the grid and users.
By installing a smart grid, the US city of Chattanooga was able to significantly reduce equipment outages and power outages by about 50% during severe storms. With the help of 5G technology, it is necessary to accelerate the deployment and construction of smart grids, which can significantly improve the quality of life of urban residents and promote healthy urban development.
The increasing standard of living of the people, the pursuit of smart home is getting stronger and stronger, and also puts forward new requirements for the construction of smart cities. The establishment and final realization of the smart home system cannot be achieved without a high-speed and stable network, which also needs to be supported by 5G technology to achieve high-speed information transmission and effective control of various facilities and components. Although the current 4G technology has reached a certain height and has information transmission and connection functions, there are still frequent delays during operation, and the information transmission speed can hardly meet the actual demand. Compared to 4G technology, 5G technology has the advantages of higher sensitivity, faster transmission speed and more stable network performance, which can not only meet the current requirements of smart city construction, but also provide a quality experience for smart community and even smart home users.
For example, based on 5G technology for intelligent security systems, in the event of theft, the information can be fed back to the user in the shortest possible time to reduce unnecessary losses. 5G technology transmission speed of up to 10GB / s, enough to complete the high-speed transmission of important information, not only to provide high-definition, real-time video information, but also accurate facial recognition. As the “cell” of the huge system of smart city, the social and economic value of smart home cannot be underestimated, providing a reliable technical guarantee to create a better living environment and promote the healthy and harmonious development of the city.
The application of intelligent lighting systems in smart cities is gaining more and more attention and importance. 5G technology combined with the Internet of Things can make intelligent lighting systems play a greater role. This kind of system can automatically dim the light according to the presence or absence of vehicles and pedestrians on the roadway, truly realizing intelligent management at the city level. Smart lighting systems help to save energy, in line with the current strategic direction of sustainable development, while also improving community safety, reducing the workload of personnel and equipment operating costs. San Diego, California, USA, has implemented a smart lighting system based on 5G technology, saving approximately $1.9 million annually compared to the cost of operating conventional street lighting equipment.
5G technology is still innovating at an accelerated pace. It is a technical tool for building smart cities and can bring considerable social and economic benefits. In the construction of smart cities, it is a common direction for the industry to explore how to realize the reasonable application of 5G technology according to local conditions and time, so that it can be most effective in smart transportation, smart grid, smart lighting, smart home, etc.
