5G Network Helps the Deep Development of Internet of Things
The Internet of Things provides an important platform for the integration and innovation of artificial intelligence, big data, cloud computing and other technologies, and is becoming another commanding height of industrial competition after the Internet. Accelerated iteration and evolution of 5G, edge computing, artificial intelligence, big data, etc. It also promoted the window period of large-scale development of the Internet of Things and the opportunity period of a new round of ecological layout.
"80% of 5G applications in the future will be the Internet of Things. At present, the pace of 5G commercialization in China has accelerated, and more than one million narrowband IoT base stations have been commercialized, with the number of connections reaching 65.438+0.5 billion, building the world's largest narrowband IoT network. " Wang Zhijun, Vice Minister of the Ministry of Industry and Information Technology, said at the 20 19 Wuxi Summit of the World Internet of Things.
The arrival of 5G has greatly promoted the development of Internet of Things technology. With 5G as the origin, with its further commercialization, the IOT world will be greatly enriched. Relying on the characteristics of large bandwidth, low delay, high reliability and millions of connections per square kilometer, 5G network can effectively support the real-time massive connection of intelligent devices such as car networking, intelligent manufacturing and telemedicine, which is also an important node for the next development of the Internet of Things.
New applications are emerging one after another.
The Internet of Things has a wide range of uses, which not only contributes to the development of the industry, but also is closely related to daily life. 20 19 World Internet of Things Expo shows many popular applications. China Telecom's "5G+8K" ultra-high definition video live broadcast, China Mobile's "5G+ Intelligent Manufacturing" simulation factory, and China Unicom's 5G telemedicine emergency system attracted a large number of viewers to stop and experience. The "WIoT-PARK" (Internet of Things Park) immersive interactive experience exhibition area debuted, bringing a number of experience exhibitions such as VR watching Wuxi, 5G live broadcast, VR bungee jumping, Rosen Smart Supermarket, 5G Future Restaurant, and Great Health Physical Examination Center.
5G+ car networking
By connecting cars with cars, cars with pedestrians, cars with infrastructure, cars with clouds, cars with traffic command centers, car networking can inform drivers of real-time traffic conditions around their destinations more accurately and timely, and effectively improve travel efficiency.
At the entrance of Hall B of the Expo Center, there are many people waiting in line to experience bus networking. After a 20-minute drive, the experiencer felt the auxiliary driving functions such as road congestion warning, sidewalk deceleration, pedestrian blind zone detection, intersection collision prediction and so on. In addition, automatic distribution logistics vehicles, automatic sweepers and 5G remote driving in the 5G driverless experience area also attracted everyone to stop and watch.
5G+ medical treatment
The 5G telemedicine system and 5G ambulance model displayed by China Mobile made the participants feel the changes of "seeing a doctor" and "treating a disease" more intuitively. Remote real-time dynamic ECG system, emergency management system of chest pain center, hand-held B-ultrasound and other IoT medical equipment crowded the booth. Through the background of hospital work, monitoring and treatment equipment, and user APP, doctors can break the geographical restrictions, obtain the patient's ECG, blood pressure, blood oxygen, pulse and other information in real time, and issue a diagnosis and treatment plan in time. In May this year, Jiangsu Mobile signed a strategic cooperation agreement with Jiangsu Provincial Hospital and Jiangsu Provincial Hospital of Traditional Chinese Medicine, and the 5G ambulance was one of the key points of cooperation. The 5G ambulance can transmit the patient's signs, condition assessment images and other information to the hospital at millisecond speed, and interact with high-definition audio and video synchronously, which can effectively shorten the emergency response time of the hospital and strive for greater vitality for patients.
5G+ industry
In ZTE's exhibition area, its 5G+ industrial park scheme uses the pan-5G network covering the park to realize the ubiquitous connection of production equipment, instruments, cameras, drones and robots in the park, and unified management through the Internet of Things platform; At the same time, the abnormal situation in the park is controlled in real time through the work order system, and the visual comprehensive management and control of the industrial park is realized.
In the 5G+ industrial machine vision scheme, the high-definition video signal is collected by the high-definition camera on the industrial site, transmitted to the edge side for machine vision analysis through the 5G network, and the edge side is controlled in MEC in real time. Machine vision scheme has a large number of applications in the industrial field. For example, in the process of wheel hub quenching, the video of wheel hub quenching is collected by high-definition camera, and the color change of wheel hub is analyzed by machine vision to judge whether the temperature meets the quenching quality requirements, so as to realize the closed-loop control process of machine vision detection, finished product quality judgment and industrial equipment adjustment.
5G+ education
China Unicom can provide a complete set of solutions for network, platform, content and terminal by using 5G+VR. Combining the key technologies of the network layer, the distributed deployment and multi-scene access capability of the platform layer, the all-discipline high-quality resources of the content layer and the multi-terminal access of the terminal layer, China Unicom can create a highly developed, interactive and immersive three-dimensional learning environment for learners, and truly realize the teaching requirements of full-time, full-space and full audience advocated by the Ministry of Education.
* * * Seeking a good strategy for the development of the Internet of Things
The Internet of Things has played a significant role in supporting and radiating national strategies such as network power, digital China, smart society and digital economy, and has become a powerful driving force for economic development. However, with the advent of the Internet of Everything era, security issues have also become prominent.
The ubiquitous connection of the Internet of Things has broken the traditional network boundary, and the application of new technologies such as 5G and artificial intelligence has aggravated the security risks of the Internet of Things. At present, the equipment foundation of the Internet of Things is huge, but the security protection is generally fragile. The Internet of Things is frequently attacked, which leads to serious consequences such as devices being controlled, users' privacy being leaked and data being stolen, and even affects the normal operation of the basic communication network. Ensuring security has become a prerequisite for the healthy development of the Internet of Things industry.
At the 20 19 World Internet of Things Expo Information Security Summit Forum, many experts discussed the practice and development of Internet of Things security in the 5G era. Experts pointed out that the current Internet of Things still needs to face three major challenges. First of all, in terms of independent innovation, although the core technology has developed, it has not changed fundamentally under the control of people. There is still a long way to go and difficulties need to be overcome. Secondly, in terms of security and controllability, although the technology of foreign Internet of Things products is advanced, the phenomenon of preset back doors is frequent, and security precautions need to be constantly mastered. Finally, in terms of security ecology, although the domestic Internet of Things ecology is improving day by day, some key elements are still in the hands of the United States and the West, and the pain of healing is still imminent.
Huang Dianzhong, deputy director of the Expert Committee of China Information Security Evaluation Center, said: "The Internet of Things carries the strategy of rejuvenating the country through science and technology and the dream of strengthening the country through network. We need to realize the upgrading and transformation of independent development, active security and ecosystem construction; Realize the transformation from "block layout" to "ecosystem"; Realize the transformation from "controlled by people" to "independent development"; Realize the transition from' passive security' to' active security'. "
How did the Internet of Things change the world? Wang Zhijun said that China is carrying out a new round of Internet of Things development layout, and will strive to break through key core technologies such as core chips, intelligent sensors, intelligent transmission, intelligent information processing and operating systems, so as to fundamentally enhance the core competitiveness of the industry. In addition, application first, China will enhance industrial competitiveness through large-scale development, promote industrial landing through demonstration of iconic application scenarios, focus on supporting accelerated deployment in the fields of vehicle networking and industrial Internet, strengthen the docking of production and demand, and achieve large-scale development.
Operators, as builders of a new generation of information infrastructure, will shoulder new missions and create new values in the era of "intelligent everything". Li Guohua, general manager of China Unicom, said that, first of all, operators will widely deploy 5G infrastructure, build a wide-coverage high-performance network and realize the whole network; Secondly, operators will be enablers of vertical industries, and cooperation with different vertical fields will be deeper, providing inclusive services for enterprises and consumers; Thirdly, in order to realize resource optimization and value reconstruction, operators will design and practice new business models, seek win-win cooperation and become explorers of business models; Finally, "integration" will be the keynote of the era of all things, and operators will play more roles as drivers of ecological construction and build an ecological circle with all parties in the industry to achieve * * * development.
