What are the application scenarios of 6G network in the future?

With the rapid penetration of 5G applications, continuous breakthroughs in science and technology, and the deep integration of DICT, 6G will fully support the digitalization of the world on the basis of 5G, that is, a digital twin virtual world is generated based on the physical world. People and things, things and things will be able to transmit information and intelligence through the digital world.

Looking back at the entire development history of mobile communications, the update rhythm of the "decade generation" covers all aspects of key technology research, standardization, industrialization, and commercial application promotion. Each generation of mobile communications technology tries to solve the problems faced by industry development and applications at that time. Problems, pushing the development of communication technology to a new height. The first 1G provided a solution for mobile voice communication, but the cost was high and the experience was poor; the latter 2G solved these problems well and realized the global popularization of mobile voice applications; 3G began to try data communication, although it was not very successful, but cultivated The application ecology has laid a good foundation for 4G to realize the rapid prosperity of the mobile Internet; 4G began to explore the application of the Internet of Things, while 5G hopes to realize the interconnection of everything. With the rapid penetration of 5G applications, continuous breakthroughs in science and technology, and the deep integration of DICT, 6G will fully support the digitalization of the world on the basis of 5G, that is, a digital twin virtual world is generated based on the physical world. People and things, things and things will be able to transmit information and intelligence through the digital world. The twin digital world is an image of the physical world, helping mankind to further improve the quality of life, increase production efficiency, and realize the vision of "6G reshaping the world". The combination of 5G, cloud computing, big data, and artificial intelligence will surely accelerate the entire society's move towards digitalization. So what is the next stage of digitalization? This article considers it to be a digital twin. In the future and even after 2030, the entire society will not only have a physical world, but also a digital world. The digital world is composed of digital mirror images of the physical world. Based on the digital world, it can simulate the operating state of the physical world and predict the development trend of the physical world. Based on these predictions, some preventive measures are formed to intervene in the operation of the physical world in advance, thereby changing the future. Digital twins were first used in the predictive maintenance of aircraft engines. If the aircraft's engine fails during flight, the result will be catastrophic, which will be unbearable for passengers and airlines. Therefore, aircraft engine manufacturers use digital twin technology to predict the operating conditions and possible failures of the entire aircraft engine, and perform maintenance in advance to ensure that the aircraft can fly freely without failure. I believe that this concept will gradually penetrate into all walks of life and every corner of society, thus forming a world of digital twins.

In the world of digital twins, the application of artificial intelligence technology will be very extensive. Artificial intelligence may be the hottest technology so far. It is hoped that the vision of ubiquitous development of wisdom can be realized after 2030, so that the application of artificial intelligence can be ubiquitous. At present, the social development vision of "digital twins and ubiquitous wisdom" has basically become the consensus of the industry. Under such a vision of social development, many new application scenarios will emerge, such as human digital twins, holographic interaction, synesthetic interconnection, and intelligent interaction. The first new application scenario is the human digital twin. By wearing or implanting sensors, various information of the human body is collected in depth, and based on the set model, a digital human body is constructed, which is called a digital human. Digital humans can simulate and simulate the local organs of the human body, the circulatory system of the body, etc., and then can predict the possible pathological changes of the human body, and perform simulation verification on the intervention methods, confirm that it can achieve the expected effect, and then intervene. Means are applied to the physical body to avoid the occurrence of diseases (such as cerebral infarction, myocardial infarction, etc.), and to achieve the highest medical realm of "preventing disease". In this way, the quality of human life and the quality of life can be greatly improved, and the problem of difficult medical treatment facing today's society can be solved. Of course, there are many things that can be done based on these body data, such as organ research, precision medicine, virus cultivation, and surgical assistance, etc., which will play a very important auxiliary role in improving the quality of human life. The second application scenario is synesthesia. The existing communication system can realize the transmission and interaction of vision and hearing, and in the future, people hope to transmit more senses, such as touch, smell, taste, etc., and even human emotions can be transmitted and interacted to realize the interconnection of synaesthesia . With synesthetic interconnection, collaboration between machines and machines, virtual social interaction, etc. are no longer a dream. We can pass hugs, or through synesthetic interconnection between coaches and athletes, improve the efficiency and effectiveness of skill learning. It even brings revolutionary changes. The third application scenario is super transportation. The future of transportation can be an integrated air, space and ground transportation. There are flying cars, unmanned delivery machines, and water vehicles. People can customize their travel methods according to the travel path, traffic conditions, destination, etc. , To maximize the needs of travel. To this end, the network must support more new capabilities, including connection capabilities that require high precision positioning, reliability, and security. The fourth application scenario is holographic interaction. Holography will completely change the form of communication and interaction, realize the upgrade of immersive experience, and bring about a revolution in the way of life, entertainment and work. Perhaps in future meetings, the speaker will be a holographic projection, and the audience may also be listening one by one holographic projection. The fifth application scenario is intelligent interaction. On the one hand, the form of interaction will become intelligent, especially human-computer interaction, which will be more contextualized and personalized, especially in terms of emotional escort for the disabled, intellectually disabled, patients, children and the elderly, which will bring deeper A level of humanistic care experience; on the other hand, intelligence, as a condensing of skills and experience, can directly interact between people, people and machines, and machines and machines, greatly improving the efficiency of learning and the efficiency of collaboration. From the scenarios mentioned above, it can be seen that the future business and applications will undergo very big changes, showing many new characteristics: First, the demand will become more diversified and fragmented, and the dynamic range of network capacity requirements It will be larger, including speed, delay, reliability, etc.; the second is the three-dimensional coverage, which not only considers the ground coverage, but also needs to consider the three-dimensional coverage, so satellites need to be considered as a supplementary coverage method; the third is interaction The form and interactive content will be more diversified, no longer the simple human-machine interface or simple communication content; the fourth is the openness and customization of the business, and the pursuit of personalization will enable humans to achieve self-liberation and self-worth An important form of performance, personalized service customization will bring more business models to the industry. Open services enable anyone to become a service provider, not just passively accepting operators and the Internet Service provider services; the fifth is the deep integration of communication, perception, computing, AI, and security. The future communication network will no longer only provide communication functions, but include computing capabilities, AI capabilities, security capabilities, and perception A comprehensive capability system including capabilities, thereby expanding the application space of the entire 6G network.
