Top 3 6G Network Development Plans and Application Scenarios –
Over the past couple of years, there has been a steady development of 5G. However, it looks like the industry won’t wait for 5G to mature before they start discussing 6G. Currently, industry practitioners are paying attention to 6G commercialization, exploration and discussion. As early as November 2019, the Chinese Ministry of Science and Technology launched the research and development of 6G technology. So far there have been a number of 6G seminars in different parts of the world. At present, China already has its 6G development plans and possible application scenarios. A recent special 5G / 6G meeting of industry insiders in China revealed the country’s three main development plans for the 6G network.
- One is to conduct extensive research on 6G application scenarios. This research will be based on existing 5G as well as technological evolution and economic and social development trends. The research will focus on proposals for 6G vision requirements and application scenarios.
- The second is to focus on promoting key technological breakthroughs in innovation.. Focus on potential 6G technologies such as terahertz communication, integration of communication and perception, and integration of communication and artificial intelligence. Actively plan, deploy and build a solid foundation, and strive for major breakthroughs in key technology areas.
- The third is to actively promote international exchanges and cooperation..
In addition, there was the presentation of a white paper titled “6G global vision and potential key technologies”. Now let’s look at the business application scenarios for 6G
Main business application scenarios for 6G
All The vision of 6G is “Smart Connection of Everything Digital”. In the future, 6G services will feature new development trends such as immersion, intelligence and globalization. It will also focus on training Immersive cloud XR (extended reality), holographic communication, sensory interconnection, intelligent interaction, communication perception, inclusive intelligence, digital twins and global coverage of the main business applications.
Specifically, immersive business applications such as cloud-based XR, holographic communication, sensory interconnection and intelligent interaction will provide users with a more immersive and extreme experience. It will also meet the interaction needs of humans on multiple sensory, emotional and conscious levels. In addition, this application will be popular in the entertainment industry, the healthcare industry and other digital transformation industries.
Smart business applications such as communication perception, inclusive intelligence and digital twins, using new capabilities such as perception and intelligence, will not only improve the performance of 6G communication systems, but also contribute also to complete the digitalization of the physical world and promote humans to enter the world of virtualized digital twins.
With the help of 6G, global business coverage will be seamless. With 6G, there will be a integrated global air-space-ground network. This means that there will be no blind spots for mobile communications coverage on land. The 6G business will provide more universal service capabilities and contribute to the sustainable development of humanity.
Top potential key technologies
In order to meet the above commercial applications, there are also potential key technology directions for 6G. One of the potential technologies is new endogenous intelligent air interface and new network architecture. We will also have improved wireless air interface technology, new physical dimension wireless transmission technology, new spectrum utilization technology, integrated communication perception technology and other new wireless technologies. Other trends will be in distributed network architecture, computing capacity network, deterministic network, integrated satellite-ground network, endogenous network security, and other new network technologies.
Regarding the relationship between the development of 5G and 6G, there are proposals that 6G will move from the Internet of Things (IoT) to the intelligent connection of things. However, the basis for 6G will be 5G. The successful commercialization of 5G, especially its wide application in vertical industries, will lay a good foundation for the development of 6G.
Regarding the issue of 6G spectrum resources, 6G will expand to higher frequency bands and make efficient use of low, medium and high full spectrum resources. Among them, the low frequency spectrum will remain a strategic resource for the development of 6G. Millimeter waves will play a bigger role in the 6G era, and higher frequency bands such as terahertz will focus on meeting the short range and high capacity requirements of specific scenarios.
Regarding the issue of the evolution of 6G intelligence, endogenous intelligence will become an important feature of 6G. The deep integration of artificial intelligence and communication technologies will trigger global innovation in networked information technologies.
In terms of the relationship of 6G with satellite networks, non-terrestrial communications and cellular networks, the 6G network will remain be based on terrestrial cellular networks. Satellites, drones, aerial platforms and other non-ground communications will be integrated into the network.
Advancement of the development of 6G in different regions
In China, the Ministry of Industry and Information Technology revealed in 2018 that it had started studying 6G technology. In November 2019, the Ministry of Industry and Information Technology and the Ministry of Science and Technology launched the research and development of 6G mobile communication technology. This means that in China, 6G research and development is officially enabled.
United States and Japan
The United States and Japan have announced a joint investment of $ 4.5 billion in the development of 6G. The United States will provide $ 2.5 billion while Japan will provide $ 2 billion. In addition, in order to further catch up with China’s development, the United States and Japan have also recruited Australia to cooperate and prepare to lay submarine communication cables in the Pacific.
The South Korean government plans to invest a total of 200 billion won ($ 169 million) from 2021 to 2026. This fund will launch an unstandardized 6G mobile service pilot project in 2026. 6G services are expected to be commercially available between 2028 and 2030. According to reports, its 6G pilots include immersive digital medical content, autonomous vehicles, smart cities and smart factories.
The German government plans to provide up to 700 million euros ($ 833 million) for research into 6G technology by 2025.
The development of 6G is underway. Judging by the pace of the countries so far, China is clearly ahead again. The total number of global 6G communication network technology applications is 38,000, and China accounts for one-third of the share. This means the country owns 35% and already owns 13,449 6G patents.
