What’s the difference between 5G and 6G?

As we know, 4G is the era of mobile Internet and 5G is the era of Internet of Things. 5G has been widely known for its features of high speed, low latency and large connection, and has been gradually applied to various scenarios such as industry, telemedicine, autonomous driving, smart home and robot. The development of 5G makes mobile data and human life get a higher degree of adhesion. At the same time, it will revolutionize the working mode and lifestyle of various industries. With the maturity and application of 5G technology, we are thinking about what is 6G after 5G? What’s the difference between 5G and 6G?

What is 6G?

6 g is true everything connected, the unity of heaven and earth, 6 g network will be a ground wireless and satellite communications integration across the connection, by integrating satellite communications to 6 g mobile communication, achieve global seamless coverage, network signal can reach any a remote countryside, make deep in the mountains of remote medical treatment, patients can accept to let the children can accept the remote education.

In addition, with the joint support of the GLOBAL positioning System, telecommunications satellite system, earth image satellite system and 6G ground network, the full coverage of the ground and air network can also help humans predict the weather and quickly respond to natural disasters. This is the future of 6G. The data transmission rate of 6G May reach 50 times that of 5G, and the delay is reduced to one tenth of 5G, which is far superior to 5G in terms of peak rate, delay, traffic density, connection density, mobility, spectrum efficiency and positioning ability.

What’s the difference between 5G and 6G?

NeilMcRae, chief network architect of BT, looked forward to 6G communication. He believed that 6G will be “5G+ satellite network”, which integrates satellite network on the basis of 5G to achieve global coverage. Although there is no standard definition of 6G at present, it can be reached consensus that 6G will be the fusion of ground communication and satellite communication. The development of satellite communication technology is very important for the business of 6G, so how is the development of satellite communication enterprises at home and abroad? How soon will ground and satellite communications be integrated?

Now no longer is the national government as the leading aerospace industry, some excellent commercial space start-ups appeared successively in recent years, the market opportunity and challenge coexist, StarLink is expected to provide the service in this year began a preliminary, profit, financial support, cost control, innovation consciousness and iterative upgrade commercial thinking has become the key of the success of commercial space.

With the synchronization of the world, China will also usher in the important development period of low orbit satellite construction, and state-owned enterprises will participate in the construction of low orbit satellite as the main force. At present, the “national team” with the Aerospace Science and Industry hongyun, Xingyun project; Hongyan Constellation of aerospace science and technology, yinhe aerospace as a representative, has formed a preliminary subdivision industry around satellite Internet construction. Compared with private capital, state-owned enterprises have certain advantages in capital investment and talent reserve. Referring to the construction of the Beidou Navigation satellite System, the participation of the “national team” may enable China to deploy satellite Internet more quickly and efficiently, making up for the lack of cash flow in the early stage of satellite construction.

In my opinion, China’s “national team” + private enterprises to build satellite Internet model can fully mobilize national social resources, accelerate the improvement of the industrial chain, faster in the international competition to obtain a dominant position, in the future industry chain upstream components manufacturing, midstream terminal equipment and downstream operations are expected to benefit. In 2020, China will incorporate “satellite Internet” into new infrastructure, and experts estimate that by 2030, the total size of China’s satellite Internet market could reach 100 billion yuan.

Ground and satellite communications are integrated.

China academy of information and communication with the galactic space technology has carried out a series of Leo satellite constellation system test, test the signal system based on 5 g, break through the satellite communication system and the ground mobile communication system because of the difference signal system the problem of difficult to fusion, has realized the Leo satellite network and the ground 5 g network depth fusion, It is a key step to solve the problem of general technology of earth and earth network in China.

The series of technical tests rely on low-orbit broadband communication satellites, communication stations, satellite terminals and measurement and operation control systems independently developed by Yinhe Aerospace, and are verified by special testing equipment and instruments developed by THE China Academy of Information and Communication Technology. Represented by Leo broadband communications satellite constellation satellite Internet, because of full coverage, large bandwidth, hour delay, low cost advantages, not only is expected to be 5 g and 6 g era to realize global satellite communication network coverage solution, also is expected to become the aerospace, communications, the Internet industry the important trend of convergence.
