What is the concept of 6G network

6G, the sixth-generation mobile communication standard, is also known as the sixth-generation mobile communication technology. The main promotion is the development of the Internet of Things. As of November 2019, 6G is still in the development stage. The transmission capacity of 6G may be 100 times higher than that of 5G, and the network delay may also drop from milliseconds to microseconds.

Basic Concept

6G, the sixth-generation mobile communication standard, is a conceptual wireless network mobile communication technology, also known as the sixth-generation mobile communication technology. The main promotion is the development of the Internet.

The 6G network will be a fully connected world that integrates terrestrial wireless and satellite communications. By integrating satellite communications into 6G mobile communications, seamless global coverage is achieved, and network signals can reach any remote village, allowing patients in the deep mountainous areas to receive telemedicine and children to receive remote education.

In addition, with the joint support of global satellite positioning system, telecommunication satellite system, earth image satellite system and 6G ground network, the ground-to-air full coverage network can also help mankind predict the weather and quickly respond to natural disasters. This is the future of 6G. 6G communication technology is no longer a simple breakthrough in network capacity and transmission rate. It is more about narrowing the digital divide and realizing the “ultimate goal” of the Internet of Everything. This is the meaning 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. It is far superior in terms of peak rate, delay, traffic density, connection density, mobility, spectrum efficiency, and positioning capability. 5G.

Key technical indicators

Several key indicators to measure 6G technology:

  1. The peak transmission speed reaches 100Gbps-1Tbps, while 5G is only 10Gpbs;
  2. The indoor positioning accuracy is up to 10 cm, and the outdoor is 1 meter, which is 10 times higher than that of 5G;
  3. The communication delay is 0.1 millisecond, which is one-tenth of 5G;
  4. The probability of interruption is less than one in a million, with ultra-high reliability;
  5. The density of connected equipment reaches more than one hundred per cubic meter, with ultra-high density;
  6. Using terahertz (THz) frequency band communication, the network capacity is greatly increased.

Facing technical difficulties

  1. The immature terahertz communication technology poses technical challenges to integrated electronics and new materials.
  2. Technical difficulties in data collection to consumption.

Industry View

The development of 5G and 6G is parallel, but the large-scale use of 6G is still far away. In response, Yu Chengdong replied: “6G is in development, it is estimated that it will take another 10 years, and technology research and standard research are also being done, and it has not yet reached the commercial stage.

“The speed of 6G network will be 100 times faster than that of 5G, almost reaching 1TB per second. This means that downloading a movie can be completed within 1 second, and the control of unmanned driving and drones will be very comfortable. Users even feel There is no time delay.” said Wu Qihui, executive deputy dean of the School of Electronic Information Engineering, Nanjing University of Aeronautics and Astronautics.

“Academic circles now have different views on the definition of 6G. 5G is mainly for the preliminary infrastructure construction for Industry 4.0, and the specific application of 6G is still in the exploratory stage.” Chairman of the Communication Branch of the Chinese Institute of Electronics, Nanjing University of Posts and Telecommunications Internet of Things The dean of the college, Zhu Hongbo, said that some experts believe that in the future, 6G will be used in scenarios such as space communication, intelligent interaction, tactile Internet, emotional and tactile communication, multi-sensory mixed reality, collaboration between machines, and fully automated transportation.
