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 development. The transmission capacity of 6G may be 100 times higher than that of 5G, and the network delay may also be reduced 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 integrating terrestrial wireless and satellite communications. By integrating satellite communications into 6G mobile communications, seamless global coverage can be achieved, and network signals can reach any remote village, allowing patients in deep mountainous areas to receive telemedicine and children to receive distance education.
In addition, with the linkage support of the global satellite positioning system, the telecommunication satellite system, the earth image satellite system and the 6G ground network, the ground-air full coverage network can also help humans predict the weather and quickly respond to natural disasters. This is the 6G future. 6G communication technology is no longer a simple breakthrough in network capacity and transmission rate. It is more to narrow the digital divide and achieve 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 can be shortened to one tenth of 5G. It is far superior in terms of peak rate, delay, traffic density, connection density, mobility, spectral efficiency, and positioning capability. 5G.
Technical key 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 reaches 10 cm, and the outdoor positioning accuracy is 1 meter, which is 10 times higher than that of 5G;
3. The communication delay is 0.1 milliseconds, which is one tenth of 5G;
4. The interruption probability is less than one in a million, with ultra-high reliability;
5. The density of connected devices reaches over 100 per cubic meter, with ultra-high density;
6. Using terahertz (THz) frequency band communication, the network capacity is greatly improved.
Facing technical difficulties
1. The immature terahertz communication technology poses technical challenges to integrated electronics and new materials.
2. Technical difficulties in data collection from consumption to consumption.
Industry Views
The development of 5G and 6G is parallel, but the large-scale use of 6G is still far away. In this regard, Yu Chengdong responded: “6G is in the research and development, it is estimated that it will take 10 years, and it is currently doing technical research and standard research, but it has not yet reached the commercial stage.
“The speed of the 6G network will be 100 times faster than that of 5G, almost reaching 1TB per second, which means that downloading a movie can be completed within 1 second, and the control of unmanned vehicles and drones will be very comfortable, and users may even feel There will be no delay,” said Wu Qihui, executive deputy dean of the School of Electronic Information Engineering, Nanjing University of Aeronautics and Astronautics.
“Now the academic circles have different views on the definition of 6G. 5G is mainly for the preliminary infrastructure construction for Industry 4.0, and the specific application direction of 6G is still in the exploratory stage.” Chairman of the Communications Branch of the Chinese Institute of Electronics, Nanjing University of Posts and Telecommunications Internet of Things Zhu Hongbo, dean of the college, 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, inter-machine collaboration, and fully automatic transportation.
