5G has been commercially available for three years. After several years of development, China has built the world’s largest 5G network, with a total of more than 2.3 million 5G base stations, basically achieving full coverage. According to the latest data released by several major operators, the total number of 5G package users has reached 1.009 billion. With the continuous expansion of 5G applications, 5G has been integrated into all aspects of people’s lives. At present, it has achieved rapid development in transportation, medical treatment, education, administration and other aspects, truly empowering thousands of industries and helping to build a digital China and a powerful network.
Although 5G is developing rapidly, 6G has already been put on the agenda. Only by accelerating the research of 6G technology can it not be controlled by others. What is the difference between 6G as the sixth generation mobile communication technology?
6G uses the terahertz frequency band (between 1000GHz and 30THz), and its communication rate is 10-20 times faster than 5G. It has a wide application prospect, for example, it can replace the existing mobile network optical fiber and the huge amount of cables in the data center; It can be integrated with optical fiber network to achieve wide indoor and outdoor coverage; It can also carry satellites, unmanned aerial vehicles and other applications in inter-satellite communication and space-space integration and other scenarios to achieve space-space and sea-space integration communication. 6G will also participate in the construction of virtual world and real world, and create immersive VR communication and online shopping. With the characteristics of 6G’s ultra-high speed and ultra-low delay, holographic communication can be projected into real life through various technologies such as AR/VR. It is worth mentioning that in the 6G era, automatic driving will become possible.
As early as a few years ago, several major operators have begun to study the relevant technologies of 6G. China Mobile released the “China Mobile 6G Network Architecture Technology White Paper” this year, proposed the overall architecture of “three bodies, four layers and five sides”, and explored the quantum algorithm for the first time, which is conducive to solving the bottleneck of future 6G computing power. China Telecom is the only operator in China to deploy satellite communications. It will speed up the research of core technologies and accelerate the integration of heaven and earth access networking. China Unicom is in terms of computing power. At present, 50% of the world’s 6G patent applications come from China. We believe that 6G will enter our lives in the near future.
