At present, 792,000 5G base stations have been built in China, and the 5G network with independent networking mode has covered all prefecture-level cities, and the number of 5G terminal connections has reached 260 million.
Because China has an absolute advantage in the layout of 5G network, the application of 5G technology in the Internet of Vehicles, the Internet of Things and the industrial Internet has also developed rapidly.
The iterative update of communication technology can be said to be very fast, from the birth of the first generation of mobile communication to the emergence of 5G technology. In just a few decades, more intelligent communication devices have been derived and the rapid development of human communication field has been realized. At the same time, it has also changed all aspects of our lives.
0 1 first generation communication technology
The first generation communication technology is also called analog communication technology. Martin Cooper, an engineer born in Motorola, USA, first applied radio to mobile phones in 1976. At the end of 1978, the first mobile cellular telephone system among the world's advanced mobile telephone systems was successfully developed by Guobell Laboratory. Since then, humans can make simple voice calls.
02 second generation mobile communication technology 2G
The second generation mobile communication is mainly based on digital voice transmission technology, and the peak transmission rate can reach 100kbps. The unification of technical specifications and standards has been realized.
Features: 1G and 2G are "narrowband" technologies, which are mainly used for voice services. In the 2G era, data service (SMS short message service) was introduced.
3G, the third generation mobile communication technology
The third generation mobile communication is a new code division multiple access technology developed on the basis of code division multiple access. Compared with 2G communication technology, it improves the speed of voice and data transmission and solves the problem of wireless roaming.
The Fourth Generation Mobile Communication Technology 4G
The fourth generation mobile communication technology is a breakthrough improvement on 3G technology. The good combination of WLAN technology and 3G communication technology makes the image transmission faster and realizes the transmission of high-definition images. Its transmission speed can reach 100Mbps.
The Fifth Generation Mobile Communication Technology 5G
The fifth generation mobile communication technology 5G. It is the latest generation of cellular mobile communication technology and an upgrade after 4G, 3G and 2G systems. Widely used in intelligent scenes such as big data, Internet of Everything, artificial intelligence AI, AV/AR.
Just like this, with the strength of 5G, Huawei began to turn to the research and development and layout of 6G network technology. Through the cooperation of satellite and ground base station, all-round signal coverage without dead angle will be realized.
Xu Zhijun, the rotating director of Huawei, once said at the Huawei Global Analyst Conference that Huawei's 6G network will be put on the market around 2030, and Huawei will soon release a 6G white paper to tell all walks of life what 6G is.
Musk's star chain plan is to launch 12000 satellites and access the real broadband Internet through StarLink.
What Musk didn't expect was that
1. Last year, 1 1, the 6G satellite developed by the University of Electronic Science and Technology of China was successfully launched, which also enabled China to successfully explore terahertz space communication technology.
2. According to the famous V, "In July this year, Huawei will jointly launch two satellites with China Aerospace and China Mobile. If successful, this news will be announced at the Huawei Developers Conference in September. " It is also mentioned that this move is of epoch-making significance to China's core technologies such as network and exchange.
In the future, the transmission speed of 6G technology will be 100 times that of 5G, and the delay of network technology will be reduced to microsecond level. Higher, faster and better network transmission technology will be realized. Achieve seamless connection of global networks. We will completely surpass Musk's Star Chain plan and build our own 6G network service. 6G network technology is undoubtedly another "trump card" of Huawei. Not only that, Huawei also announced the charging standard for 5G patented technology.
