The development of mobile communication technology seems to be somewhat overwhelming. 3G has not yet passed, 4G is on the rise, and 5G will come to an end. In the past year, the Ministry of Industry and Information Technology officially launched the 5G technology research and development test on the 7th. This means that China's 5G development has entered a critical stage of technology research and development and standard development. The Ministry of Industry and Information Technology also said that China will launch 5G commercial in 2020. In the end, what is 5G, how fast is it? 5G, popular speaking, is the fifth generation of mobile communication technology, but unlike 4G, 3G, 2G, 5G is not an independent, new wireless access technology, but for existing wireless access technologies (including 2G, 3G) , 4G and WiFi) technology evolution, and some new integrated solutions for complementary wireless access technology integration solutions. For our average users, the most intuitive experience brought by 5G will be the tremendous increase in network speed and the smarter and more convenient life. Nowadays, 4G networks are becoming more and more popular, and there are Tianyi 4G+, and the peak network speed is up to 300Mbps. It has become the first in China, but the video is still “local tyrantsâ€. In the 5G era, the eyes are closed and an ultra HD. The movie has been downloaded. Even in the future, we wake up in the morning and the lights and air conditioners in the bedroom can be turned on automatically. Get up in the morning and come to the bathroom. The face wash water is automatically adjusted to moderate temperature. The digital toothbrush records and uploads real-time data of teeth and mouth. I believe that with the 5G technology in the future, the technology and hardware involved in the above life will become a reality. With 5G network, WIFI will "dead"? Recently, the rumors that "5G is coming, WIFI will disappear overnight" are once again on the dust, but the actual situation is not the case. The coming and development of 5G will not only make the free WiFi die, but the two will be deeply integrated. Form a complementary relationship. It is not to replace 4G, WiFi, but to integrate 2G, 3G, 4G, WiFi and other networks into it, to bring users a more optimal experience. Because 5G does not have the difference of standard standards like 3G and 4G, 5G will be a unified network to provide users with smart, powerful and unified network applications. Users don't have to care about the network they are in. They don't need to connect to the WiFi network manually. The system will automatically connect to the best experience network according to the quality of the live network, and realize seamless handover. In a word: in the 5G era, WiFi is used in places where WiFi is used, and 5G is used when there is no WiFi. This is a reasonable imagination and a natural ecology.
