First, the performance is stronger.
The rate of 5G is higher, and the theoretical peak rate can reach 10-20G per second, which is 20 times that of 4G. (Under the current experience, it takes about 10 second to download an ultra-high definition movie with 1G on the 4G network, and less than 10 second on the 5G network. ) 5G will also bring a very low delay experience, and the wireless terminal delay will be shortened from tens of milliseconds of 4G to milliseconds (the intelligent control response distance of unmanned braking can be shortened from 1.4 m in 4G network to about 3 cm in 5G network). At the same time, the number of 5G connections has increased, and the connection density has reached per square kilometer 1 household, which is about ten times that of 4G. Everything from street lamps to water meters can be connected to the 5G network, which provides a solid foundation for realizing global full connection and digital upgrade.
Second, there are many scenes.
5G not only considers the connection between people, but also considers the connection between people and things, things and things, which really pushes the world into the era of Internet of Everything. There are three typical application scenarios of 5G, namely enhanced mobile broadband scenarios (such as 4K HD live broadcast, virtual reality VR/ augmented reality AR, etc.). ), massive connection scenarios (such as smart cities, environmental monitoring, etc. ) and low latency and high reliability scenarios (such as industrial control, telemedicine, car networking, etc.). In the past, communication needed to go through the base station. That is, the communication between two mobile phones needs to send the signal to the base station first, and then the base station forwards it. In the future, 5G communication may realize transmission between devices.
Third, a brand-new ecology.
The biggest feature of the 5G era is the deep integration of the communication industry and all walks of life, from the past single communication field innovation to cross-domain collaborative innovation. What if 4G is? Road construction? , 5G is more like? Building a city? . By creating a cross-industry integrated ecology, 5G empowers all walks of life, enhances the digital level of the whole society, and becomes the basic driving factor and important infrastructure of a smart society. 5G changes society? The vision of.
