There is a '5G' after the name of my WiFi, is it super fast?" With the full popularization of 5G, many citizens have questions. In this regard, China Mobile WiFi technology expert Zou Xing said that 5G of WiFi is the meaning of 5G Hertz, which represents the 5G frequency band, and mobile phone 5G is not the same thing.
There are two common WiFi working bands, 2.4G and 5G; 5G for mobile phones, which refers to the fifth-generation communication technology, is not the same thing as 5G for WiFi.

Router 5G WiFi
Why is there 2.4G and 5G after the WiFi name? Before the router only 2.4G a band of WiFi signal, very limited, many devices are working in the 2.4G band, and the interference between the signals is very large, the speed is not very fast. With the popularity of fiber broadband, many new routers are dual-band wireless routers that simultaneously transmit WiFi signals in both 2.4G and 5G bands.industrial router
2.4G WiFi signal has low frequency, long wavelength, small attenuation during propagation, easier to cross obstacles, and long propagation distance; However, 2.4G bandwidth is narrow, interference is more, easy to have congestion, 2.4G WiFi can reach 10M/S.5G industrial router
In contrast, 5G WiFi has a wide bandwidth, less interference, fast and stable speed, and the newly developed frequency band is like driving to the new city, with less road width and fast speed; However, its ability to penetrate the wall is poor, the transmission distance is close, and the 5G WiFi can reach a maximum of 60M/S.
Therefore, if it is closer to the router, then we should prioritize the use of 5G WiFi signals, so that the network speed will be faster. On the contrary, if you are far away from the router, then you will find that the 2.4G WiFi signal is better, and the 5G WiFi signal is almost impossible to connect.
Network characteristics
1, the peak rate needs to reach the standard of Gbit/s, in order to meet the high-definition video, virtual reality and other large data transmission.
2. The delay level of the air interface needs to be about 1ms to meet real-time applications such as automatic driving and telemedicine.
3, large network capacity, providing the connection capacity of hundreds of billions of devices to meet the Internet of Things communication.
4, the spectrum efficiency is more than 10 times higher than LTE.
5. Under continuous wide area coverage and high mobility, the user experience rate reaches 100Mbit/s.
6. The flow density and connection number density are greatly improved.
7, system coordination, intelligent level improvement, performance of multi-user, multi-point, multi-antenna, multi-intake collaborative networking, as well as flexible automatic adjustment between networks.
8. At present, most of the new mobile phones launched by mobile phone manufacturers support 5G network, first-tier cities have laid a large number of 5G network communications, and third - and fourth-tier cities and towns are still not popular.
Therefore, the true popularization of 5G network will take two or three years.wireless router
