Many users will find that after the wireless router background, using the mobile phone for wireless network connection, but found that there are two WiFi signal names, a WiFi signal is the traditional 2.4G, another name will have a 5G logo, why will there be two signals?This is because the wireless router supports the 2.4&5.8GHz frequency band.
What does a Wifi 5G network mean?
The traditional wireless router only has a 2.4G band WiFi signal, while the dual-frequency router has a WiFi signal of 2.4G band, and also has a 5G band WiFi signal. Because the vast number of wireless routers work in the 2.4G frequency band, the interference between signals is large, especially where wireless WiFi devices are more, easy to affect the network speed.
The addition of 5G frequency band to the dual-frequency router can not only well reduce the problem of mutual interference of wireless signals, but also can significantly improve the rate.
The Advantages and disadvantages analysis of 2.4G and 5G WIFI:
2.4G WiFi advantages: 2.4G signal frequency is low, less attenuation when propagation in air or obstacles, the propagation distance is farther;
2.4G WiFi disadvantages: At present, most devices use 2.4G frequency band, places with more users, greater interference.
5G WiFi advantages: 5G signal has a wide bandwidth, a relatively clean wireless environment, less interference, stable network speed, and can support a higher wireless rate.
5G WiFi disadvantages: high 5G signal frequency, large attenuation when propagating in air or obstacles, and the coverage distance is generally smaller than 2.4G signal.
5G WiFi requires device (mobile phone, laptop, tablet computer) support
5G WiFi is only supported by dual-frequency routers! 5G WiFi In order to need wireless router support, but also need to connect to the network device support, that is to say, old mobile phones, laptops, tablets do not support 5G WiFi network, even if you are a dual-frequency router can only search to 2.4G WiFi network. In recent years, however, new smartphones, laptops and tablets can support dual-frequency WiFi and search for both 2.4G and 5G WiFi.
So which is the better connection, the 2.4G or 5G WiFi connection, for users?
The wifi signal is transmitted through radio waves, and the 2.4G and 5G are two different frequency bands, within which the WiFi signal is transmitted. The 5G frequency band has a high frequency, carries more data, and is less used, with low interference, so the effect is better, but the transmission distance is close.
If you have a wide range, it is recommended to connect to a normal 2.4G WiFi, mainly because the 5G frequency band WiFi signal coverage has no advantage over 2.4G. If you are close to the dual-frequency router, it is undoubtedly recommended to use 5G WiFi, which is more stable in signal and faster in network speed. Generally speaking, the preferred 5G WiFi.
