Many users will find that after the relevant Settings in the background of the wireless router, the use of a mobile phone for wireless network connection, but found that there are two WiFi signal names, one WiFi signal is a traditional 2.4G, and another name will be followed by a 5G logo, why there are two signals? This is because the wireless router supports 2.4&5.8GHz bands.
What does Wifi 5G mean?
The traditional wireless router only has a WiFi signal in the 2.4G band, and the dual-band router has a WiFi signal in the 5G band in addition to a WiFi signal in the 2.4G band. Since the vast majority of wireless routers work in the 2.4G frequency band, the interference between signals is relatively large, especially where there are more wireless WiFi devices, which is easy to affect the network speed.
The addition of 5G frequency band to dual-band routers can not only reduce the problem of mutual interference of wireless signals, but also significantly improve the rate.
Analysis of advantages and disadvantages of 2.4G and 5G WiFi:
2.4G WiFi advantages: the 2.4G signal frequency is low, the attenuation is small when propagating in the air or obstacles, and the propagation distance is longer;
Disadvantages of 2.4G WiFi: At present, most devices use 2.4G band, where there are more users, the interference is larger.
5G WiFi advantages: 5G signal bandwidth is wide, the wireless environment is relatively clean, less interference, the network speed is stable, and can support higher wireless rates.
Disadvantages of 5G WiFi: 5G signal frequency is high, the attenuation is large when propagating in the air or obstacles, and the coverage distance is generally smaller than the 2.4G signal.
5G WiFi requires device (mobile phone, laptop, tablet) support
5G WiFi can only be supported by dual-band routers! In addition to the need for wireless router support, 5G WiFi also needs to be supported by devices connected to the network, that is, old mobile phones, laptops, tablets do not support 5G WiFi network, even if you are a dual-band router can only search for 2.4G WiFi network. However, in recent years, new smartphones, laptops, and tablets can support dual-band WiFi, and can search for 2.4G and 5G WiFi at the same time.
So for users, which is better, 2.4G or 5G WiFi connection?
wifi signals are transmitted through radio waves, 2.4G and 5G are two different frequency bands, and WiFi signals are transmitted in such frequency bands. The 5G band has a higher frequency, carries more data, and currently has fewer applications and lower interference, so the effect is better, but the transmission distance is closer.
If you move around a large range, it is recommended to connect to ordinary 2.4G WiFi, mainly because 5G band WiFi signal coverage compared to 2.4G has no advantage. If you are near a dual-band router, it is undoubtedly recommended to use 5G WiFi, which is more stable on the signal and faster on the network speed, and 5G WiFi is generally preferred.
