What is the concept of WIFI 2.4G and 5G?

Many users found that there are two WiFi signal names after setting the wireless router (Router) with mobile phone to connect to the wireless network. One WiFi signal is traditional 2.4G whereas the other one with a 5G logo. Why are there two signals? This is because the wireless router supports both 2.4GHz and 5.8GHz frequency bands.


What does Wifi 5G network mean?

Traditional wireless routers only have a 2.4G band WiFi signal. However, the dual-band routers have a 2.4G band WiFi signal and a 5G band WiFi signal. Since most of the wireless routers work in the 2.4G frequency band, the interference between signals is so large that the network speed will be easily be affected, especially when there are many wireless WiFi devices connected nearby.


The addition of a 5G frequency band to a dual-band router can not only reduce the problem of mutual interference between wireless signals but also significantly increase the speed.


Analysis of the advantages and disadvantages of 2.4G and 5G WiFi

2.4G WiFi advantages: 2.4G signal frequency is low, attenuation is smaller when propagating in the air or obstacles, and the propagation distance is longer;

2.4G WiFi Disadvantages: At present, most devices use 2.4G frequency band. When there are more users connected, the interference will be larger.


5G WiFi advantages: Since 5G signal bandwidth is wider, the wireless environment is relatively clean so that there is less interference. The network speed is relative more stable and it can support higher wireless speed.

5G WiFi Disadvantages: 5G signal frequency is higher, attenuation is greater when spreading in the air or obstacles, and the coverage distance is generally shorter than 2.4G signal.


5G WiFi needs to be supported by devices connected to the network

5G WiFi is only supported by dual-band routers! In addition to the support of a wireless router, 5G WiFi needs to be supported by devices connected to the network. In other words, old mobile phones, laptops, and tablets do not support 5G WiFi networks. Even dual-band routers can only search for 2.4G WiFi. The internet. However, in recent years, new smartphones, notebooks, and tablets can support dual-band WiFi, and can search for 2.4G and 5G WiFi at the same time.


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 frequency 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 shorter.


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 this frequency band. The 5G frequency 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 shorter.


If you have a large walking range, it is recommended to connect to ordinary 2.4G WiFi, mainly because the 5G band WiFi signal coverage has no advantage compared to 2.4G. If you are near a dual-band router, it is undoubtedly recommended to use 5G WiFi, which is more stable in terms of signal and faster network speed. Generally speaking, 5G WiFi is preferred.
