Hello, friend!
Dual-band Wi-Fi usually has two channels: 2.4 GHz and 5 GHz. Single-band Wi-Fi only has 2.4 GHz channels.
2.4 GHz signals have good penetration and long transmission distance, but the transmission speed is slow.
5G signals have poor penetration, short transmission distance, but fast transmission speed.
The 2.4 GHz frequency band has strong anti-attenuation capability in indoor environments. However, many devices use the 2.4 GHz, frequency band. Therefore, there are many interferences, which cannot ensure sufficient stability.
5 GHz, including three UNII frequency bands ranging from 5.1 GHz to 5.8 GHz; This frequency band has the greatest advantage in that it is seldom used and has little interference, ensuring transmission quality. However, the disadvantage is obvious. The indoor anti-attenuator capability is weak.
Thanks!
