The frequency range from 5.15 GHz to 5.85 GHz, which is unlicensed and used for many communications applications, including Wi-Fi and cordless phones. 5G became widespread after version 802.11a debuted.
The 5 GHz band is also used in the subsequent 11n, 11ac and 11ax versions of Wi-Fi.Running WiFi with 5GHz is the largest feature of 5GHz, which results in less channel congestion in the higher frequency band.
Taking the WiFi signal of the fifth generation 802.11ac protocol as an example, the transmission speed of 433Mbps can be reached at 80MHz, and the transmission speed of 866Mbps can be reached at 160MHz bandwidth, which is fundamentally different from the 2.4GHz transmission rate.
In addition, the advantages of 5GHz WiFi are also reflected in the frequency band resources, 2.4GHz non-interference band resources only 3, but there are 22 under 5GHz, assuming you imagine these bands as fast lanes, then 5GHz is obviously less prone to signal congestion, data transmission is more fluid.
WiFi transmission distance of 5GHz is short, the signal attenuation is significant, but the transmission rate is higher.
