What is a 5 GHz frequency band?
The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
The 5 GHz frequency band used by Wi-Fi technologies defines a specific range of frequencies that can be leveraged for wireless communications. This frequency range is separated into specific channels as illustrated in the following table:
Sep 15, 2023 · So, if you use a 2.4 GHz WiFi band with the best router, you can get a maximum speed of 600 Mbps. In the case of a 5GHz WiFi band, you can get double the internet speed, of a maximum of up to 1300 Mbps. This is the essential difference between the two bands.
The IEEE 802.11 Wi-Fi standard defines a range of channels and frequencies for wireless communication in the 2.4 GHz, 3.6 GHz and 5 GHz bands. Below is a list of common channels and their corresponding frequencies for wifi bands.

The 5 GHz Wi-Fi spectrum is approximately 500 MHz wide, and devices can use up to six larger 80 MHz channels for faster speeds.
WiFi signal at 20 MHz has a very distinct shape. This shape leads to overlap on other WiFi channels that can be used for setting up access points (AP). Unlike 2.4 GHz channels, all 25 of the available 5 GHz channels are non-overlapping at 20 MHz wide. Download our Best WiFi Channel Quick Guide.
There are three common channel widths used in WiFi networks: 20 MHz: This is the standard channel width for most WiFi networks, both in the 2.4 GHz and 5 GHz bands. A 20 MHz channel width provides a balance between data transfer rates and the potential for interference.
