Which frequency band is added in the 802.11ax standard, also known as Wi-Fi 6E?

The 802.11ax standard, commonly referred to as Wi-Fi 6E, introduces the 6 GHz frequency band in addition to the previously established 2.4 GHz and 5 GHz bands found in earlier Wi-Fi standards. The inclusion of the 6 GHz band is significant because it allows for more channels and wider bandwidth, resulting in reduced congestion and improved performance, especially in environments with a high density of devices.

The 6 GHz band offers up to 1,200 MHz of additional spectrum, enabling faster data rates, lower latency, and enhanced overall network capacity. This is particularly beneficial for activities that require high bandwidth, such as video streaming, online gaming, and other applications that demand stable and fast connections.

In contrast, the existing 2.4 GHz and 5 GHz bands are not exclusive to Wi-Fi 6E; they have been utilized by various previous standards, such as 802.11b/g/n/ac. Thus, even though the 2.4 GHz and 5 GHz bands are also used in conjunction with Wi-Fi 6E, it is the introduction of the 6 GHz band that specifically characterizes this enhancement with the 802.11ax standard.
