What is WiFi 6E?

WiFi 6E is based on WiFi 6, with the E standing for Extension. W-Fi 6E uses the same 802.11ax technology for wireless connection, but extends this to a new WiFi band called 6GHz. It utilizes up to 14 additional 80MHz channels or 7 additional 160MHz channels, which makes it suitable for applications such as HD streaming or VR experience.

Only devices that support WiFi 6E can connect to the 6 GHz WiFi, devices that only support WiFi 6 can only use 2.4GHz and 5GHz WiFi.
