FAQs

What is 802.11ax?

The IEEE 802.11ax standard, also known as the High-Efficiency Wireless (HEW) or Wi-Fi 6, builds off of the 802.11ac 
and delivers a better experience in typical environments, and a more predictable performance for advanced applications 
such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and 
Internet-of-Things (IoT). 802.11ax is designed to use both 2.4Ghz and the 5GHz bands, unlike prior standards.
