Wi-Fi 6, also known as 802.11ax, is viewed by many to be game changing, as it’s the first major architectural change to the wireless LAN since its inception. Unlike other standards, which were just faster versions of the previous incarnation, Wi-Fi 6 is built from the ground up to support a world that is hyper-connected over Wi-Fi. To accomplish this, Wi-Fi 6 includes several new features and design enhancements.
OFDMA enables more clients to connect to access points
Many industry people I have discussed Wi-Fi 6 with believe the most important new feature is something called orthogonal frequency division multiple access (OFDMA), which allows multiple clients with varying bandwidth requirements to be connected to a single AP simultaneously.
