Also known as Wi-Fi 6 was ratified in 2019, this standard supports both 2.4 GHz and 5 GHz bands with theoretical data rates up to 10 Gbps. It improves spectral efficiency in dense environments through OFDMA (Orthogonal Frequency Division Multiple Access), MU-MIMO for both uplink and downlink, and BSS (Basic Service Set) Coloring to reduce interference. 802.11ax is designed to perform better in high-density environments such as stadiums, offices, and apartments
