The Wi-Fi Alliance this week introduced a new generational naming format that effectively rebrands iterations of the 802.11 standard. Wi-Fi 6 refers to the 802.11ax standard; Wi-Fi 5 designates 802.11ac; and Wi-Fi 4 equates to 802.11n.
802.11ax is supported by several commercial products, including a Charter home router and a Ruckus access point, with more in the pipeline. The latest enhancement to Wi-Fi features uplink and downlink OFDMA, 8×8 multi-user MIMO and 1024 QAM.
