The Alliance's announcement briefly describes the new naming scheme, which includes renaming 802.11ac to Wi-Fi 5 and 802.11n to Wi-Fi 4 and includes the requisite quotes from manufacturers praising the Alliance for its wisdom.
The quotes not withstanding, we'll all get to see how router makers handle the transition. A quick check of Qualcomm, Broadcom and NETGEAR's 11ax landing pages show none have yet made the change. (NETGEAR - feel free to use the rework of your AX page's header above. You're welcome.)
Only Marvell has gotten with the program quickly with its Wi-Fi 6 announcement and Wi-Fi 6 Solutions landing page (although it retains the https://www.marvell.com/wireless/80211ax/ URL).
Given the industry's penchant for each manufacturer doing its own rebranding of technology standards, this will be interesting to watch. I can imagine the joy in Wi-Fi product marketing teams as they face the task of updating websites, brochures and product boxes to fall in line with this new program.
The main advantage this gives the Wi-Fi industry is that it lets it pit "Wi-Fi 6" against the cellular crowd's "5G". Let the marketing games continue...
