Looking down the road beyond 802.11ax the working group is busy with a range of new capabilities. 802.11ax will extend the channels with almost the entire 6 GHz band which will allow for a big improvement in dense urban areas.
With more available channels the amount of interference will be reduced considerably. This will make Wi-Fi more practical for mobile devices in malls and larger restaurants etc.
802.11az calls for next generation location. The goal is improved absolute and relative location, tracking, and positioning of client devices (stations) using Fine Timing Measurement (FTM, based on round-trip timing measurement of a given transmitted signal) in place of the signal-strength techniques commonly used today. A final standard is expected in 2021.
802.11az will make it far easier for a taxi to be able to find the fare. In many cities cab services would be improved rapidly. Some cabs offer a hotspot so that fares can use a NFC mobile phone for payment.
802.11bb is being designed to bring Wi-Fi to moving vehicles. 802.11p is the current standard and 802.11bb is looking to improve the situation possibly by using some of the millimeter wave bands above 45 Ghz. Some of the ideas considered are intended for autonomous vehicles which can share information with one another.
Longer term the 802.11 working group has continued to bring new technologies and innovations into the standards which makes it possible for both businesses and consumers alike a level playing field.
