As the various LPWAN protocols have tussled for market position, the WiFi story has been the quietest, even though the IEEE has defined a standard for this market – 802.11ah – and the collective weight of the WiFi community completely dwarfs that behind any other connectivity option, even NB-IoT. The first arrival of 802.11ah silicon may start to change all that. There are many supporters of the idea that WiFi, and the IEEE 802.11 standards on which it is based, should cover all the connectivity bases from personal area to wide area; from low to high power; from sub-1 GHz to millimeter wave spectrum; and from low to multi-gigabit data rates – and therefore support almost any use case.
