IEEE finalization of 802.11ah is far along and already into what’s known as the technical phase
It’s really sad that 802.11p (5.9 Ghz DSRC for Connected Vehicles) never got this much attention and rapid pace toward deployment – whose fault was that? There was plenty of money thrown at it. Since cars are part of IoT I suppose they will need to support HaLow also. This will fall on innovators, not government (BTW it seems NHTSA decided not to issue a DSRC mandate so far).
