So I guess those directional MIMO arrays can now give information back to the host controller. That is kinda creepy but also it could be super useful in the right circumstances.
The idea of DfP has been around for over 15 years but its only recently become possible outside of a laboratory environment. It isn't in HA yet because no one has bothered to write a module for it and there's almost no WiFi gear that supports it; either natively or through exposing the data necessary to make it work.
