Do you have any documentation on how this work ? Is there a name to this special protocol? Is it a recent addition to the wifi standard ?
Again a wifi AP doesn’t send data to a specific client. So how does an AP can enforce that one client can’t read a frame for someone else that is properly authenticated? How would an AP prevent someone spoofing mac addresses from receiving that data ?
I’m really confused by this feature I never heard of even when I was playing with aircrack and so on. Yes sometimes your mac address can get filtered but even that is not really difficult to avoid.
Sorry I have so many questions but I honestly did quite some “tinkering” with wifi years ago and none of this sounds familiar.
