You people are fucking retarded. This is the most primitive form of echolocation imaginable. And even it was something to be concerned about, you're not running some closed source firmware that can and has already been doing much worse things for your privacy, right...?
OEM router firmware sends device MAC addresses and whatever other crazy shit back to home base. That is significantly worse than this baby shit echolocation.
