802.11bf Wi-Fi 7 Sensing works with all frequencies, 2.4 and up.
Even if Neighbor 2 turns off their router, Neighbor 1 could passively use the radio waves from Neighbor 3's router to surveil reflections from Neighbor 2, including keyboard typing, heartrate/breathing, location and physical activity.

- judge2020 5y agoThe problem with this neighbor-spying fear is that "complex math using data from radio waves to sense stuff" is already possible and readily available by anyone willing to study and put in the world of building it, wifi 7 isn't suddenly enabling that part of rf analysis or mathematics.

- EricE 5y agoyes, but the real threat with this is not that it makes something possible that is already possible, but it makes the barrier to use that tech a LOT lower. Wrapping my house in tin foil is sounding a lot less conspiracy theorist now! Actually my house is going to be stuccoed - I wonder if they are using a metal mesh that I can ground. Hmm...
