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.

The 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.

Removing the PhD-level knowledge requirement from this particular mode of being an asshole doesn't sound like much of an improvement

yes, 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...

It makes it suddenly ubiquitous when all new WiFi devices use the new standard.
