Wasn’t that a known thing already? I mean humans are a moving interference and partially reflect the microwaves, so its kinda obvious that its technically possible to do that… That would btw likely work with Radio waves as well, probably harder however, because they cover more area and therefore have more background noise.
I think the main difference is how ubiquitous these wifi signals are and the fact that the signal is very homogeneous, allowing for the ai patterns to work on a large scale.
Yeah - in article, it reads the resolution of data is significantly higher.
