This jogged some memories! Was working on something that used radio waves to detect objects and humans ~5 years ago, I see that we've come a long way since then.

One of our goals(abandoned) was to also extend to wifi routers, so I am excited to see continued interest in this space!

Thanks for sharing the paper; I'll certainly be taking a look at that research!
