This technology has been publicly demonstrated about 3 years ago, but I imagine it has been done years and years back. It's really nothing mind blowing, just the way waves work, workaround believe it or not is the tin foil your walls.
There is now a free home assistant plugin to implement it at home lol. Crazy shit. Imagine what's possible with classified tech.
