I love this! A good possibility in preventing people from locating your whereabouts 24/7 or listening in. Anechoic chambers were my peace zone - and this is like peace of mind everywhere you go.
There was a time I used to carry copper tape with me all the time to cover my cards and made a pouch out of it. And i used to stick ferrite beads at the edge of all cables . And once I made loop antennas from old RF cables, connected them to a handheld signal analyzer to detect how much signals that's around me, and I found 400 MHz harmonic jamming my car alarm near a transmission plant. I think this could help detect hidden cameras in hotels or Airbnbs as well, as they typically use RF bands to transmit video signals.
Would be cool to get a signal generator, turn on satellite modulation signals and measure reflections and see how many signals it suppresses (or see what signals you can pick up near you) but it needs a satellite dish to detect. Actually if you have a sign gen and an analyser and some loop antenna, check out your radiation from laptop, your phones at higher frequencies. It's one reason why I stopped using my laptop on the lap - because Cispr tests didn't test high freq harmonics.
This innovation is very cool, the paranoid me appreciates it.
