With 6 ghz wifi you'd need a cage with a size of around 1mm irc.

    Foil is cheap enough and a good isolator for plenty of things.

    So if you don't want someone to measure your heartbeat and to physically know where you are at all times your only option is to cover your entire living area, including the windows, in aluminum foil?

    I guess what I'm getting at here is that this situation is deeply, deeply fucked.
