    That’s pretty fucking nuts if true. I may need to go back to physics class but I’m pretty sure concrete is typically used as a shield to block the more penetrating x-rays, so the less powerful communication broadcasts don’t typically stand a chance. It’s got me wondering how they are doing that - what’s the range on these things when they aren’t broadcasting through concrete??

      Hmm article says 6GHz, but I’ve also had great success going through brick walls and refrigerators using mikrotik wireless wire - it’s 60GHz and the ship as a pair of PTP radios. I just tape them both facing the wall on either side and I got a gig through that. It also helps that the wireless wire has like a 60° directional antenna inside. My old apartment has an unused brick chimney structure that’s at least 2 brick walls that goes from basement to roof and I was surprised I was able to get it to penetrate that too including our refrigerator which was backed up against that spot on the wall.
