I'm giving serious thought to throwing down money on copper paint to make a faraday cage undercoat next time I feel like a different color scheme. People today are subject to surveillance capabilities that George Orwell and the Stasi could not even have dreamt of.
How do you plan on having cell coverage or even WiFi inside your home?
Microcell for cellular coverage, wifi shouldn’t be a problem since the transmitter is inside and you wouldn’t need to shield interior walls
And less interference from neighbours' Wi-Fi.
Wifi works fine inside a faraday cage. If I need cell coverage I can always go outside.
If you're so worried about surveillance that you're willing to turn your house into a Faraday cage, why would you have an active cell phone in your house (or provide a microcell that "they" can use for their own listening devices)?
Key word here bring "capabilities". Stasi did a lot worse with a lot less because the authoritarian and intolerant ideology that brought Stasi about was in itself a lot worse.
