In terms of passive signal blocking, I wonder if the chickenwire mesh that holds exterior stucco in place could serve as an effective Faraday cage? Or aluminum siding? I'm sure the metal roof and walls of a modular storage building would. Most businesses use metal studs to support interior walls, though I doubt their ~2 foot spacing would block wifi or cellular RF. In terms of active cellular jamming, that should be pretty easy to detect -- by standing in an outside doorway where you'd be exposed to inside AND outside signals, and then checking if your cellular bars fade out. That should indicate that you've been exposed to an internal jamming signal, since the external signal should still remain. It's hard to imagine that the advantage to a corporation of isolating the customer's phone would be worth the risk of FCC prosecution.

Your idea of mesh inside the stucco is way better than my idea of simply wrapping chicken wire all over the outside. Ha. It should work, as long as it all has electrical continuity and is grounded. I think that's where a lot of normal mesh in stucco or plaster falls short; nobody is going to bother to connect it all up with copper strips or whatever if that's not their explicit goal. Even if it's not, it should attenuate radio waves somewhat. Just not as a full-coverage Faraday cage.

> I wonder if the chickenwire mesh that holds exterior stucco in place could serve as an effective Faraday cage? I can confirm that. I've had a shed in the past where I've used chicken wire to secure insulation and it seems to work well, albeit unintentionally at the time.
