Walls and ceiling can be made "radio proof". It has an intitial cost much higher than, for example, jamming does; but is: 1.) legal, and more importantly: 2.) free (after upfront installation costs).
I work in an Archetectural firm and we have been installing this in buildings (police stations, jails, prisons, parts of hospitals) where we can't have radio / television interference. As a nice(?) sideline, you can't use a cell phone while in a room / building with RF insulation. I'm surprised that more theaters / restaurants haven't had this installed.
I've pondered that as well. A faraday cage is pretty damn easy to build and the fact that you're working with a very limited frequency range makes it even simpler.
To be honest the up front cost shouldn't even be that much higher, it's not like wire mesh is that expensive. Heck I'd be willing to bet someone has already sat down and worked out a ratio for doing it with just rebar and concrete.
