As I told Andy, you need a "RayProof" or similar brand shielded
conference room. This is Faraday Cage, with a tight-fighting door,
etc.

I don't know what they cost, but I've installed one or 2. Outside
of labor, I suppose they might be in the $50-500K range or so,
for small (12'x6') ones.

Note it's a PITA to keep tight; as the door needs very
tight-fitting gaskets.

You'll need to bring phone/Ethernet in over fiber,
but that's not hard.
