Big walls
One of our clients at work has a satellite office in Beavercreek with 36" thick concrete walls. Needless to say, cell phones, radios, wlan are worthless inside this office. The door on the office is solid metal, at least 1' thick, and looks like it could be used to seal off a bank vault. All this crazy shielding was originally put there to accomodate a linear accelerator, but for some reason that plan never materialized. Now they use the room to do Nuclear imaging, but the concrete walls are completely unneeded for this, so they are just a hindrance. Anyway, our job today was to run cat5 into the concrete room to connect to a wireless ap on the outside. If the 36" walls weren't fun enough, there was 20' of ceiling that was drywall instead of removable ceiling tiles like everywhere else.
Yay happy joy.
