RE: $400 million network upgrade for the Pentagon

Actually, yes you do block all cell phones and transmissions in these 
facilities.  I'm not sure if you have ever been in one but having cell 
phone access is simply not a concern.  Neither is much open 
comunication.  They are however smaller locked down rooms you would 
never lock down the entire pentagon that way.  I read earlier a point 
about buffer zones or distance between the building and outside world 
and this quite  common.  Many times as well these external areas contain 
electronic counter measures.  Classified environments are very different 
and have an entirely different set of requirements.
