Mobile phone in hard environment

Hi,
I have to provide mobile phone signal in a shielded environment.
Maybe the only way is by using an antenna that capture a sufficiently
strong signal outside the shielded room, and conveying that signal (
using a coax-cable ) inside it, at the end of the cable some sort of
repeater that provide the diffusion.
Does anyone has some other suggestion?
Or if the idea is correct, are those repeater in commerce?
And about the receiving antenna?
Thanks in advance.

Get you an external mobile cellular antenna. That already solves the
problem of operating a cellphone inside a "shielded" vehicle.

How about that antenna they sell on late night TV that sticks to your
battery? They claim is works anywhere.

Sorry, "anywhere" doesn't include inside a Faraday shield.

I would contend that it works as well in a faraday shield as it does in the
elevator.

Yep! The antenna does work anywhere! Any antenna works anywhere. An
antenna inside a Faraday cage works just fine, but, outside the Faraday
cage you still can't hear anything. :-)
