at&t 3g microcell

Since we've cancelled our Lingo VoIP service we're now relying solely on our cell phones at home. I've installed a 3g microcell in my living room for my wife's cell coverage. She now has reliable cell service throughout the entire house. Before we had the microcell the coverage was poor and unreliable.

We bought the microcell at the AT&T store in the Mall of NH. It only took about 15 minutes to set up. It is connected to my layer 2 switch behind our home firewall. My wife's phone has an MCell icon instead of the normal 3g icon.

Wondering how much RF this device is sending into my living room.
