Re: This is good for AT&T and AT&T wireless customers
That's exactly how it works, it establishes a VPN back to your wireless provider. Everything is routed over that VPN.
As far as charging for data (or even minutes/SMS), keep in mind that you're still using cellular frequencies, which the carrier paid billions for the privilege of having access too, and femtocells do not come with zero impact on the macro network. The power/channel management logic on the back end of these devices is exceedingly complex, it's not just another Wi-Fi AP.
