So how does it work? I assume the LTE USB modem operates on T-Mobile frequencies, so does that mean it accepts all T-Mobile customers? How's authentication done? How does T-Mobile permit you to use their frequencies?

This is not about hosting an LTE 'access point'. It's about creating a access point which uses an LTE uplink. I agree, the title is somewhat misleading.

Correct. If you were to create an actual “access point” you will have the FCC and other agencies knocking on your door within minutes.

Within minutes? Seems optimistic.

I don't think their response time would be nearly that quick. All the stories about Stingrays would imply that this actually isn't very well policed (FCC enforcement is reactionary. The carriers could be proactive, but then would discover the Stingrays. And if carriers were complicit with Stingrays, then Stingrays themselves wouldn't be necessary).

I would also think the widespread deployment of legit femtocells would provide a decent cover.

But yes, it is generally illegal. (Though this hasn't stopped OpenBTS from being developed)

What you're thinking of is called a base station.
