That's why even though Google is building their own network with their Project Loon balloons, they will still have to work with the big carriers to use them in the US (which I believe they plan on doing eventually). It's Google's hardware, but the frequency band being broadcast by that hardware will be owned by Verizon, AT&T, T-Mobile, or Sprint. Google will essentially be just renting their hardware out to the carriers so that the carriers can fill in gaps in their network that would be difficult or impossible to fill any other way.
