I'm not sure of the current state of it, but a few years back specturm was selling access to a private network based on consumer routers. Tmobile could partner with them so that one of their customers could go through spectrum instead of the cell towers in cases where connections were spotty.

That's exactly the sort of thing I could see LG piggy backing on. Your neighbor might have spectrum so the LG TV connects to it's private network to phone home.
