alt Hacker NewsI'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.
Xfinity/Comcast does the same thing. By default, the router they provide has a separate WiFi network supporting their distributed WiFi service. It's only for their customers, and it's not an open no-password network, but I'm certain they would offer it to any company that paid for access. They also have WiFi APs on telephone poles to broaden coverage.
If you live in a dense city, there's a good chance you can reach an open network. When I lived in midtown Manhattan, there were around 500 SSIDs reachable from my apartment.
