But you can already tell what house you're in with triangulation, and even the room.

Source on this? Maybe you can do it if it's combined with wifi/bluetooth signals, but I doubt you can do it with cell towers alone.

Yes you can. I used a jailbreak app on ios6 and I used llama on Android for this.

I got my own room in my house with it, back in the 3G/4G days. I'm not sure what modern software and hardware can do it now, but I'm pretty sure it's even more accurate even without 5G.

Seems like the figures they're giving is with wifi/gps signals, not just cell tower alone.

I am sure they were able to do it without it, but others can interfer. Triangulation was already a thing in the courts. https://www.eff.org/deeplinks/2018/06/victory-supreme-court-... It's in Carpenter vs US, for deducting he robbed a store from just the cell phone signals.
