OK, I didn't know about "timing advance". Obviously that gives at least a radius from the tower.
Your link is for GSM and states a 550 meter resolution, but I tried looking up LTE and I think it said 10 meters there.
I also understand modern (maybe next generation) towers will use directional transmission to avoid sending signals in all directions. Even if that's a 20° beam, that narrows don't the location by a lot.
