You don't get that level of granularity from a single ping, but you theoretically could from hundreds, the noise will tend to center around the true location.

Also consider that more than 3 stations probably were nearby.
- BelenusMordred 6y agoModern mobile networks choose the best 7 for the client but the number of towers within physical range getting pinged is quite substantial. It's an awesome, deep and nuanced topic certainly not suited to a political HN comments section. "Timing Advance" is the probably the jumpoff keyword for anyone interested. Mobile towers also use beam-forming in two directions and have a few other techniques to get better signals, the metadata involved with these things (if kept) essentially drops the error range down to GPS levels if not better.
