Visible SSIDs are absolutely used to fingerprint location.

  At least in the early days, every iPhone maintained a local lookup table between ssids and gps coordinates in a SQLite database. https://www.networkworld.com/article/752872/security-apple-officially-responds-to-ios-consolidated-db-tracking-file-controversy.html https://www.networkworld.com/article/752872/security-apple-o...

    That doesn’t mean seeing an SSID means you are at exactly that location. If you are in a city you see 50 SSIDs at any given moment. Are you at those 50 locations at the same time? No. Is there a way to triangulate where you are exactly? No, its unreliable and not an exact science.

      >Is there a way to triangulate where you are exactly? No The phone knows the signal strength of each ssid. Why can't it triangulate where it is?

        It can and does.

      you're all over these comments trying to convince everyone that SSIDs can't be used to determine location, yet you don't know how triangulation works? are you trolling?
