They have GPS. Rather than using up my data plan, it’s actually connected to the internet through my internet connection at home. I do, and my mobile phone is actually configured to use my wireless hotspot when it’s connected here at home. Google makes a relatively educated guess that “Gosh, if this machine is wireless, and we know that wireless is at this location, and that location is at this IP address, that could mean that any machine coming in from that IP address is probably at or around that location.” What your phone says about you – literallyĪnother way this can happen is if you happen to have a mobile phone. When people physically move, even if they’ve moved across country, their location is sometimes still shown as their old location because Google is still using the old location of that Wi-Fi hotspot. Google may think that router is in Washington when in fact it’s in Florida until they run another pass.Īnd that’s one piece of data, albeit a really good piece of data that Google has in front of it.Įven if you’re not using a hotspot, it’s possible that Google sees “machine A” coming through that hotspot and that hotspot then appears as “IP address X.” Well, if you’re wired to the same router that the hotspot is connected to then you also show up at that IP address. ![]() Now, it get’s a little bit more interesting. That must be where you are.” Where am I today, Google? Even without the SSID I believe they can capture some information that allows them to uniquely identify the hotspot.Ĭouple that with the mapping information that they are creating and they now know that, “If you’re connected through this Wi-Fi hotspot, I know where that Wi-Fi hotspot lives. As I broadcast my SSID, they would know the SSID of those hotspots. While they were doing that, they often actually had a Wi-Fi antenna hooked up so they could see and record at the different Wi-Fi hotspots available as they were driving around.įor example, when they drove by my house, they noticed that there are four Wi-Fi hotspots in this house. I’m actually somewhat surprised at how accurate Google can be at times, but you also have to realize that you give Google a lot more information than just your IP address.Įver seen StreetView on Google Maps? When they set out to create this view of their maps, they drove around all around these neighborhoods and took pictures of what the streets look like so you could see. ![]()
