Curious to know if you need device movement to calculate a set of distances to an AP given that you may not know the AP' full strength (0 metres) and therefore would need to perform at least two measurements at different distances to establish the drop off rate and from that calculate the AP location.
can anyone please explain how it gives location coordinates without any reference point to start with? is it pinging to access points and getting their locations first?
what if we have more than 3 wifi access points? Also is it possible that with 4 wifi nodes gelocation api returning "not found" but on adding one more node i.e 5 nodes now-it may return lat long ?
How do I get my latitude and longitude coordinate values of current location, which could be displayed in a text area or at least as a toast in my Android program in Android studio(Gmaps API of it) ?
But they use WiFi -- so they can sniff for WiFi access points around them, getting the signal strength, and use that to trilaterate their location, which they could then broadcast.
@lmoroney That's Great..! Is that possible to add offline features? What I mean is...Can we get the rough estimate of the distance between APs approximately in meters and not through Google API calls..? And What about the technics need to be used while estimating a multi-storey building..which involves many floors and finding the exact floor..!
You could use the FSPL formula to calculate distance using trilateration yourself if you know where the access points are. For a multi storey building, I recommend using the Places API if that building has a lot of known places -- like a mall.
Thank You for your Response..! It's Great to Know this feature...Will play around this FSPL and Places API soon...! Looking forward to more videos, updates like this..!
