Let’s say I have 3 or more peers connected to the same WiFi Access Point.
If they all give me:
– latitude
– longitude
– their signal level (dBm) in respect to the same WiFi
Is this enough data to get the approximate location of the access point?
Yes, sort of. You would need a way to convert signal level to a distance from the access point. You may need to know the power of the signal (watts, mW, etc) in order to do this conversion. There’s some interesting reading from Cisco here, but being indoors can cause large errors because physical objects (like walls) in between the two antennae will cause further power loss in the signal.
There are a couple of calculators that might be useful at Radiolabs.
