copied!<p>Yes, this is indeed a solvable problem provided you make a few assumptions. </p> <p>Android OS has the functionality you would need to be able to analyze dBm of signals from Access Points (for those devs interested, see BroadcastReceiver and the SCAN_RESULTS_AVAILABLE_ACTION intent on WifiManager).</p> <p>As the signal travels away from the AP, the signal degrades at a quantifiable rate. Given you know the signal strength when the signal leaves the AP(spec's on the box) and when it arrives at your device, you could then come up with a distance the signal must have traveled to degrade as much as it had. </p> <p>This is where assumptions come into play. Anything between you and the AP has an effect on signal degradation, so if you were in, say your living room, and there were two walls between you and your access point the signal would arrive in a different state then if you were then to take a sledge hammer and smash down the two walls between you and the AP and then took a measurement. It's best to only use this in a place where there is nothing blocking the path between you and the AP.</p> <p>Also, you need at least 3 AP's to arrive at a single point in 2D space. Most people I know don't have 3 AP's set up in their house so you would need to ask your neighbor for the lat/long location of their AP's as well.</p> <p>All in all, a solvable problem but wouldn't necessarily work well in the context of your home, unless you were to include additional sensory data (3-D Map of your house, redundant AP's, accelerometer, GPS, etc) to come up with a solution.</p>
