I'm working on an indoor-positioning project where the users are carrying phones which can detect beacons located throughout the facility.

The phone app only knows the IDs of the beacons, and can detect the beacons' relative signal strength. I know the XY coordinates of each of the beacons. From this information I need to determine the user's position.

In the example below, the user's phone detects these beacons, with these relative strengths:

BeaconID   Signal Stregnth

    1            10

    2            3

    3            7

I know the user is located somewhere near those beacons - is it possible to determine their position based on this scant information?

Note - as far as I can tell the signal strength is relative and doesn't correlate to a specific distance. I've drawn the user midway between the 3 beacons but it's possible that they're located outside the triangle
