Indoor navigation using WIFI signal strength trilateration.

Hi,

i am currently looking at ways to implement a wifi based navigation system using an arduino uno in combination with a wifi shield. The shield is able to detect wifi signal strength and could possibly be used to reconstruct the position of an arduc
