I'm trying to obtain the longitude and latitude positions of existing access points within an indoor environment using Java (Eclipse). I understand that these are needed to complete the triangulation method. I have spoken to the IT team and they're unable to provide me with these readings. However I'm wondering if there's another way to do this?
You will need to work with signal strength. You cannot determine lat. & long. with wifi. It appears that a few iPhone apps leverage triangulation of wifi.
But for outdoor triangulation , the default is GPS.
