Hi Brani

Are the cellphones using BATMAN, or are they just STA of an access
point co-located with a mesh node? And is your mesh static, or can the
mesh itself move around?

I'm assuming your mesh nodes are static. Thus you can determine there
location once, using GPS, etc, and assume they are not going to move.

If the cellphones are STA, you can tell from the tables that BATMAN
keeps which mesh node they are behind. Thus if you know the location
of the BATMAN mesh node, your know the approximate location of the
cellphone.
