On the gsm positioning faking

[Fabio Pietrosanti (naif)]

Hi guys,

i just looked at 27c3 talk on
http://27c3.iphoneblog.de/recordings/3952.html (i really wanted to be
there!) and heard about the concept of being able to fake gsm based
position systems.

Which could in theory the distance that could be faked respect to the
knowledge that the BTS can acquire?

I mean, the modified timing information provided by phone running
osmocombb, how many meters distance from BTS could be?
