Advanced Tracking Techniques Re: [FedCom] Update: Unknown Frequencies

[Tom Greenwood]

With GPS receivers now built into most if not all cell phones manufactured
in the last two years, for all practical purposes you can now be tracked
down to within 50 feet assuming that you can get a good fix on 3 or more
satellites while indoors.  Believe it or not, I have on several occassions
been able to get a fix with my portable GPS receiver while inside my house
and not standing near the windows.  Must have been a perfect constellation
of satellites.  There are many other aspects of cell phone technology that
make it very easy to track your location to a relatively small area even
without the use of GPS.  If you want to communicate and not get caught, you
had better resort to the old days of cutting letters out of the headlines of
newspapers and pasting them to paper.

Remember Kevin Mitnick (computer hacker) &  John Markoff and Tsutomu
Shimomura's  book "Takedown"...

During the final "take down" chapter of the book --  Mitnick is using a
cellphone/laptop computer interface to hack into a site & the feds (don't
call if it was the FBI, USMS, or USSS) are able to track him by first
finding out what cell tower (lobe of cell tower) his signal is hitting (and
I'd assume the specific radio frequency & cellphone number/EN code  & than
with a mobile/portable device they are able to track him down to the
specific townhouse apartment in a fairly large complex.   Very interesting
use of technology.
