I wonder how well this works on average. If this would work well enough I don't believe we'd be seeing all the integrated GPS units for the claimed purpose of servicing E911. Those things do add a real cost to the phone that cell phone providers are eating. If I were to try to mask the location of a cell phone, I'd simply stand within a few blocks of a cell tower and put the phone in the focus of a deep parabolic dish pointed at the cell tower of interest. I'd like to see the neighboring towers pick up a phone that is commanded to run at low xmit power with what is effectively a tight beam talking to the closest tower. But I do agree, hiding one's general location to within a few cell-tower radii is not possible. -wolfgang -- Wolfgang S.
