Is That Cell Phone Tower Watching Me?

Posted by timothy on Monday October 13, 2003 @07:37PM from the correct-word-is-perceptive dept.

An anonymous reader writes "Cell phone networks, FM radio towers and television antennaes could all turn into pieces of cheap and dirty tracking networks that use passive radar, according to this fairly comprehensive article. These new systems are only a couple years away from roll out for uses such as small airport radar coverage but wild possibilities abound including using cell phone networks to track speeders, terrorists or even individuals walking on city streets."

This technology doesnt work if you dont have a cell phone.

All cell phones (at least the ones i've come across) emit a signal whether they are switched on or not. This ~2min heartbeat can be read/received EVEN without the battery in the phone. Obviously turning it off doesnt help either.
