Mobile tracking devices on trial

Your mobile phone is a beacon - a radio transmitter in a box. Therefore it is possible to trace the signal and work out where it is.

There are now several web companies which will track your friends' and family's phones for you, so you always know where they are.

There are several reasons why you may want to track someone. You may be a company wanting to keep tabs on employees during work hours, or a parent wanting to check up on a child's whereabouts.
