Anyone who watches TV crime shows knows that the cops can trace the signal from a mobile phone, and by triangulation can pin down it's location with great accuracy.
The relentless march of technology has extended that capability to those who have invested in the latest mobile phones. Those with the necessary know how have the ability to keep track of their friends - and can even fine tune that location to a particular shop, pub, park or housing address.
It has advantages. Users can share information by exchanging photographs of their locations and invite friends to join them, and those same maps can provide information on facilities available nearby, including their opening hours.
But - there is a downside.
There is an inevitable lack of privacy - which hackers will exploit, and at present this technology is unregulated in Australia.
Is there ever a time you would prefer your wife/husband/friends not to know where you were - and what you were doing ? That sort of privacy may be a thing of the past, because if you have your mobile phone with you the world will have that information immediately available.
Something to think about - and maybe a good reason to go and find an unsophisticated mobile phone that has none of this state of the art gadgetry.
Remember the days when mobile phones simply let you make - and receive - phone calls ?
Maybe they were " the good old days " !
