How mobile phones let spies see our every move
Government's secret Celldar project will allow surveillance of anyone, at any time and anywhere there is a phone signal

Secret radar technology research that will allow the biggest-ever extension of 'Big Brother'-style surveillance in the UK is being funded by the Government.
The radical new system, which has outraged civil liberties groups, uses mobile phone masts to allow security authorities to watch vehicles and individuals 'in real time' almost anywhere in Britain.
The technology 'sees' the shapes made when radio waves emitted by mobile phone masts meet an obstruction. Signals bounced back by immobile objects, such as walls or trees, are filtered out by the receiver. This allows anything moving, such as cars or people, to be tracked. Previously, radar needed massive fixed equipment to work and transmissions from mobile phone masts were thought too weak to be useful.
