Mobile phone auto-disable
It is now possible to use triangulation from base stations to determine the position of a mobile phone. A useful application of this would be to create 'no-phone' zones, where a signal could be sent to the mobile to switch it off when it is within a designated area.

This could apply to theatres, hospitals, military bases: indeed any location where the user is instructed to switch their mobile off.

Reward: No more interuptions in the theatre
