Abstract
A system for disabling mobile telephones in circumstances where their use would prejudice the operation of critical systems (e.g. on an aeroplane, or in a hospital), or would irritate others includes a pair of RF beacons situated at the entrance to the controlled zone. The phone has receivers sensitive to the beacon outputs, and is adapted automatically to shut down into a standby state when passing in one direction through the beacons, and to re-activate when passing in the other direction.
