Raytheon invents device to detect bomb-detonating cellphones

US defense contractor Raytheon has come up with a way to hijack the hijackers seeking to remotely trigger bombs via cellphone. The device includes a transmitter that mimics a cellphone base station plus a metal horn that concentrates the signal from a 10 milliwatt power source in a single direction. When the device is used to scan suspicious luggage,
it essentially tricks the concealed phone into thinking it's communicating with a new network base station while simultaneously blocking it from communicating with any genuine towers nearby. The bomb-detonating phone will reveal its phone number via a "handshake signal" sent to the Raytheon device, allowing the phone to be temporarily disconnected from the real network and prevented from receiving its detonation call. Should the suspect actually prove innocent, the phone will require only a reconnection to the network.
