If you really want to shut down a dopey chatter box, then you'll need to acquire a cell phone jammer.
WHAT IS A "JAMMER"?
Cell phone jammers are devices that create a temporary "dead zone" to all cell phone traffic in their immediate proximity. Jammers are typically used by the police and military to control or disrupt communication during hostage situations and bomb threats. Traditionally, jammers were large antennas mounted on trailers that had to be pulled behind a truck. They now come in a variety of shapes and sizes including models that are about the size of a cell phone.
USING A JAMMER
Because jammers now come in much smaller sizes, they are very easy to carry around. Portable personal jammers will fit into the palm of your hand or easily slip into your coat pocket. So the next time someone on your commuter bus refuses to shut up, you can just reach into your backpack and turn on a temporary "dead zone" with your jammer. Then get back to some nice peace and quiet.
RANGE & FREQUENCY
Most jammers only have a range of about 50 to 80 feet and will only effectively jam your immediate surroundings. Mobile blabbermouths will just think they've hit a dead spot in their cell phone company's coverage until they leave your jammers immediate vicinity. Stronger jammers are available to cover larger structures like office buildings, movie theaters and churches. They look like a miscellaneous metal boxes with wires sticking out and are usually mounted on walls or ceilings (see image on right).
