Public occasions require the restraint of a cell phone jammer

But in New York, people with mobile phones are everywhere, whether in cars, shops or on the street. The cinema, theater, church, conference room, even at the funeral, cell phone ringtone will disgust, and users of externalized selves loosed even put mobile phone on vibrate file, also can cause interference to some facilities. That's why someone wants to use a jammer. After all, some places need quiet

Andrew, a San Francisco architect, boarded the train and sat next to a woman in her 20s. Because the woman along the way has been holding a mobile phone in the chatter, therefore, Andrew decided to be a "mobile phone vigilantes" - he put his hand into his shirt pocket, according to the size of a cigarette case inside the button in the mobile phone signal jammer. As a result, a powerful radio signal from the jammer is enough to cut all cell phone signals within a radius of nine meters.

Andrew said, "after I pushed the button, she went on for about 30 seconds, and then realized that the signal was cut off." Andrew said his first reaction was to feel "free" when he first realized he could cut off other people's cell phone signals.

With the rapid rise of mobile phone users, it is almost impossible to avoid the noise interference from other people's mobile phones in public. As a result, the United States began to have a small but rapidly growing "public order maintainer" and began to use a direct means, the cellular signal jammer, to resist the interference.

Many users are not like the ones mentioned above who want to be quiet in the car. From business institutions, schools, hospitals to Banks, even police agencies, there is demand for mobile jammers, and demand is growing because there are more and more things to do. A company in the United States is said to have invented a device that can interfere with camera functions.
