Signals CDMA GSM Killer

Fast-forward to the 21st century, and consider a similar problem: annoying cellphone users. If you want to silence that annoyance, nothing so crude as a nerve pinch is required; science has provided a technological answer: cell phone jammer.

Electronically speaking, cell-phone jammers are very basic devices. The simplest just have an on/off switch and a light that indicates it's on. More complex deviceshave switches to activate jamming at different frequencies.

Several theater chains are becoming vigilant in preventing cell phone use during a movie - could small radius jammers be a safe and physically unobtrusive alternative in these situations? Granted, the glow from a cell phone is almost as annoying as the accompanying conversation, but blocking phone transmissions within parts of a large public venue does not prevent communication of wide-scale emergency alerts, as long as the entire area is not blanketed by jammers.

It is quite easy to see gsm jammer installed in the majority of theaters, concert halls, sporting events, and religious venues within the next decade. With the constant attention of public manners, it is inevitable to use jamming devices.

In any case, the presence of mobile phones in these places has always had a bad effect. So in order to avoid the abuse of mobile phones, and politely remind them, GSM jamming equipment is indispensable. That is why analysts say the demand for jamming devices will double in 2017 from a year earlier.
