Someone who speaks loudly on the phone and commutes the morning won’t be a problem? It turns out there is a way to end these calls –cell phone jammer
A cell phone signal jammer is a device used to prevent a mobile device from receiving signals from its base station. Originally developed for law enforcement and military purposes, cell phone jammers can prevent the exchange of terrorists and criminals. They are also common in prisons, and (apparently) cell phones don’t allow prisoners. Once the public has access to this technology, a lot of people – especially employers – will all want to use it, especially on the phone in big cities.
Every day phone jammer seems like a good idea: who wants to sit next to people on the train, was he the last details of their doctor’s chair speech? If you stop texting your best friends every two minutes, aren’t you doing more work in the library or at work?
Furthermore. Now use the phone very widely in class, students now think that they have the right to use the phone in class. You don’t listen to instructions, repeat directions as often as they are SMS texting on your phone listening to music, playing games or watching movies or videos. Some students make calls or even make calls during class. In this case, use a telephone jammer.
Needless to say, building a jammer yourself is also a necessity in prison. Since 2005, authorities have confiscated more than 6,000 phones in 55 North Carolina prisons, including 443 so far this year. Numbers rose steadily until 2012, higher authorities implementing security check at the airport prison like immigration procedures like metal detectors, x-ray scanners and trained dogs. Authorities said that after the kidnapping of a national law adopted by Janssen, the suspect phone prisoner is also a deterrent. Some facilities use “Administrative Access,” which is an expensive system that prevents unauthorized cellular signaling in some parts of the prison, but Solomon said signal interference can prolong the entire prison and make it more effective.
