The room of a cinema, a conference hall or a meeting, a church or a concert: these are all places or situations in which one may be requested to turn his mobile phone off, for different possible reasons which may range from the simple rule of keeping the place silent during a movie or a musical performance out of other people’s respect, to the need to avoid that any sensitive data or conversations may be leaked or transmitted outside.
Of course though, it may happen that someone accidentally keeps his cellphone on and it rings exactly when it shouldn’t, or that others do not turn it off on purpose, to allow a third party listener to remotely grab secrets in real time.
To avoid such kind of trouble, it may be useful to use a jammer, that is, a mobile phone breaker which prevents cellphones from working, making it impossible to communicate with the outside world, thus saving others from having to hear that annoying ring in the middle of an important scene, or preventing prying ears from listening to confidential conversations.
This is possible thanks to a jammer which would flood the area to protect with invisible signals (absolutely harmless for human health), preventing radio waves, which carry mobile phone signals, from reaching the area by making them illegible; so if someone keeps his phone on, he would have no signal and would not be able to place or receive calls, with no trouble for others and no unauthorized listeners.
The different types of jammers available on the market can block not only cellphone transmission, but also WiFi networks and Bluetooth connections.
