Jamming Cell Phones Is The Best Way To Say Do Not Disturb
In these technologically advanced times of internet, laptop, PDA, Cell phones and ultra modern machines; it is hard to let them go unnoticed. But they have their own demerits too. You must have gone through a situation when you were in an important and relevant situation and the ringing of a cell phone disturbed your flow and harmony. It has happened to all of us and at times we are compelled to think why ever the land phone had to be mobilized.
Citing a simple example, you and your girlfriend are sitting in a theatre enjoying a movie and just when there comes a twist or a key dialogue is about to be delivered someone's cell phone starts ringing. You could have forgave him or her but that incident did not end there the concerned person not only receives the call but starts talking endlessly at the pitch of his or her voice. At that particular moment if you had the power you would have destroyed the entire cell phone industry. This would not have been the case if that movie theatre admin had installed a Mobile Phone jammer. Not only movie theatres but restaurants, concerts, shopping malls, places of worships etc all suffer from the same problem. Many a people are there who do not know the basic courtesy to switch off or at least make their mobile phone silent in these types of places.
Now we will come to mobile jammers. These are devices having a finite range within which mobile phone will not be able to work. They will be useless within the limits of a jammer. Before foraying into the working of a cell phone jammer you should know how a cell phone works. It works by communicating with its service network via cell phone towers present in various areas. As people move the signal gets transferred from one tower to another. The jamming device transmits the same frequency as the cell phone thereby disrupting it completely. As the same frequency overlap the communication between the mobile phone and the tower gets interrupted and the mobile phone ceases to work. There are various types of jammers with different ranges. Some are as small as a suitcase with arrange of few meters while some can be as big as a room and have a range of few hundred meters.
Cell phones have different frequencies for listening and talking, that gives the jammer extra labor of blocking both the signals so as to effectively cease the communication. Even if it blocks one of the frequencies the mobile phone is tricked into thinking that it has lost signal and is unable to find the service provider's frequency and is said to be OUT OF RANGE. These features allow them to be placed in special types of prisons, for e.g. many state prisons have GPS jammers installed. This is done to prevent the inmates from trying to operate their organized crime even from inside penitentiary. Mobile jammers are a gift of science and should be used effectively and intelligently.
