Most of us might have gone through an embarrassing situation of getting disturbed by a cell phone ring while we were busy attending important seminars, interviews or negotiating with clients. A single cell phone ring will spoil the entire spirit & make us feel irritated. Even some of us are seen to stop using mobile phones for temporary period. But this is not the right solution as it might result in missing out our emergency calls. Therefore technocrats have invented an innovative device called mobile phone jammer that helps us continue with our important assignment without getting disturbed by phone calls.
It is true that mobile phones are important communication tools but their wide scale use in places like churches, hospitals, libraries, mosques, restaurants, movie theaters, concerts & shopping malls have caused great inconvenience to the people present around. And phone jammer has brought effective solution to this problem. In earlier times, the use of jammers was limited in the defense sector but later it sneaked into normal people's life. Now the mobile phone jammer is found to be used everywhere starting from prisons & dentition centers to restaurants for maintaining security as well as privacy. With the installation of cell phone jammers, people don't have to either switch off or keep their mobile phones in silent mode.
A cell phone jammer is an electronic device which is capable of blocking cell phone signal within a specific radius. Within this range, no cell phone will be able to either receive or transmit the signal. It works on the basis of same technology used for disrupting any other kind of radio communication. A mobile phone operates by establishing its contact with the service network through mobile towers present in different areas. These towers help catch the signal which continues to change with a change in the location of user. The phone jammer intervenes by transmitting the same radio frequency as that of the phone & break up the contact between the mobile phone & tower. As a result the cell phone loses its work ability. Many types of phone jammers are there whose operational area is limited to a certain range. While some of them are found to be of room size with few hundred meters range, others are like small suitcase with few meters range. However, the price of jammers used to vary a lot.
