It is undeniable that we are now living in a much more advanced era which we called "the information era". In today's world, various kinds of electronic products have been emerged like the mushrooms after a spring rain. Among those, the spread of cell phones acts in an exemplary manner. According to the latest statistical data published by the International Telecommunication Union, the number of cell phone users up to the end of the year 2010 has reached 5.28 billion.

Since every coin has two sides, this crazy increasing has not only brought convenience to people's communication, but also caused much trouble to our daily life. This then leads to the coming of a cell phone jammer. There is a saying that everything comes for a reason. The cell phone jammer is no exception. A cell phone jammer is an electronic device that can temporarily block the cell phone signals that are in a close enough area to the jammer.

Traditionally, the cell phone jammer was used by the military and law enforcement officials to either stop or control cell phone communication during disputes or threatening situations. However, with the number of cell phone users being insanely increased, a lot of people are trapped into the dilemma of using or blocking the cell phone signals. On the other hand, a lot of area, especially the public places are now installing or tend to install the device in order to disrupt the cell phone signals for many users are just not so consciously about the trouble or interruption they bring about to others around them.

The cell phone jammer disrupts a cell phone just the same as jamming any other kind of radio communication. A cell phone works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or say cells. As a cell phone user drives down the street, the signal is handed from tower to tower. A jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell phone base station in the tower. Thus, people only need to turn the switch on and set the jamming frequency to make everything done. Here is one point that should be taken seriously when using or buying a cell phone jammer --- some less complex jammers work on only one group of frequencies yet some others work on several groups.

In addition, the range of cell phone jammers varied from each other, but the average kinds are often between 50 to 80 feet. So before choosing a jammer for yourself, please make sure that the range meets your needs.

To sum up, the popularity of cell phone using has brought convenience to people, but the abused using also causes problems. The coming of cell phone jammer can be regarded as a savior for those who want to remain a private and peace area in the public.
