A Moblie Phone Jammers is an electronic device that can temporarily disrupt any mobile phone signals that are in a close enough area to the jammer. Mobile phone jammer are often used by the military and law enforcement officials to either stop or control mobile phone communication during disputes or threatening situations. With mobile phone use spreading almost everywhere and more people growing tired of being subjected to other people's personal conversations, some municipalities are considering whether to begin jamming mobile phone use in some areas.

 

How Mobile phone jammer Works

Cell phones communicate with a service network through cell towers. Cell towers are placed in specific places to provide service to small areas. As a mobile phone is moved between these areas, the towers pass off the signals.

A mobile phone jammer transmits on the same airwaves that cell phones do. When the jammer is activated, it is able to disrupt the signal between the mobile phone and the nearest tower. Because the mobile phone jammer and the mobile phone use the same frequency, they effectively stop the other signal. Often a mobile phone will boost its power at interferences like this so, to keep the signal disrupted, the jammer must be able to stay steady with the cell phone.

How Mobile Phone Jammers Are Made?

Mobile phone jammer are usually simple devices with typically only a switch to turn it on and off, a light to show that it is working and an external antenna to send the signal. If the jammer is more sophisticated, it might include controls to set the jamming for varied frequencies.

Small mobile phone jammer are usually powered by batteries. Often, the batteries are even the same as mobile phone batteries. Larger mobile phone jammer might be electrically powered.

Mobile phone jammer of Range

Mobile phone jammer typically have a range of between 50 and 80 feet. This means that they will only successfully jam cell phones that are within this range. As soon as the mobile phone travels out of range, the signal will return and you can again use the phone. More sophisticated mobile phone jammer might have larger ranges.
