What is a Cell Phone Jammer?

• A cell phone jammer is an electronic device that can temporarily disrupt any cell phone signals that are in a close enough area to the jammer. Cell phone jammers are often used by the military and law enforcement officials to either stop or control cell phone communication during disputes or threatening situations. With cell 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 cell phone use in some areas.

How Cell 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 cell phone is moved between these areas, the towers pass off the signals.
• A cell 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 cell phone and the nearest tower. Because the cell phone jammer and the cell phone use the same frequency, they effectively stop the other signal. Often a cell 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.

Note

• Signal jammers may not be permissible to import into certain countries due to licensing of broadcasts or other restrictions. Please check your country' s telecommunications regulations before placing your order.
