How Mobile Phone Jammers Work

A mobile phone signal jammer is used by nightclub and casino owners to stop cell phone use in the building. The jammer also stops Internet use through Wi-Fi network and even blocks Bluetooth connections. The cell phone signal jammer also puts an end to text messaging, so students cannot SMS each other, while the teacher is trying to teach.

The range of a personal cell phone jammer can be from 10 meters to 100 meters. The jammer can also work at a distance or behind walls. Portable cell phone jammers are small and pocket-sized, and look like cell phones themselves. The jammer fits into a pack of cigarettes, so it is easy to hide. The jammer works well, even when it is in an enclosure. Larger cell phone jammers are more powerful and have a range that can be measured in miles.

A cell phone jammer has three antennas, one each for GSM, 3G and DCS. The jammer works by broadcasting a white noise signal or a wave bubble. First, you have to charge the jammer for at least an hour. Then, you have to plug in the jammer, and turn it on, so cell phones in the proximity will have no service available and all calls are lost. Some cell phones switch to searching, which means their signal is knocked out. When you turn off the jammer, the signals normalize.

However, a cell phone jammer also blocks emergency calls made to doctors and first responders. For example, a jammer can stop the residents of a house to make a 911 call to the police, when thieves are burgling their house. This is why a jammer is illegal, according to telecommunications regulations in the United States. The FCC (Federal Communications Commission) thinks a jammer interferes with the public airwaves, and a jammer infringes on a person's right to use a cell phone. A jammer also interferes with medical devices, such as pacemakers, used by heart patients. You have to pay penalties, if you're found using a cell phone jammer.

Cell phone jammers are wanted by the federal government, law enforcement agencies and the military. In Iraq, terrorists use cell phones to trigger explosives. The U.S. Army can use a jammer to make mobile phones go dead, so that army technicians can deactivate the bomb. There may also be a law that allows officials to install jammers in prisons, to eliminate cell phone use by prison inmates.

You can buy a cell phone jammer on the Internet from foreign electronic companies. Some cell phone jammers can be fitted with frequency filters, so you only jam certain frequencies. Now that you know how cell phone jammers work, you can go to Mexico and use them over there, whenever you get rankled by a bothersome cell phone user.
