Cell Phone Jammers
Who does not have or use cell phones as of today’s 2010? “According to the Cellular Telecommunications and Internet Association, almost 195 million people in the United States had cell-phone service in October 2005.” The statistics shows that cell phones are everywhere these days. It’s great to have cell phones and be able to call anyone anytime in the day whether it’s for socializing or seeking for help if stuck anywhere. However, people have forgotten the purpose of having this wonderful handheld two-way radio and its usage. As a matter fact, cell phones users are becoming ignorant and careless day by day when they forget when to stop talking and if it is in public places, like restaurants, movie theaters, shopping malls etc than the surrounding public suffer the most.
What is a cell phone jammer and how do they work?
Cell phone jammers are devices that create a temporary "dead zone" to all cell phone traffic in their immediate proximity (range). They come in two versions, one for European and the Gulf States GSM networks (900 & 1800) and one for the U.S.A & Canada (800 & 1900 MHz) networks. The range of a personal cell phone jammer can be from 10 meters to 100 meters. 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. Firstly, the jammer needs to be charged for at least an hour before it can be turned on. Secondly, once they are charged and turned on, cell phones in the proximity will have no service available and all calls will be lost. Some cell phones will switch to searching, which means their signal is knocked out. The signal will be normalize once the jammer is turned off. It is like the concept of on/off switches where if it is high you get output or nothing if it is low.
