How do Cell Phone Jammers operate?
Cell phones are everywhere. According to the new research, approximately 195 million populace, in United States of America use cell phones. Cell phones are also omnipresent in Europe. Cell phone jamming is same as disrupting any other radio communications. A cell phone functions by conveying with service network by a base station or cell tower. Cell towers split up city area into small cells. As the cell phone user rides down the street, the signal transfers form tower to tower.
The cell phone jammers use the similar radio frequencies that cell phone uses. The cell phone jammers operate with certain frequency; it disrupts the communicating amongst the cell phone base station in the tower and cell phone. People usually refer this as denial of service attack. The jammer refuses service of the radio-frequency spectrum to the mobile phone users inside range of the jamming equipment. The cell phone jammers operate with the help of tuning circuit, noise generator, voltage-controlled oscillator and RF amplification.
Mobile phones uses full-duplex device. It means they utilize two different frequencies. One frequency is for listening and the other frequency is for talking. Some cell phone jammers operate by stopping any one of these two frequencies of the mobile phones. In addition, this eventually affects both the frequencies. In this situation, the user thinks that there is no service available as he/she can receive only one frequency.
