What interferes with mobile phone signals?

A "cellular jammer" is a device that wasspecifically created to cause a "dead zone." When radiosignals are blocked, this is a dead zone. Cellular jammersgive out signals at the same frequency as mobilephones. This thereby interrupts the signal and blocksit.
