Some cell-phone jammers are designed to resemble real phones, while others come in larger sizes such as briefcases or even bigger.
Despite the varying ways in which different cellular systems process signals, radio signals that have the potential to be disrupted are utilized by all cell-phone networks.
Mobile phones are full-duplex devices, which means they use two separate frequencies, one for talking and one for listening simultaneously.
Less complex devices block only one group of frequencies, while sophisticated jammers can block several types of networks at once to head off dual-mode or tri-cell phones that automatically switch among different network types to find an open signal.
