Understanding Cell Phone signal Jammers
Cell phone Jammers operate by emitting signals on the same frequencies as mobile phones, effectively overpowering and nullifying them. Since mobile phones are full-duplex devices that use two separate frequencies for sending and receiving data, Jammers can disrupt one or both frequencies, causing the phone to believe it has no signal. Basic jammers may block a single frequency band, while more sophisticated ones can obstruct multiple networks at once, such as CDMA, TDMA, GSM, PCS, DCS, as well as 3G, 4G, and 5G networks.
