1933key's professional Cell Phone Jammers (a.k.a. mobile phone blockers) transmit and broadcast radio signals in defined frequency ranges to cut-off and disrupt cellular communications between mobile cell phones and cellular base stations.
Privately developed advanced radio signal cellular jamming technology utilizes unique and intelligent interference techniques that effectively cut off cellular signals, creating 'dead cell-phone zones' to block annoying nuisances, secret cell phone tracking, cell phone eavesdroppers and cell phone triggered explosive devices (IEDs).
The signals are not really "lost" or "absent", but rather experience a "denial-of-service." 1933key's cell phone jammers are often referred to as mobile phone blockers, cell jammers, frequency disruptors, cellular immobilizers, and handset zappers.
"The physics of jamming a cell phone are actually quite simple. Cell phones operate by sending signals along a range of the electromagnetic spectrum reserved for their use. (In the United States that part typically is measured as either 800 or 1,900 megahertz; in Europe it's usually 900 or 1,800 megahertz.) All a cell-phone jamming device needs to do is broadcast a signal on those same frequencies, and it will interfere with any devices trying to transmit in that range. The net effect for a hapless cell-phone user? The phone's screen will simply indicate that no signal is available. Odds are most people won't even notice that their phones are being jammed. They'll just assume that they're in a dead spot—and feel annoyed."
