The Cell Phone Jammer Story WHY do people use cell phone jammers? – Stop Obnoxious Cell Phone Abusers – Block Covert Eavesdroppers – Prevent Secret Tracking – Disable Cell Phone Triggered Explosives (IEDs) HOW do cell phone jammers really jam cell phones? Testing a Real Cell Phone Jammer 1) The Setup includes: – High-powered Spectrum Analyzer scans defined frequency ranges. – We used Tektronix’s robust SA2600. – Spectrum Analyzer configured to monitor cellular frequency 1800MHz, with span intervals of 20MHz. – Active cellular use detected within proximity. – 1933key’s 30m Cell Jammer (J15P01B) test application. 2) Turn ON Jammer. Watch spectrum analyzer signals burst, dwarfing all cell signals in the frequency range. 3) Witness EFFECTIVE cellular interference. Handsets and cell phones receive error messages such as No Signal, No Service or No Network Service. Cellular silence and anti-IED protection achieved. 4) Turn OFF Jammer. Watch spectrum analyzer signals normalize. By effectively knocking out cell phone signals, 1933key’s jammers help provide both protection & privacy. With 1933key’s 30m Cell Jammer (J15P01B), you see for yourself HOW Do Cell Phone Jammers ACTUALLY Jam Cell Phones to eliminate cellular intrusions and threats. By multiplying signals across target frequency ranges used by cell phones (handsets), 1933key cell phone jammers effectively disrupt signals to and from broadcasting base stations. The signals are not really “lost” or “absent”, but rather …
