HOW do cell phone jammers really jam cell phones?
Testing a Real Cell Phone Jammer
The Setup includes:
High-powered Spectrum Analyzer scans defined frequency ranges.
We used Tektronix's robust SA2600 Spectrum Analyzer.
The Spectrum Analyzer is configured to monitor cellular frequency 1800MHz, with span intervals of 20MHz.
Active cellular use is detected within the proximity.
1933key's 30m Cell Jammer (J15P01B) used as a test application.
Turn ON the Jammer. Watch spectrum analyzer signals burst, dwarfing all cell signals in the frequency range.
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.
Turn OFF the 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 experience a "denial-of-service." 1933key's cell phone jammers are often referred to as mobile phone blockers, cell jammers, frequency disrupters, cellular immobilizers, and handset zappers.
Video background:
The model used in this video effectively jams up to 30 meters in diameter. A high-powered Radio Frequency Spectrum Analyzer, such as Tektronix's SA2600, picks up frequencies and measures the signal strength of a defined proximity. The spectrum analyzer surveys the radio frequency spectrum, mapping received signal strength and resolves spectral interference origins.
We set the signal detection spectrum for 1800MHz, with span interval of 20MHz. This live test was conducted in the heart of an exhibition showcasing cellular to PC mapping technologies, wireless networking and RFiD readers and tags. In the exhibition hall, cellular signals measured indicated normal cellular usage. Upon turning on 1933key's J15P01B Portable 30m Cellular Jammer and Mobile Phone Blocker, all cellular signals in the 1800MHz frequency range are visibly dwarfed and absorbed, rendering that frequency useless in the jammer's proximity. When the Spectrum Analyzer is set to monitor 800MHz, the same effect takes place.
Product background: Model J15P01A (800 + 1900 MHz) for North, Central & South American Cellular Systems Model J15P01B (900 + 1800 MHz) for European, Asian, Middle Eastern & African Cellular Systems Both models effective range up to 30 meter diameter - 15 meter radius.
Notes: * The J15P01 represents 1933key's entry level jammer. Other 1933key cell phone jammers jam up to 50 and even 120 meters in diameter.
