The Cell Phone Jammer Story

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 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.

* Cellular Phone Jammers MAY NOT be legally Marketed or Sold to all interested citizens within USA, Canada, and many European nations. In some countries, average non-government employed citizens may NOT lawfully purchase Jammers -- in which case -- are NOT to consider 1933key Jammers as being available for promotion or purchase.

* Such Jammers ARE in use however by citizens affiliated with such organizations as the U.S. Department of Defense, U.S. Central Intelligence Agency, U.S. Federal Bureau of Investigation, U.S. Secret Service, U.S. Drug Enforcement Agency, U.S. National Security Agency; and by thousands of Law Enforcement employees all across USA.

* If you're not under legal restraints of applicable legislation in your country (i.e. authorized government-related customer), send your jammer requests today. Otherwise, send your inquiry of consideration to: c o n t a c t @ 1 9 3 3 k e y . c o m

Two posers recently claimed the FOX Newscast about FBI Tapping Cell Phones is fake, from the movie Eagle Eye:

Kudos for having a good ear, but in the 8th minute of the Eagle Eye movie there is a fake duplicate of the same December 2006 FOX newscast about FBI tapping cell phones. The movie version has a female broadcaster with a fake non-affiliated news screen and no channel logo speaking an edited and version of the same story.

Thanks for the heads up, nubs and all. Proved interesting though.

i miss the days before cell phones was invented

[razorflown2]

Ya, back in the day, we used to take 900mhz phones, and turn them on, then drive away from their base station and around town till we picked up someones call. It was great, we could talk to them, fuck with them.

@irishgeoff1 not trying to be mean but holy crap your every were calm down about ur tapper zapper

[HurricaneSondra]

i thought that once the phone is off, it can not radiate rf energy! maybe the gps is differant, but the phone i thought could not be activated from far out when it is off. i gotta think about that more i guess.

[AskHack]

They can track it with the battery out as well.

[cidland]

Search youtube for "phone detracktor" for a solution to cell phone spying, hacking, eavesdropping, stalking and tracking.

[razorflown2]

@kthapar01 no idea, i would assume so

[TheJammerall]

it is really cool, i bought one two days ago, it helps me a lot

[irishgeoff1]

I love my yapper zapper phone blocker

[jacobg1777]

@MrJRamal Does it really bother you that much?

[steve001968]

@2204Alpha You wouldn't have humans listening on large scale telephone intercepts you would have computers monitoring for keywords and recording only conversations with target keywords in them or to insure you get the entire conversation you would record all monitored conversations until the conversation ends without a keyword spoken at which point that particular conversation is deleted and the storage space is reclaimed. If a keyword is spoken the conversation would not be deleted.
