Killer CDMA GSM Network Disruptors

Cell phone jammer are devices used to prevent and block cellular signals, primarily in mobile phones. They’re often used to disrupt signals in locations where silence is expected or where using a phone would be impolite or rude. Nowadays, such products are increasingly used in public places

Phone jamming is about to get political. Everyone from police to governments are using simple devices that prevent people from making calls or texting in certain areas — and they're doing it to control the flow of information. Let's take a look at these devices, their current uses.

In the United States and South America, most digital mobile phones operate on a a 1.9 GHz frequency band, while 900 Mhz and 1.8 GHz bands are used across most of Europe and Asia. Even if your phone operates on multiple bands, manipulation of a single band is enough to cause a call to fail by disturbing the outgoing call or incoming voice data.

Cell phones are commonly used in prisons, however, the items are illegal in U.S. Federal prisons. GSM jammer are used by prisons to block calls, preventing coordination of gang related activities within the prison and preventing unauthorized communication with the outside world.

CDMA disruptor also play a role in providing security during transportation of high level officials. U.S. Presidential motorcades make use of the devices, and a cell phone jammer played a role in foiling a 2003 assassination attempt on Pakistani President Musharraf. Cell phones are common triggers in improvised explosive devices, with jammers sometimes preventing detonation.

In France and Japan, use of GSM jammers is legal in movie theaters, art galleries, concerts, and other public venues.
