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.
