Example of a mobile phone jammer, produced by Jammerspro. A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting ...
Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3] The concept can be used in wireless data networks to disrupt information flow. [4]
Sweep jamming is a modification of spot jamming where the jammer's full power is shifted from one frequency to another. While this has the advantage of being able to jam multiple frequencies in quick succession, it does not affect them all at the same time, and thus limits the effectiveness of this type of jamming.
In passive mode, the StingRay operates either as a digital analyzer, which receives and analyzes signals being transmitted by cellular devices and/or wireless carrier cell sites or as a radio jamming device, which transmits signals that block communications between cellular devices and wireless carrier cell sites.
The jamming system is easily controlled and the failures are easily diagnosed. It is controlled on the front panel. The operator can switch on/off particular transmitting systems and subsystems, set up to three jamming sub-bands in each. Dwell time in each sub-band can also be modified. Jammer is equipped with IP, RS 485 and USB interface.
