The device is designed for jamming of 
mobile phones and wireless access channels of all the existing standards, as well as for surpassing of any detected sources of unauthorized radio emissions. An operator can change a signal for jamming from a set of standard blocking signals (profiles), or synthesize blocked signal by his own discretion. If the jammer works together with a monitoring receiver, the blocking signal is turned on automatically after detection of the corresponding subscriber’s signal, or after analysis in the computer of the radio receiving device of the detected unauthorized signal. The jammer can be used for blocking of drones.
