Product Short Description

The device is designed to restrict the use of mobile communications in rooms where it is prohibited or undesirable. And also in places where silence is required or confidential negotiations are underway.

Used to protect information.

Effectively blocks the work of eavesdropping devices based on mobile communications.



The frequencies are adapted to the main standards of mobile communication and data transmission.
The device has minimal dimensions and built-in antennas.
Opening hours are unlimited.
Has independent adjustment of the output power of each mobile communication standard.
Range – for satellite range – 30 meters, mobile ranges – within
perimeter of the car. Indoors – up to 100 sq. m. The efficiency can be higher / lower, depending on
deleting the base station.
The small dimensions of the device make it possible to use it as a universal automobile
anti-tracker for all standards of mobile communication and navigation. Blocks the work of any unknown tracker with a 99.666% probability. Also blocks the work of eavesdropping GSM / 3G / 4G / LTE / WI-FI – microphones, GSM / GPS trackers with a built-in microphone and a SIM card.

– blocking of all navigation frequencies – any tracking trackers, location determination on smartphones
– portable use (external battery)
– the ability to use in a car, powered by a cigarette lighter through an adapter
