CELLULAR COMMUNICATION AND WIRELESS ACCESS BLOCKER "KALMAR"

CELLULAR AND WIRELESS ACCESS BLOCKER "KALMAR"

General information and purpose of the device
The intelligent multi-blocker "Kalmar" is designed to suppress cellular and wireless communication signals of CDMA450, GSM, UMTS (3G), LTE (4G), WiFi, BlueTooth, ZigBee standards in order to prevent information leakage due to unauthorized use of mobile devices and to create comfortable conditions for negotiations.

The blocker belongs to the new generation of devices. A distinctive feature is the use of adaptive interference. This type of interference allows achieving a high probability of suppression with minimal radiation into the air. (Figure 1)
Due to the similar structure, the interference signal is perceived by the mobile device as a base station signal and passes all filtering systems up to decoding of information. This method allows you to effectively block the operation of mobile devices that support broadband communication standards.

Functional capabilities
The device provides reliable suppression at a distance of up to 15 m.
It is possible to connect the device to a PC. Using the included software "Squid", it is possible to control the load of the radio frequency spectrum, control the power and type of interference.

Advantages of the "Squid" blocker
Forms adaptive interference. This type of interference allows achieving a high probability of suppression with minimal radiation into the air;
Blocking is carried out in all frequency ranges of wireless and cellular communications relevant for 2017. It is possible to modify for new ranges;
All antennas of the device are planar, located inside the case, the power supply is also built-in. This significantly increases the "survivability" of the device;
Aesthetically verified design. Available in black and white, in a tabletop and wall version;
Connection to a personal computer is provided for fine-tuning the suppression parameters for specific operating conditions;
The Kalmar blocker is permitted to be placed in designated areas of the second and third categories.
