Cellular jammers

Cellular jammers are designed to suppress unauthorized data retrieval equipment operating in mobile network standards, Bluetooth or WiFi. Their operation is based on generating noise interference in the required frequency band. Besides, they enable gradual adjustment of the interference signal power in all the bands, which facilitates blocking of wireless communication standards within the protected room only.
