The SHIELDK RF Signal Jamming Series is a security solution designed to control wireless communication signals within designated areas, helping to minimize the risks of unauthorized communications, wireless eavesdropping, and information leakage. It is ideal for environments where wireless communication control is essential, including government agencies, defense facilities, correctional facilities, research laboratories, and other critical security areas.
BK-JAMMER 601
K-JAMMER 601 is a fixed RF signal jamming system designed to control 2G, 3G, 4G, 5G, and Wi-Fi communication bands. Equipped with a directional antenna, it provides precise signal control within designated areas and can be customized to meet specific installation environments and operational requirements.
As the use of smartphones, Wi-Fi, and wireless data communications continues to grow rapidly, the risks of information leakage and unauthorized wireless communications within secure areas are also increasing.
To strengthen security, critical facilities require effective measures to block unauthorized wireless communications within protected areas.
Unauthorized Communication Prevention System (RF Signal Jammer)
The system emits RF jamming signals to disrupt wireless communications within a designated area, helping to prevent the unauthorized use of mobile communication devices.
By controlling wireless signals within the protected area, it helps prevent unauthorized voice communications, Wi-Fi connections, wireless eavesdropping, and mobile data communications.
Built-in Directional Antenna – Clean exterior design with no protruding antennas
Precision Targeted Coverage – Jams only the designated area without affecting communications outside the building
IP65 Protection – Suitable for both indoor and outdoor restricted-access areas
Modular Design – Customizable to meet country-specific frequency requirements
Downlink-Only Jamming – No interference with base stations and silent operation
Automatic Protection Circuit – Protects against overheating, over-output, and high VSWR
PERFORMANCE
Blocks all mobile phone communications within a designated area. By adjusting the blocked frequency bands, it does not interfere with mobile phone use outside the building.
Enables long-range jamming with high-efficiency output. Built-in self-protection functions prevent damage by automatically shutting down the device in the event of overheating or output overload.
OPERATION
Easy to operate and install. The modular design allows each module to operate independently.
Simple to use through direct power switch ON/OFF control or remote control operation.
ANTENNA
Built-in antenna allows easy installation, and the directional antenna can block only the desired area.
Blocks target radio signals without affecting cellular base stations.
With a built-in directional antenna, the device has no protruding antennas like other products, giving it a clean and simple appearance.
NOISE
Operates without noise even in quiet environments, making it difficult to detect from the outside.
WATERPROOF / PRACTICALITY
Designed for practical use, from portable applications to waterproof outdoor deployment, allowing it to blend naturally into any location.
Key Applications
Government Agencies (Secure Workspaces)
Military Facilities (Secure Zones)
Corporate Security Areas (Information Protection)
Correctional Facilities (Unauthorized Communication Prevention)
Critical National Infrastructure (Critical Infrastructure Protection)
Airports & Public Facilities (Security Control)

Necessity of RF Jammer Installation
Fundamental preventive measures are required to prevent significant social and economic damage caused by illegal calls, text messages, and SNS transmissions.
Measures are needed to prevent the leakage of policy meeting contents from national and public institutions.
RF jammers can restrict unauthorized communication using mobile communication devices, such as mobile phones, within controlled areas.
In an era of global competition, protection against the leakage of corporate secrets by competing companies is required.
Preventive measures are needed to protect personal privacy.
Measures are required to eliminate unnecessary noise and disturbances in public places.
RF signal jamming products may be subject to different regulations and applicable frequency bands depending on the laws and frequency environment of each country. Before deployment, it is recommended to review the applicable regulations, installation environment, and intended country of use.
