In an era where digital infiltration and advanced espionage techniques are constantly evolving, the physical security of sensitive facilities has become a critical concern—especially for government and military confidential meeting rooms. To prevent severe consequences resulting from information leaks, it is essential to deploy cell phone jammers within controlled environments.

A client required a complete communication signal jammer within a 300-square-meter meeting room used for confidential briefings.

The challenge, however, was the extremely harsh electromagnetic environment. The room was located in a dense urban area, surrounded by residential buildings and commercial towers, with several cell towers positioned within a 200-meter radius. Additionally, signal boosters were installed on nearby rooftops, pushing the mobile signal strength to RSRP levels as high as -50 dBm. Under such strong signal interference, conventional jammers were ineffective.

During confidential meetings, the cell phone jammers effectively disrupted real-time transmissions from hidden cameras and covert listening devices. This comprehensive interference capability played a critical role in protecting highly sensitive information—such as classified military intelligence, national security strategies, emergency response plans, and major project investment discussions.

In an age of invisible data leaks and AI-enhanced espionage, even a brief breach can compromise military intelligence, derail national defense strategies, or expose critical emergency plans. The cost of such exposure is not just operational failure but a national crisis.

It is urgent to adapt high-power blockers in modern cities, where high signal density renders traditional jammers obsolete. Dexinkang’s customized solution delivered robust performance in an extreme environment, ensuring absolute confidentiality in mission-critical settings.
