OEM ODM Mobile Communication Jammer for Examination Halls and Libraries with Adjustable Radius

Mobile signal jammers are essential devices designed to block cellular communications in areas where mobile phone usage poses risks or disruptions. These devices transmit powerful radio signals that interrupt the connection between mobile phones and base stations, effectively disabling phones within the jamming range. When activated, idle phones display "NO SERVICE," and incoming calls are blocked as if the phone is turned off. Once deactivated, normal service resumes automatically.

Constructed with an aluminum-alloy casing rated IP65, this jammer offers high resistance to dust, water, and corrosion, ensuring durability in various environments. It utilizes special technology to prevent interference between frequency bands and specifically targets the downlink frequency of mobile systems without disrupting base station operations. The broadband segment covers all wireless signals, including 2G, 3G, 4G, and 5G, making it versatile for multiple applications.

Equipped with a built-in directional antenna and high-performance heat sink, the device supports long-term use and easy installation. It is suitable for indoor wall mounting and operates within a temperature range of -10 to +60°C. Applications include gas stations to prevent fire hazards, government conference rooms to avoid secret leakage, examination halls to prevent cheating, and public spaces like libraries and cinemas to maintain silence.
