Why Choose Us
The phone blocker effectively blocks all wireless communication signals within the exam environment. By transmitting controlled electromagnetic interference signals across designated frequency bands, it establishes a localized electromagnetic isolation zone. Within this zone, wireless devices such as mobile phones, tablets, and smartwatches are unable to establish connections with external communication networks. This ensures information security and fairness during examinations, making it an essential safeguard for standardized testing environments.
For examination environments with complex signal conditions—such as those near base stations or within reinforced buildings—we offer high-power, adjustable blocking solutions. The system supports precise power＆frequency regulation, multi-channel frequency control, and customized antenna configurations to achieve uniform field strength and full-area coverage. Even under high-signal interference or multi-network overlap, the solution maintains stable and reliable shielding performance, ensuring comprehensive protection against wireless communication and cheating attempts.
Our phone blockers provide full-spectrum interference coverage, effectively blocking mobile communication signals across 2G, 3G, 4G, and 5G networks (including broadcast 5G), as well as wireless communication channels such as walkie-talkies. It also disrupts Bluetooth, Wi-Fi, and wireless transmission signals used by covert earpieces, bone-conduction headsets, and other connected devices.
Our Omnidirectional signal blockers ensure complete 360° coverage in exam rooms, effectively blocking mobile phones, wireless headsets, and all other devices. By eliminating any chance of external communication, they safeguard exam integrity and fairness, providing a secure, distraction-free environment where every student can focus fully on their tests.
Equipped with a built-in aluminum alloy radiator and six fans, the device delivers stable operation, superior heat management, and exceptionally long-lasting durability.
It provides a comprehensive solution to block communication signals from various wireless devices, such as drones, remote-controlled toys, walkie-talkies, mobile phones, and Wi-Fi devices, within the frequency range of 20–6000 MHz.
These blockers neutralize IED triggers, ensuring personnel and mission safety in hostile zones.
We needed a reliable solution to block unauthorized communications used by inmates to smuggle contraband or coordinate escapes and to prevent sensitive information leaks during meetings. This signal blocker exceeded our expectations! Not only is it high-powered, but it also allows precise adjustment of power and frequency. Its unobtrusive design delivers exceptional effectiveness. Once activated, there are no signal blind spots and no risk of information leaks—exactly what we needed for enhancing prison security.
We installed this signal blocker throughout our prison, and it immediately enhanced our security measures. Its precise, adjustable power settings let us customize coverage exactly where it’s needed. By blocking all mobile and wireless signals, we have effectively reduced the risks of attacks and violence. It has become an indispensable tool for protecting the integrity of our facility.
As a prison security officer, I had doubts at first about how effective the signal blocker could be.However, this high-power phone blocker has exceeded all my expectations. Even near strong cellular base stations, it consistently maintains full effectiveness. It’s perfect for supporting comprehensive, multi-layered security protocols. Truly a professional-grade solution tailored for correctional facility security.
