Overview

No Signals. No Cheating. No Compromise

By deploying classroom cell phone blockers, schools can instantly block calls, texts, and data connections—eliminating cheating methods, hidden devices, and unauthorized communication, while creating a secure, distraction-free, and fair examination environment.
Our portable cell phone blockers are plug-and-play devices—just switches, an indicator light, and built-in antennas. Advanced cellular blockers allow adjustable range control, ensuring coverage is limited to the classroom without affecting neighboring areas.

FAQs

  1. Is the omnidirectional signal blocker effective in high-signal environments (e.g., near mobile towers)?
    Yes, even in areas with strong external signals, such as near mobile towers, our omnidirectional blocker ensures reliable performance due to its high-power RF modules and high-gain antennas, effectively maintaining a fair examination environment free from external interferences.
  2. Will the signal blocker interfere with other electronic devices like projectors or microphones?
    No, the blocker only affects wireless communication signals (mobile, Wi-Fi, Bluetooth, GPS) and does not interfere with wired devices such as projectors, printers, or classroom sound systems, ensuring normal teaching and exam operations.
  3. Can I adjust the jamming range for my examination hall?
    Yes, the jamming range is adjustable from 1m to 30m, allowing for precise coverage of exam halls of different sizes without affecting nearby classrooms or office areas.
  4. Will multiple omnidirectional blockers interfere with each other in a large examination hall?
    No, with proper placement, multiple blockers will not interfere with each other. We provide layout recommendations to ensure that each unit works seamlessly without overlap or signal leakage, maintaining the integrity of the exam environment.
  5. Do I need to install additional equipment outside the examination building for full coverage?
    Typically no additional equipment is needed. However, in schools located near mobile towers or areas with strong external signals, an outdoor unit can be added to strengthen coverage and prevent unauthorized communications from penetrating the exam halls.
  6. Does installation require modifying the classroom structure?
    No, our devices are flexible in installation. They can be wall-mounted, ceiling-mounted, or placed on any flat surface without any structural modifications, making them easy to integrate into school facilities.
  7. Can the device run continuously without overheating during long exam sessions?
    Yes, the system supports continuous operation with built-in cooling systems and soft-start circuits, ensuring stable 24/7 operation throughout exam periods without cheatiing risks.
  8. Do you offer customization for school examination needs?
    Yes, we provide OEM/ODM services to tailor power levels, frequency bands, and housing designs to fit specific school requirements, ensuring exam fairness and confidentiality according to your institution’s needs.
