FAQ
How does a signal jammer work?
Signal jammers disrupt normal communication between mobile phones and base stations by transmitting interference signals on the same frequency bands. Our device uses intelligent scanning technology to block only designated frequency bands, ensuring other electronic devices remain unaffected.
What is the effective range of the jammer?
Effective range depends on multiple factors, including power class, signal strength, and environmental conditions. Handheld devices typically cover 5-15 meters, desktop devices 10-30 meters, and high-power devices can reach over 50 meters. We'll recommend the right product for your specific use case.
How to properly install and use a signal jammer?
1. Place the device at the center of the area to be shielded. 2. Ensure a stable power connection. 3. After powering on, wait 1–2 minutes for optimal performance. 4. Adjust the power level as needed. For detailed instructions, refer to the product manual.
Does the device need to run for 24 hours?
Depends on the use case. For exam halls and conference rooms, enable as needed. For prisons and secure rooms, we recommend 24-hour continuous operation. Our devices are designed for long-term, uninterrupted running.
How do I maintain the device?
1. Regularly clean dust from the device surface. 2. Ensure adequate ventilation to prevent overheating. 3. Check power supply and connection cables. 4. Schedule a professional inspection every six months. Under normal use, the device lifespan is 5–8 years.
Is using a signal jammer legal?
Signal jammers are restricted to authorized entities, including educational institutions (exam centers), judicial bodies (courts/prisons/border checkpoints), and military/confidential units. Deployment requires approval from local public security and radio administration authorities.
