120W Adjustable N-14 Directional Cell Phone Signal Blocker 2/3/4/5G/WIFI/GPS/Bluetooth Wifi Blocker

Do you have to put a lot of effort into managing these issues?

One inmate uses it to coordinate an escape, timing every move with outside accomplices.
Another directs drug trafficking routes, laundering money while serving time.
Every illegal call undermines security, endangers your staff, and extends criminal influence into the prison areas we are sworn to protect.

If so—it's time to act. Our cell phone blockers can block 2G/3G/4G/5G, Wi-Fi 2.4G/5.8G, GPS L1–L5, Bluetooth, UHF/VHF, LORA and LOJACK with 8-100M jamming distance. Featuring a built-in, directional, power-adjustable design, this high-power 5G mobile phone signal blocker precisely targets only on-site devices, ensuring surrounding base stations remain unaffected—ideal for maintaining prison order and security and protecting confidential meetings.

Specific bands can be customized according to your application requirements. Don’t wait until a critical leak happens

FAQS

1. What frequency bands can your products block? Does it support 5G?
Our devices support full-spectrum jamming, including 2G/3G/4G/5G, Wi-Fi 2.4G/5.8G, GPS L1–L5, Bluetooth, UHF/VHF, LoRa, etc. Specific bands can be customized according to your application requirements.

2. Can output power be adjusted individually per band? Why is this important?
Yes. Each frequency module supports independent power adjustment. This allows for:

• Accurate control of the jamming radius (preventing unwanted overspill)

• Enhancing specific bands with strong external interference

• Reducing noise and power consumption while improving system stability

3. Is it effective in high-signal environments (e.g., <200 meters from cell towers)?
Absolutely. Featuring built-in high-power directional RF modules and high-gain antennas, our blockers remain effective even under extreme interference levels from nearby base stations.

4. Will the signal blocker affect other electronic equipment, like projectors or microphones?
No. Our signal blockers only target wireless communication frequencies (e.g., mobile, WiFi, GPS). They won’t affect wired audio-visual equipment.

5. Can I adjust the power output of each frequency?
Yes. Each frequency module can be independently adjusted to control the jamming distance (e.g., 8–100 meters) based on your actual environment.

6. Will multiple omnidirectional blockers interfere with each other?
No, if properly installed. We provide optimized layout and directional separation to avoid overlap or interference between units.

7. Do I need to install any equipment outside the room?
Usually not. But in extreme environments (e.g., near strong outdoor base stations), we may recommend an outdoor blocking unit to strengthen coverage from both sides.

8. Does installation require damaging the building structure? Can the layout be flexible?
No structural damage is needed. The blocker can be mounted on walls, ceilings, or pillars. Recommended installation height is 2.5–3 meters, and the layout is fully adaptable to your site conditions.

9. Can the device operate 24/7? Is it prone to overheating?
Yes. Our blockers support continuous 24/7 operation and are equipped with 6-zone fan cooling and soft-start circuitry for stable long-term performance without freezing or overheating.

10. Do you support OEM/ODM? Can the device be customized for specific scenarios?
Yes. With over 21 years of OEM/ODM experience, we can customize power levels, frequency bands, housing structure, and communication protocols for conference rooms, prisons, military sites, vehicles, and more.
