FAQS
1. How can we ensure product quality and long-term stability?
All systems undergo RF testing, aging tests, temperature tests, and continuous operation verification before shipment.
Industrial-grade components are used to support stable long-term operation in demanding environments.
2. Can you send samples before bulk orders?
Yes. Sample units are available for testing and project evaluation before mass procurement.
For customized projects, sample preparation may require additional engineering verification time.
3. What is the Typical Production Lead Time?
Production time depends on configuration complexity and order quantity.
Standard models: 7–10 working days
Customized systems: 2–4 weeks
Large integrated projects: depends on technical requirements
Urgent deployment projects can be prioritized upon request.
4. What if the device does not perform well in our region?
Wireless environments vary significantly between countries, operators, and building structures.
Before production, we confirm local communication specifications and application scenarios to improve compatibility and operational effectiveness.
⚠️ WARNING: Incorrect configuration parameters may reduce overall performance.
5. How do you protect confidential projects and customer information?
We strictly protect customer project data, deployment information, and technical specifications.
NDA agreements are supported for enterprise, infrastructure, and professional security-related projects.
6. What if items are damaged during shipping?
All equipment is packaged with reinforced industrial export protection.
If shipping damage occurs, we provide technical assistance, replacement components, or replacement units according to warranty terms.
7. What frequency bands can your products disrupt? Does it support 5G?
Our devices support full-spectrum blocking, 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.
8. 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 blocking radius (preventing unwanted overspill)
-
Enhancing specific bands with strong external interference
-
Reducing noise and power consumption while improving system stability
9. 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.
10. Will the cell phone inhibitors 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.
11. Can I adjust the power output of each frequency?
Yes. Each frequency module can be independently adjusted to control the blocking distance (e.g., 8–100 meters) based on your actual environment.
12. Will multiple omnidirectional inhibitors interfere with each other?
No, if properly installed. We provide optimized layout and directional separation to avoid overlap or interference between units.
13. 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.
14. 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.
15. Do your signal inhibitor support 24/7 operation? Is it prone to overheating?
Yes. Our inhibitors 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.
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.
