Customer FAQ
Q1: Will this 4 band wireless signal control device affect nearby public base stations?
No. This device uses advanced base station protection technology to control only specific frequency bands within a set range. Once the mobile terminal leaves the shielding area (e.g.,
When you exit the conference room, the signal will automatically restore without interfering with outdoor or distant public communication base stations.
Q2: Why does the actual shielding distance of the device vary?
A: The effective shielding radius (10-150 m) is a dynamic range primarily determined by the signal strength at the installation site. If the site is very close to the base station or signal penetration
Stronger signal reduces the effective shielding range; conversely, in areas with weaker signals, shielding is more effective. We recommend testing the signal on-site before use.
Q3: Can this desktop signal jammer operate continuously for extended periods?
A: Yes. BCSK-D-G-4KT is designed for industrial-grade applications, featuring imported Murata ICs from Japan and a metal aluminum enclosure for enhanced heat dissipation, paired with high-performanceSwitching Power Supply, Design Label
Ready is Support365 consecutive days of workIdeal for secure environments or exam rooms requiring long-term monitoring.
Q4: Is the device harmful to humans during operation?
A: Please use with confidence. This product has passedGuangdong Province Occupational Health and Radiation InspectionAll radiation indicators comply with national safety standards. Its emission power is maintained within safe limits.
inside, it has no negative impact on human health.
Q5: If I need to block a large range, is one device enough?
A: The effective range of a single device typically spans 10–150 meters. If your deployment area is large or contains many walls, please consult us based on the site floor plan.
