Functions & Advantages
Comprehensive Signal Shielding
The VS-X11 effectively shields a wide spectrum of signals, including dual-mode 2G, 3G, 4G, 5G mobile phone signals, GPS positioning signals, and 2.4G/5.2G/5.8G WIFI signals. This all-in-one shielding capability ensures that no external communication or positioning services can function within the designated range, completely isolating the area from external information transmission.
High-Gain Built-In Antenna
Equipped with a built-in high-gain antenna, the device significantly enhances signal coverage power and stability. Unlike traditional jammers with external antennas (which are prone to damage and signal loss), the integrated design of the VS-X11's antenna not only improves its durability but also ensures uniform signal distribution within the shielding range, avoiding "shielding blind spots".
Base Station-Friendly Design
A key advantage of the VS-X11 is its ability to only shield the reception of effective signals within the target range without causing any interference to surrounding operators' base stations. This means the device protects the security and quietness of the designated area while not disrupting normal communication services for users outside the shielding range-a critical feature for compliance with telecommunications regulations.
Imported Chips for Enhanced Efficiency
The use of high-quality imported chips in the VS-X11 ensures higher energy efficiency and more stable performance. These chips optimize signal jamming precision, reducing unnecessary power consumption while maintaining strong shielding capability. Even in environments with increasingly strong base station signals, the device can still achieve the optimal shielding distance through multiple rounds of experimental verification.
Flexible Control Modes
Main Power Switch: The device is equipped with a physical main power switch for direct on/off control, ensuring simple and reliable operation.
Remote Control Switch (Optional): For added convenience, a customized remote control is available as an optional accessory. Users can turn the device on or off from a distance, eliminating the need for direct contact-ideal for large spaces or hard-to-reach installation locations.
24/7 Stable Operation
With a built-in 24V power supply and a robust circuit design, the VS-X11 can operate continuously for 24 hours without performance degradation. This makes it suitable for scenarios that require long-term shielding, such as 24-hour confidential business offices and continuous exam venues.
Shielding Range & Performance
The effective shielding range of the VS-X11 is 5-10 meters in radius, but this may vary slightly depending on the strength of the surrounding base station signals:
In areas with weak base station signals (e.g., remote rural areas or indoor spaces far from base stations), the shielding range may extend beyond 10 meters.
In areas with strong base station signals (e.g., urban centers or locations within 500 meters of a base station tower, where the signal field strength reaches -50dBM), the shielding range may be reduced to 5 meters or slightly less.
To ensure optimal performance, we recommend conducting a site survey before installation to determine the best placement based on local signal conditions.
Application Scenarios
The VS-X11 is designed to meet the security and order needs of various professional environments, including but not limited to:
Conference Rooms: Prevents information leakage through mobile phones or WIFI-connected devices during confidential meetings.
Classrooms & Exam Venues: Eliminates cheating via mobile phones, GPS trackers, or WIFI signals, ensuring fair and orderly exams (especially suitable for college entrance exams, professional qualification exams, etc.).
Confidential Business Areas: Protects sensitive information in corporate headquarters, R&D centers, and high-security business departments by isolating external signals.
Hospitals (Certain Areas): Shields mobile phone and WIFI signals in operating rooms or intensive care units (ICUs) to avoid interference with medical equipment (note: consultation with hospital IT and medical staff is required to ensure no impact on critical devices).

Installation Methods
The VS-X11 supports two installation methods to adapt to different usage needs:
Temporary Use (Tabletop Placement)
For short-term scenarios (e.g., one-time exams, temporary meetings), simply place the jammer host on a flat, stable tabletop. Ensure:
The tabletop is at least 50cm away from walls or metal objects (to avoid signal reflection affecting shielding performance).
The device is not covered by any objects (e.g., cloth, paper) to prevent overheating.
Fixed Use (Wall Mounting)
For long-term scenarios (e.g., permanent confidential business offices, fixed exam venues), mount the device on a wall using the built-in mounting holes (installation hardware not included; please use hardware suitable for the wall material). The recommended installation height is 180-250cm above the ground-this height ensures that the signal covers the entire space evenly, as most communication devices (mobile phones, tablets) are used at waist to shoulder height.
Operation Steps
Power Connection: Connect the power cord to the device's power interface and plug the other end into a standard AC 220V power outlet.
Power-On:
Using the main power switch: Flip the switch to the "ON" position. The power indicator light will turn on, and the device will start operating after a 1-2 second delay (due to the power-on protection circuit).
Using the remote control (optional): Press the "ON" button on the remote control. The power indicator light will confirm activation, and the device will start working.
Power-Off:
Using the main power switch: Flip the switch to the "OFF" position. The power indicator light will turn off, and the device will stop operating immediately.
