Built-in Directional Power Adjustable High-Power 5G Mobile Phone Signal Jammer
X12D Suitable for signal-blocking environments such as college entrance exams, CET-4/6 exams, bar exams, and government conference rooms.

Full-band mobile coverage
X12D is the nemesis of wireless cheating devices such as mobile phones, Wi-Fi, Bluetooth, and electronic watches. It serves as the security guardian and purification expert for confidential venues and standardized examination halls.
This jammer is a directional, full-band communication signal blocker, representing the seventh generation of eco-friendly signal jammers. It exclusively blocks the reception of mobile devices at the site, causing no impact whatsoever on surrounding base stations.
High-power
All models in this series employ channelized output, with individual transmitter power not exceeding 120W and each channel output ranging from 5W to 10W.
The X12D device utilizes a directional antenna array, significantly extending its effective jamming range. It blocks all mobile phone signals within 8 to 50 meters (depending on base station signal strength), completely severing communication between all mobile devices within the jamming zone and the outside world.
X12D Features
1. Effectively shields GSM/CDMA/DCS/WCDMA/LTE/Wi-Fi (tri-band)/5G (broadcast 5G) and other frequency bands;
2. Built-in dual switching power supply and high-performance aluminum alloy heat sink ensure excellent short-term operational stability;
3. Features six silent cooling fans.
4. Utilizes advanced foreign chips and technology with soft-start circuit design for high integration;
5. Employs ultra-high-frequency interference technology; waterproof design enables indoor/outdoor use.
6. Features multi-channel segmented independent shielding technology for enhanced effectiveness;
7. Manual switch controls operation with effective shielding range of 8m-100m (depending on carrier network signal strength);
8. Capable of extended uninterrupted operation;
9. Interference frequency bands expandable per user requirements;
10. Primary application scenarios:
11. Confidential meeting venues in government agencies, enterprises, etc.;
12. Courts, detention centers, and prisons of all sizes;
Any location prohibiting mobile phone
