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.
