Some candidates used mobile phones and other high-tech tools to cheat during the test, some terrorists and hostiles would use mobile phones to remotely control bombs, and the fact that the criminal's mobile phone number has become a criminal tool has affected social stability. Jammer-mart has developed a mobile phone signal jammer that can effectively solve the above problems. New products formed by specific electromagnetic signals at specific locations to protect base stations so that mobile phones cannot receive data, and interfere with mobile phones and thereby eliminate many negative effects.
The good heat dissipation effect effectively solves the phone signal interference of the 3G / 4G jammer, and it can be used for a long time without worrying about damaging the device. Information security product developers use modern high technology, analyze the communication mechanism in detail, comprehensively compare the methods of suppressing electromagnetic radiation, and have complete independent intellectual property rights. The mobile phone signal blocker can form a protective electromagnetic field around you, effectively prevent blocking the mobile phone network and prevent mobile phone information from leaking.
The mobile phone interference device must be installed in a well-ventilated place to avoid blocking large objects receiving signals from the mobile phone, avoid strong heat sources with strong electromagnetic sources, and ensure shielding effects and long-term stable operation. When the jammer is activated, you cannot stack other items around it. When not using the jammer device, please turn off the power to avoid affecting the normal use of the phone. When using a protective cover outdoors, be careful not to get water.
