Phone Jammer Module

This cellular jammer module supports full-band mobile phone signal jamming, covering 2G, 3G, 4G and 5G wide cellular bands for comprehensive suppression. It fully blocks nearby mobile functions including voice calls, SMS, and cellular data access. In high-security scenarios such as confidential meetings, exam venues, and military restricted areas, it prevents secret recording, hidden photography, real-time transmission, and leakage of sensitive content.
