High-performance mobile phone signal jammer and 5G network jammer

This equipment employs internationally leading signal jamming algorithms and a high-gain multi-channel transmission system, capable of accurately locking onto and blocking mobile phone signal transmission channels, achieving efficient interception of various communication formats (including voice, SMS, and data transmission). Its core module uses dynamic frequency scanning technology to detect the surrounding signal environment in real time and responds to the jamming target within milliseconds, ensuring stable jamming effects and wide coverage. Whether in conference rooms, examination rooms, prisons, or confidential units, it can achieve comprehensive control over illegal or unnecessary communications.

This device integrates a multi-band transmission module, capable of simultaneously shielding 2G, 3G, 4G, and 5G signals, covering all frequency ranges of mainstream telecommunications operators. Its efficient signal coupling and intelligent allocation system avoids energy waste caused by frequency band overlap, achieving maximum interference coverage. Users can choose to enable or disable specific frequency bands according to actual needs, flexibly adapting to different application scenarios, such as meeting confidentiality, military and police law enforcement, exam cheating prevention, and information security protection.

The device has a built-in high-capacity lithium battery, allowing it to operate independently without an external power source. This makes it particularly suitable for temporary and mobile applications, such as impromptu meetings, on-site inspections, and vehicle-mounted deployment. The battery features intelligent power management, displaying its status via LEDs and supporting simultaneous charging and use. It ensures continuous and stable signal jamming operation in both indoor and outdoor environments.

This jammer employs a high-efficiency RF amplifier module and an intelligent temperature control system, significantly reducing energy consumption and heat buildup. The low-power circuit design not only reduces battery consumption but also extends the overall lifespan of the device. The aluminum alloy casing and multiple heat dissipation channels ensure stable performance and safe temperature even during extended operation. This design makes it a high-end signal jamming solution that balances performance, battery life, and portability.
