Introduction:
The Mobile phone Signal Jammer system
Mobile phones work in a certain frequency range, mobile phones and base stations are connected by radio waves, and transmit data and voice with certain baud rate and modulation mode. In response to this communication principle, the cell phone signal shield is scanned at the low end of the channel at a certain speed in the working process. The scanning speed can generate random code interference in the receiving message of mobile phone. The mobile phone can’t detect the normal data sent from the base station, so that the cell phone can’t establish connection with the base station. Mobile phone performance is the phenomenon of search network, no signal, no service system and so on.
The Waterproof Adjustable High Power Phone Jammer for Prison is specially customized to accommodate a fully integrated broad band jamming system which provides the ultimate solution for Prison Military and Police convoys or VIP protection. The modules are controlled separately and they also can work simultaneously.
Each module with antenna can be used as a single jammer. The prison jammer is waterproof and portable, the jammer case is our patent design, it can be installed in desert and more rain of bad weather. The Frequency band is optional, and the high power jammer is with excellent heat dispersion.

Main Function
• High-power portable multi-band jammer.
• Fully modular compact design with extremely high efficient cooling system provides system stability even in extreme climate conditions. The modular design also facilitates easy maintenance, repairs and upgrades.
• Jam up to six different jamming modules simultaneously, covering up to 20 different frequency bands.
• Increased total RF output power up to 350 Watts.
• Equipped with a wired remote control unit. The operator can ON/OFF each module through the wired remote control.
• Supplied by AC mains or DC power source.
• The jamming system has an active smart cooling system in a continuous working cycle.
• Based on our general design, we can further customize our systems for client-specific scenarios both for military and civil applications in order to provide the best individualized solution.
• Upgraded jamming signal source (DDS technology) to provide utmost efficiency.(option)
• Field programmability for rapid adjustment to frequency and output power. (option)
