The Digital Signal Jammer can help to block the mobile signals for any area that are confronted with cellular communication problems: for example, loud incoming call rings, loud telephone conversations, secret leaking and bomb explosion through Mobiles, electromagnetic radiation to gas station, chemical material warehouse and hospital equipments. The product can block 2G/3G/4G/5G/WiFi signals, and does not interfere with any MNO's base station of any standard. It has significantly better jamming performance comparing to traditional analog and digital signal jammers. 

The Digital Signal Jammer is signaling-level mobile communication blocking system, it adopts baseband technology to scan the surrounding RF signals and outputs the modulated interference signals to cut-off communication between mobile phones and cellular base-stations, effectively disabling mobile phones within the shielding range of the jammer, preventing them from receiving signals and from transmitting signals.

Upon activating Mobile Signal Jammer, all idle phones will indicate “NO SERVICE”. Incoming calls are blocked as if the cellular phone is OFF. When Mobile Signal Jammer is turned off, all cellular phones will automatically re-establish communications and provide full service.

• Third-generation FPGA-powered DDS technology for stronger and more precise jamming performance in urban area with strong cellular signal

• System targets downlink transmission only; local MNO base station operation not impeded

• Passive frequency spectrum scanning to pinpoint sub-band to be suppressed 

• Comprehensive safe electronic design: slow start-up circuit, stable integrated layout, protection against overheating, output under/overpower, and standing wave.

• Integrated design in one weatherproof package for easy installation and replacement
