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 equipment. This product is suitable in executive offices, board meetings, conferences, seminars, libraries, cinemas, religious places, public transport, concert halls, restaurants and educational institutions, Prisons, etc.

The Digital Signal Jammer transmits strong power radio signals to cut-off communications between Mobile 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.

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

2. System targets downlink transmission only; local IPS base station operation not impeded.

3. Passive frequency spectrum scanning to pinpoint sub-band to be suppressed .

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

5. Integrated design in one weatherproof package for easy installment and replacement.
