Unparalleled Signal Blocking: Transforming Prison Safety with PrevailTec Digital Jamming Systems

The digital signal jammer is the jamming device with the latest digital signal scrambling technology to provide precise blocking performance and much lower radiation and power consumption.

The digital outdoor jammer effectively blocks mobile phone communications within the target area. It analyzes the downlink dedicated channel of the base station to obtain the baseband signal, then reorganizes it as an interference code to shield the downlink interference signal of the mobile phone. This product confidently supports the shielding of mobile phones of different standards without causing any interference to the uplink of the base station. Within the shielding area, it effectively blocks mobile phone communication services of various operators, including voice, data, SMS, and other services.

Digital Jammer Advantages:

1) Much lower output power, same blocking performance or even better: at least 15dB less than traditional analog high-power jammer.

2) Block TDD/FDD downlink of base station, no interference with uplink: for TDD cellular system, the regular high-power jammer cannot block the downlink of TDD base station (such as 5G NR and TD-LTE); while the digital jammer can easily block the TDD downlink signal without interference with uplink.

3) Less radiation to minimize the potential harm to the heath of the people inside the blocking area.

4) Less power consumption (50% less than that of the regular high-power jammer, therefore, less operation problems, less maintenance, but more stable operation and energy saving)
