What are the benefits of cell phone jammers at the signaling layer?

Dojammer 2022-07-15

The signaling layer signal jammer samples the signal sent from the base station to the mobile segment through the signaling mobile phone and simulates the public network base station signal to transmit communication blocking signaling to the mobile phone by analyzing the frame code and recombining to induce the mobile communication equipment To achieve the purpose of shielding mobile communication signals.

Compared to traditional jammers, cell phone jammers have the following advantages at the signaling level:

1. The transmission power is small, and the green environmental protection does not affect physical health.

2. The shielding effect is good and the precision is high, which can realize the buttocks shielding without blind spots throughout the area.

3. The perimeter of the shield has high control accuracy.

4. It has good self-adaptability and can use the operator's network parameter changes to ensure the reliability of the system.

DHO0543 digital signaling level cell phone signal jammer is different from the traditional co-frequency rejection method. DHO0543 digital signaling level cell phone signal jammer uses digital technology, which greatly improves the signal shielding range while reducing power consumption and radiation.

DHO0543 digital (signalling level) cell phone signal jammer supports a full range of frequency bands, which can shield the 2G, 3G, 4G and 5G frequency bands of China Mobile, China Unicom and China Telecom.

Features

Independent frequency band shielding is controllable;

At the same time, it realizes the shielding function;

Depending on the field strength, the shielding range is 1 to 30 meters;

The shielding output power is adjustable to improve the accuracy of the shielding;

Adoption of TCP/IP transmission mode, unified platform management;

With anti-theft, power failure, malfunction and other alarm functions;

It does not affect other electronic instruments and avoids false alarms;

Low power consumption and low radiation, harmless to human body, green and environmental protection;

TDD works synchronously to ensure it does not interfere with the base station;

Effective shielding area of ​​a single system: ≥1500㎡;

Synchronization sensitivity of the TDD system RSRP ≤ -105 dBm;

TDD system synchronization accuracy error ≤ 10us;

Each frequency band supports an independent switch, and the device supports the function of automatic debugging after power-on. After adjusting the output power, the device will keep the adjusted output power when the input level is above the minimum input level.
