Police EOD is mainly aimed at the frequency band of remote control, while remote control explosives are explosives designed by criminals to create terrorist incidents. These remote control explosives are detonated by the remote control or mobile phone, so to cut off the remote control signal between the remote control and the explosive, it is necessary to interfere with the signal frequency that can be used as a remote control.

There are more frequency bands that can be used for remote control. The common ones are 135M, 433M, 2.4G and 5.8G of WiFi, and of course there are frequencies that use mobile phone signals. There are some criminals who use non-conventional frequencies, so it is impossible to determine the frequency used for remote control of explosives. The best way is to use a full-band police EOD device. No matter what frequency the terrorist uses, as long as the full-band police After the interference is turned on with the detonation device, terrorists cannot use remote control to detonate explosives. This gives our special police sufficient time to detonate and protect the lives and property of the people.

Question: What is the wall penetration effect of the cell phone signal jammer?

Answer: The wall penetration performance of the jammer depends on the following aspects:

1. The material of the wall;

The walls are divided into brick-concrete, steel-concrete, and other materials, such as glass, wood, gypsum board, etc. The order of penetration of the cell phone signal shield on the wall: glass>gypsum board>wood> brick-concrete>steel-concrete wall .

2. The thickness of the wall;

The thinner the wall thickness, the stronger the penetration.

3. The frequency of the signal;

The mobile phone signal jammer is a combination of RF modules of different frequencies. The lower the signal frequency, the better the penetration into the wall, such as 800>900>1800>2100>2300>2600.

4. The power of the RF module;

The greater the power of the mobile phone signal jammer module, the stronger the penetration.
