Question: What is the effect of the cell phone jammer through the wall?
Answer: The wall penetration performance of the shield depends on the following aspects:
1. The material of the wall;
The wall is divided into brick-concrete, steel-concrete, and other materials, such as glass, wood, gypsum board, etc. The penetration order of the mobile phone signal jammer to the wall is: glass>gypsum board>wooden>brick-concrete>steel-concrete wall .
2. The thickness of the wall;
The thinner the wall, the greater the penetration.
3. The frequency of the signal;
The mobile phone signal jammer is composed of RF modules with different frequencies. The lower the signal frequency, the better the penetration of the wall, 800>900>1800>2100>2300>2600, etc.
4. The power of the RF module;
The greater the power of the mobile phone signal jammer module, the stronger the penetration.
