How effective is the cell phone signal jammer through walls?
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 jammer 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, 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.
