What factors determine the effective shielding distance of mobile phone signal jammer?

  • 2022-04-12

The shielding range of mobile phone signal jammer is mainly determined by the following factors.

1. The transmission power of different frequency bands of mobile phone signal jammer itself. Theoretically, the larger the transmission power, the larger the shielding range. And it is related to the frequency band of the signal frequency transmitted by the frequency band. If the transmission power is the same, the narrower the bandwidth is, the larger the shielding range is.

2. The signal strength of the mobile phone on the site depends on whether there is a signal source for mobile phone signal transmission around the site, that is, the operator's base station. The distance from the base station to the site determines the strength of the mobile phone signal on the site. Of course, the signal source also includes the indoor signal distribution system. The distance from the signal source to the scene is the most critical factor that determines the shielding range of the mobile phone signal jammer. Because the distance from the signal source to the site cannot be changed, and at the same time, it is basically impossible to change the signal strength transmitted by the signal source.

3. The shielding range of mobile phone signal jammer is also related to the spatial layout and wall material of the use site. If the space environment on the site is relatively transparent, the shielding range of mobile phone signal jammer is much better than that with multiple compartments. Moreover, the shielding range of mobile phone signal jammer is also related to the wall material on site. The shielding range and wall material of mobile phone signal jammer are basically that glass wall, wood wall and gypsum board wall are larger than brick wall and concrete wall. If the wall is a sandwich panel wall with metal foam inside, the interference signal of the mobile phone signal jammer is basically impossible to penetrate.
