What factors does the effective shielding distance of a cell phone signal jammer depend on?
The shielding range of the mobile phone signal jammer is mainly determined by the following factors.
1. The transmission power of the different frequency bands of the mobile phone signal jammer itself. In theory, the larger the transmission power, the larger the shielding range. And it is related to the frequency band of the signal frequency transmitted by this frequency band. If the transmit power is the same, the narrower the bandwidth, the greater the shielding range.
2. The shielding range of the mobile phone signal jammer also depends on the signal strength of the use site. The strength of the mobile phone signal at the site depends on whether there is a signal source for mobile phone signal transmission around the use site, that is, the operator's base station, commonly known as the antenna. tower. The distance from the signal tower to the scene determines the strength of the mobile phone signal at the scene. Of course, this signal source also includes an indoor signal distribution system, commonly known as a mobile phone signal amplification device. 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 scene cannot be changed, it is basically impossible to change the signal strength emitted by the signal source.
3. The shielding range of the mobile phone signal jammer is also related to the space layout and wall material of the use site. If the space environment of the use site is relatively transparent, the shielding range of the mobile phone signal jammer is much better than some environments with multiple compartments. And the shielding range of the mobile phone signal jammer is also related to the wall material on site. The shielding range of the mobile phone signal jammer and the material of the wall are basically glass walls, wooden walls, and gypsum board walls larger than brick walls and concrete walls. . If the wall is a sandwich panel wall with metal on both sides and foam in the middle, the interference signal of the mobile phone signal jammer is basically impenetrable.
