How far can a telephone jammer shield?

How far can a telephone jammer shield?

  • 2022-11-27

The shielding distance of the telephone jammer depends not only on the efficiency of the equipment itself, but also on the actual site terrain, nearby base stations, building materials, and whether there are unnecessary obstructions. For example, when the signal passes through reinforced concrete, glass and wood, the degree of signal attenuation is different, which will more or less have some impact.

In today's communication era, there are more and more places where telephone jammers are used, such as examination halls, gas stations, meeting rooms and other places. Shielding equipment is used in these places to shield the mobile phone signal, so that the mobile phone does not need to be turned off, and also avoids some unnecessary trouble.

The working mode of the telephone jammer is that the frequency band of the transmitted jamming signal is used to shield the signal band of the mobile phone receiving base station. In general, the power of the transmitting frequency band of the shielding device is greater than the power of the received signal of the mobile phone, so that the mobile phone signal can be shielded. On the contrary, it will not work and will not affect the use of mobile phones. Therefore, more attention should be paid to these problems when using these shielding devices. Of course, the effective coverage area of the telephone jammer is not supported by more accurate data, and there are many factors that can affect it. Before choosing it, we should test the interference effect of the device more through the mobile phone, assess the field environment, and then decide whether it is necessary.
