Customers often ask in what kind of environment can the effect of the cell phone signal jammer be maximized? Why do mobile phone signal jammers not work well in some places, or the shielding effect is relatively poor? In fact, this is closely related to the electromagnetic environment around the place where the jammer is used. So in what environment will the shielding effect be relatively poor?

1. The environment where the mobile phone signal jammer is used is not transparent, there are many compartments, or walls are blocked. This is because the penetration of wireless signals is relatively poor, which depends on the frequency of the transmitted signal. The higher the frequency, the worse the penetration, or diffraction performance.

2. The place where the jammer is used is close to the base station. The mobile phone signal will be relatively strong in places close to the base station. If the jammer wants to shield the mobile phone signal, the signal strength of the emitted signal must be stronger than the mobile phone signal on site, so that the mobile phone signal can be shielded.

3. There is an indoor signal distribution system in the building where the mobile phone signal jammer is used, commonly known as a mobile phone signal amplifier. The place with a mobile phone signal amplifier is similar to the place close to the base station. If you want to shield the mobile phone signal, the jammer needs to have a larger transmission power.

When using a cell phone signal jammer, you need to pay attention to the distribution of base stations around the site of use and confirm whether there is an indoor signal distribution system in the building. If there are too many compartments, multiple jammers are needed to cooperate with the shielding. If the base station is close, you can coordinate with the operator to adjust the direction of the base station antenna plate, so that the mobile phone signal strength at the site can be reduced, thereby improving the shielding effect of the jammer. In an environment with an indoor signal distribution system, when using the jammer, let the user turn off the power of the indoor signal distribution system to reduce the signal strength, which can improve the effect of the jammer to a certain extent.
