After installing the mobile phone signal jammer, will it affect the mobile signal of other floors?

When installing a mobile phone signal jammer, we all have such questions. After installing a mobile phone signal jammer, how should we deal with mobile phone signals that affect other floors?


To solve this problem, we first need to understand the working principle of the mobile phone signal jammer. The signal of the mobile phone is connected with the base station through radio waves within a certain range, and the mobile phone receives the signal of the base station. The mobile phone signal jammer forms garbled code interference in the process of work, which makes the mobile phone unable to receive the service signal of the base station, causing the mobile phone unable to connect to the base station.

In fact, the shielding effect of the mobile phone signal jammer is mainly affected by the transmission power of each frequency band of the jammer, the distance between the jammer and the base station, and whether there are obstacles between the base station and the site. For example, if the installation height of the jammer is too low, it is equivalent to artificially creating some obstacles, causing the jamming signal to be weakened and attenuated, thus affecting the jamming effect. And most mobile phone signal jammers are not recommended to be used through the wall. After the interference signal penetrates the wall, it will attenuate seriously, and the interference effect will be greatly reduced. The concrete structure between the upper and lower floors will have a strong weakening effect on the interference signal, so the influence of the jammer on other floors will be very small. If the mobile phone signal of other floors is affected, the influence on the upper and lower floors can be reduced by adjusting the transmission power of the jammer or installing a directional antenna.
