Network jammer is a new type of information security product. It uses specific electromagnetic signals to form a shielding network in the area to be protected, making mobile phones unable to receive base station data. The following points should be noted about the installation of the shield:

1、 Before installing the equipment

① First, understand the orientation of the BTS, and try to make the shielding direction consistent with that of the BTS.

② Pay attention to whether there are metal objects around the machine to prevent signal reflection from affecting the shielding effect.

③ The best installation height should be 1.8-2.5m, which can be directly placed on the table or fixed on the wall or ceiling. The angle between the antenna and the ground is the best.

④ If indoor equipment such as signal enhancement amplifier is installed, it is not suitable to install network jammer.

⑤ The on-site signal strength is very important for the installation of the shield. Since there are many types of signals in the same environment, and the strength of each type of signal is different, understanding the field signal strength is helpful to the installation of the shield.

2、 Equipment installation

① According to the survey results, different signals shall be reasonably matched to achieve the best condition, and the interference degree outside the shielding area and the impact on the surrounding environment shall be fully considered.

② Considering the floor height of the shielding area, the signal in the high-rise area is better than that in the bottom area, so the network jammer can be better shielded by selecting the installation sequence from top to bottom.
