With the rapid development of modern communication technology, science and technology security enterprises must keep pace with the times and constantly develop their own strength to meet various challenges. The high popularity of mobile phones has not only brought convenience to people, but also brought new problems to communication security and confidentiality. Eavesdropping, leakage of secrets, cheating in examination rooms, gas station explosions and other incidents have occurred one after another, which has accelerated the promotion and use of electronic jammers. It is mainly used in examination rooms, prisons, gas stations, detention centers, interrogation rooms, etc. With the increasing use of electronic jammers in social life, some people have greatly reduced their shielding performance due to non-standard installation and use. Therefore, the following key points for installation and use need to be well known.

1、 Before installing the electronic jammer, you should first understand the location of the base station and try to make its direction follow the direction of the base station.

2、 When installing the equipment, pay attention to whether there are metal objects around the machine to avoid signal reflection and affect the shielding effect.

3、 The installation height should preferably be between 1.8-2.5m. The electronic jammer can be directly placed on the table or installed on the wall

4、 The omni-directional antenna shall be perpendicular to the ground, and the directional antenna shall be tilted forward.

5、 If a signal enhancement amplifier is installed indoors, it is necessary to increase the number of electronic jammers installed.

6、 Understand the on-site signal strength, and make reasonable collocation for different signals
