The main task of using cell phone jammers in schools is to prevent candidates from cheating by using cell phones and other communication devices in the examination room and ensure the fairness and impartiality of the examination. But what should we pay attention to when installing and using cell phone jammer?

1、 Installation location

The components of mobile phone jammer generally include: host, antenna and power cord. When installing the cell phone jammer, it is disturbed by the magnetic field due to a certain distance around the host, antenna and power line. If the position is incorrect, it is likely to interfere with the transmission of interference signals and affect the interference effect.

2、 Installation details

1. The installation height of cell phone jammer shall be at least 1.8m above the ground.

2. The installation shall be far away from the signal tower. The closer to the signal tower, the smaller the interference radius.
