Test method for interference effect of mobile phone signal jammer.

  • 2022-07-05

Before installing the mobile phone signal jammer, it is still necessary to test the interference effect. After testing, it can be determined whether the mobile phone signal jammer meets the interference requirements of the whole use site, and the number of mobile phone signal jammers required at this site can be determined.

Before testing the Signal Jammer of mobile phones, you need to prepare common tools such as screwdrivers, patch panels, and many mobile phones from different operators. If there are professional technicians on site, professional detection equipment of spectrometer is also required.

During the test, find the nearest AC power socket, then connect the patch panel, transfer the patch panel to the position where the mobile phone signal jammer is placed, try to place it on the wall near the window at both ends of the use site, and place the mobile phone signal jammer between 1.8 meters and 2.5 meters away from the ground. If the site conditions are limited, it can also be placed directly on the desktop, and pay attention not to place the mobile phone signal jammer directly on the ground. At this time, you can energize the mobile phone signal jammer and turn on the switch.

According to the environment of the use site, choose the other end of the use site, or choose the position opposite to the cell phone signal jammer, place the cell phone on the desktop for 1-2 minutes, and turn on the spectrometer at the same time to detect whether each frequency band of the jammer signal is output normally. After the mobile phone stands for 1-2 minutes, you can check whether there is a signal displayed on the mobile phone. If there is no signal displayed, it indicates that the mobile phone has been interfered in this position. If there is a signal displayed, you can try to make a phone call or surf the Internet with data. If you can't use it normally, it means that the number of signal cells displayed on the mobile phone is false. In fact, the mobile phone can't complete the call and surf the Internet. If you can use the mobile phone to make a phone call or surf the Internet with data normally, it means that the mobile phone signal is not interfered at this position. You need to move a little distance towards the jammer and repeat the above operations, Until the cell phone signal is completely disturbed.
