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

Before testing the mobile phone signal jammer, it is necessary to prepare common tools such as screwdrivers, patch panels, herringbone ladders, and mobile phones of different operators. If there are professional technicians on site, it is also necessary to equip professional testing equipment of spectrometer.

During the test, find the nearest 220V AC power supply socket, connect the patch panel, transfer the patch panel to the place where the mobile phone signal jammer is placed, try to place it near the wall at both ends of the site near the window, and try to place the mobile phone signal jammer higher. If the site conditions are limited, it can also be placed directly on the desktop, and be careful not to place it directly on the ground. At this time, power on the mobile phone signal jammer and turn on the switch.

According to the environment of the site, choose the other end of the site, or choose the position opposite to the mobile phone signal jammer, and leave the mobile phone on the desktop for 1-2 minutes. On the desktop where the mobile phone is placed, the spectrometer is also turned on to check whether the signals of each frequency band of the jammer are output normally. After the phone has been left standing for 1-2 minutes, you can check whether there is a signal displayed on the phone. If there is no signal displayed, it indicates that the phone has been interfered at this location. If there is a signal displayed, you can try to make a call or use data to access the Internet. If it cannot be used normally, it means that the number of signal cells displayed on the mobile phone is false. In fact, the mobile phone cannot complete the call and access the Internet. If you can use the mobile phone to make a call or use data to access the Internet normally, it means that the mobile phone is not disturbed at this location, It is necessary to move a little distance towards the mobile phone signal jammer and repeat the above operation until the mobile phone is interfered.
