How to test the effect of the full-band signal jammer?
Before installing a full-band signal jammer, it is essential to test the shielding effect. The test can determine whether the signal jammer meets the shielding requirements of the entire conference room, and can determine how many jammers are needed for this conference room. This article will introduce you how to test the full-band cell phone jammer.
Before testing the full-band signal jammer, you need to prepare the tools and equipment required for the test. Prepare common tools such as screwdrivers, power strips, and step ladders, and prepare mobile phones of three different operators. If there are professional technicians on site, it is recommended to equip professional testing equipment of spectrum analyzer.
When testing, first find a nearest AC 220V power supply socket, and connect the power strip to the socket. Then, transfer the patch panel to the position where the signal jammer is placed. It is recommended to place it on the wall near the window at both ends of the conference room, and try to place the signal jammer as high as possible. If the site conditions are limited, it can also be placed directly on the conference table, but be careful not to place it directly on the ground. At the same time, power up the signal jammer and turn on the switch.
According to the environment of the meeting room, choose the other end of the meeting room, or choose a position opposite to the full-band signal jammer, and place mobile phones of three different operators on the table for 1-2 minutes. At the same time, turn on the spectrum analyzer on the desktop where the mobile phone is placed, and check whether each frequency band of the jammer signal is output normally.
After the mobile phone is left standing for 1-2 minutes, you can check whether there is a signal displayed on the mobile phone. If it shows that there is no signal, it means that the mobile phone has been blocked at this location. If it shows that there is a signal, you can try to make a call or connect to the Internet with data. If it cannot be used normally, it means that the number of signal bars displayed on the mobile phone is false. In fact, the mobile phone cannot complete calls and surf the Internet. If the mobile phone can be used to make calls or data to surf the Internet normally, it means that the mobile phone is not blocked at this position. You need to move a little distance to the jammer, and then repeat the above operations until the mobile phone is blocked.
In short, before installing a full-band signal jammer, it is very necessary to test the shielding effect. Through the test, it can be determined whether the signal jammer meets the shielding requirements of the entire conference room, and it can be determined that the conference room needs several jammers. We recommend that you use the above test methods to ensure the efficiency and accuracy of the full-band signal jammer.
