How to test the cell phone signal jammer in the conference room from dojammer's blog

Before the cell phone signal jammer in the conference room is officially activated, the shielding effect of the cell phone signal jammer in the conference room must be tested first, so that the installation location and number of cell phone signal jammers in the conference room can be selected.

First, preset the installation location of the cell phone signal jammer in the conference room, and place the cell phone signal jammer in the conference room on the desktop. Generally, it is placed in the front and back corners of the conference room. After the power is turned on and the switch is turned on, the shielding effect can be tested.

During the test, hold the mobile phones of three operators and place them in the opposite corner of the conference room, which is also the farthest position from the cell phone signal jammer in the conference room. Then let the mobile phone stand for about 2 minutes. Do not operate the mobile phone during this period, and then check whether the mobile phone signal on the mobile phone screen is blocked. If it shows no cell phone signal, then the mobile phone of this operator is blocked. If the mobile phone shows a signal, you can try to call the operator's customer service hotline, or use the mobile network for data Internet access. If you can make a call or access the Internet, then move the mobile phone to a position close to the cell phone signal jammer in the conference room, and go back and forth until the mobile phone is completely blocked, and the mobile phone cannot make calls or access the Internet. This is used to determine the shielding range of the conference room cell phone signal jammer, and the number of conference room cell phone signal jammers to be used is determined by this shielding range.

If the cell phone signal at the conference room is strong, and the low-power conference room cell phone signal jammer cannot completely shield the entire conference room, you can determine the signal frequency band that the conference room mobile phone signal jammer cannot shield, and then use the high-power shielding module to interfere with this frequency band based on the tested frequency band. First, you need to download the Cellular-Z mobile phone APP on an Android phone, and then open this mobile phone APP while turning on the conference room cell phone signal jammer, and then take a screenshot and send it to the manufacturer of the conference room cell phone signal jammer, so that the manufacturer can determine the cell phone signal frequency band that the conference room cell phone signal jammer cannot shield. Finally, by using a high-power shielding module to cover the frequency band with a strong signal, the cell phone signal in the conference room can be shielded.
