Before the conference room cell phone signal jammer is officially launched, the shielding effect of the conference room cell phone signal jammer should be tested first, so that the installation location and quantity of the conference room cell phone jammer can be selected.
First, preset the installation position of the mobile phone signal shielding device in the conference room, and place the mobile phone signal jamming device in the conference room on the desktop, usually at the front and back of the conference room, even in a corner. Turn on the power and turn on the switch to shield effect test.
During the test, hold the mobile phones of the three operators and place them in the opposite corners of the conference room, which is also the farthest position from the mobile phone signal shielding device in the conference room, and then leave the mobile phones for about 2 minutes. Operation, and then check whether the mobile phone signal is blocked on the mobile phone screen. If it shows no mobile phone signal, then the mobile phone of the operator is blocked. If the mobile phone shows that there is a signal, you can try to call the operator's customer service hotline, or use the mobile phone Network for data access. If it is possible to make calls or access the Internet via data, move the cell phone to a position close to the cell phone signal jammer in the conference room, and reciprocate until the cell phone is completely blocked, and the cell phone cannot make calls or access data. In this way, the shielding range of the mobile phone signal jammer in the conference room is determined, and this shielding range is used to determine the number of mobile phone signal jammers in the conference room.
If the mobile phone signal in 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 cell phone signal jammer cannot shield, and then according to the tested frequency band , to do the positive interference of the high-power shielding module for this frequency band. First, download the Cellular-Z mobile phone APP with an Android phone, and then open the mobile phone APP under the premise of turning on the mobile phone signal jammer in the conference room, and then take a screenshot and send it to the manufacturer of the conference room mobile phone signal jammer, which will be determined by the manufacturer.
