Judging from the size of the cell phone signal jammer in the examination room, it is not very large and can be conveniently placed in any position in the examination room. There is no need to open up a place and there is no noise. Bring a big impact.

1. Small size and no noise

Judging from the size of the cell phone signal jammer in the examination room, it is not very large and can be conveniently placed in any position in the examination room. There is no need to open up a place and there is no noise. Bring a big impact.

2. It is harmless to the human body and has no effect on other electronic equipment

Don't worry about its impact on other electronic equipment, the signal jammer mainly shields the mobile phone signal. At the same time, it is used to cut off the connection between the mobile phone and the base station. The Borch Space-Time mobile phone signal jammer has passed the radiation test certification of the Guangdong Occupational Health Inspection Center and the radiation value meets the standard and will not cause harm to the human body.

3. Wide coverage and low cost

With the development of science and technology, the coverage of 5G signal jammers in the test room of Electronics has become more and more extensive, and one set can cover a large area, greatly reducing the cost.

The mobile phone signal jammer came into being. The essence of the mobile phone signal jammer is: electromagnetic interference is applied to the wireless network on which the mobile phone communication depends, so that the mobile phone cannot be connected to the network, and thus cannot receive information from the mobile network, and cannot send information through the network. But it has no effect on the signal generated by the mobile phone.

In order for the mobile phone signal jammer to effectively interfere with the mobile network, it must be ensured that the signal field strength of the jammer should be much greater than the field strength of the mobile signal BCH in the interference area. Therefore, the same jammer uses different locations and the effective area size of the interference However, the local BCH field strength is generally stronger as it is closer to the base station, and the area where the jammer reaches effective interference is smaller. Generally, the interference radius can only reach 0.5-9m; if the farther away from the base station, the BCH field strength is relatively weak. Then the radius of the jammer to achieve effective interference is larger, up to ten to tens of meters. Therefore, before using the interference device, the local BCH field strength should be fully considered, and then the location, number and combination of the interference device should be determined according to the size of the interference area.
