In the examination, in order to ensure the level of the examination room and prevent electronic cheating, the state stipulates that mobile jammers must be used during the college entrance examination, postgraduate examination, and English four and six levels, so as to create a level playing field for candidates. The mobile cell phone jammer is a high-tech product that our factory adopts foreign advanced technology, aims at the continuous development of the communication system, and carefully develops the high-tech product according to the actual situation of foreign mobile communication. It can be 1 to 20 meters in a straight line, about 10-200 square meters, and the shielding range can be adjusted according to the different sites required.

Is cell phone signal shielding harmful to human body and cell phone?
The strength of the electromagnetic signal emitted by the mobile phone jammer is very weak, and the test data shows that this signal strength is far from harmful to the human body. At the same time, the mobile phone signal jammer only blocks the forward signal of the mobile phone, so that the mobile phone cannot establish contact with the base station. Therefore, it will not cause any damage to the mobile phone itself.
Is there any difference in the operating distance of the mobile phone jammer when used indoors and outdoors?
The effective shielding distance of the mobile phone signal jammer refers to the indoor distance. In outdoor open areas, the effective distance of shielding can range from tens of meters to hundreds of meters. It should be pointed out that whether it is used outdoors or indoors, the effective range of mobile phone jammers has a certain relationship with the environmental conditions at the time. Such as the distance from the base station, the placement location, etc. Therefore, when using mobile phone signal shielding, this factor should be fully considered to avoid shielding blind spots and affecting the shielding effect.
