    In order to protect the vital interests of the majority of candidates, the fair and impartial mobile phone signal jammer is an essential anti-cheating tool in the examination room of the college entrance examination. Like other important exams, the use of cell phone signal jammers is also highly valued in the examination room of the college entrance examination.

    The mobile phone signal jammer will have different effective shielding ranges in different places of use, because the shielding range of the mobile phone signal jammer is related to the signal strength of the field strength of the use environment, and is closely related to the signal field strength of the scene. Different types of mobile phones There may not be the same shielding range on the same site, so choose a shield according to the actual situation.

    Factors affecting the shielding range include, but are not limited to, distance, direction, barrier-free objects relative to the base station, wall materials of the site building, installation height of the shield, installation specifications, etc. Other factors should also be taken into consideration.

    Each antenna of the TX-B12H mobile phone signal shield produced by Shenzhen Texin Electronics Co., Ltd. transmits a signal of a frequency band. The standard antenna must correspond to the frequency band identifier on the host. Before the shield is turned on, it must be ensured that each antenna is connected Reliable, never use the device without an antenna.

    After the shield has been running for a long time, the surface temperature will rise to more than 50 degrees. This is a normal phenomenon, because the power amplifier of the shield is hot. The normal installation height of the mobile phone signal jammer is 1.8 meters to 2.5 meters, and it is installed in the target shielding area and the position where there are no obstacles between the target shielding area. If in a wall mount the antenna needs to be straight up. During use, in order to avoid possible interference with some electronic devices, the following commonly used devices should be used to maintain a certain distance.

    If the signal jammer cannot be used correctly, it will cause cheating in the examination room. Such consequences are very serious. I hope everyone can take it seriously. These misunderstandings must also be avoided.
