Where is the mobile phone signal jammer installed in the examination room with the best interference effect?

  • 2022-04-13

During the construction of most standardized examination rooms, the installation of mobile phone signal jammer in the examination room is included. However, in the actual use process, some customers will always find that the interference effect is not ideal after the mobile phone signal jammer in the examination room is turned on. If excluding the factors of poor selection and performance of the interference equipment itself, how to install the interference equipment, And how to choose the installation position of jamming equipment will become the main factor affecting the jamming effect.

The mobile phone signal jammer in the examination room will generally be installed according to the original design drawings. The most common installation positions of the jamming equipment are: the two sides of the front and rear blackboards or the top of the middle of the blackboard, the top corners of the front and rear walls of the examination room, the middle area of the walls on both sides of the classroom, the middle beam of the classroom, etc. However, some jamming equipment are directly placed on the podium or hidden in the desk for convenience and convenience. This method cannot be advocated, because it is hidden in the desk, which is not only detrimental to the heat dissipation of the mobile phone signal jammer in the examination room, but also detrimental to the signal transmission if the desk is made of metal, thus directly affecting the interference effect.

If the beam is installed in the middle of the classroom, the interference effect may be the best. If the beam is installed in the middle of the classroom, the interference effect may be the best. In theory, if the beam is installed in the middle of the classroom, the interference effect will be caused by the two devices. Therefore, because of these two points, this most ideal position is the first installation position to be rejected.

Analysis from the signal transmission path: the mobile phone signals in the examination room and classroom are remote base station signals, which are transmitted to the classroom through doors and windows. Then, the most reasonable installation position is to select the installation position of the mobile phone signal jammer in the middle of the wall facing the base station, so as to give full play to the interference effect of the interference equipment to the greatest extent.
