How to install the telephone jammer? The effect is good

How to install the telephone jammer? The effect is good

  • 2023-01-07
Some customers found that in the actual use process, the shielding effect of the telephone jammer in the examination room is not ideal after it is turned on. If the factors of poor shielding equipment selection and performance are excluded, the installation position of the shielding equipment will become the main factor affecting the shielding effect.

The telephone jammer is generally installed according to the customized scheme. The most common installation positions of the shielding equipment are: the two sides of the front and rear blackboard or the top of the middle position of the blackboard, the middle area of the walls on both sides of the classroom, and so on. However, some directly place shielding equipment on the platform or hide it in the desk. This method should never be advocated, because it is hidden in the lectern and will not promote the heat dissipation of the telephone jammer in the examination room. If the lectern is made of metal, it will be more harmful to signal transmission and thus directly affect the shielding effect.

Theoretical analysis shows that: in all possible locations, when the telephone jammer in the examination room is an omnidirectional antenna, the middle of the classroom is the most ideal location for shielding effect, that is, if there is a beam in the middle of the classroom, it is best to hang the shielding equipment below it, but this will bring two problems: first, it will affect the aesthetics; second, the classroom must have enough height space. Therefore, due to these two points, the most ideal location is the first installation location rejected.

From the analysis of signal transmission path: the mobile phone signals in the examination room are all 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 examination room telephone jammer in the middle of the wall facing the base station, so as to maximize the shielding effect of the shielding equipment.
