Where should the mobile phone signal blocker be installed in the examination room for the best shielding effect?
In the construction process of most standardized test rooms, the project of installing mobile phone signal blockers in the test room is included. However, some customers will always find that after the mobile phone signal blockers in the test room are turned on, the shielding effect is not ideal in the actual use process. If you exclude the factors of poor shielding equipment selection and working performance, how to install the shielding equipment and how to choose the installation location of the shielding equipment will become the main factors affecting the shielding effect.
The mobile phone signal shielding device in the examination room is generally installed according to the original design drawings. The most common installation locations for shielding equipment are: on both sides of the front and rear blackboards or the top of the middle of the blackboard, in the top corners of the front and rear walls of the examination room, on both sides of the classroom The middle area of the wall, the beam in the middle of the classroom, etc., but there are still some shielding devices that are directly placed on the lectern or hidden in the lectern for the sake of convenience. This method is absolutely not recommended, because hidden in the desk, not only is not conducive to the heat dissipation of the mobile phone signal blocker in the examination room, if the desk is made of metal, it is even more unfavorable for signal transmission, which directly affects the shielding effect.
Of all the possible installation positions, evaluate from a theoretical analysis: if the mobile phone signal jammer in the examination room is an omnidirectional antenna, then it is the most ideal position for coverage and shielding effect to be installed in the middle of the classroom, that is, if the middle of the classroom If there is a beam, it is best to hang the shielding equipment below it, but this will bring two problems: one is that it affects the appearance, and the other is that the classroom must have enough headroom. Therefore, because of these two points, this most ideal location is the first to be rejected.
Analysis from the signal transmission path: The mobile phone signals in the classroom of the examination room are all remote base station signals, and are transmitted to the classroom through doors and windows. Then, the most reasonable installation location is to select the installation location of the cell phone signal jammer in the examination room. The middle of the wall on the side of the base station, so that the shielding effect of the shielding device can be maximized.
