Some customers have found that in the actual use process, the shielding effect of the wireless frequency jammer in the examination room is not ideal after it is turned on. If the factors of the selection and poor performance of the shielding equipment are excluded, the installation position of the shielding equipment will become the main factor that affects the shielding effect.
Wireless frequency jammers are generally installed according to customized solutions. The most common installation positions for wifi signal jammer are: the sides of the front and rear blackboards or the top of the middle of the blackboard, the middle area of the walls on both sides of the classroom, etc., but some directly place the wifi disruptor . On the lectern or concealed within the lectern. This method should never be advocated, because it is hidden in the desk and will not promote the heat dissipation of the wireless frequency jammer in the examination room. If the desk is made of metal material, it will be more unfavorable for signal transmission and thus directly affect the shielding.
Theoretical analysis shows that: in all possible installation positions, when the wireless frequency jammer in the examination room is an omnidirectional antenna, it is the most ideal position for the shielding effect to be installed in the middle of the classroom, that is to say, if there is a beam in the middle of the classroom, the It is best to have shielded equipment hanging below it, but this poses two problems: first, it will affect the aesthetics, and second, the classroom must have sufficient height space. So, because of these two points, this most ideal position is the first installation position that is rejected.
Analysis from the signal transmission path: The mobile phone signals in the classroom of 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 choose the installation position of the wireless wifi bluetooth jammer in the examination room in the middle of the wall on the side facing the base station, so that the shielding effect of the shielding device can be maximized.
