Signal jamming devices, such as full-band signal jammers, are commonly used in various settings to block unwanted signals. However, some customers have found that the effectiveness of these devices is not ideal during actual usage. Apart from factors such as device selection and performance, the installation location of the jamming device plays a significant role in determining its effectiveness. This article aims to explore the impact of installation location on the shielding effect of signal jamming devices.
The Common Installation Locations:
The most common installation locations for signal jamming devices include the sides of the front and back blackboards or the top of the blackboard in the middle position, as well as the middle area between the walls on both sides of the classroom. However, there are also cases where the jamming device is placed directly on the podium or concealed within the lectern. This practice should not be encouraged as it hampers the heat dissipation of the signal jamming device when hidden inside the lectern. Moreover, if the lectern is made of metal, it further hinders signal transmission, directly affecting the shielding effect.

The Ideal Installation Location:
Theoretical analysis suggests that among all possible installation locations, the most ideal position for a full-band signal jamming device in a classroom is the middle position. If there is a beam in the middle of the classroom, suspending the jamming device below it would yield the best results. However, this presents two problems: firstly, it affects aesthetics, and secondly, the classroom must have sufficient height space. Due to these two factors, this ideal location is often rejected as the first choice for installation.
Signal Transmission Path Analysis:
The mobile signals within the examination classroom are transmitted from distant base stations through doors and windows. These signals are then received by mobile phones within the classroom. The signal jamming device works by blocking these signals, preventing them from reaching the mobile phones. Therefore, the installation location of the jamming device should be strategically chosen to intercept the signals effectively.
Conclusion:
In conclusion, the installation location of a signal jamming device significantly impacts its effectiveness. While the ideal location may be rejected due to aesthetic and spatial constraints, it is crucial to consider alternative positions that allow for optimal signal interception. By selecting the appropriate installation location, the full potential of signal jamming devices can be realized, ensuring a secure and controlled environment in various settings.
