Optimizing the Installation of Signal Jammers in Examination Halls

Enhancing the Effectiveness of Signal Jammers through Proper Installation

Signal jammers are commonly used in examination halls to prevent unauthorized communication and maintain the integrity of the testing environment. However, some customers have reported subpar performance despite using high-quality jamming devices. Apart from considering the device’s specifications and performance, it is crucial to understand the correct installation methods and optimal placement of signal jammers to maximize their effectiveness.

Installation Considerations:

When setting up signal jammers in actual examination venues, it is essential to assess the overall effect of the chosen equipment. The installation process typically follows the original design plans. The most common installation positions for signal jammers include the sides of the front and back blackboards, the top of the blackboard in the middle, the top corners of the front and back walls of the examination hall, the middle area of the side walls, and the central beam of the hall.

Optimal Placement:

To ensure optimal performance, it is not recommended to place signal jammers on the podium or hide them inside the lectern for convenience. Placing the device in a confined space can hinder its heat dissipation, especially if the surroundings are made of metal. This can negatively impact signal transmission and directly affect the jamming effectiveness.


To achieve the desired results in examination halls, it is crucial to pay attention to the installation and placement of signal jammers. By following the original design plans and selecting appropriate installation positions, the effectiveness of these devices can be significantly enhanced. Avoiding improper placement, such as on the podium or within enclosed spaces, will ensure optimal heat dissipation and signal transmission, ultimately improving the overall performance of signal jammers in examination environments.
