Maximizing the Effectiveness of Signal Jammers in Examination Halls: The Importance of Installation and Placement


In the construction process of most standardized examination halls, the installation of signal jamming devices is a common practice. However, some customers may find that the effectiveness of these devices is not ideal during actual usage. Apart from factors such as poor selection and performance of the jamming equipment itself, the installation process and placement of the devices also play a crucial role in determining their effectiveness. This article aims to explore the significance of proper installation and placement of signal jammers in examination halls to maximize their efficiency.

The Impact of Installation and Placement on Signal Jamming Effectiveness

Installation Process:

Signal jammers in examination halls are typically installed according to the original design plans. The most common installation locations for these devices include the sides of the front and back blackboards, the top of the blackboard in the middle, the corners of the walls at the front and back of the classroom, the middle area of the side walls, and the middle beam of the classroom. However, it is not recommended to place the jamming devices on the podium or hide them inside the lectern for the sake of convenience.

Placement Considerations:

Proper placement of signal jammers is crucial to ensure their optimal performance. Placing the devices in a closed environment, such as inside a lectern, can hinder their heat dissipation, thereby affecting their jamming effectiveness. Moreover, if the surrounding environment is made of metal, it further impedes the transmission of signals, directly impacting the jamming efficiency. Therefore, it is essential to consider the placement of signal jammers in areas that allow for proper ventilation and minimal interference.


In conclusion, the installation and placement of signal jammers in examination halls significantly impact their effectiveness. Following the original design plans and avoiding convenient yet ineffective placements, such as on the podium or inside the lectern, is crucial. Additionally, selecting appropriate locations that facilitate proper heat dissipation and minimize signal interference is essential for maximizing the efficiency of these devices. By prioritizing proper installation and placement, examination halls can ensure a secure and controlled testing environment, free from unauthorized communication.
