The Importance and Usage of Wireless Interference Devices in the Examination Hall

In this era of information, the participation of wireless interference devices in the examination hall is indispensable. With the help of these devices, it is impossible to cheat using mobile phones. So, how exactly are these wireless interference devices used? Let’s explore further.

Ensuring Examination Integrity with Wireless Interference Devices

Understanding the Installation and Usage of Wireless Interference Devices in Examination Halls

In preparation for the final exams, many schools have started early preparations to ensure the quality of the examination. As part of this process, the installation of wireless interference devices has become crucial. These devices play a vital role in preventing cheating through mobile phones during exams.

Installation Considerations:

During the installation of wireless interference devices, it is essential to consider the positioning of the main unit and antennas. Within a certain distance between the main unit and the antennas, there should be a strong signal magnetic field. Additionally, interference from the magnetic field surrounding the 220V power supply line should also be taken into account. Incorrect placement may interfere with the transmission of the signal and affect the overall shielding effect.

To achieve optimal signal performance, wireless interference devices can be securely fixed to the ceiling or walls using regular screws. After installation, it is crucial to check the connectivity of all components, including the power supply and other accessories. Any issues should be addressed promptly to ensure the proper functioning of the device.

Power Supply and Testing:

Once the installation is complete, the device’s power supply should be connected to a socket directly, utilizing a 220V power source. Afterward, the testing machine can be turned on. In case any issues arise during the startup process, users can contact the manufacturer for immediate assistance and problem resolution.

Importance of Purchasing from Reputable Manufacturers:

To ensure the quality and reliability of wireless interference devices, it is crucial to purchase them from reputable manufacturers. This guarantees that the devices meet the necessary standards and provide the desired level of performance.


In the digital age, wireless interference devices have become an essential tool in maintaining the integrity of examinations. By preventing cheating through mobile phones, these devices contribute to fair and unbiased evaluation. Proper installation, thorough testing, and purchasing from reputable manufacturers are key factors in ensuring the effectiveness and reliability of wireless interference devices.
