Enhancing Information Security in Exam Halls and Preventing Cheating

Signal Jammers have become a common tool in exam halls due to their ability to provide information security. However, it is crucial to use these devices correctly to ensure optimal interference and prevent any potential accidents. This article will discuss the importance of proper installation and usage of Signal Jammers, focusing on their role in maintaining exam integrity and preventing cheating.

The Need for Signal Jammers in Exam Halls

In today’s digital age, students often resort to using their smartphones during exams, compromising the integrity of the examination process. To address this issue, Signal Jammers have emerged as a solution to protect the information security of exam halls.

The Consequences of Improper Usage

Improper usage of Signal Jammers can lead to ineffective interference and even accidents in exam halls. It is essential to follow specific guidelines to ensure the optimal functioning of these devices.

Correct Installation Procedures

  1. External Antenna Connection: When using a Signal Jammer with an external antenna, it is crucial to correctly insert and install the antenna according to the provided instructions. Failure to do so may result in damage to the device if the power switch is turned on without the antenna installed.
  2. Ideal Installation Height: The Signal Jammer should be installed at a height of 1.8 to 2.5 meters, preferably in a location without any obstacles between the device and the target area.
  3. Wall Mounting: For wall-mounted installations, the antenna should be positioned vertically upwards. If the Signal Jammer has a built-in antenna, it can be installed in the middle of the wall. In larger rooms, multiple devices can be stacked to achieve better coverage.

Proper Power Connection

When connecting the power supply, it is essential to check the power switch of the Signal Jammer and ensure it is in the off position. Insert the power interface into the bottom side of the device, and connect the other end of the power plug to a 220V power source.

Enhancing Exam Integrity with Signal Jammers

To prevent students from using their smartphones to transmit information, leak exam questions, or engage in cheating behaviors, the BaiKang brand Signal Jammer effectively interferes with all types of mobile signals (2G, 3G, 4G, 5G) across the entire frequency range. This ensures a fair examination environment and upholds the integrity of the testing process.


Signal Jammers play a crucial role in maintaining information security and preventing cheating in exam halls. However, it is vital to follow proper installation and usage procedures to ensure optimal interference and avoid any potential accidents. By implementing these measures, educational institutions can create a fair and secure environment for examinations, promoting academic integrity among students.
