Ensuring a Fair and Secure Testing Environment with Effective Signal Blocking
With the increasing prevalence of 5G smartphones, the potential for exam candidates to exploit these devices for cheating purposes has become a concern. To address this issue, schools have installed Signal Jammers to prevent candidates from using various high-tech communication methods to cheat. This article explores the key considerations in deploying these jammers, including the frequency bands to be blocked, the effective blocking distance, and the stability of the jamming effect. Additionally, it highlights the non-disruptive nature of these devices and their compliance with national safety standards, ensuring the well-being of invigilators and candidates.

Frequency Band Blocking:
Signal Jammers installed in schools primarily aim to block the signals of 2G, 3G, 4G, and 5G mobile phones, as well as other signals such as WiFi, Bluetooth headphones, and walkie-talkies. By effectively blocking these signals, schools can significantly reduce the risk of candidates using unauthorized communication devices during exams. This comprehensive approach ensures a fair and unbiased testing environment.
Effective Blocking Distance:
In order to cover an entire examination room, at least one Signal Jammer should be installed. The jammer must be capable of blocking wireless signals within the entire room without interfering with the normal lives of nearby residents. The specific effective blocking distance depends on the layout and size of the examination venue. It is crucial to tailor the installation to the specific requirements of each examination room to ensure optimal signal blocking.
Stability of Jamming Effect:
During the examination process, it is essential to maintain a consistent and uninterrupted signal blocking effect. Any intermittent disruptions could potentially allow candidates to exploit brief moments of connectivity for cheating purposes. Therefore, the stability of the jamming effect is of utmost importance. Schools must ensure that the Signal Jammers operate continuously throughout the entire examination period, providing a reliable shield against unauthorized communication.
One of the key advantages of Signal Jammers is their silent operation. These devices operate at low frequencies, resulting in no noise generation. This eliminates concerns about disturbing candidates during the examination. Furthermore, Signal Jammers comply with national safety standards regarding radiation levels, ensuring that invigilators and candidates are not exposed to any harmful effects.
The increasing prevalence of 5G smartphones has raised concerns about cheating during examinations. To address this issue, schools have installed Signal Jammers to block unauthorized communication devices. By considering factors such as frequency band blocking, effective blocking distance, and stability of the jamming effect, schools can create a fair and secure testing environment. The non-disruptive operation and compliance with safety standards further ensure the well-being of invigilators and candidates. With the deployment of Signal Jammers, schools can uphold the integrity of examinations and promote academic honesty.
