In some standardized examination venues, there is a special requirement for the appearance of the signal jamming devices used. This includes the need for indicator lights on the device’s casing, with each frequency band having a corresponding working indicator light. This requirement is often imposed by manufacturers of certain types of signal jammers to control bidding or exclude other similar products. However, it is important to carefully evaluate the functionality of these indicator lights to ensure their effectiveness.
The Issue with Indicator Lights:
For example, consider the most common type of signal jammer used in examination venues, which is equipped with 5G signal blocking capabilities. Typically, these devices are configured with 12 signal jamming modules, each corresponding to a working indicator light. Additionally, there should be at least one power indicator light for the main host. However, upon closer inspection, it becomes unclear what purpose these 13 indicator lights serve.
The Role of Indicator Lights:
The power indicator light is self-explanatory, as it remains constantly lit when the signal jammer is powered on. However, the remaining 12 indicator lights are meant to provide feedback on the working status of the signal jamming modules. Unfortunately, some manufacturers may simply connect these lights to the power indicator of each module, indicating only that the modules are receiving power. This does not necessarily indicate whether the modules are functioning properly.
The Limitations of Indicator Lights:
While the indicator lights may suggest that all modules are working, it does not guarantee their actual functionality. For instance, a module may receive power but have a faulty signal source or amplifier component, resulting in no signal blocking. However, since the indicator light remains lit, customers are unable to identify the true status of each module within the signal jamming device.
The Need for Caution:
It is not advisable to have excessive indicator lights on examination venue signal jammers. Firstly, having too many lights does not accurately represent the status of each module unless a dedicated circuit for fault detection and analysis is implemented. As a supporting product for standardized examination venues, it is important not to make these devices overly conspicuous. If multiple lights are constantly lit or frequently flashing due to malfunctions, it can distract and disrupt the attention of students during exams.
While the inclusion of indicator lights on signal jamming devices used in standardized examination venues may seem beneficial, it is crucial to evaluate their functionality. Merely having indicator lights does not guarantee the proper functioning of each module. Therefore, it is important for manufacturers to implement reliable fault detection and analysis circuits to provide accurate feedback on the status of signal jamming modules. This will ensure the effectiveness of these devices in maintaining a fair and secure examination environment.
