Cell phone signal jammers are devices used to block or interfere with cell phone signals in certain areas, such as examination halls. When selecting a cell phone signal jammer, one important consideration is the style of the device, which can be categorized into two types: built-in antenna and external antenna. This article will discuss the advantages of choosing a built-in antenna and the different usage methods for cell phone signal jammers.
Advantages of Built-in Antenna:
When a cell phone signal jammer is permanently installed in an examination hall, opting for a built-in antenna offers several benefits. Firstly, the built-in antenna provides better protection against damage compared to an external antenna. External antennas are exposed and can easily be unscrewed or have their internal components damaged, rendering the signal jammer ineffective. Additionally, built-in antennas are more aesthetically pleasing as they are installed inside the examination hall, seamlessly blending into the environment.
Different Usage Methods:
Depending on the intended usage, there are two common methods for utilizing cell phone signal jammers. The first method involves permanently installing the jammer in the examination hall, while the second method entails using the jammer during exams and collecting it afterwards for centralized storage.
Challenges of External Antenna:
For cell phone signal jammers with external antennas, the process of collecting them after exams can be cumbersome. Since signal jammers consist of multiple modules, they are equipped with multiple antennas. During collection, all the antennas need to be unscrewed and placed back into the jammer’s packaging. In contrast, signal jammers with built-in antennas only require the main unit and power cord to be collected. The power cords are standardized, making replacement or loss of cords a simple and convenient process.
Simplified Operation with Built-in Antenna:
By choosing a cell phone signal jammer with a built-in antenna and opting for permanent installation in the examination hall, the tedious process of collecting the jammer after exams is eliminated. This not only saves time but also streamlines the device inspection procedures.
Conclusion:
In conclusion, selecting a cell phone signal jammer with a built-in antenna and opting for permanent installation offers convenience and simplicity, particularly in examination halls. It reduces unnecessary steps and significantly saves time during device inspections. Additionally, the built-in antenna provides better protection against damage and enhances the overall aesthetics of the environment.
