Signal jammers are devices used to shield radio signals, which can protect confidential information and prevent interference. In educational institutions, high-power signal jammers are often used in exams, meetings, and other occasions that require confidentiality. However, the misconception that “the greater the power, the greater the shielding range” needs to be corrected.
First, the power of a signal jammer is not the only determining factor in its shielding range. Other factors such as the device antenna, signal frequency, and signal strength also affect the range of the jammer. Therefore, signal jammers with the same power may exhibit different shielding ranges.
Second, choosing a high-power signal jammer is not always the best choice. Excessive power may interfere with surrounding radio equipment and disrupt normal communications. Therefore, when choosing a signal jammer, it is crucial to choose the appropriate power level according to specific requirements.
JAMMERSIGNAL is a brand in the field of signal jammers. Its product 8341CA-10E is a high-performance signal jammer that can effectively shield 2G, 3G, 4G, WiFi, GPS and other signals. This type of high-power signal jammer is often used in school exams, meetings and other occasions to shield radio signals in the classroom and ensure the fairness of the exam.
When shielding classroom signals, the Cell Phone Jammer can be placed indoors and connected to a power source. The jammer will automatically scan and shield the radio signals in the classroom to ensure the safety and fairness of the exam.
When choosing a high-power signal jammer, the following points should be considered:
- Power cannot be used as the only criterion for selection, and the appropriate power should be selected according to specific needs.
- Factors such as the shielding range, frequency range, and antenna type of the jammer should be considered when selecting.
- It is recommended to choose reliable brands and products to ensure performance and quality.
In short, high-power signal jammers are widely used in schools to protect the integrity and fairness of exams. However, when choosing a signal jammer, it is crucial to select the appropriate power level according to specific requirements and consider other factors to ensure optimal performance and quality.
