Does the greater the power of the signal jammer, the greater the shielding range?

A signal jammer is a device used to shield radio signals, which can prevent the transmission of radio signals, thereby protecting confidential information and preventing interference. In schools, high-power signal jammers are widely used in exams, meetings and other occasions that require confidentiality. However, many people think that the greater the power, the greater the shielding range, this view is wrong.

First of all, the power of the signal jammer is not the only factor that determines its shielding range. The shielding range of the signal jammer is also affected by other factors, such as the device's antenna, signal frequency, signal strength, etc. Therefore, even signal jammers with the same power may have different shielding ranges.

Secondly, a high-power signal jammer is not necessarily the best choice. If the power of the signal jammer is too large, it may interfere with the surrounding radio equipment, thereby affecting normal communication. Therefore, when selecting a signal jammer, it is necessary to select an appropriate power according to actual needs.

Chengdu 8341 is a brand specializing in the production 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. In schools, high-power signal jammers are widely used in exams, meetings and other occasions that require confidentiality. It can effectively shield the radio signal in the classroom, thus protecting the safety and fairness of the exam.

If the school needs to shield the signal of a classroom, the signal jammer can be placed in the classroom and connected to the power supply. The signal jammer will automatically scan and block radio signals in the classroom, thus protecting the safety and fairness of the exam.

When choosing a high power jammer, you need to pay attention to the following points:

1. Power is not the only selection factor, you need to choose the appropriate power according to actual needs.
2. When selecting a signal jammer, factors such as its shielding range, frequency range, and antenna type need to be considered.
3. When choosing a signal jammer, you need to choose a reliable brand and product to ensure its performance and quality.
In short, high-power signal jammers are widely used in schools and can effectively protect the safety and fairness of exams. However, when choosing a signal jammer, it is necessary to choose the appropriate power according to the actual needs and consider other factors to ensure its performance and quality.
