Signal jammers are a type of equipment specifically used to shield wireless signals. Their main function is to prevent terrorists or other criminals from using wireless remote control bombs, walkie-talkies, mobile phones, drones and other equipment to carry out terrorist attacks or other criminal activities. In order to ensure that the signal jammer can perfectly complete the tasks assigned by superiors when shielding wireless signals, and in the absence of casualties, the requirements for the jammer to shield the wireless signals of the hand are extremely high. So, what factors can affect the shielding effect of the signal jamming device?

1. Transmission power of the RF module: The greater the transmission power of the RF module, the greater the shielding range. Therefore, when selecting an RF module, a high-power RF module should be given priority. However, if the bandwidth of the signal transmitted by a single module is too wide, it will also affect the shielding effect. Therefore, the bandwidth of the frequency of the signal transmitted by a single module is reasonably allocated, and the shielding range is maximized through reasonable bandwidth allocation.

2. Signal strength at the use site: Signal strength refers to the strength of the mobile phone signal. The signal strength of the mobile phone depends on the distance from the mobile phone base station. The intensity of the signal output signal of the signal jammer module can be controlled. The distribution of the spectrum can be measured by a spectrum analyzer, and then the shielding range can be maximized by setting a specific module. Of course, you can also negotiate with the operator in advance to reduce the mobile phone signal strength on site. The strength of other remote control signals depends on the signal jammer, which is a device specifically used to shield wireless signals. Its main function is to prevent terrorists or other criminals from using wireless remote control bombs, walkie-talkies, mobile phones, drones and other equipment to carry out terrorist attacks or other criminal activities. In order to ensure that the signal jammer can perfectly complete the tasks assigned by superiors when shielding wireless signals, and in the absence of casualties, the requirements for the jammer to shield the hand wireless signal are extremely high. So, what factors can affect the shielding effect of the jammer?

The signal strength of a mobile phone depends on the distance from the mobile phone base station. The strength of the signal output signal of the signal jammer module can be controlled. The distribution of the spectrum can be measured by a spectrum analyzer, and then the shielding range can be maximized by setting a specific module. Of course, you can also negotiate with the operator in advance to reduce the mobile phone signal strength on site. The strength of other remote control signals depends on the distance between the signal source and the suspected explosive, which is unpredictable. Therefore, the focus should be on shielding the remote control signal, and the shielding wireless signal module of the signal jammer should be set to seamless interference.

3. Weather and environmental factors: Weather and environmental factors will also affect the shielding effect of the jammer. For example, rainy and foggy days will affect the transmission of wireless signals, thereby affecting the shielding effect of the jammer. In addition, obstacles such as buildings, hills, and trees will also affect the transmission of wireless signals, thereby affecting the shielding effect of the jammer. Therefore, when choosing the place to use the jammer, these factors should be considered and open places should be selected as much as possible.

4. The equipment quality of the signal jammer: The equipment quality of the signal jammer will also affect its shielding effect. If the equipment quality of the signal jammer is not good, its shielding effect will also be affected. Therefore, when choosing a jammer, you should choose equipment with good quality and stable performance.

5. How to use the signal jammer: The method of using the signal jammer will also affect its shielding effect. If the method of use is incorrect, then its shielding effect will also be affected. Therefore, when using the jammer, you should operate it according to the requirements of the operation manual, and it should be operated by professionals.

In short, the shielding effect of the portable cell phone jammer is affected by many factors. In order to ensure the best shielding effect of the jammer, you should choose equipment with good quality and stable performance, and you should operate it according to the requirements of the operation manual. In addition, weather and environmental factors should be considered, and open places should be selected as much as possible.
