How to maximize the shielding range of the police shielding device?

The police usually use some police jammers to cooperate with the task of handling some illegal assemblies, mass gatherings, temporary communication control, and arresting criminal suspects. Because some places of use are different and the strength of the wireless signal at the mission site is different, the shielding range of the police signal jammer will also be different. By setting up the police jammer and setting the parameters of the police jammer, the range of the wireless signal shielding of the police jammer can be further effectively improved. The following will introduce several methods for the police shielding device to maximize the shielding range in different places.

6 Bands Signal Jammer

First, in order to allow the police jammer to shield a larger range, the police jammer can be placed as close as possible to the key areas of the mission site after arriving at the mission site, for example, when removing remote control bombs, or in the arrest of criminal suspects. In the middle, you can try to put the police jammer as close as possible to the position of the remote control bomb, or as close as possible to the suspect's position without alerting the suspect, so that the target area or person can be shielded more effectively.

Second, due to the limitations of the on-site environment, the police jammer cannot be placed close to the task site, so the police jammer can be placed as high as possible. The advantage of placing it at a high place is to reduce unnecessary obstructions. If the interference signal emitted by the police jammer can be directly and unobstructed to the mission site, it will be helpful to improve the shielding range of the police jammer.

Third, with the spectrum analyzer, the test place uses the frequency parameters of the mobile phone signal on site. According to the frequency parameters of the mobile phone signal, the frequency parameters of the radio frequency module corresponding to the police jammer are set to improve the performance of the police jammer. Block range. Note that when setting the frequency parameters of the RF module, you need to add 2-3MHz before and after the frequency range to avoid the frequency offset of the RF module during output.

The above three methods are suitable for different places of use. Through these three methods, the interference range of the police shielding device in different use environments can be squeezed to the greatest extent.
