In the handling of illegal gatherings, mass gatherings, temporary communication control, and apprehension of criminal suspects, the police often utilize police signal jammers to assist in their tasks. However, due to variations in usage locations and the strength of wireless signals at the scene, the shielding range of police jammers may differ. By adjusting the installation method of police signal jammers and the parameter settings of police signal blockers, the range of wireless signal interference can be effectively enhanced. This article will introduce several methods to maximize the shielding range of police signal jammers in different environments.
Subtitle 1: Placing the Jammer in Key Areas
To expand the shielding range of police signal jammers, it is advisable to position the police signal blocker as close as possible to the critical areas of the scene upon arrival. For instance, in operations involving the disposal of remote-controlled bombs or the apprehension of criminal suspects, placing the police signal jammer near the location of the remote-controlled bomb or in proximity to the suspect, without alerting them, can effectively shield the target area or individual.
Subtitle 2: Utilizing Elevated Positions
In situations where it is not feasible to position the police signal jammer near the scene due to environmental constraints, placing the jammer at a higher elevation can be advantageous as it reduces unnecessary obstructions. If the interference signals emitted by the police signal blocker can be transmitted directly and unobstructed to the scene, it can help enhance the shielding range of the police signal jammer. This method can be particularly useful in operations involving the disposal of remote-controlled bombs or the apprehension of criminal suspects.
Subtitle 3: Coordinating with Spectrum Analyzers
By using a spectrum analyzer to test the frequency parameters of the mobile signals present at the scene, it is possible to adjust the corresponding frequency parameters of the RF module of the police signal blocker. This adjustment can help enhance the shielding range of the police signal jammer. It is important to add an additional 2-3MHz to the frequency range before and after setting the frequency parameters of the RF module to prevent frequency deviation during output. By employing these three methods, the interference range of police signal jammers can be maximized in different usage environments.
In the realm of law enforcement, the effective utilization of police signal jammers is crucial in handling various situations. By implementing the methods mentioned above, such as placing the jammer in key areas, utilizing elevated positions, and coordinating with spectrum analyzers, the shielding range of police signal jammers can be significantly enhanced. This ensures the successful execution of tasks related to illegal gatherings, mass gatherings, temporary communication control, and the apprehension of criminal suspects.
