Exploring the Differences in Power and Coverage for Signal Jamming Devices
Signal jamming devices are widely used in various settings to block or disrupt wireless communication signals. The range and effectiveness of these devices depend on their power output, making them suitable for specific environments such as prisons, exam halls, or classrooms. This article aims to shed light on the differences in power and coverage for signal jamming devices and their appropriate applications.
Power and Coverage Variations:
The range of signal jamming devices varies depending on the power output of the device. High-power signal jammers used in correctional facilities, for example, can cover a shielding radius of several hundred meters. On the other hand, low-power signal jamming devices commonly used in exam halls or conference rooms typically have a shielding radius ranging from 1 to 10 meters. The actual coverage also depends on the strength of surrounding signal communication base stations.

High-Power Signal Jamming Devices:
High-power signal jamming devices possess exceptional shielding capabilities, with power outputs reaching several hundred watts. These devices are suitable for unique locations such as prisons or correctional facilities. However, due to their strong shielding capabilities, they may inadvertently affect the normal mobile voice communication requirements in nearby residential areas. Therefore, these signal jamming devices are generally deployed in spacious areas far away from residential zones to minimize any potential disruptions to the surrounding environment.
Low-Power Signal Jamming Devices:
In contrast, low-power signal jamming devices are more suitable for classroom settings. If a school campus has a communication base station and the mobile devices receive pulse signals equal to or greater than -90dBm, the signal jamming device will effectively block signals within a 10-meter radius. In such cases, having one signal jamming device per classroom is sufficient to ensure a disturbance-free environment.
Signal jamming devices play a crucial role in maintaining security and order in various settings. Understanding the differences in power and coverage is essential for selecting the appropriate device for specific environments. High-power signal jammers are ideal for locations like prisons, while low-power devices are more suitable for classrooms. By considering the power output and coverage range, signal jamming devices can be effectively deployed to meet the specific needs of different environments while minimizing any unintended disruptions.
