The Importance of Using High and Low Power Prison Jamming Devices

In recent years, the use of prison jamming devices has become increasingly prevalent in correctional facilities. These devices are designed to block unauthorized cell phone signals within the prison walls, ensuring the safety and security of both inmates and staff. However, it is crucial to understand the differences between high and low power jamming devices and their impact on signal interference. This article aims to shed light on the importance of using both types of devices in conjunction to effectively address signal blind spots within correctional facilities.

The Impact of High Power Jamming Devices:

Generally, prison jamming devices are available in a few high power models. In theory, high power amplifiers emit stronger radiation. While these devices offer a larger shielding radius, they may inadvertently interfere with areas that should not be blocked. This interference can be attributed to the extensive coverage area of high power devices, which may extend beyond the intended boundaries of the correctional facility.

The Prevalence of Prison Jamming Devices:

Prison jamming devices are predominantly used in prisons and correctional facilities due to their ability to cover large areas. These devices are highly favored by customers as they require minimal installation and are easy to manage. However, within the confines of prison walls, the density of buildings and the composition of walls can affect the effectiveness of signal blocking, resulting in blind spots. To address this issue, it is recommended to simultaneously use high and low power jamming devices within correctional facilities. By utilizing low power devices in areas with signal blind spots, the problem of interference can be effectively resolved.

The Impact on Cell Phone Signals:

Within the range of signal blocking, cell phones may display full signal bars, giving the impression of strong connectivity. However, in reality, these devices will not be able to establish any communication. The use of prison jamming devices does not interfere with the functionality of other electronic devices. This is because the electromagnetic signals emitted by these devices strictly adhere to the frequency bands regulated by the government, only disrupting cellular communication.


In conclusion, the use of prison jamming devices is crucial in maintaining the security and order within correctional facilities. However, it is essential to consider the differences between high and low power devices and their impact on signal interference. By employing a combination of high and low power jamming devices, correctional facilities can effectively address signal blind spots and ensure uninterrupted communication within authorized areas. It is imperative to strike a balance between signal coverage and interference to maximize the effectiveness of prison jamming devices.
