Upgrading Prison Signal Jammers: Considerations for Power Adjustment in 5G Models

With the widespread adoption of 5G technology, many prisons have begun the process of upgrading their signal jammers. During the upgrade process, customers often inquire about the inclusion of power adjustment functionality in the new 5G signal jammers. This article explores the two main types of prison signal jammers and discusses the importance of power adjustment in their selection.

Types of Prison Signal Jammers:

Prison signal jammers can be broadly categorized into two types: low-power 5G signal jammers and high-power prison signal jammers. In China, considering the proximity of prison facilities to nearby base stations, the signal strength received within prisons is generally strong. Therefore, it is crucial to select the appropriate type of signal jammer based on the specific requirements and considerations.

Low-Power 5G Signal Jammers:

Over the past decade, feedback from the application of low-power 5G signal jammers has indicated that their signal coverage range is often not ideal. Customers have expressed a preference for higher power output in these models. Considering the close proximity of base stations to prisons, the signal strength received within prison walls is relatively strong. Additionally, the installation and testing of signal jammers require the consideration of multiple mobile network standards and frequency bands. Therefore, when selecting low-power models, power adjustment functionality can be disregarded as these signal jammers can operate at maximum output power. The recommended model for this category is the SMa-818B5 5G signal jammer.

High-Power Prison Signal Jammers:

In contrast, high-power prison signal jammers require careful consideration of signal coverage direction and power adjustment due to their potential impact on areas beyond the prison perimeter. Customers who desire power adjustment functionality while ensuring that the external adjustment switch of the 5G signal jammer cannot be tampered with maliciously can opt for the SMa-818B5-PLUS Network Edition. This model allows remote adjustment of the output power for any frequency band within each 5G signal jammer unit.


In summary, the decision to include power adjustment functionality in the selection of prison signal jammers during the upgrade to 5G models depends on the specific requirements. For low-power models, power adjustment can generally be disregarded as they operate at maximum output power. However, for high-power models, power adjustment is crucial to prevent excessive signal interference in unrelated areas outside the prison. By considering these factors, prison authorities can make informed decisions when upgrading their signal jamming systems.
