Factors Affecting the Range of Signal Jammers

Understanding the Key Factors for Effective Signal Jamming

1. Distance between the Venue and Base Stations:

If you purchase a low-power Signal Jammer and there is a base station within 100 meters, it will have minimal or no effect on blocking signals. This is because the signal strength of the base station is too strong. In such cases, it is advisable to consider purchasing a medium or high-power jammer.

2. Surrounding Environment:

The surrounding environment plays a crucial role in determining the effectiveness of a Signal Jammer. Factors such as the type of walls (concrete, glass partitions, or metal) where the jammer is installed can significantly impact its performance. Generally, Signal Jammers experience significant signal loss when passing through walls.

Considering the factors mentioned above, it is clear that the range of a Signal Jammer is not determined by a single factor alone. To ensure the effectiveness of your jammer, it is recommended to use signal testing equipment to assess the signal strength in your installation environment. Alternatively, you can seek assistance from our technical experts who can provide you with a suitable solution.


Signal Jammers are essential tools to maintain fairness during large-scale exams. However, their effectiveness depends on various factors, including the distance between the venue and base stations, as well as the surrounding environment. To make an informed purchase decision, it is advisable to test the signal strength in your installation environment or consult our technical team for expert guidance.
