The effective shielding range of a signal jammer depends on various factors that need to be considered before purchasing. Here are the key factors to consider:
1.Power of the signal jammer:
The power output of the signal jammer plays a vital role in determining its effective shielding range. It is worth noting that some signal jammers on the market may claim to have high power, such as 5W, but the actual power output may be much lower, even less than 1W. Generally speaking, low-power signal jammers within 1W can provide a shielding range of about 1-10 meters, covering an area of ​​10-30 square meters. But it is important to remember that such low-power jammers cannot penetrate walls.
2.Base station density:
The presence and density of nearby base stations can also affect the performance of the signal jammer. If there are multiple base stations within a 100-meter radius, purchasing a low-power signal jammer may not produce the expected effect, especially if the base station signal is strong. In this case, it is recommended to choose a signal jammer with slightly higher power, about 2W per channel. It is worth noting that in rare cases, if there is a mobile base station on the customer’s roof, it becomes extremely challenging to effectively shield the signal, and a high-power jammer may be required to solve this problem.
3.Environmental barriers:
The physical environment in which the jammer is installed, especially the type of walls that exist, can affect its performance. Jammers may have difficulty penetrating concrete walls or glass partitions. Customers often ask how to shield signals through partitions, especially when it comes to children playing games in separate rooms. Achieving effective shielding in this situation can be difficult and costly, as specialized jammers that can penetrate walls are expensive, often exceeding $700.
In summary, the effective shielding range of a cell phone jammer is affected by a variety of factors. It is recommended to use a field wall instrument to evaluate the signal level in the installation environment before purchasing in bulk. In addition, testing jammers with different power outputs and observing their performance can help determine the best option for your specific needs.
