When customers call us to express their needs, they often start by stating their purchasing intentions. For example, they may require a high-power backpack signal jammer to solve the signal jamming issue in an entire building. They also need us to advise on the installation location for this signal jamming device. However, it is important to understand the specific conditions of the project site, as the recommended solution may differ significantly from the customer’s initial expectations.
Why we don’t recommend using high-power backpack signal jammers indoors:
To address signal jamming in an entire building, it is essentially targeting the indoor environment of the building. If a building has several independent rooms, the best solution is to use multiple low-power Cell Phone Jammers in a cellular network coverage format. High-power backpack signal jammers are primarily used to solve signal jamming in outdoor or open areas. It is generally recommended to install high-power Cell Phone Jammers at a high position to achieve maximum transmission distance. Only when the installation height is sufficiently high can the signal transmission overcome obstacles and extend the jamming range. However, once it encounters large buildings during transmission, the signal jamming will essentially cease.
The problem with using high-power backpack signal jammers to solve signal jamming in a building:
First and foremost, it is crucial to understand that high-power signal jamming devices cannot be installed inside the building itself to cover the signal jamming in the entire building. The dense walls inside the building will severely affect the transmission of the jamming signal, making it impossible to directly cover the upper and lower floors of the building. Even the number of rooms that can be covered on the same floor will be extremely limited. Some may wonder if installing the high-power Cell Phone Jammer directly on the rooftop of the building would work. Unfortunately, this is not the case. If it is installed in the central position of the rooftop, the jamming signal will mainly affect only the top of the building and the surrounding areas. The reinforced concrete walls on the rooftop will prevent the jamming signal from transmitting to the rooms below.
The best solution:
If it is determined that a high-power backpack signal jammer must be used to solve signal jamming in a building, there is still a solution, but it is almost impossible to use only one set of high-power jamming devices. Instead, at least two or even more sets of high-power Cell Phone Jammers need to be used in combination. The specific implementation method is to install one set in front of the building and another set at the back, at a distance of approximately 20-30 meters from the building. It is also preferable to install them at a height that reaches half of the building’s height. If the length of the building exceeds 50 meters, the number of installed jamming devices needs to be increased.
Conclusion:
When it comes to solving signal jamming in a building, it is important to consider the specific conditions of the project site. While high-power backpack signal jammers are effective in outdoor or open areas, they are not suitable for indoor environments. Instead, a combination of multiple low-power Cell Phone Jammers in a cellular network coverage format is the best solution for addressing signal jamming in a building. By understanding the limitations and implementing the appropriate solution, we can effectively solve the signal jamming issue and ensure smooth communication within the building.
