Cell Phone Jammers have become a popular tool for disrupting cell phone signals in various settings. However, when it comes to interfering with a 6-story teaching building, using a high-power Cell Phone Jammer is not recommended. This article will explore the reasons behind this recommendation and propose a more cost-effective alternative.
Reasons for Not Using High-Power Cell Phone Jammers:
Signal Transmission Difficulties:
Using a high-power Cell Phone Jammer to interfere with an entire teaching building is more suitable for buildings with 4 floors or less. This is because, in buildings higher than 4 floors, the signal transmitted by the base station experiences reduced obstruction, resulting in slightly stronger signal strength on higher floors compared to lower floors. Consequently, interfering with higher floors becomes more challenging. Additionally, the installation of high-power Cell Phone Jammers is typically limited to a height of 6-9 meters, equivalent to approximately 2 floors. Installing them at higher positions increases the installation difficulty and raises safety concerns.
For teaching buildings with 4 floors or less, the installation of high-power Cell Phone Jammers requires separate installations in the front and back of the building. The number of jammers needed should be determined based on the signal strength at the site. In general, a minimum of 2 jammers is required for both the front and back of the building, totaling 4 high-power Cell Phone Jammers. However, in buildings higher than 4 floors, the reduced obstruction of the base station’s signal transmission to the teaching building results in slightly stronger signal strength on higher floors compared to lower floors. This further complicates the interference process. Moreover, considering the need for the interference signal to cover both upper and lower floors, the installation of high-power Cell Phone Jammers is typically limited to a height of 6-9 meters, making installation at higher positions more difficult and raising safety concerns.
Considering the aforementioned reasons, it is not advisable to use high-power Cell Phone Jammers in a 6-story teaching building. Instead, a more cost-effective approach would be to install a low-power Cell Phone Jammer in each classroom, which can also be connected to the internet for centralized control and management. This solution offers the highest cost-effectiveness while effectively addressing the issue of signal interference in the teaching building.
