Some customers will mention such a question: a 6-story teaching building, each floor is about 1,500 square meters, whether 1-2 high-power cell phone signal jammers can achieve cell phone signal shielding for the entire teaching building.

Nanjing Bokang Electromechanical Technology Co., Ltd. does not recommend the use of high-power cell phone signal jammers to shield a 6-story teaching building. This idea is understandable. After all, the number of jammers used is small and it is easy to install.

Why is it not recommended to use high-power cell phone signal jammers to shield a 6-story teaching building? There are several reasons

12 Bands Signal Jammer
1. It is recommended to use stairs below the 4th floor to shield the entire teaching building. Above the 4th floor, the signal transmitted by the base station to the teaching building will reduce most of the obstructions, so the cell phone signal strength transmitted to the high floors above the 4th floor of the teaching building will be higher than that of the lower floors. This will increase the difficulty of shielding, and considering that the shielding signal of the high-power cell phone signal jammer takes into account both the upper and lower floors, the installation location is generally not more than 2 floors high, which is about 6-9 meters. The higher the installation location, the greater the difficulty of installation, and safety is also a problem to be considered.

For teaching buildings below 2 or 4 floors, when configuring high-power cell phone signal jammers, they also need to be installed in front and behind the teaching building respectively, and the number of configurations should be determined according to the cell phone signal strength on site. Under normal circumstances, at least 2 units are required in front and back, a total of 4 high-power mobile phone signal jammers. The cost of high-power cell phone signal jammers is much higher than that of low-power cell phone signal jammers.

Therefore, in summary, it is not recommended to use high-power cell phone signal jammers in a 6-story teaching building. The most cost-effective way is to install a low-power cell phone signal jammer in each classroom, and it can also be connected to the Internet and uniformly controlled and managed through software.
