When it comes to exam room cell phone signal jammers, many school administrators will ask if one or two high-power models can cover the entire school exam room, thinking that a small number of devices will be easier to install and operate, but the reality is very different from the ideal situation.
High-power signal jammers do have strong transmission capabilities and wide signal coverage, but it is important to understand that these devices are not suitable for the controlled environment of school exam rooms. First, they are mainly used in outdoor environments. Second, their wide coverage means that the transmission distance is long under unobstructed conditions. However, when there are signal obstacles such as walls and buildings, the signal will be greatly attenuated and large-scale coverage cannot be achieved. School exam rooms consist of multiple floors and classrooms with partitions, and the environment lacks transparency and visibility.
In addition, assuming that high-power cell phone signal jammers are selected for the exam room, installation and operation are not easy. In fact, the equipment should not be installed inside the building or on the roof to avoid being blocked and attenuated by walls and floors. Instead, high-power jammers need to be placed at an appropriate distance in front of or behind the building. In addition, the device should not be simply placed on the ground, but the antenna of the mobile phone signal jammer should be raised to a certain height, such as at least 2-3 floors. In addition, considering the possibility of thunderstorms, lightning protection and waterproofing measures must be added when installing the shielding equipment.
Based on the above analysis and suggestions, it is obvious that high-power models are generally not recommended for mobile phone signal jammers in examination rooms.
