Every few months before the college entrance examination and high school entrance examination, many school customers ask us about test room radio jammers. In the process of product consultation and understanding, there is a problem that customers often mention. This problem is: just want to buy a Two high-power examination room radio jammers can cover the shielded signal to all examination rooms in the school. Customers think that it will be easy to install and operate due to the small number of devices, so is this really the case?

To use a common saying: ideals are plump, reality is skinny! It is true that the high-power signal shielding device has a large transmission power and a large signal coverage, but what needs to be known is that the high-power signal shielding device is actually not suitable for the examination room environment of the school. First: its main application scenario refers to the outdoor environment. Second: Its coverage is large, which also means that the transmission distance is large in a visual environment (without obstacles). If the shielded signal has obvious obstacles in the transmission path, such as walls, buildings, etc., the signal will be attenuated. The degree will be very large, and it will not be possible to achieve a wide range of signal coverage. The school's examination room is obviously composed of various floors and classrooms, and there are partitions between them. This is not a transparent, visible environment.

Furthermore, if the test room radio jammer is selected as a high-power model, it cannot be simply considered that its installation and operation are very easy and convenient. In fact, the installation location of the high-power radio jammer must not be selected in the building or on the roof, because it is necessary to avoid the blocking and attenuation of the shielded signal by the walls and floors of the building. In the actual application process, the high-power radio jammer needs to be installed at a suitable distance in front of or behind the building, and usually it is not simply to place the shielding device directly on the ground, but the radio jammer should be installed. The antenna of the device should be erected to a certain height, such as at least 2-3 floors. In addition, it is also necessary to consider that the equipment may encounter thunderstorms during the use process, so it is inevitable to consider the installation of lightning protection and waterproof protection measures for the shielding equipment.
