All customers who have purchased a wireless signal blockers are very concerned about the actual shielding effect of the shielding device when they perform a power-on test after receiving the product. Different customers must have differences due to the testing environment, testing methods and testing times. The cell phones used are also different, so the test results fed back will be greatly different. The placement or installation location of shielding equipment is also a key factor affecting the shielding effect. Then the question arises, if the wireless signal jammer is placed directly on the ground, how effective will it be?

Usually when manufacturers of wireless signal jammers sell shielding equipment, there will be a detailed installation and use instructions in the packaging box. Let’s take the most common low-power wireless signal jammer used in indoor environments as an example. There should be special installation instructions in its instruction manual. The first choice is wall-mounted installation. It is recommended that users keep the installation height of the shielding device between 1.8 meters and 2.5 meters, because this height is exactly at a position where human hands cannot reach it, thus preventing future use. Some people will maliciously damage the shielding equipment or artificially cut off the power or shut down the equipment. At the same time, this installation height also exceeds the height of almost all furniture, tables, chairs, or other furnishings in the room. This allows the shielded signal of the cell phone signal jammer to be transmitted unimpeded, maximizing the coverage of the shielded signal to everyone in the room. corner.

If it is not convenient to wall-mount the device, but to place the cell phone jammer directly on the desktop, this can be regarded as a compromise method of use and is suitable for short-term, temporary use scenarios. Since the conventional desktop height is about 0.8 meters, if the wireless signal jammer is placed directly on the desktop, the shielded signal will be more or less affected by some furniture or furniture with a height of more than 1 meter during the transmission to the surroundings. The influence of obstacles will actually reduce the final shielding effect.

Finally, let’s analyze what will happen if the wireless signal jammer is placed directly on the ground: Unless the room is completely empty, tables, chairs or furniture in the room will become obstacles in the process of shielding signal transmission. , it will more or less attenuate the shielding signal, and this attenuation will be superimposed as the number of obstacles increases. This will seriously affect the shielding distance of the wireless signal jammer. Placing the shielding device on the ground for testing and use is the most undesirable way of use.
