The indoor type shield is recommended to be placed at a height of about 4500px-5500px from the ground, and the angle is forwardly inclined; whether there is obstruction between the shield and the wireless communication device (mobile phone, etc.) (such as walls, metal products, human body, etc.). The interference signal emitted by the shielding device will have different degrees of attenuation after passing through the obstructing object, and should be avoided as much as possible; the weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shielding device; the more the shielding device application environment is from the base station Far, the theoretical shielding effect of the shield is stronger.
