In addition to the mobile phone signal shielding device, what other devices can also be used as shielding devices?
Shielding equipment is a general conceptual term. Equipment that can shield signals or block wireless signal transmission (signal attenuation) can be called "shielding equipment". Of course, the mobile phone signal shielding device also belongs to a kind of shielding equipment. So in addition to this, what types of equipment or products are also classified as shielding equipment?
In general, shielding equipment can be divided into two categories: the first category belongs to the category of electronic instrument products, which refers to electronic products that achieve shielding by transmitting shielding signals (interference signals). The aforementioned mobile phone signal shielding instruments belong to this category. Classes, as well as mobile phone jammers, signal jammer, frequency jammers, etc., are all classified as shielding equipment in the category of electronic products.
The second category is products belonging to materials science, which refers to structural products made of materials and materials with strong RF signal attenuation capabilities, such as shielding boxes and shielding cabinets made of shielding nets, metal isolation plates, etc. When in these shielding boxes and shielding cabinets, the wireless signal is greatly attenuated, and it has a certain shielding effect. Therefore, such products can also be called shielding equipment.
