If the shielding distance of the smart shield is short, it is because the base stations around the shielding site are close, which results in the shielding distance of the signal shield is not ideal. General smart shield, its shielding principle, generally speaking, is the power suppression of white noise, which means which device emits the power in this place, who has the best effect. For example...

Radio transmission uses electrical signals as message carriers, and high frequency radio electromagnetic waves are mainly transmitted by the ionosphere. Electrical signal interference (ESI) is an electronic noise that interferes with cable signals or even reduces the integrity of wireless signals. ESI is usually generated by a signal radiator device. There are also conduction interference and radi...
