    Current Status and Future Development of Mobile Phone Signal Shield in Examination Stage

    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...
