However, in some cases, we may want to block cell phone signals in order to protect personal privacy or maintain a quiet environment. That's when you need to use a cell phone blocker. This article will discuss the functions, principles and methods of use of mobile phone signal blockers.
Function of cell phone signal blocker
Cell phone signal blocker, as the name suggests, is a device used to block cell phone signals. It can effectively prevent the communication between the mobile phone and the base station, so that the mobile phone can not receive or send signals, thus playing the role of shielding communication. Cell phone signal blockers are usually used in conference rooms, prisons, exam rooms and other places that need to keep quiet or prevent communication.
The principle of cell phone signal blocker
The working principle of the mobile phone signal blocker is mainly to interfere with the mobile phone signal by transmitting a specific frequency of electromagnetic waves. It sends a signal around at the same frequency as the phone's signal, but with greater intensity, causing the phone to not communicate properly. This interference will force the phone to constantly switch signals, eventually making it unable to connect to the base station, achieving the effect of signal shielding.
