Cell phone also known as mobile phones produce both electronic magnetic fields and radiowaves (microwaves). Most cell phone shielding devices are designed to reduce the radiowaves.
Cell phones emit low frequency magnetic fields that are measured in milliGauss, also they emit high frequency microwave radiation which is a concern to the public and to their health. That is why people have came up with solutions like mobile phone shields.
Anti-radiation technology utilizes multiple layers of shielding to block harmful Electromagnetic Radiation (EMF) from cell phones.
If you are curious about the anti shield cell phone products we will cover them in a later post.
