Jammer-Mart November 2022

Anti-radiation suits for pregnant women use nano-materials of various components to interfere with the wavelength of the electromagnetic signal wave of the mobile phone to achieve the ablation and shielding effect on the electromagnetic wave, thereby cutting off the wifi signal and putting it in a "sleeping" state, making the mobile phone unable to use normally. Just like a wifi jammer, you can also use some metal boxes to put your mobile phone inside, which will also affect the signal of the mobile phone. The thicker the metal, the worse the mobile phone signal. This is because the signal sent by the base station will be directly blocked after penetrating the metal.
