As wireless communication became advanced, it’s not just older, slower devices that are left behind, but also the requirement of effective EMF shielding has grown, which provide effective protection to humans & also protects sensitive electronic equipment used in hospitals against higher frequencies that are used to send data (Wireless Telecommunication).

Health effect of EMF clearly mentioned in the below link:

Hyper Stealth Technology offers highly efficient shielding paint for protection against high-frequency electromagnetic fields, low frequency electric fields and RF/Microwave radiation.

The paint offers constant attenuation, without preferred direction of polarization, for frequencies of up to 40 GHz. This means, perfect protection against any higher Gigahertz range is guaranteed in the future which may arise due to developments in telecommunications industry.
