Note: In wireless communication, the phrase (phz) (petahertz ) refers to the frequency of transmission of radio signals in cycles per second (number of oscillations per second).

^{Computer networks operate at different transmission frequencies, depending on the technology they use. Wireless networks also  operate in the range of band frequencies instead of an exact frequency. Networks that use high-frequency wireless radio communications do not necessarily offer higher speeds than low-frequency wireless networks.}

^{The significance of the petahertz frequency from the opposite wavelengths is as follows: The frequency of 30 PHz to 3XHz is called soft X-ray (SX). The frequency of 3PH to 33PHz is called far ultraviolet (EUV). A frequency of 750 terahertz to 3 petrohertz is called near ultraviolet (NUV) radiation. Frequencies that consist of the PetaHz band and are a subset of this frequency (PHZ) are mostly used by the military; Medicine becomes:} 

^{SX; EUV; NUV} 

^{Sx Wavelength: Soft X-ray or SX wavelength   is a type of radiation called electromagnetic waves. Imaging with this ray creates images from inside your body. These images show parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. X-rays are an energetic state of light that cannot be seen by the human eye. Light has different forms such as; Radio waves are microwaves, infrared waves, visible light, ultraviolet waves, X-rays and gamma rays.}

 ^{EUV wavelength:}

 ^{EUV ultraviolet light has a short wavelength and high energy and is invisible to the human eye and is located in the electromagnetic spectrum between X-rays and visible light. The presence of this radiation in sunlight causes sunburn on the skin of the body. This ray has a wavelength between 400 and 100 nanometers. Ultraviolet rays of sunlight are divided into 3 categories: UVA, UVB and UVC. Which is divided by different wavelengths.}

NUV wavelength: 

^{NUV ultraviolet light can be used to disinfect water, food, medical equipment and industrial supplies, etc. This radiation can be divided into the following subgroups according to the degree of penetration:}

^{NUV - near ultraviolet with a wavelength of 200-400 nm (apparently low risk to environmental health)}

Conclusion :

In wireless communication (pz) (petahertz ) refers to the frequency of transmission of radio signals in cycles per second (number of oscillations per second).
