High frequency (HF) is the ITU-designated range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz . It is also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres).
Read moreWhat RF frequencies are harmful to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat is radio frequency used for?
Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones , to name a few. Radio frequencies are also applied in carrier current systems including telephony and control circuits.
Read moreWhat is radio frequency and how does it work?
How radio frequency works. Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted . One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.
Read moreWhat is radio frequency signal?
A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication , if one is discussing wireless electronics. Radio waves are a form of electromagnetic radiation with identified radio frequencies that range from 3kHz to 300 GHz.
Read moreWhat is V band RF?
The V-band as defined by IEEE is a frequency range from 40 to 75 GHz . IEEE uses letters to signify a range of frequencies from 1 to 110 GHz. The V-Band is license free in many countries and is most often used for wireless backhaul and point to point/point to multi-point radio links.
Read moreWhat is a band in communication?
In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum , which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf).
