Read moreWhat are high frequency waves called?
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 is medium frequency?
Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz) . … The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometer (1000 to 100 m).
Read moreWhat is the difference between Wi-Fi and RF?
Very basically, Wi-Fi is made up of stations that transmit and receive data. Wireless transmissions are made up of radio frequency signals, or RF signals, which travel using a variety of movement behaviors (also called propagation behaviors).1 Mar 2021
Read moreWhat is RF in communication?
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.
