Read moreWhat is the frequency band for RF?
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz .

Read moreWhat frequency range is the high frequency band?
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 moreWhich wave is better for long distance communication?
Sky waves are radio waves reflected by the ionosphere. Therefore, the propagation of these waves is not limited by the curvature of earth. So, these can be used for beyond the horizon communication. Thus, sky waves are used for communication over long (inter-continental) distances.
Read moreWhat is high frequency communication?
High frequency (HF) is an electromagnetic frequency defined by the International Telecommunications Union (ITU) for radar and radio communications . It operates in a range of three to thirty MHz and as the wavelengths spread over ten to one hundred meters, it is also known as decameter wave and designated as band 7.
Read moreWhy do we use high frequency carrier for modulation?
For the transmission of audio signals at distant places, the high frequency carrier waves are used, because these frequency carrier waves travel through space or medium with the speed of light and they are not obstructed by earth’s atmosphere .
