Overview[]
"Radio frequencies are grouped into bands and are measured in units of Hertz, or cycles per second. The term kilohertz (kHz) refers to thousands of Hertz, megahertz (MHz) refers to millions of Hertz and gigahertz (GHz) to billions of Hertz. The Hertz unit of measurement refers to both the quantity of spectrum (such as 75 MHz of spectrum) and the frequency bands (such as the 5.850 – 5.925 GHz band).[1]
