Home > Gigahertz
A gigahertz is a billion hertz or a thousand megahertz, a measure of frequency. Each cycle is one nanosecond. Radio waves sent at gigahertz frequencies usually travel in line of sight. Gigahertz frequencies or microwaves are also used in cellular telephones, microwave ovens, radar and other uses.
Experts in the field of radiocommunications classify categories of spectrum by bands. The names of these bands are idosyncratic, but are used often in radiocommunications.
- L-Band 1-2 GHz (1000 MHz = 1 gigahertz GHz)
- S-Band 2-4 GHz
- C-Band 4-8 GHz
- X-Band 8-12 GHz
- Ku-Band 12-18 GHz
- K-Band 18-27 GHz
- Ka Band 27-40 GHz
- V-Band 40-75 GHz
- W- Band 75-110 GHz
1 CPU frequencies
AMD and Intel released their first desktop processors over 1 GHz in 2000 (though in 1999 a heavily overclocked AMD system broke the Gigahertz barrier).

hertz, kilohertzA kilohertz kHz is a unit of frequency equal to 1,000 hertz (1,000 cycles per second). kHz is most commonly used in reference to radio frequencies and audio signal processing. The name kilocycle is an obsolete name for the same concept. hectohertz << kilo (103Hz), megahertz (106Hz), terahertzA terahertz is 1012 hertz or a thousand gigahertz, a measure of frequency. At one terahertz, each cycle is one picosecond, and the wavelength in free space is roughly 300 μm. Radio waves sent at terahertz frequencies usually travel in line of sight. (1012Hz), petahertzA petahertz is a measure of frequency equal to a quadrillion hertz or a thousand terahertz. In the electromagnetic spectrum, the low end of the petahertz range includes ultraviolet light, visible light, and infrared light, while the upper range includes X (1015Hz).
