GHz

Gigahertz (GHz) is a multiple of the base unit hertz (Hz). The German physicist Rudolf Hertz coined the term. Hertz indicates how many oscillations are emitted per second. In computer technology, gigahertz refers to the clock rate of the processor. If, for example, a processor has a 2 GHz processor, then it manages 2 billion cycles per second. In radio technology (for example WLAN) there is the 2.4 GHz or 5 GHz (or 5.8 GHz) frequency. In most cases, 2.4 GHz networks are more resistant to interference than 5 GHz networks, but the 5 GHz band manages much higher transmission rates and distances. Antennas can be used to extend the radio range of the WLAN network.
