About Gigahertz (GHz)
A frequency unit equal to 1,000,000,000 Hz. Gigahertz is the standard unit for modern CPU clock speeds (3–5 GHz), Wi-Fi (2.4, 5, 6 GHz), cellular radio (5G mmWave up to 40 GHz), radar, GPS carrier frequencies (~1.5 GHz), and microwave ovens (2.45 GHz). Semiconductor datasheets, RF network-analyzer traces, and consumer wireless-device spec sheets all use GHz as the default frequency unit.
About Megahertz (MHz)
A frequency unit equal to 1,000,000 Hz. Megahertz is the dominant band for FM radio (88–108 MHz), VHF/UHF TV broadcasts, two-way radio, amateur radio bands, cellular baseband frequencies, and older microprocessor clock speeds (early Pentium: 60–200 MHz). Spectrum allocation by regulators (FCC, Ofcom, ETSI) is organized primarily in MHz bands.
