About Megahertz (MHz)
A frequency unit equal to exactly 1,000,000 Hz = 10⁶ Hz. MHz is the dominant band for commercial broadcasting, two-way-radio, and consumer wireless: FM (Frequency Modulation) commercial radio band 88-108 MHz per FCC Part 73; VHF television broadcast band 54-216 MHz (now repacked post-incentive auction); UHF TV 470-608 MHz; amateur (ham) radio 2 m band 144-148 MHz + 70 cm band 420-450 MHz per FCC Part 97; LMR (Land Mobile Radio) for public-safety + first-responders 150-174 MHz VHF and 450-470 MHz UHF per APCO P25 + DMR / NXDN / TETRA standards; cellular baseband frequencies in the original 800 MHz AMPS band and the later 900-960 MHz / 1700-2100 MHz LTE bands; older microprocessor clock speeds (Intel 8086 ~5 MHz; original Pentium 60-200 MHz; Pentium III 450 MHz - 1 GHz). Spectrum allocation by regulators (FCC, Ofcom, ETSI, ITU-R) is organized primarily in MHz bands in regulatory documents.
About Gigahertz (GHz)
A frequency unit equal to exactly 1,000,000,000 Hz = 10⁹ Hz. GHz is the standard reporting unit for modern semiconductor clock speeds and contemporary wireless: modern CPU clock speeds (Intel Core i9-14900K 6.0 GHz peak turbo; AMD Ryzen 9 7950X3D 5.7 GHz; Apple M3 Pro / M3 Max 4.05 GHz performance cores; the world record overclock is 9.04 GHz on liquid nitrogen with AMD FX-8350); Wi-Fi (IEEE 802.11) bands — 2.4 GHz Wi-Fi 4/5/6, 5 GHz Wi-Fi 5/6/6E, 6 GHz Wi-Fi 6E/7 with up to 320 MHz channel widths; cellular radio — sub-6 GHz 5G in 600 MHz-6 GHz spectrum, 5G mmWave 24-40 GHz per 3GPP Rel-15+ standards (n257/n258/n261); civilian + military radar (X-band 8-12 GHz, Ku-band 12-18 GHz, Ka-band 26-40 GHz for civilian satellite + automotive ADAS radar at 76-81 GHz per ETSI EN 301 091); GPS L1 carrier 1.575 GHz, L2 1.227 GHz, L5 1.176 GHz per IS-GPS-200; microwave ovens 2.45 GHz per ISM band allocation. Semiconductor datasheets, RF network-analyzer traces, and consumer wireless-device spec sheets all use GHz as the default frequency unit.
