mmWave stands for Millimeter wave, a telecom abbreviation.

Radio frequencies roughly between 24 and 100 GHz, used by 5G for multi-gigabit speeds over short distances. Signals are easily blocked by walls, foliage and even hands, so coverage is limited to dense urban spots, stadiums and fixed wireless links.

Example: The stadium has mmWave 5G, so the speed test topped 2 Gbit/s near the field.

Usage notes

Strictly, millimeter waves span 30 to 300 GHz, with wavelengths of 1 to 10 mm, but the industry applies the term to all 5G bands above 24 GHz. Verizon built its early 5G service on mmWave before shifting focus to mid-band spectrum. Phones need special antenna modules to use it, and many models sold outside the United States omit mmWave support.
