mmWave (millimeter wave)

Millimeter wave (mmWave) refers to very high-frequency radio waves in the spectrum between 30 GHz and 300 GHz, with wavelengths between 1 and 10 millimeters. These waves can carry large amounts of data quickly, making them ideal for high-speed wireless communication like 5G networks. However, they have a shorter range and are more easily blocked by obstacles such as walls or rain. Deploying mmWave requires dense infrastructure, including many small antennas, but it enables ultra-fast internet access and supports demanding applications like streaming, virtual reality, and autonomous vehicles.
