What is mmWave?

Millimeter wave (mmWave) is a high-frequency band of the electromagnetic spectrum. MMwave frequencies are typically between 30 GHz and 300 GHz. These frequencies are much higher than those used in cellular networks and Wi-Fi, which operate in the low- to mid-GHz range.

MMwave signals have very short wavelengths, which means they can carry a lot of data. But because they are so high-frequency, they are also very susceptible to interference and obstacles. This makes it difficult to use mmWave for long-range communications.

MMwave is being used in some 5G cellular networks, as well as in short-range applications such as WiFi 6.
