What is millimeter wave in 5G?

Millimeter waves — often referred to as mmWaves or high-band 5G — are frequencies starting at 24 GHz and beyond . As radio waves increase in frequency, each wave narrows in length. Because of its high frequencies, mmWave has a limited range of only 300 to 500 feet and struggles to penetrate buildings.10 Eyl 2021

Why is millimeter wave faster?

Comparatively, the maximum carrier frequency of the 4G-LTE band, 2 GHz, provides an available spectrum bandwidth of only 100 MHz. Therefore, using millimeter wave frequencies can easily increase the spectrum bandwidth by a factor of 10 , allowing for a massive increase in transmission speeds.

What is the millimeter wave radar?

Millimeter wave (mmWave) is a special class of radar technology that uses short- wavelength electromagnetic waves . Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects.
