Why Millimetre waves are used in 5G?

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 .

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.

Why are 5G mmWave signals blocked?

5G mmWave signals more likely to be blocked by physical barriers such as walls, buildings, and trees because its signals are transmitted at higher frequencies (option D). This can be explained in the following way: Lower frequency bands cover a longer distance but have a slower data rate.
