Why is 5G called mmWave?

These high-frequency bands are often referred to as “mmWave” due to the short wavelengths that can be measured in millimeters . Although the mmWave bands extend all the way up 300 GHz, it is the bands from 24 GHz up to 100 GHz that are expected to be used for 5G.6 May 2021

Why is 5G mmWave blocked by walls?

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.
