Can 5G penetrate through 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.

However, it is expected that 5G signals may suffer interference. They can be easily blocked or diffused by physical object (buildings or atmospheric and environmental events) and will have a smaller footprint compared to other waves (2, 3 and 4G)[3].

5 GHz networks do not penetrate solid objects such as walls nearly as well as do 2.4 GHz signals . This can limit an access points reach inside buildings like homes and offices where many walls may come between a wireless antenna and the user.
