5G frequency bands

The answer is that the vision for 5G is to not only provide better broadband with higher capacity and higher data rates at much lower cost , but also to address entirely new challenges that span far beyond, to enable new services, empower new types of user experiences, and connect new industries.

The 5G standard uses millimeter waves, which are a lot shorter than the wavelengths 4G uses . The shorter wavelength means 5G can carry a lot of data much faster than 4G, but it also means a much shorter range.

mmWave doesn’t penetrate walls Most building materials, such as cement and brick, attenuate and reflect very high-frequency signals with a big enough loss you’re unlikely to receive a very useful signal moving from inside to outside.18 Ağu 2021

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.

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.

Most cellular “5G frequencies” (higher frequencies) cannot even penetrate a piece of glass. 95% of cellular 5G frequencies are up to 100x worse at penetrating walls, glass, and buildings .
