5G protocols

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 .

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

Though the high frequencies of 5G require a direct line-of-sight , “fixed wireless” will allow for cellular coverage within buildings and homes, without the use of cables or lines. Fixed wireless antennas are placed on top of homes and buildings to communicate with nearby small cells or macrocell towers.16 Ağu 2021
