Can 5GHz go through walls

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.

One of the main drawbacks of millimeter wave-based 5G is that wireless high-band technology does not work well indoors . This is because millimeter wave, or MM wave, signals struggle to penetrate building walls and certain types of glass, thus hobbling indoor 5G performance.

5G’s high frequency can handle more capacity, but the signal can’t penetrate buildings easily . That’s why you may need to install a 5G small cell in your office. Fifth-generation mobile wireless technology, or 5G, is thought to be revolutionary.
