This improvement will not only affect 5GHz networks, which the industry has largely shifted to, and which provide faster data on shorter distances; it will also make 2.4GHz networks faster, which are typically slower but better at penetrating solid objects like walls.

Can 5g WiFi penetrate 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. … However, 5GHz networks are not necessarily faster than 2.4GHz.

Does WiFi travel better up or down?
