How is a 5 GHz network signal weaker than a 2.4 GHz network signal when penetrating walls?

Dear user, we are sorry for your inconvenience. A 2.4 GHz network has better wall penetration performance than a 5 GHz network does. This is determined by physical characteristics of the electromagnetic wave: the longer the wavelength and the smaller the attenuation, the easier it is to penetrate obstacles. 5 GHz signals have a high frequency and a short wavelength and 2.4 GHz signals have a low frequency and a long wavelength. Therefore, 5 GHz signals have larger attenuation through obstacles and poorer wall penetration capabilities than 2.4 GHz signals. Therefore, most IoT devices do not support 5GHz networks.
