Detailed explanation-1: -And to receive the information found in these waves, your radio receiver needs to be set to receive waves of a certain frequency. For WiFi this frequency happens to be 2.4Ghz and 5Ghz. These waves are very similar to the frequency found in your microwave!
Detailed explanation-2: -Technologies like 802.11 standards (a.k.a. WiFi) use amplitude modulation while other radio technologies continue to use digitally modulated frequency modulation.
Detailed explanation-3: -WiFi actually operates at quite precise frequencies, either 2.4 GHz or 5 GHz, which correspond to wavelengths of either 12 cm or 6 cm. In fact, if you look at your router controls, you’ll probably see a setting to switch between the 2 radio waves.
