Detailed explanation-1: -Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz. What does that mean, though? Well, a hertz is just a measurement of frequency.
Detailed explanation-2: -Wi-Fi is a wireless networking technology that connects multiple devices using radio frequency signals to allow for communication and the exchange of information. Wi-Fi uses frequency bands of 2.4 GHz, 5 GHz, and 6 GHz (Wi-Fi 6E).
Detailed explanation-3: -Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the electromagnetic carrier wave as amplitude modulation (AM) or as frequency modulation (FM) or in digital form (pulse modulation).
Detailed explanation-4: -WiFi works off of the same principal as other wireless devices-it uses radio frequencies to send signals between devices. The radio frequencies are completely different say from walky talkies, car radios, cell phones, and weather radios.
