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.
Detailed explanation-2: -In short, the transmission of data wirelessly is made possible by the manipulation of radio waves. These waves are generated naturally by generating pulses of electricity. These radio waves can then be modified by their amplitude or frequency in order to transmit sound or data.
Detailed explanation-3: -Radio waves are like light waves-they are electromagnetic energy traveling at the speed of light. Frequency equals the number of waves that pass a specific point in one second. The measure of frequency is hertz. There are three license-free radio frequency bands used in radio frequency wireless networking.
Detailed explanation-4: -Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.
Detailed explanation-5: -Various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. Most radio waves pass freely through Earth’s atmosphere.
