Wi-Fi uses radio waves to transmit data between devices.
Radio waves are a type of electromagnetic radiation that can travel through the air. They are invisible to the human eye but are used in many technologies, including radio, television, and cell phones.
When you connect to a Wi-Fi network, your device sends and receives data over these radio waves. The data is encoded into a digital signal, which is then modulated onto the radio waves. This modulated signal is then transmitted to the other device.
The Wi-Fi router acts as a central point for the network, broadcasting the radio signal and managing the flow of data between devices.
Wi-Fi uses a specific frequency range for communication, typically in the 2.4 GHz or 5 GHz bands. These frequencies allow for high data transfer speeds and reliable connections.
The strength of the Wi-Fi signal can be affected by various factors, such as distance, obstacles, and interference from other devices.
Wi-Fi is a convenient and widely used technology for connecting devices to the internet and sharing data wirelessly.
