Wi-Fi, short for Wireless Fidelity, is a technology that enables wireless data communication between devices such as computers, smartphones, tablets, and other network-enabled devices. Here is a simplified explanation of how Wi-Fi works:
Wireless Signals: Wi-Fi operates using radio waves within the electromagnetic spectrum. These radio waves have specific frequencies and are transmitted and received by Wi-Fi-enabled devices.
Wi-Fi Router: A Wi-Fi router serves as a central hub for wireless communication. It connects to a wired internet connection, such as a broadband modem, and converts the internet signal into a wireless radio signal.
Network Configuration: The Wi-Fi router creates a wireless network, also known as a local area network (LAN), within a specified range. The router typically broadcasts its network name (SSID), which users can identify and connect to with their devices.
Device Connection: Wi-Fi-enabled devices such as smartphones or laptops can scan for available Wi-Fi networks and connect to the desired network by selecting the appropriate SSID and providing a security key, if applicable.
Data Transmission: Once connected to the Wi-Fi network, devices can send and receive data wirelessly. The Wi-Fi router acts as a gateway, routing the data packets between the connected devices and the internet.
