Wi-Fi, short for Wireless Fidelity, is a technology that allows electronic devices to connect to a wireless local area network (WLAN), typically using the 2.4 gigahertz (GHz) and 5 GHz radio frequency bands. It enables devices such as smartphones, laptops, tablets, and smart home devices to access the internet and communicate with each other wirelessly within a certain range of a Wi-Fi access point or router.
Wi-Fi works by using radio waves to transmit data between devices and an access point, which is typically connected to a wired network and serves as the hub for wireless communication. When a device connects to a Wi-Fi network, it sends and receives data packets over the air, allowing users to access the internet, stream media, exchange files, and perform various online activities without the need for physical cables.
Wi-Fi technology has evolved over the years, with advancements in speed, range, and security. Modern Wi-Fi standards, such as Wi-Fi 6 (802.11ax), offer faster speeds, better performance in crowded environments, and improved security features compared to older standards. Wi-Fi networks are commonly found in homes, businesses, public spaces, and other environments, providing convenient and flexible internet access for users on the go.
