IEEE 802.11 (Wi-Fi) protocol

IEEE 802.11, commonly known as Wi-Fi, is a set of standards that enable wireless communication between devices like laptops, smartphones, and routers. It allows devices to connect to the internet and each other without cables by transmitting data over radio waves within a local area. The protocol manages how devices share the wireless medium, coordinate data transfers, and ensure reliable communication. Different versions of Wi-Fi offer improvements in speed, range, and security, making wireless connectivity efficient and secure for everyday use in homes, offices, and public spaces.
