The technology that allows multiple devices to connect and communicate wirelessly is known as Wi-Fi. Wi-Fi uses radio waves to facilitate a network connection, enabling devices like smartphones, tablets, laptops, and IoT devices to connect to the internet or each other without physical cables. It operates based on various standards set by the IEEE, primarily the 802.11 series. Wi-Fi is widely utilized in homes, offices, and public spaces, providing convenience and mobility for users.
