WiFi Technology

WiFi Technology is a wireless communication protocol, based on the IEEE 802.11 family of standards, that enables electronic devices to join a computer network and access the internet without physical cables. It functions by using radio waves to transmit data between devices and a central wireless router, thereby creating a Wireless Local Area Network (WLAN). This ubiquitous technology provides the high-speed, convenient connectivity essential for a vast range of modern computing applications, from personal laptops and smartphones to the interconnected devices within the Internet of Things (IoT).
