« Back to Glossary Index
Wi-Fi is a wireless networking technology that allows devices such as smartphones, laptops, tablets, and smart home equipment to connect to the internet or local area networks (LAN) using radio waves. Based on the IEEE 802.11 standards, Wi-Fi provides high-speed data transmission over short to medium distances without physical cables. Common frequency bands used are 2.4 GHz and 5 GHz, with newer standards like Wi-Fi 6 and Wi-Fi 6E offering faster speeds, lower latency, and better performance in crowded environments. Wi-Fi is essential for everyday wireless connectivity in homes, businesses, schools, and public spaces.
