IEEE 802.11

IEEE 802.11 is the family of IEEE standards that specify the medium access control and physical layer protocols for wireless local area networking, first published in 1997. Its amendments underlie the Wi-Fi brand, administered by the Wi-Fi Alliance, and provide the basis for the world's most widely used wireless computer networking technology, letting laptops, phones and other devices reach a network and the internet without a physical cable. Successive amendments, including 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax, raised the standard's speed and range over more than two decades.
