What’s The Difference Between 802.11n And 802.11ac?
This article explains the difference between the currently popular IEEE wireless local-area network (WLAN) standard 802.11n and the forthcoming 802.11ac, which defines a faster version The 802.11 standard was first available in the late 1990s. It was not an immediate success. When the 11b version arrived in 1999, it facilitated the first widespread implementation of WLAN technology. The 802.11b standard is often considered the first generation, 802.11a is the second generation, 802.11g is the third generation, and 802.11n is the fourth generation. When 802.11ac becomes available this year, it will represent the fifth generation. Today, the most widely implemented form is 802.11n, which is used in access points, routers, laptops, smart phones, tablets, and other mobile devices. Devices using 11n are all backward compatible with older 802.11a/g equipment. The 802.11 standard defines both a physical layer (PHY) and media access control (MAC) layer in the networking scheme.
