Gigabit Wireless Networking with IEEE 802.11ac:Technical Overview and Challenges
The ever-growing proliferation of wireless devices and concurrent deployments of bandwidth intensive applications has been having a significant impact on user experience in high-density wireless areas. IEEE 802.11ac is a recently ratified Wireless Local Area Network (WLAN) standard that promises to improve wireless user experience by delivering gigabit speed to end-user applications. 802.11ac utilizes new technologies such as Channel Bonding, Beamforming, and Multi-User Multiple-Input Multiple-Output (MU-MIMO) to improve wireless performance. This paper reviews recent technological advances made in the field of WLANs and then focuses on the recent IEEE 802.11ac standard.
