The motivation behind the development of wireless technologies is to provide services comparable with the wired networks, easy to install and provides any time ubiquitous access. Wireless networks can be of various forms like WLAN, WMAN, and WPAN. But, here authors have focused on WLANs networks. A wireless network is a type of network that uses wireless data connections for data transmission (short-to-medium distances) as compared to the wired network. Over the past few decades, world has witness significant progress in the area of wireless networking. Wireless networking is gradually replacing the wired networks. This paper surveys about IEEE 802.11 WLANs in detail.
