The IEEE 802.11 group of standards defines the technologies for wireless LANs. The IEEE 802.11b and 802.11g standards define a single range of radio frequencies from 2.412GHz to 2.472GHz that are to be used for wireless network transmissions. LAN stands for Local Area Network. A LAN is a network of computers and other electronic devices that covers a small area such as a room, office, or building. This wifi security describes security mechanisms, WEP protocol, RC-4 encryption algorithm used in Wireless LAN (WLAN) network. All components that can connect into a wireless medium in a network are referred to as stations (STA). Ethernet is the technology that is commonly used in wired local area networks (LANs). IEEE has defined certain specifications for wireless LAN, called IEEE 802.11 which covers physical and data link layers. 1 Each package contains different versions of the driver for different adapters. It is also called LAWN (Local Area Wireless Network). The 802.3 family is for Ethernet LANs and the 802.11 family is for WLANs.
