What is the role of 802.1x authentication in WLAN?
A. In order to address the shortcomings and Security vulnerabilities in the original methods of authentication that the 802.11 standard defines, the 802.1X authentication framework is included in the draft for 802.11 MAC layer security enhancements. The IEEE 802.11 Task Group i (TGi) is currently developing these enhancements. The 802.1X framework provides the link layer with extensible authentication, normally seen only in the higher layers.
