IEEE 801.1x

Adopted as a standard in 2001 IEEE 801.1x protocol provides access control to the port level. He uses the EAP (Extensible Authentication Protocol), which was originally designed to work over PPP (Point-to-Point Protocol) to send messages between the three party authentication in LAN environment - an authentication server (RADIUS-server), the authenticator (wireless access point) and sapplikantom (special software on the client machine). 

This type of encapsulation is known as EAP over LANs or EAPOL. Although the EAP protocol provides more than ten different authentication methods, the most widespread use in wireless networks is the method of PEAP.
