What is the security benefit of using 802.1x wireless protocol?
You can easily configure the access point with this protocol.
There is no need to use router when using this protocol.
Access points don't perform authentication, they rely on authentication server.
Firewall can easily be added in the 802.1x network.
The security benefit is that access point do not need to perform authentication - they rely on authentication server.
IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
IEEE 802.1X defines the encapsulation of the Extensible Authentication Protocol (EAP) over IEEE 802,[1][2] which is known as "EAP over LAN" or EAPOL.[3] EAPOL was originally designed for IEEE 802.3 Ethernet in 802.1X-2001, but was clarified to suit other IEEE 802 LAN technologies such as IEEE 802.11 wireless and Fiber Distributed Data Interface (ISO 9314-2) in 802.1X-2004.[4] The EAPOL protocol was also modified for use with IEEE 802.1AE (“MACsec”) and IEEE 802.1AR (Secure Device Identity, DevID) in 802.1X-2010[5][6] to support service identification and optional point to point encryption over the local LAN segment.
