Ethernet—A popular local area data communications network, which accepts transmission from computers and terminals.
Infrastructure—An integrated wireless and wired LAN is called an infrastructure configuration.
RADIUS—Remote Access Dial-In User Server is an authentication method used in conjunction with EAP for 802.1x authentication and session based keys.
