What is AAA?

AAA is the acronym for Authentication, Authorization, and Accounting and refers to
the idea of managing subscribers by controlling their access to the network, verifying
that they are who they say they are (via login name and password or MAC address)
and accounting for their network usage.

What is RADIUS?

RADIUS stands for Remote Authentication Dial-In User Service. RADIUS is a standard
that has been implemented into several software packages and networking devices.
It allows user information to be sent to a central database running on a RADIUS
Server, where it is verified. RADIUS also provides a mechanism for accounting.

What is WPA?

WPA (Wi-Fi Protected Access) is a subset of the IEEE 802.11i security sepcification
draft. Key difference between WPA and WEP are user authentication and improve
data encryption.

What is WPA-PSK?

WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) can be used if user do not have a
Radius server but still want to benefit from it. Because WPA-PSK only requires a
single password to be entered on wireless AP/gateway and wireless client. As long
as the passwords match, a client will be granted access to the WLAN.
