Aaron,

a WPA or WPA2 compliant device, by definition, supports two alternative 
modes for authentication:

    a) pre-shared key authentication mode which is secure but not
    scalable because it requires the sysadmin to install the pre-shared
    key in each device (Access Point or client/supplicant) that is to be
    secured. The major benefit of this mode of operation is that the
    wireless medium can be secured without the need for an
    authentication server such as Microsoft IAS or some other RADIUS
    type of server that also supports necessary 802.11i protocol components.

    b) 802.1X authentication mode which is both secure AND scalable
    because it makes use of an authentication server/service such as
    that provided by RADIUS with the necessary 802.11i protocol support.
