Authentication for what? wireless AP?

Meaning what, exactly?

If you mean "check client's user/password, and if it's correct send
access-accept", then that's what radius does, nothing special there.

Generally speaking, radius (ANY radius) doesn't really care what
device acts as NAS. It can be wireless AP, pppoe/pptp server, BRAS,
GGSN, whatever. If they can use the same authentication mechanism
(e.g. PAP, MSCHAPv2, EAP-PEAP-MSCHAPv2) then the radius-side setup is
the same no matter what the NAS is.
