EAP testing without AP?

Hi all, I'm new to EAP and want to setup freeradius with EAP-TTLS support. After some struggling with 802.1x doc and terms, the radiusd is up. However, as my testing AP is not ready now, I've no way to test my setup. I wonder if it's possible to test the authentication server<->authenticator<->supplicant setup under an 'simulated' environment without AP since I only want to test the authentication setting. Would anyone please help? Thanks in advance. /ST Wong
