NetWeaver Mobile DOE 7.3 stand alone server?

Is there any "stand-alone" NetWeaver Mobile 7.3 like the previous versions (NetWeaver Mobile 7.1 or 7.1.1) or we need to install the consolidated NetWeaver 7.3 (portal/CE/PI/Mobile) in order to just use NetWeaver Mobile 7.3 server?

Thnaks for any answer.
