[DANORM]

Hello Guys

I have question about CDMA2000 1X optimization:

Is there any new features about CDMA optimization besides standard Drive Test analyzing and using standard OMC tools?

I mean the newest features of CDMA optimization for example as i know there is Virtual Drive Test (But i have no idea what is this).

If you have some documents about new features please send me in PM.
