Nice one Ben. You are right on the track. Although I have to say this, Clark has far more understanding than me in RF stuff:-) In addition to what you said about the asynchronous causing more power consumption, there's another hidden point that usually got ignored, that is WCDMA uses TDM pilot vs. CDM pilot in CDMA2000. IMO, if everything running synchronously with 1.25Mhz, that difference may not that much a big deal because HDR also uses TDM pilot on forward link. But to WCDMA, it is using wider BW and asynch operation makes it extra harder to sync up with pilot at such short timeslot. As a result the pilot acquisition becomes longer therefore more power usage. Anothing is that WCDMA needs more overhead than CDMA2000, both msg count and msg bits, which results in more time and power spent on msg receiving and processing( which will also hurt the capacity). After all the name "idle state" is pretty misleading because a handset is really really busy during "idle state":-)
