Caxton,
<< I think the WCDMA problems are known, they don't even have an agreed upon standard yet >>
That gets as old as it is inaccurate.
For all Irwin and Rich's "moving target" baloney, the published 3GPP IMT-2000 standard is 'Release99' with R4 & R5 well defined and in progress (and these include standards for the all IP net).
Nokia, Ericsson, et al commercializing to 'R99'.
Now on the 3GPP2 side we have IS-2000 Release A with Release B which I guess will include TIA/EIA/IS-856 (1xEV-DO) in progress, then 1xEV-DV evolving behind that, and separate discussion of standards for the all IP network, in the works.
Of course CDG still says:
cdma2000 has been divided into 2 phases. The first phase capabilities are defined in a standard known as 1X. Completed in the July 1999, this phase of cdma2000 carriers the TIA standard name of IS-2000 and the ITU standard name of MC-1X. 1X introduces 144 kbps packet data in a mobile environment and speeds beyond this in a fixed environment. Features available with 1X are a two-fold increase in both voice capacity and standby time, advanced packet data services, as well as greatly extended battery life and improved sleep mode technology. All of these capabilities will be available in an existing 1.25 MHz channel.
The second release of 1X is being worked on in the TIA and will support faster data speeds with peak rates up to 614 KBPS.
cdma2000 phase two, known as 3X, incorporates the capabilities of 1X, supports all channel sizes (5 MHz, 10 MHz, etc.), provides circuit and packet data rates up to 2 Mbps, incorporates advanced multimedia capabilities, and includes a framework for advanced 3G voice services and vocoders, including voice over packet and circuit data.
"Moving Targets" aboundeth.
