The document is publicly accessible on ETSI site (search by document number). Wording remains the same as previous versions, but sections have changed. Essentially same wording can be found in several IMT-2000 documents that have evolved since the original eight wideband CDMA proposals were submitted to the ITU. The excerpts below are from ETSI TR 101 458 "Universal Mobile Telecommunications System (UMTS); Future Direction of Standards Work on UMTS/IMT-2000", V3.0.0 dated (2000-05) posted on the ETSI site. It is publicly accessible. >> 5.5 What are the radio members of the IMT-2000 family? During 1999 the Operators Harmonization Group (OHG) helped to reach a consensus on how much harmonization and convergence towards a single standard was desirable for IMT-2000. In the case of W-CDMA, it was agreed that there should be a single global standard with three modes of operation which are (a) Direct Spread (DS) (b) Multi-Carrier (MC) (c) TDD ETSI's TD/CDMA system harmonized with the Chinese TD-SCDMA system are the main candidates for (c) and CDMA 2000 will be the main user of (b). The terrestrial members of the IMT-2000 family have been defined by the ITU-R Recommendation [9] as: a) IMT-2000 CDMA Direct Spread b) IMT-2000 CDMA Multi-Carrier c) IMT-2000 CDMA TDD d) IMT-2000 TDMA Single-Carrier e) IMT-2000 FDMA/TDMA The above is the final version of the modified text as approved by the TG 8/1 plenary in Helsinki and then subsequently endorsed by the ITU-R SG8 plenary in Geneva the week afterwards. In terms of relating the ITU groupings above back to things ETSI members are more familiar with: * CDMA Direct Spread (DS) is UTRA's W-CDMA system. * CDMA Multi-Carrier (MC) is the CDMA 2000 system. * CDMA TDD is the harmonized version of UTRA's TD-CDMA and Chinese TD-SCDMA systems being developed in the 3GPP. * TDMA Single-Carrier is the American UWC 136 system based on GSM EDGE technology. * FDMA/TDMA is DECT - this change of title for IMT-2000 Family member e) above, was the final change agreed in the closing plenary at Helsinki. << - Eric -

Not according to itu.int or a number of other ITU, ETSI and 3GPP web pages. Of course, it wouldn't be the first time backers of a losing standard tried to make the winning standard name just a generic name for all the standards, thereby confusing matters and hiding their defeat. You are right although it wasn't always that way. W-CDMA has become the "commonly used" reference to DS-CDMA because of the attempts of the backers of a losing standard to obfuscate the issues. HDR doesn't do voice. Spectrum dedicated to HDR must be taken away from voice. Just FYI. That's the cool part. HDR can handle the data intensive tasks in a separate channel leaving voice to flow freely. Also, channels can be allocated to either voice or data as demand dictates. It's dynamic. Just FYI. I would love to see W-CDMA rolled out as quickly as possible. Unfortunately, even Nokia admits that it will be years rather than months before we see any commercial deployment of DS-CDMA. Of course, this is to Nokia's advantage. They can continue to service the legacy GSM systems and make billions. The longer it takes for GSM networks to migrate to CDMA of any flavor, the more money Nokia makes. There is so much misinformation surrounding CDMA and 3G in the investment world. See the last sentence above for one of the reasons why.
