When you get a clue, Keith, let me know. Have you tried reading any of the standards?

One of the outcomes of the outdated release you refer to was that QCOM and ERICY jointly sponsored a proposal to dumb down (my choice of words) the WCDMA chip rate from 4Mcs to 3.8somethingMcs to enable the building of dual-mode (CDMA2000/WCDMA) mobiles (the dumber rate being closer to the CDMA2000 rate). Dual mode, and maybe some changes to the CDMA2000 infrastructure so it can talk to UMTS, is the "single world CDMA standard".

Or are you under the illusion that WCDMA development didn't start until after that agreement?

Keith,

<< What a crock!! ... CDMA2000 is already a standardized technology >>

Speaking of crocks ...

cdma2000 (like UMTS UTRA) is indeed a standardized technology.

The Problem is that what is standardized (IS-2000 Revision A phase 0) does not come close to meeting ITU radio interface requirements for 3G IMT-2000.

As CDG states (http://www.cdg.org/tech/cdma_term.html ):

"cdma2000 is a name identifying the third generation technology that is an evolutionary outgrowth of cdmaOne. .... 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."

Please note that CDG introduced this language to the CDG web site in March of this year. Prior to this 1xMC was referred to as an "interim step" to the introduction of 3G. The first phase capability that they refer to as "completed in July 1999" refers to their original standards submission which included only a CDMA MC component and not an HDR component. In actuality considerable changes were made to the IS-2000 standard that was approved by the ITU in April 2000 and this interim standard does NOT complete Phase 1 of 1X, and it does NOT include an HDR component.

Left incomplete is (was) Phase One Revision B:

"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"

The CDG website then describes cdma 2000 Phase 2 which has yet to have even begun standardization:

"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."

There has of course been some considerable "gear shifting" on the part of Qualcomm, CDG, and 3GPP2 which was announced in June.

As part of Revision B, HDR is being incorporated as 1x-EV. There will be two phases of incorporation of HDR. First standardization needs to complete for 1X-EV Data Only (DO) then (optimistically) 7 months later 1X-EV Data and Voice (DO) needs to complete. It appears that Phase Two (3xMC).

You would be well served to closely follow the posts of our "Moderated Qualcomm" threadmate, Ben Garrett, who is following this closely. This post is most important:

Message 14488506

It appears that 3GPP2 has missed the October target for completion of 1xEV-DO which could have yielded a December publication date of the standard. This jeopardizes the May 2001 target for 1xEV-DV, which probably would have triggered Phase Two (3xMC) cdma2000 standardization if it is not going to be abandoned (which I assume it will not be).

It is possible that 'Release 2000' of UMTS UTRA will be completed before the next Revision of cdma2000 Phase One. The focus of 'Release 2000' is of course, primarily on the IP network, and "services" rather than the radio interface.

Your statement that "CDMA2000 is already a standardized technology" would be better stated "The first release of the initial phase of cdma2000 has been standardized".
