Re: The new Qualcomm/CDG/3GPP2/TIA/IMT-2000 cdma2000 nomenclature

Last evening, you asked:

<< When you mean IS-2000, are you referring to 1x-cdma2000 or 3x-cdma2000 >>

To which I replied:

<< IS-2000 is a newly coined term for cdma2000. I guess it refers to both 1x & 3x, but I am not sure. Tough to keep up with the vocabulary, is it not? >>

After a little further checking it appears that it refers to 1X only.
I have paraphrased the very recently reorganized CDG web site (CDMA Terminology and Definitions page) below.

cdma2000 is a name identifying the third generation technology that is an evolutionary outgrowth of cdmaOne. IMT-CDMA Multi-Carrier (1X/3X) is the ITU name for cdma2000.

* 2 phases of cdma2000

- Phase 1 has a current release and a future release

Phase 1 Release 1 = 1X or IS-2000 (Its TIA standard name) or MC-1X (Its ITU standard name). 1X introduces 144 kbps packet data in a mobile environment and speeds beyond this in a fixed environment. All of these capabilities will be available in an existing 1.25 MHz channel.

Phase 1 Release 2 = 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.

- Phase 2, known as 3X

Phase 2 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.
