Ben, This would be pre 3G3, with SIM, yes? No, well, yes, sorta. Depends on what you call 3G or 3G3. SIM is a 2G term used by GSM, TDMA-EDGE and ESMR. UIM is an ITU IMT-2000 term that has existed in UMTS specification drafts since early 1997 under 3GIG and on into 3GPP for a 3G SIM. The ITU originally defined a UIM as a physical or logical device. Qualcomm insisted there was no need for a physical UIM. Eventually virtually all the constituents of 3GPP, 3GPP2, OHG, and the Global Roaming Forum, not to mention carriers like China Unicom, SKT, and DDI, insisted on it. So finally a CDMA R-UIM (Removable UIM) was rushed through TIA so that the IS-2000 specification could be finalized, So now GSM, and TDMA-EDGE have a 2G SIM and a 3G UIM (backwards compatabile with 2G SIM). ESMR has a 2G SIM, and CDMA has a R-UIM. Essentially all the bloody same. Esentially it is a 3G3 R-UIM (with backwards compatability to a 2 or 2,5G SIM). As a CDMA user, it is what I have been waiting for. I guarantee you it was what Chris Gent's guys have been waiting for. Great thing about the MSM5105 is that we now have (or will have) a 3G3 (IS-2000) chipset that is compliant with the IS-2000 standard not with the draft standard originally submitted before OHG coined the term 3G3. I'm tacking on some notes here I was just compiling: Note importantant wording in the new MSM5105 Product overview ... QUALCOMM's 3G CDMA Multi-Carrier 1xMC solution, the MSM5105 Mobile Station Modem (MSM) chipset and software is designed to the IS-2000 Standard qualcomm.com Compared to the wording in the current MSM5000 Product overview ... The digital baseband MSM5000 chip enables manufacturers to meet or exceed the specifications of mobile stations for worldwide cdmaOne and cdma2000 systems, including IS-95A, IS-95B and its variants for PCS in North America, Japan, Korea, and South America ... In addition to supporting the requisite 3G R-UIM interface the MSM5105 has the following IS-2000 1xMC RTT features: * Fast 800 Hz Forward Power Control * Quasi-Orthogonal Functions * Supplemental Channel (SCH) support * IS-2000 Forward Quick Paging Channel (F-QPCH) support * Convolutional encoding/decoding for SCH * ITU 144 kbps requirement achieved - Forward dedicated control channel (F-DCCH) - Reverse dedicated control channel (R-DCCH) * Radio Link Protocol (TLP3) * Quick Paging Channel The product overview can be found here: qualcomm.com There is no press release for the MSM5105. All Qualcomm Digital IC Core Products (real and imagined) can be linked here. qualcomm.com Several products shown on Qualcomm's most recent published roadmap (4-28-00) including the MSM5100 have been removed from the Qualcomm website. Others have never been placed on the website. - Eric -
