Ben,
<< Simply stated, being ANSI-41 and GSM Map compliant means that CDMA and GSM based systems will communicate without smart cards or dual mode chipsets. >>
Sorry Ben. That is ABSOLUTELY WRONG! Qualcomm lost that battle a long time ago.
A "physical" & "removable" SIM (USIM) or as the CDG world calls it, a R-UIM, is a mandated ITU IMT-2000 component.
OHG made absolutely sure the good Doctor FINALLY got this message and the 6 3GPP SDO's drove it home.
In order to get into compliance, early this year, CDG fast tracked an R-UIM specification through TIA. CDMA became the LAST major technology in the world to approve the use of a SIM/USIM for the requisite capability to authenticate to the 350+ GSM networks on air.
Without a USIM (R-UIM), no cdma2000 chipset is IMT-2000 compliant, and no CDMA terminal can authenticate to a GSM, VSAT, GPRS, TDMA-EDGE, GSM-EDGE (if that ever exists), or UMTS network.
For this reason (and several others) The Qualcomm MSM5000 chipset (built to Qualcomm's draft specification of 07/99), is therefore not IMT-2000 compliant. The (2G)MSM3300 is. The (2.5G) MSM 5105 will be.
<< This, however, is the future >>
SDR does NOT change this.
