Let's go back to the fundamentals of GSM1X. The technology is all about MSM 6300 phones that can provide dual mode operation between GSM and CDMA1X networks. Since Unicom has both networks, their customers can enjoy the full support of 2G GSM/GPRS and 3G CDMA1X networks. The dual mode GSM/GPRS & CDMA1X MSM6300 handsets are expressly designed to leverage the benefits of GSM1X. <GSM1X terminals utilize a standard GSM SIM and are subject to standard GSM authentication. As a result, operators will be able to offer global roaming and service transparency between CDMA2000 1X and GSM networks without compromising their current infrastructure.> GSM1X press release When you look at the slides from the Tokyo presentation, you can see the GSM1X network infrastructure. On the GSM/GPRS side, GSM/GPRS handsets work on the GSM/GPRS Radio Access which use a GSM/GPRS BTS. GSM/GSM1X MSM 6300 handsets would also be able to work on the GSM/GPRS Radio Access and GSM/GPRS BTS. On the 1X part of the network, the GSM/GSM1X handsets work on GSM1X radio access with a 1X BTS. 1X handsets would also work on the GSM1X radio access and 1X BTS. <The MSM6300 chipset and system software enable handset manufacturers to integrate 3G CDMA2000 1X and 2G GSM/GPRS service into a single handset. The MSM6300 solution supports Release A of the CDMA2000 1X standard, offering data rates of up to 307 kilobits per second (kbps) on both the forward and reverse links, along with simultaneous voice and data services. The GSM and GPRS solution is Phase 2+ compliant, supporting class B, multi-slot class 8 data services with data rates of up to 40 kbps on the forward link. User identity is supported in both the R-UIM and SIM standards, with an integrated R-UIM/SIM controller.> MSM6300 product description I dont' know how much more obvious it can get. Qualcomm cleared up a lot of confusion for anyone wondering about Unicom's dual mode GSM1X potential. Unicom is free to upgrade all the 2G GSM/GPRS subscribers to 3G GSM1X(EV) as the MSM6300 handsets become available.
