chapq, << Perry LaForge ... I prefer his statement to Conway's >> CDG was an early invitee to GRF. They dragged their heels. CDG has never shared the global roaming vision of GSMA. << along with the MSM 5200 to be sampled later this year lead me to believe there will be full enough interoperability to allow global roaming among 2G and 3G GSM/CDMA systems >> Nope. It will apply to Japan where there are no 2G or 2.5G GSM networks and could apply to Korea, although Korea will be looking for a multi-mode chip to support cdma2000 as well as W-CDMA. The MSM5200 Mobile Station Modem chipset and system software is designed to address the Frequency Division Duplex Direct Sequence Wideband CDMA (FDD DS-WCDMA) mode of the IMT-2000 standard ... supporting 384 kbps on both the uplink and the downlink. That's all she wrote, so far as I can tell. << There should have been no need for compatibility with a 2.5G GSM system immediately preceding the inevitable 3G CDMA system. >> There absolutely has to be. Look at how the majority of UMTS systems will be built out (by existing GSM carriers). The GSM network will be GSM - GPRS - W-CDMA. cdma2000 is nicely backward compatible with IS-95A and IS-95B. UMTS has its own migration path for the majority of wireless operators in the world. that is the way the standard was developed in parallel with GSM Phase 2+ and GPRS. << The GPRS rollout is probably a hindrance to the goal of a global 3G system >> From the viewpoint of a QUALCOMM shareholder (of which I be one) perhaps it is. But, it is a practical, cost effective evolution, allowing network reuse. To bad GPRS wasn't 1xRTT but .... - Eric -
