Pressures from the market and user organization will lead to interoperation between W-CDMA and cdma2000 networks. However vendors and network carriers will posture and shout for the superiority of their respective technologies. Ideally we should have one standard and one network technology that is superior but that is asking for an ideal business world. We urge user organizations to exert their natural right to force carriers to build one logical 3G network with roaming and interoperability even if this network consists of multiple physical networks.
Following scenarios are most likely:
* Current 2G GSM networks ---->Wideband CDMA (W-CDMA) for 3G
* Current TDMA networks (e.g. AT&T's TDMA network) -----> W-CDMA
* IS-95 (Non-Wideband CDMA) ----> cdma2000
