the TDMAers will be on a path through GSM or CDMA anyway But how do they get there? They will have to maintain their TDMA service while the new radio access network (RAN) is being built. They will even need the TDMA service for some time after the new RAN is operating .. until subscribers have a chance to get the new phones. Doesn't that, by definition, mean that the new RAN will be an overlay? In order to reduce costs, would not the TDMAer try to keep the existing IS-41 core network (CN)? I sure would think so. But hold on there. While a GSM CN can support a CDMA RAN .. maybe an IS-41 CN cannot support a GSM RAN. Because of the SIM verification, for one thing. So for GSM SIM verification, the TDMA service provider has to replace his core network? Makes me continue to wonder why any TDMAer would have chosen the GSM route. gdichaz, excuse me for butting in and thinking out loud here. I know I am months, maybe a few years, behind most of the people here. Corrections and clarifications most welcome.
