Thanks for the additional info on GSM1x. As always, I have a few questions. Now .. GSM1x is intended to serve (1) GSM phones, (2) GSM phones using the 1x air-interface, and (3) 1x phones using the 1x air-interface. What do you mean for (2) "GSM phones using the 1x air-interface"? If a phone is dual mode CDMA/GSM or GSM/CDMA don't each of the modes use software appropriate for that mode? If you use such a phone on a GSM network, is it not indistinguishable from any other GSM phone? If you use it on a CDMA network is it not indistinguishable from any other CDMA phone? re (2): For serving a phone with a 1x air-interface and a GSM software protocol stack, the 1x RAN could be connected directly to the GSM CN .. theoretically, at least. (I recall reading that the 1x RAN specification supported both the IS-41 MAP (for CDMA) and the GSM MAP. If pressed, I will try to find a link.) Would there really be a phone with a 1x air-interface and a GSM software protocol stack? How about an alternate dual mode phone, perhaps from a different vendor, with a GSM air-interface and a CDMA software protocol stack? How would such phones be different from each other, and how would a user know which they were buying? I see nothing wrong with the "GSM1x user" term. That's a person with a GSM1x phone, to my mind. Per above "discussion", it should be clear that a phone with a GSM protocol stack and a 1x air-interface can be properly called a GSM1x phone. My opposition to the term GSM1x user, which applies/applied to GSM1x phone as well, is that I thought (am still not fully convinced, see above) that a dual mode CDMA/GSM phone was really two phones in one, not a pure phone when using one air interface, and a bastardized version when using the other. If this is true, then I guess it means that some dual mode phones will legitimately be called GSM1x and others with the same two modes, GSM & CDMA1x will not. Color me still confused.
