I posted a URL yesterday to an article in EE Times. Since I know what a pain it is to look up URLs I will post excerpts:

... (UMTS) the follow on to the second generation Global System for Mobile communications (GSM) digital standard. This proposal-- sponsored by ... Ericcson and Nokia-- has been deliberately made compatible with a Japanese wideband-CDMA scheme developed by... NTT-Docomo. Its adoption is thus a prerequisite to emergence of a world standard.

... This hybrid approach (my note: they are talking about the proposal from MOT, Alcatel, et al) might provide a lower-cost rollout for GSM network operators, since the GSM standard is based on a TDMA air interface.

... Though origionally conceiving of IMT2000 as a unified global standard the ITU has now accepted that it should embrace a family of standards with the caveat that each should seek to enable the concept of hand-off and global roaming. ETSI's choice of air interface enshrined within the UMTS spec, will be put forward to ITU in June.

...The main effort in the United States focuses on maintaining backward compatability with the second-generation IS-95 CDMA networks currently being rolled out across North America. This requires a form of wideband-CDMA air interface incompatable with the Euro-Japanese proposal.
--------------------------------------------------------------------

I have cut lots out of the origional article, but I think that you get the idea. One interesting thing to note is the authors mistranslation of GSM. We, on this thread, know that GSM stands for Groupe Speciale Mobile after the comittee that created it. This leads me to question how much research they really did.

Some of the stuff in the article is fairly revealing though. The author mentions that the air interface needed for advanced IS-95 is inherantly incompatible with the new european proposals. Yet they also say that the CDMA proposal was purposely made compatable with NTT DoCoMo's proposal for a 3G system. I thought that the prez of NTT and Irwin Jacobs got together and agreed that their two systems would be compatable. Something happened to that?
