Ericsson is indeed helping us out. They've defined harmonization and explained that it has nothing to do with backwards compatibility: “ For several years of 3G standardization, extensive efforts have been made to ensure harmonization. In this context, harmonization means the adoption of the optimal components of each proposed technology on their technical merits as long as it is in line with the fundamental requirements on market-driven standardization. Harmonization is not the same as backward compatibility, where one specific technology or group of operators and users would potentially benefit more than others.” In other words we'll take what we want from your proposals for our standard and we're not particularly interested in converging our standard with your standard or whether you're interested in convergence. “Compatibility and ease of integration with 2G technologies over future mobile terminals has always been an important issue in 3G. This is, however, not the same as seeking unrestricted and complete convergence in todays multi-standard environment and worldwide mobile marketplace with a single solution for which all operators must make provisions.” “WCDMA is a completely new technology best suited to meet 3rd-generation requirements. The principle of the free choice is why worldwide support has been building for WCDMA as a powerful technology for new spectrum – a completely new concept not related to, or limited by, any 2nd-generation wireless technology.” In other words: WCDMA is a completely new technology with the best concepts from the various proposals “in harmony “ which , by coincidence, is most easily upgraded to from GSM They still seem to be talking out of both sides of their mouths but maybe I just don't get it. They're saying they want multiple standards: "This points directly to a de facto multi-standard environment with standards and recommendations that include different technological elements. This is a consequence of the need to satisfy different market and regulatory scenarios.” And they claim CDMA2000 and WCDMA would be “harmonized” by their proposal:  The Ericsson proposal for harmonized third-generation mobile communications offers equal opportunity to all operators and users worldwide. The Ericsson proposal would allow operators to migrate to third-generation (3G) mobile communications independent of their current technologies. The solution from Ericsson would harmonize WCDMA and cdma2000 systems making it possible to produce low-cost dual-mode mobile phones and terminals to serve users across the two system standards. Ericsson's initiative is based on a reduction of the so-called chiprate of WCDMA from the present 4,096 Mcps to 3,84 Mcps. The solution bridges WCDMA and cdma2000 technologies and lays the foundation for harmonized world standards, offers equal access to global terminal market volumes and also facilitates global roaming. Standardization is dealing with two sometimes conflicting rationales.. On the one hand it's desirable to create the best of all possible systems for the carrier who intends to build an entirely new 3G network from scratch. At the same time many carriers have already made huge investments and to whatever extent possible these investments should not be wasted. Adding to the complexity is the fact that there are no 3g systems ready for sale, so that whomever wishes to get started has to do so with a 2g network, which as has been oft repeated is what a lot of the fighting is about. Seems to me that GSM carriers have a legitimate interest in protecting their equipment investment, as do those who built CDMAone. Ericsson is essentially arguing that “we have the largest installed base therefore our migratory path should define the “standard”. They do in fact have the largest installed base. Without it they'd have no leg to stand on whatsoever. I'm sure you all noticed how WCDMA was placed nicely square in the middle of the other two lower , “regional” standards. Qualcomms' White Paper already nixed every thing in this Ericsson proposal so there doesn't seem to be any real public movement at all, unless the chiprate move is some sort of signal that they're willing to go ALL The Way to 3.6864Mpcs. HOPEFULLY more progress has been made behind the scenes than this. To my knowledge Ericsson has yet to produce an argument which explains why QCOMs' White Paper “Principles” won't work. Just because they haven't done it in public doesn't of course mean that it doesn't exist. Their position might make more sense if they'd make their case… Dave
