<And Ruffian, aren't you particularly ashamed to take such a piece of drivel and extrapolate it into a diatribe characterizing Europeans as mere serfs under the control of their governments? I should think that you owe them all an abject apology. To go from give and take regarding Nokia and Q to attacking Europeans in general is totally uncalled for and destroys all vestiges of your credibility. Who do you think you are - Bobby Knight?> You have the wrong guy..... Booby is going to get fried, new world.

sisuman, << responded so eloquently >> Speaking of eloquence ... << the piece of crap masquerading as analysis ... >> Could you provide a link to an article comparing GPRS and cdmaOne Packet Data that you consider to be not a "piece of crap masquerading as analysis". << Please answer the following questions >> Why certainly (to the best of my meager ability). perhaps you could reciprocate by responding to what I asked in my previous post: "I would be very curious as to your comments on anything in the article that you consider to be inaccurate." Also, I am wondering if you have used the "Mobile Lifestreams" web site before, or subscribed any of their publications or services? I find the site very feature rich and a very good source of information about 2.5G & 3G evolution. Its content is more oriented towards GSM evolution than CDMA even though "Mobile Lifestreams has alliances with both the GSM Association and the CDMA Development Group and therefore has extensive knowledge of both airlinks", to quote their disclaimer. You can access the main site from the GSM Association "Links to Useful Mobile Data Sites" page and clicking on the "Links 2 Mobile" link: gsmworld.com << 1. Who paid for this piece? (It's irrelevant that the authors used to work for Vodafone - some consultants will do or say anything for money) >> I would say that "Mobile Lifestreams Ltd" probably did, but it is unclear who paid them. "Mobile Lifestreams was paid to conduct this research". << 2. Is this a thorough piece of analysis which quantitatively documents all the costs - for operators and consumers - to follow the respective upgrade paths? >> No. It does not purport to be. I think you will have to look pretty hard to find such a piece on the web. It is however an excellent high level article and provides a lot of detail (accurate so far as I can tell) very concisely. I find the tables very interesting and well presented. The same site has an article called "YES 2 GPRS: An Introduction to the General Packet Radio Service" (linked from "Free Papers): mobiledataevolution.com It is still high level but goes into greater detail than the article originally posted here. Please note that the paper (like several others on the "Mobile Lifestreams" can be accessed directly from the GSM Association page under the title: "GPRS - General Packet Radio": gsmworld.com It too, details some of the complexities and limitations of evolving a 2G GSM network to GPRS. Do you consider it also to be a "piece of crap masquerading as analysis"? << 3. Does it also document the costs involved for GSM operators and consumers to switch from GSM to CDMA - and vice-versa? >> No. From a practical point of view, we will not be seeing many, if any, GSM operators from GSM to CDMA - and vice-versa, but we will see many consumers switching where both technologies are offered. This will be based on rate plan, coverage, data rate and services, not technology, but some of this is related to technology available. Nice to live in the Americas, where the choice exists. << 4. Isn't this merely a puff piece aimed at illiterate operators who are becoming wireless operators for the first time? >> I don't think so. I consider it to be a rather informative piece on a rather informative site. As I have noted before I still consider "The Evolution of Cellular Data: On the Road to 3G" by Peter Rysavy of Rysavy Research to be a classic piece on the subject, but Peter is a consultant and as you state "some consultants will do or say anything for money": gsmdata.com Any single article, in an of itself, will not tell a complete story. Any useful links you can provide on the general subject we are discussing and which many who frequent the SI wireless threads might be interested in, would be greatly appreciated. As previously stated, I would also be interested in your comments on anything in the article that you consider to be inaccurate. - Eric -
