Rajala, I know you think WLL is a dog. However, do the following: go to the following link cdg.org on the left side of the page click on the WLL button. At that page scroll down to the table "Global Deployments" and check it out. Now, consider that this is just the tally for CDMA. Think about the idea that many of the major GSM manufacturers are also working on WLL. Many millions of dollars are being invested in this technology. Consider that none of the information I have guided you to is opinion or conjecture but simply fact. No Biased pro WLL reports from MBA's trying to justify the money. But, if you want to read a little more...go to the bottom of this page and follow the link "Economics of Wireless Local Loop". Check out the information. If you disagree with their assertions there is an email address and they will be happy to talk it over with you. Best Regards Walt

There may be some discrepencies in Rajala's dogma: >I have always wondered, engineer, whether you wear one of >those funny engineer hats when you write your postings. I >think we should be told. Hmm, this must pass for wit in your company. Civil discourse it surely aint. In post 16808 you write: "I believe in good concepts & long term, debate and critique" No sign of it in the passage above. Still. I need to understand your position on WLL CDMA. In post 16857 you write: "First of all, let's remember where the 3 x capacity advantage for WLL is supposed to come from: the reduced non-traffic signalling, such as power control etc. which is estimated to take 2/3 of CDMA1 capacity (!) when it takes only between 1/8 and 1/16 of GSM capacity. We are talking about the same basic functions, nicht wahr? Do we all accept that CDMA1 eats bandwidth like a lewinsky with 10 x more inefficient signalling than GSM?" To an unsuspecting reader this would give the distinct impression that you think CDMA wastes 2/3 bandwidth in signaling. Of course the reader would be entirely wrong, since in post 16864 you write: "There has been plenty of counter argument about how "inexpensive" (CDMA) based WLL is, as compared to CDMA1, which I did not buy. I did not believe that "signalling" (terminology appears to vary , I mean all supportive signalling that makes the call possible but is not the content of the call) in CDMA1 is 2/3 of the total traffic" Okay so you think CDMA does NOT take 2/3 of the total capacity for signaling. Fine. You have changed your mind. It happens. I think I understand. But wait, in post 17012 you write, in response to Engineer: "OK so you say there is no signalling problem. Then you say you save 2/3 of the capcity by not having more accurate power control and by not having to deal with handoffs. Well, power control and handoff are signalling." No. Power control is signaling after all, and CDMA is wasteful. Okay now I am somewhat confused. Or is it you changing your position again? Which is it? Is CDMA wasteful or not? No wonder Engineer and I (and may be others?) are having difficulty with your posts. But what of your views on WLL? "It is a dog". "It is lousy". "Bad idea". "WLL concept is dog" Hmm, I think I am beginning to understand your idea of "longterm debate & critique": unsubstantiated dogma. Regards.

"CDMA Wireless Business Opportunities" Report Predicts Rapid Growth of CDMA A 208-page report from Datacomm Research Company concludes that cdmaOne is poised for rapid growth in North America, Asia, and Latin America. The report forecasts cdmaOne subscribers will grow from 8 million at the end of 1997 to over 165 million by 2003. The report presents regional (North America, Europe, Asia, Latin America, and Rest of the World) and worldwide forecasts for CDMA and GSM. Sections on Technology, Applications, Markets, Competition, and Future Considerations provide detailed analysis based on over three years of research. Sections devoted to infrastructure, subscriber devices, and network operators profile over 50 vendors, including AirTouch Communications, Ameritech Cellular, Bell Atlantic Nynex Mobile, Bell Mobility, Clearnet, DDI Corp., Globalstar, Hughes Network Systems, Hutchison (HK), Lucent, Motorola, NextWave Telecom, Nortel, Oki Telecom, Philips Consumer Communications, PrimeCo, Qualcomm, Samsung, Shinsegi, Siemens, SK Telecom, Sony and Sprint PCS. Purchasers of the report will receive a free supplement, "Quest For A Third-Generation Standard," to be released at the end of May, 1998. Following are brief excerpts from "CDMA Wireless Business Opportunities." Executive Summary: "in order to catch up with GSM, CDMA players must concentrate their efforts in three key areas: 1). converting analog subscribers to digital, 2). growing wireless data, and 3). interoperating with GSM. . . . . . Growing the wireless data market will benefit the CDMA industry because it expands the universe of potential users to not only people but things. Viewed from this perspective, the markets of the U.S. and Japan are vastly larger than those of China and India. Every automobile, gas pump, ATM machine, vending machine, and security system is a potential CDMA user." (Sounds like a job for CDMA WLL, eh Raj?!! -t ) Technology Section " A wireless telephone network is similar to an electric power plant. a power plant must be designed to handle peak demand. Once the power plant is built it will operate most efficiently at or just below peak load. Under lighter loads, the power plant operates less efficiently and, therefore, the profit margin is smaller. It is in the interest of the power company to try to smooth out demand over both diurnal and seasonal cycles. This might be done, for example, by encouraging customers to run heavy machinery between 12 and 6 AM. . . While mobile telephone are less susceptible to major seasonal fluctuations in demand, they are more susceptible to diurnal fluctuations."
