Cha2, << But my understanding is that the first step in CDMA 2000 3XRT will follow the introduction of 1XRT in Korea and then Japan beginning this year and then spread in early 2000 >> I have not seen any time tables for commercial deployment of CDMA 2000 3XRT. Have you (in which case I'd greatly appreciate the link). CDG's 3G Pavilion doesn't have anything I can find relative to commercial deployment dates. The article "On the Road to CDMA" I linked to Ruth (repeated below) seems to be as authoritative as anything I've been able to find: telecom99news.itu.int This article states: >> “We don't have many data customers, and there's no real revenue from that type of service. But we will offer it to get a competitive edge,” he says. Kim also feels that the same reasoning is driving Japanese cdmaOne carriers IDO Corp. (Tokyo) and DDI Cellular Group (Osaka) to offer IS-95B. He adds that operators in Korea and Japan cannot risk waiting for another solution-1XRTT-which most consider a more advantageous technology. << I get a little confused (am still a bit confused) about IS-95C (1XRTT) "which is the initial phase of the cdmaOne community's proposal for 3G wireless service". I consider this to be 2.5G despite the wording used in the article. also: >> Among operators planning to test 1XRTT by early 2000 are Korea's LG TeleCom, Sprint PCS (Kansas City, Mo.) and Bell Atlantic Mobile (BAM, Bedminster, N.J.) in the United States, and Australia's Telstra Corp. Ltd. (Sydney), which is slated to commercially launch its 800-MHz cdmaOne network in October 1999. << Are these tests or commercial deployments (I'm not sure)? Are they 2.5G (I think so). >> Of course, the ultimate destination in the cdmaOne data migration is true 3G wireless packet data services at 1 to 2 Mbit/s within 5 MHz of bandwidth. The technological solution for this is termed cdma2000 Phase II, or 3XRTT, because it offers three times cdmaOne's usual 1.25 MHz channel configuration. Some suggest that operators might skip all of cdmaOne's other data iterations in order to wait for 3XRTT availability, particularly if it fits comfortably into a broader family of wideband CDMA solutions. << The last sentence above and in particular the last 3 words really confuse me but I am under the impression that there is a WCDMA project in Korea. I do know that The mobile carriers collaborating with DoCoMomo (which makes me assume WCDMA not FDD MC-CDMA or G3G CDMA MC) include: * South Korea's SK Telecom * Indonesia's PT Telkom * Singapore's SingTel Mobile * Philippines' Smart Communications * the Telephone Organization of Thailand * MEAST Broadcast Network Systems in Malaysia * Hong Kong's SmarTone * Telecom New Zealand. << The exact date for 3XRT and full CDMA 2000 is not clear in Korea and Japan but isn't it likely prior to that of WCDMA even in Japan >> My impression remains that NTT-DoCoMo will be first with the commercial deployment of a 3G system (albeit not standards based). We shall see. If you find better timetables for cdma2000 or can clarify some of my foggy points, please let me know - Eric -
