Some might call this FUD. I simply call it inaccurate and misleading. When Dr. Jacobs made a similar statement neither UMTS UTRA Direct Spread CDMA (DS) cdma2000 1xMC phase 0 (IS-2000) had been formally approved by the ITU. Since then BOTH have been formally approved.UMTS UTRA Direct Spread (WCDMA) 'Release 99' is an approved ITU IMT-2000 specification. Now that the specification is approved (and frozen) all major infrastructure providers are designing to it, even as 'Release 2000' evolves. Infrastructure will start to deliver next year. Here is the ITU press release on approval of air interfaces:itu.int The press release refers to these 5 approved air interfaces:itu.int Two are CDMA (UTRA DS & MC) and one is TDMA/CDMA (TC). One is TDMA. One is FDMA. Here are the six network-related standards approved for the 3 Core Network Types (Evolved GSM MAP or UMTS - Evolved ANSI-41 - IP based) and the Network to Network Interface (NNI) is included:itu.int Since both UMTS UTRA Direct Spread CDMA (DS) and cdma2000 Multi Carrier MC will evolve in phases we are likely to hear more statements out of Qualcomm like Dr. Jacobs. Qualcomm is in a difficult position relative to UMTS UTRA Direct Spread CDMA (DS). They do not have the same type of control over this committee based standard that they have over cdma2000. 3GGP which evolves the specification has excluded CDG and Qualcomm from participation in it. Although the door seems to be open to them to participate, they have opted not to accept the conditions imposed (full support of DS) and continue to evolve their cdma2000 specification in 3GPP2. This may be sensible at this juncture but it places Qualcomm somewhat at a competitive disadvantage relative to the design of DS ASICs. NTT DoMOCO will implement a nonstandard implementation of WCDMA initially, then backhaul when the standard implementation delivers. This does add some confusion. They however are out of spectrum and need to take this action to grow. << CDMA 2000 is ready for implementation >> Very close. MSM5000 1xMC phase 0 chipsets are being sampled. I'm not sure when commercial deliveries begin. I don't think it will be in QCOM's final fiscal quarter. Base station cards, same thing. Unfortunately, in any country other than the US and Canada, the current cdma2000 specification, 1xMC phase 0, is considered to be a 2.5G specification, not 3G. The UWCC is calling EDGE a 3G implementation, CDG is calling 1x 3G. LU and NT are going along with the charade. The rest of the world is not buying it. The investment community and the investing public aren't buying it. To the contrary. Carriers who are purchasing IMT-2000 spectrum are ordering UMTS. cdma 2000 3xMC when specified will be accepted as a 3G implementation. SK Telecom will probably be the first to implement it as an upgrade to the 1xMC upgrade they plan shortly for their existing network. DDI IDO may implement 1xMC Revision A or they may wait for 3xMC. Right now cdma 2000 3xMC looks to me to be farther away from commercial delivery than UMTS UTRA Direct Spread CDMA (DS). 2.5G 1xMC phase 0 will achieve higher data rates, quicker better, and faster, than GPRS. Unfortunately by 2004 GPRS will become the dominant air-interface in mobile wireless telephony. By about 2007 or 2008 UMTS UTRA Direct Spread CDMA (DS) may become the dominant air-interface. - Eric -
