Eric L: Significant Qualcomm news. Views of Samsung. (Suggest those uninterested in Qualcomm and its future, skip.) SEOUL, South Korea — Samsung expects to deliver third-generation (3G) cellular systems next year that support services with data rates up to 15 Mbits/second, exceeding the maximum 2-Mbit/s rate typical of 3G systems that follow the International Mobile Telecommunications (IMT) standard for services using the 5-MHz spectrum band. Samsung's work is based on the IMT-2000 standard being hammered out by the Third Generation Partnership Project 2 (3GPP2). The systems would be based on an extension to the 1X EV technology that the 3G project is now developing. That technology ensures data service up to 5.2 Mbits/s using a 1.25-MHz band, the same chunk of bandwidth used by today's CDMA-based cellular systems. The 3GPP2 group expects to offer a 3X version of the technology that delivers 5.2 Mbits/s over a 5-MHz swath of spectrum, Samsung said. The company claims that the use of synchronous technology will provide more than a sevenfold efficiency gain compared with the asynchronous method used in 3G systems that deliver data rates of 2 Mbits/s. The synchronous approach will also allow more-flexible systems that can support standards like those coming for both the 1X EV and cdma2000 technologies, Samsung said. This approach will make it easier for service providers to upgrade from one service to the next or to increase the number of subscribers without replacing underlying hardware. OEMs here have almost completed cellular systems based on the cdma2000 1X (IS-95C) specification, which can provide a basic platform for synchronous IMT-2000 services. These systems are expected to be commercially available in October. Major IT companies in South Korea, including SK Telecom and LG Telecom, are preparing to support cdma2000 1X (IS-95C) services, which are expected to go live here in the second half of this year. Korea's equipment manufacturers hope to beat competing systems from suppliers outside Korea by as much as three months. The 1X EV systems, meanwhile, are slated to be available in the second half of 2001, when that standard is expected to come to a final vote. For its part, LG Telecom started its development of wideband CDMA systems in 1999. However, the work is not expected to be finished until late 2002 at the earliest.

QCOM Press Releases and iMSM Eric L. and Cha2 I hadn't intended to make Tekboy the go-between with my drivel on the Qualcomm chipset issue. I have much less idea than you what the difference is (if much) between MSM and iMSM. I have no tech background. When I bought a Nokia cell phone last December, I thought TDMA was the AT&T brand name for CDMA.(!) My lengthy education has not equipped me with any useful knowledge or job skills. The Qualcomm press releases came up in the course of doing more DD and preparing a glossary of terms to avoid the unfortunate TDMA/CDMA kind of thing again. The press releases seemed a good source to understand the alphabet soup surrounding 2G or 3G, or what is maybe a bridge between the two. I had no business being there, and I wasn't getting anything different out of the MSM or the iMSM releases. I thought it was because I'm stupid. I can see now that it wasn't just that. But, what all the reading has done is make me finally maybe actually understand what Mike Buckley and others have been saying for some time in posts like Message 13987398 Cheers Mike
