Cha2,
Re: QCOM needs new PR (not IPR) PR - Secretly (?) announces:
iMSM5500 chipset that combines 3G 1x technology with HDR
<< As usual, it is difficult to track the standards approval process and the chip design and delivery process and distinguish between them. This leads to confusion >>
CDG is really not helping out on this.
Did you ever see this blankety blankety [CENSORED] press release tucked away in a back corner of the CDG web site. If you did why didn't you tell me, instead of letting me wander around in the CDG darkness? <g>
I don't even know how I stumbled across the blankety blankety [CENSORED] thing. I think I did a search on standards or standardization or something (which leads to little):

SAN DIEGO, June 12, 2000 -- QUALCOMM Incorporated, pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced a complete, end-to-end solution in support of an industry-wide movement to standardize, develop and deploy a High Data Rate (HDR) CDMA solution capable of providing up to 2.4 million bits per second (Mbps) peak rate transmission speed for wireless Internet access communications. Trials of HDR using QUALCOMM's iMSM4500(TM) Mobile Station Modem (MSM(TM)) chipset and system software, scheduled to begin in the summer of 2000, will offer customers the chance to further evaluate HDR technology.
"QUALCOMM has worked closely with other members of the CDMA Development Group to facilitate standardization of an HDR solution," said Don Schrock, president of QUALCOMM CDMA Technologies. "The chipsets and system software family that has been developed by QUALCOMM CDMA Technologies combines third-generation (3G) 1x Multi-Carrier (1xMC) technology with HDR to provide infrastructure and handset manufacturers, as well as carriers, a complete end-to-end solution for the development of advanced HDR devices and services that will allow wireless Internet access anytime, anywhere -- at full speed."
HDR offers a spectrally efficient advancement in the data rate over an existing 1.25 MHz channel and provides the lowest cost per bit of any existing technology for wireless high-speed data transmission. The iMSM4500 solution, which supports single-mode HDR, represents the first of several chipsets QUALCOMM CDMA Technologies (QCT) plans to offer that support HDR capabilities. Also incorporated in the iMSM4500 advanced design is dual-receive chain diversity that will enhance a device's HDR throughput. The benefits realized from trials using the iMSM4500 chipset will be incorporated in QUALCOMM's iMSM5500(TM) chipset, which will combine 3G 1x technology with HDR.
The iMSM5500 chipset and system software will provide up to twice the overall capacity of voice users over IS-95A and IS-95B, plus the 2.4 Mbps speed of HDR, fully realizing the convergence of the Internet and wireless technologies and services.
Also part of QCT's end-to-end HDR solution is the CSM5500(TM) Cell Site Modem (CSM(TM)) chipset. The CSM5500 solution, the industry's first HDR CSM standards-based chipset that supports 2.4 Mbps peak rate, represents an economical, power-efficient and highly compatible upgrade from existing Field-Programmable Gate Array (FPGA)-based HDR infrastructure solutions.
Samples of both the iMSM5500 and CSM5500 chipsets and system software are scheduled for mid-2001 with production quantities scheduled for the second half of 2001.
HDR provides a spectrally efficient 2.4 Mbps peak rate in a standard 1.25 MHz channel bandwidth for fixed, portable and mobile applications. Optimized for packet data services, HDR incorporates a flexible architecture based on standard Internet Protocols (IP). HDR is an evolution of CDMA technology with identical radio frequency characteristics as cdmaOne(TM) and 1xMC. HDR supports e-mail, web browsing, mobile e-commerce, telematics and many other applications while offering end users continuous, untethered, always-on access to the Internet and next-generation data services. <<
<< Curious as to when this was actually written for Ericsson and how keyed in the author is to mainstream Ericsson (European) knowledge. Seems like Ericsson is still operating as if the San Diego branch is an Ericsson stepchild whose adoption is not complete. So I assume this represents Ericsson San Diego thinking only. >>
Well old buddy, it's on the main Ericsson web site. Not as hidden as it is on CDG which has no mention of IS-2000-A that I can find.
We do have to keep in mind that Ericsson & NTT DoCoMo (not Nokia) were the companies that jointly presented WCDMA to ETSI & 3GIG for an air interface for UMTS. 5 Proposals were submitted. Theirs was selected. It is now a standard called UMTS UTRA Direct Spread (DS) or IMT-2000 DS. We also have to keep in mind that they are the largest wireless infastructure provider in the world and the toast they butter is called GSM.
But they are our ally, so think nice Ericsson thoughts please.
