Qualcomm products mentioned within this press release are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access digital technology, today announced the introduction of the world's first third-generation solution for CDMA digital infrastructure and test equipment products. The CSM5000™ Cell Station Modem (CSM™) represents the first of a family of chipset and system software solutions to support cdma2000™, the third-generation (3G) air interface standard that has been submitted by the U.S. Telecommunications Industry Association (TIA) to the International Telecommunications Union (ITU).In a separate announcement, Qualcomm also introduced the MSM5000™ Mobile Station Modem (MSM™) digital baseband solution for application in CDMA digital consumer devices. Both the MSM5000 and the CSM5000 are compliant with spreading rate 1 of cdma2000 Phase One and will begin field trials in early 2000 with commercial production following the trials."The CSM5000 is our most advanced Cell Site Modem to date and leads the wireless industry in supporting the highest network data rates," said Don Schrock, president of Qualcomm CDMA Technologies. "This major advancement will provide wireless infrastructure companies with the core technology they need to further accelerate the deployment of CDMA networks worldwide."Compliant to cdma2000 Phase One, the CSM5000 solution provides operators up to a doubling of overall capacity of voice users over IS-95A and IS-95B systems. The CSM5000 supports up to 32 simultaneous users on a single chip, a four-fold increase over the previous generation CSM and exceeds the ITU's 144 kilobits per second (kbps) requirement for data rates in full wide area mobility by enabling data rates of 307.2 kbps on both the forward and reverse links."With capacity that provides for up to 32 simultaneous calls on a single chip, the CSM5000 will enable design of new, much smaller and more versatile base station equipment," said Johan Lodenius, vice president of marketing of Qualcomm CDMA Technologies. "Network operators will also benefit from the cost efficiencies and the rapid time to market that the solution delivers for next-generation services."The flexible architecture of the CSM5000 provides resource mapping of up to 64 forward link channels and 32 reverse link channels and provides base station manufacturers with an increase in the number of possible simultaneous calls per channel card. In addition, the channel card power consumption per call is greatly reduced, enabling design of very compact base stations. Each channel element performs CDMA searching, CDMA modulation and demodulation and Viterbi and Turbo decoding.The CSM5000 represents a new modem architecture for the CSM family, enabling an increase in integration, while reducing host processor loading and system power consumption. The CSM5000 integrates an ARM7™ microprocessor for reverse link processing and provides a PowerPC™ compatible synchronous interface. To support cdma2000 Phase Two, a follow-up chip is planned for introduction subsequent to the CSM5000, which will be fully backward compatible with cdma2000 Phase One, and IS-95A and IS-95B systems.CSM5000 Features Features of the CSM5000 chip include:

  • RTT: Supports Radio Configurations one through five of cdma2000 (1-5 forward link, 1-4 reverse link);
  • Six-Sector Support: Increases the number of sectors supported from three to six, with support for six transmit antennae and up to 12 receive antennae;
  • Orthogonal Transmit Diversity Support: Support for three sectors with Orthogonal Transmit Diversity (OTD);
  • Increased Cell Radius: Accommodates cell radius up to 125 km;
  • Turbo Code Support: Allows Turbo codes or convolutional codes to be selected on a per-user basis;
  • Fast Power Control: Supports 800 Hz power control on both the forward and reverse links;
  • Quick Paging Channel: By transmitting a Quick Paging Channel on the forward link, the Quick Paging Channel increases the amount of time a mobile unit can stay asleep while in slotted paging mode, improving standby time of the mobile unit;
  • Integrated RISC Processor: Includes an ARM7 processor, used for many of the low-level reverse link tasks including searching, multi-path tracking and finger assignment, and frame rate and length determination thereby drastically reducing the load on the host processor;
  • Device Driver Software: Runs on the host processor and abstracts the low-level hardware details from the upper-layer CDMA applications. The software provides the following functions: download ARM firmware; run CSM5000 self-test functions; CSM5000 timing management; sector management; and drivers for Pilot, Sync, Paging, Access, and Forward and Reverse Link Traffic Channels;
  • 2.7v-3.3v I/O;
  • Available in a 352-pin Ball Grid Array package.
