Where Are We Today ?Analog networks have migrated to digitalHandset volume growth outstrips PCs almost 4:1Subscriber base has grown to almost 700 millionConnectivity is a major part of emerging devices-Including handsets– Always connected-internet everywhere
Still a voice-centric network operation today, but data capabilities are emerging– – 2.5G interim evolution: GSM (GPRS), CDMA (IS-95B, 1x),– TDMA (IS-136+)– – 3G revolution will occur in multiple stages
We are just at the starting line.

The Promise of 3GThe Promise of 3G
Higher bandwidth capability– 144-384 Kbps at mobile speeds– 2 Mbps at fixed locations (ITU spec)– 10-20 Mbps using HSDPA (3.5G)
Future broadband applications/services– Internet browsing (WML, HTML)– Audio/video streaming multimedia (MP3, MPEG, H.3XX)– Location based services (GPS), e-commerce, push software
technologies (ASP), and much more...Migration path from 2G and 2.5G technologiesVoice/data convergence will shake up the market as wireless world merges with IP and computing worldWorldwide coverage eventually4G will be for 100 Mbps after 2010

Chip Vendor Success FactorsChip Vendor Success FactorsBalanced solution: low power, high performance, low cost, targeted at several consumer form factorsTier-1 OEMs still drive the market, but tier-2/3 and start-up OEMs building momentumDrive Standardization:– Offer interoperability with other offload chips (GPS,
Bluetooth, etc.) and multimedia application processors– Offer feature-rich and easy-to-use software
development environment and tools– Offer several packages to different OEMsPartnerships and collaboration critical to successBranding activities become common
4/25/2003 Wiscom Technologies 24
WCDMA dominates in IMTWCDMA dominates in IMT--2000 (3G)2000 (3G)WCDMA– Pushed by Japanese players and GSM players– Will dominate based on GSM current footprint (~65%)
Cdma2000– A natural path for IS-95 CDMA players– Limited growth due to current limited IS-95 footprint (~12%)
TD-SCDMA– One option of TDD mode (1.28Mcps)– “home-grown” and with strong political support in China– less interest outside China
EDGE – Original GSM interim step, barely meets 3G need, viewed as 2.5G– Diminishing support from TDMA (IS-136) players (~ 8%)

Major PHY Differences between Major PHY Differences between WCDMA and cdma2000WCDMA and cdma2000
Synchronization Between Base Stations– WCDMA uses asynch BTS → need cell search for
initial synch and soft handover
Operating Bandwidth and Chip Rate– WCDMA operates at 3.84Mcps over 5MHz
Channel Structure and Rate Flexibility– WCDMA introduces TrCH concept for varieties of rate
and QoS flexibilities– WCDMA rate information can be obtained via TFCI

FPGA to ASIC vs. Straight to ASICFPGA to ASIC vs. Straight to ASICIf straight to ASIC,– Functional simulation & verification can not realistically cover all the
real cases or will take an unrealistic time to finish– Back annotation simulation will also be very slow and take a lot of
resources
Via FPGA– Design easily testable and modifiable in actual hardware– VHDL code is portable for most of the design– Parallel software development via on circuit board external DSP and
Micro-processor– Make early lab test and field trial possible for design proof and
optimization
