High Speed Data Market Snapshot
• To fulfill the “promise of 3G,” carriers must deliver high speed data User experience that far exceeds 2G
• HSDPA is what the market is waiting for …
… and it’s right around the corner!
![Page 12: Analyze Assure Accelerate TM Spirent Communications Overview](https://reader035.vdocuments.us/reader035/viewer/2022062800/56649e155503460f94afeec9/html5/thumbnails/12.jpg)

Getting to HSDPA
• Carriers are just starting meaningful commercialization of R99…
• …but there are still a lot of challenges related to R99: Inter-RAT handovers
Handset performance characterization
Energy management
• At the same time, HSDPA deployment schedules are accelerating.
![Page 13: Analyze Assure Accelerate TM Spirent Communications Overview](https://reader035.vdocuments.us/reader035/viewer/2022062800/56649e155503460f94afeec9/html5/thumbnails/13.jpg)

HSDPA Functional Testing
• HSDPA is significantly different from R99
R99 HSDPA
Largely focused on dedicated channel (DCH)
Shared channel (HS-DSCH)
Fast power control Fast rate control
QPSK modulation Adaptive modulation
Slow retransmissions, high latency Fast retransmissions, low latency

HSDPA Functional Testing
• There are a limited number of HSDPA RF Conformance tests TS34.121 Section 9 – six minimum performance tests (6/05)
• BUT… Key HSDPA aspects are not conducive towards conformance testing MAC-hs scheduler – not defined in the standard
Performance is highly dependent on traffic load
Mobility management
• HS ↔ HS handovers (intra and inter-cell)
• HS ↔ R99, 2G handovers
![Page 15: Analyze Assure Accelerate TM Spirent Communications Overview](https://reader035.vdocuments.us/reader035/viewer/2022062800/56649e155503460f94afeec9/html5/thumbnails/15.jpg)
Analyze Assure AccelerateTM
HSDPA Functional Testing
• Conformance comprises 10-20% of an HSDPA test plan Static conditions for basic functional verification
• For the rest, a flexible network emulator is required Capable of capturing true real-world scenarios
Maintaining ease-of-use
