HSDPA Highlights
• Integral part of WCDMA standard (3GPP Release 5)
• Higher bit rates: 2 - 14.4 Mbps
• Higher system capacity: 2 - 3 times compared to R99
• Lower latency (round trip delay) compared to R99
• Wide area coverage with full mobility
• No need for extra spectrum bandwith
• Voice and Data on same carrier

Broadband Wireless Access Technologies
HSDPA
- top speeds of up to 14.4 Mbps
- suited for wide area coverage
- spectrally efficient
- quick and cost effective upgrade of existing networks
- fully standardized – rapid time to market
- large addressable market
High speed, full mobility, already here
WiMAX (802.16x)
- speeds of up to 100 Mbps
- inefficient wide area coverage(3 times more sites to coversame area as HSDPA)
- less spectrally efficient
- standardization on-going
- opportunity still needs to beproven (cost effective back-hauling for Wi-Fi and WCDMA)
Very high speed, limited mobility, not ready for implementation
Flash OFDM (802.20x)
- speeds of up to 10 Mbps
- can be interesting for wide areacoverage if deployed in lower frequency bands (e.g. 450 MHz)
- not standardized yet
- theoretically addressing the same market as WiMAX
Very high speed, large mobility, standard under definition

Conclusions
• HSDPA is a natural evolution of UMTS
• HSDPA is a high speed fully mobile technology
• HSDPA offers up to 14.4 Mbps, lower latency, better spectrum efficiency
• HSDPA improves customer experience being suitable for asymmetric
services (as most Internet-like services are)
• HSDPA is the most advanced fully standardized broadband wireless access technology
