HSDPA - High Speed Downlink Packet Access
High Speed Downlink Packet Access is a feature of Releases 5 and 6 of UMTS and of W-CDMA (Wideband CDMA) which will allow downstream packet data at between 4 and 8 Mbps (and potentially 20 Mbps for MIMO systems) over a 5MHz bandwidth in WCDMA downlink, by introducing a package of technologies: new radio modulation techniques, fast hybrid ARQ, channel dependant scheduling, advanced receiver design and by using several channel codes in parallel.
HSDPA also abandons the concept of power controlled data channels for these new channels. Fast cell search is also a feature of HSDPA.
Benefits of using HSDPA compared with the basic UMTS standard include:
- Up to three times increase in spectral efficiency
- Typically 3x the data throughput
- Peak data rates of up to 10Mbps compared to 2 Mbps for basic UMTS
- Reduced end-to-end latency.
Course benefits
This unique HSDPA training course delivered in the UK by LEVER Technology Group PLC, Europe's leading company for training in Wireless technologies, explores each of these components of HSDPA in detail, explaining how they work in synergy to create this major step forward for UMTS.
Delegates with existing knowledge of the architecture and operation of UMTS networks will find this course invaluable in understanding the components, operation and the technical issues involved in deploying HSDPA in UMTS networks.
Pre-requisites
Before attending the HSDPA training course, delegates must have a sound understanding of the architecture and operation of UMTS networks.
One or more of the following courses are recommended as a pre-requisite to this HSDPA course:
