HSDPA

( Duration: 2 Days )

The High Speed Downlink Packet Access (HSDPA) is a packet-based data service in W-CDMA downlink with data transmission up to 8-10 Mbps (and 20 Mbps for MIMO systems) over a 5MHz bandwidth in WCDMA downlink. HSDPA implementations includes Adaptive Modulation and Coding (AMC), Multiple-Input Multiple-Output (MIMO), Hybrid Automatic Request (HARQ), fast cell search, and advanced receiver design.

The HSDPA is based on W-CDMA evolution and is standardized as an element of the 3GPP Release 5 WCDMA specification, and is in fact the key new feature in this latest release. It is a backward-compatible extension of the basic UMTS Rel’99 specifications that supports voice, mixed voice/data and real-time services, all on a single carrier.

The HSDPA Training course provides you with a comprehensive business and technical foundation in HSDPA migration paths, services and applications development. It offers an overview of the High Speed Downlink Packet Access (HSDPA) technology. HSDPA enhances the packet data services provided in W-CDMA (UMTS) by increasing the data throughput and reducing unwanted delays and it allows carriers to increase downlink throughput over W-CDMA links.

The HSDPA workshop is designed to provide a general overview for strategic or technical managers, consultants, communications professionals, software engineers, system engineers, network professionals, marketing and sales professional, IT professionals, and others who plan on using, evaluating or working with UMTS and HSDPA networks, applications and services.
