Course 520: Advanced HSDPA

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

Advanced HSDPA training course provides you with a comprehensive technical foundation in HSDPA analysis, design, implementation and testing (RF and MAC layers applied to mobile device, Node B (BS) and RNC)
