WCDMA stands for Wideband Code Division Multiple Access.
HSDPA (High Speed Downlink Packet Access)

1. WCDMA is commonly referred to as 3G, while HSDPA is commonly referred to as 3.5G.

2. HSDPA provides much higher data rates compared to WCDMA.

3. HSDPA has lower latency times compared to WCDMA.

4. HSDPA has Fast Packet Scheduling and AMC, features that are absent in WCDMA.

5. HSDPA allowed speeds above 384kbps, the most notable of which is 3.6Mbps and 7.2Mbps,      Whereas WCDMA networks were only capable of reaching speeds of 384kbps
