WCDMA is evolving to enable higher bit-rates and throughput. The first step is to improve the downlink by introducing High Speed Downlink Packet Access (HSDPA). The second step is to improve the uplink by introducing Enhanced Uplink. Together these two technologies are known as High Speed Packet Access (HSPA).

HSPA improves the end-user experience by:
- increasing peak data rates to 14 Mbit/s in the downlink and 5.8 Mbit/s in the uplink
- reducing latency
- providing up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit

These capabilities will benefit operators by providing higher performance, and improving end-user experience for web access, file download/upload, voice over IP (VoIP) and streaming services.

HSPA makes mobile/wireless broadband a reality.
