High Speed (Downlink/Uplink) Packet Access (HSPA/HSDPA/HSUPA)

A combination of two mobile telephony protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), which extend and improve the performance of existing Wideband Code Division Multiple Access (WCDMA) protocols. HSPA supports increased peak data rates of up to 14 Mbit/s in the downlink and 5.8 Mbit/s in the uplink. It also reduces latency and provides 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 compared to original WCDMA protocols.
