Glossary Detail HSDPA
High-Speed Downlink Packet Access

An upgrade for WCDMA / UMTS networks. It doubles network capacity and increases download data speeds five-fold or more.

While the technology is theoretically capable of downlink (download) data rates up to 8-10 Mbit/s (million bits per second), initial deployments and devices will be limited to 1.8 Mbit/s, followed by network upgrades and new devices capable of 3.6 Mbit/s.

HSDPA is standardized by the 3GPP in UMTS Release 5.
