HSDPA - High Speed Downlink Packet Access

HSDPA improves system capacity and increases user data rates in the downlink direction, that is, transmission from the Radio Access Network to the mobile terminal. The processes of adaptive modulation and coding, the procedures by which HSDPA data is scheduled for transmission across the air interface and improved re-transmission patterns all contribute to the improved data rates.
