HSPA

(High Speed Packet Access) A family of high-speed 3G and 4G digital data services governed by the 3rd Generation Partnership Project (3GPP). Deployed by GSM cellular carriers, at the end of 2014, nearly two billion subscribers were using HSPA worldwide. Although based on WCDMA, HSPA is a major enhancement with more channels and enhanced modulation schemes. In addition, HSPA can recover faster from errors (see HARQ).

First deployed in the U.S. in 2005, subsequent HSPA+ (HSPA Plus) releases added support for multiple antennas and was designated as a 4G technology by the ITU (see MIMO). See LTE, 4G, 3GPP, DC HSPA, cellular generations, cellular vs. Wi-Fi, WCDMA, TDMA and GSM.

Support for 3G HSPA and 2G EDGE
When this iPhone 3G was in range of a 3G cell tower, it used HSPA. However, it throttled down to the EDGE (E) channel when 3G was not available.
