High Speed Packet Access (HSPA) is an amalgamation of two mobile telephony (http://en.wikipedia.org/wiki/Mobile_telephony) protocols (http://en.wikipedia.org/wiki/Communications_protocol), High Speed Downlink Packet Access (HSDPA (http://en.wikipedia.org/wiki/HSDPA)) and High Speed Uplink Packet Access (HSUPA (http://en.wikipedia.org/wiki/HSUPA)), that extends and improves the performance of existing 3rd generation mobile telecommunication networks utilizing the WCDMA (http://en.wikipedia.org/wiki/W-CDMA_(UMTS)) protocols. A further improved 3GPP (http://en.wikipedia.org/wiki/3GPP) standard, Evolved HSPA (http://en.wikipedia.org/wiki/Evolved_HSPA) (also known as HSPA+), was released late in 2008 with subsequent worldwide adoption beginning in 2010. The newer standard allows bit-rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink. However, these speeds are rarely achieved in practice.
