High-Speed Uplink Packet Access (HSUPA) is a 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher upload data transfer speeds.

The High-Speed Uplink Packet Access (HSUPA) protocol works with the 3G mobile telephone network, providing a maximum uplink speed of 5.76 megabits per second (Mbps). HSUPA is a part of the High-Speed Packet Access (HSPA) software family of protocols, maintained and defined by the 3rd Generation Partnership Project (3GPP). The 3GPP group, made up of numerous telecommunications associations, is involved in creating specifications for the 3G mobile phone system. Among its services, 3G allows simultaneous transfer of both voice data and non-voice data. To make use of HSPA protocols, you must have a mobile device that is HSPA-enabled. HSUPA improves the performance of the enhanced dedicated channel (E-DCH) by increasing throughput and reducing delays. In other words, it increases the speed at which your mobile device can communicate with the network. The HSUPA is designed to quickly match the signal and protocol parameters required for wireless communications, also known as link adaptation.

HSUPA(High Speed Uplink Packet Access) is another release to the evolving 3GPP standards. HSUPA employs an extremely efficient procedure for sending data on the uplink channel. The theoretical speed for data on the uplink is 5.76Mbps and the downlink will achieve HSDPA theoretical speeds of 14.
