Standardised by 3GPP, HSPA is the set of technologies that enables 3G/WCDMA operators to upgrade their networks to run at broadband speeds. HSPA includes HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) and HSPA+.


Unlike many other mobile broadband technologies, HSPA supports the very efficient provision of voice services in combination with mobile broadband data services.

In most HSPA networks, the end-user can expect to enjoy data throughput speeds of at least 1Mbps, with actual performance varying according to local conditions and the peak downlink speed of the network, which can reach 14.4 Mbps, and the peak uplink speed, which can reach 5.7Mbps.


HSPA+ networks harness MIMO (Multiple-Input, Multiple-Output) capabilities and higher order modulation (64QAM) techniques, to run at even faster speeds, enabling theoretical peak data rates of up to 42Mbps.
