HSPA
Standardised by 3GPP, HSPA is the set of technologies that defines the migration path for 3G/WCDMA operators worldwide. HSPA, which uses the FDD transmission scheme, includes HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) and HSPA Evolved. These are also known as 3GPP Releases 5 through to 8.
Unlike many other mobile broadband technologies, HSPA provides very efficient voice services in combination with mobile broadband data.
In most HSPA networks, the end-user can expect to enjoy speeds of at least 1Mbps upwards, depending upon the peak speed of the network (anywhere from 1.8Mbps to 14.4 Mbps) with peak uplink speeds of up to 5.7Mbps.
HSPA Evolved
HSPA Evolved introduces MIMO (Multiple-Input, Multiple-Output) capabilities and higher order modulation (64QAM), enabling greater throughput speeds and higher performance. The first HSPA Evolved services are expected to be deployed at the end of 2008.
