But until then, a 3G technology called High Speed Packet Access, or HSPA, is seeing the big growth numbers around the globe.

Sam Diaz, Growth of 3G wireless broadband illustrates demand for 4G connections

HSPA is a general name for the High-Speed Downlink Packet Access (HSDPA) and High-Speek Uplink Packet Access protocols. They are packet-based mobile telephony protocols used in 3G to increase data capacity and speed up transfer rates. One of the primary differences between HSPA and EV-DO networks is that HSPA allows mobile handsets to transmit voice and data simultaneously.

Jonathan Morgan has written a very interesting post explaining why HSPA is so important.  It all comes down to dollars.
