HSPA

Overheard - High Speed Packet Access

It’s no secret that 4G wireless technology - aka Long Term Evolution and WiMax - is in the works and actually starting to see some deployment. But until then, a 3G technology called High Speed Packet Access, or HSPA, is seeing the big growth numbers around the globe.

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.
