What’s after HSDPA? HSUPA, of course


Wow, we don’t even have HSDPA 3G close to rolled out and the next level isn’t that far behind. If HSDPA and HSUPA sound like funny acronyms, they are, so let’s give you the 40,000-foot view to get you up to speed (literally!). HSDPA stands for High-Speed Downlink Packet Access and is a cellular wireless technology that provides speedy upload and download speeds to the tune of up to 3.6 Mbps down and 385 Kbps up. HSUPA is the next-step and promises double the download speed (7.2 Mbps) while quadrupling the upload to 1.5 Mbps.

Now that you don’t have to buy a vowel to understand the two technologies, this tidbit might make sense: Qualcomm will be demonstrating HSUPA technology at the ITU Telecom show in Hong Kong. None of the U.S. carriers have committed to HSUPA, but Cingular is currently rolling out HSDPA; it’s a safe bet that if any carrier will bring HSUPA to the U.S., it would likely be Cingular in the next few years.
