What the hell is… HSDPA? Published by Stuart Dredge It’s another darn mobile acronym, that’s what it is. But it’s actually quite exciting if you’re into mobile content. To take the basics first, HSDPA stands for High-Speed Downlink Packet Access, although it’s probably easier to think of it as ‘mobile broadband’ or ‘3.5G’.
In short, it’s an upgrade to the operators’ 3G networks that gives you more bandwidth, making it faster to get content â€“ whether that’s streaming video and music, or downloading games, video or music.
As a rough guide to what it means in the real world, while 3G currently gives you around 384 kilobits per second, HSDPA will allow 1.8 megabits per second for most of the handsets that the operators will launch later this year, although this will go higher in the future.
All the operators are upgrading their 3G networks to HSDPA, with 3 announcing last week that the first handsets would go on sale before Christmas. So what does it mean for mobile content? Well, for music, it means the operators will be able to start selling you full albums rather than individual songs.
Meanwhile, for video, it will improve the quality of streaming video, while making video downloads much faster. It’ll either be quicker to get content, or the operators will be able to up the quality, and get rid of some of that unattractive pixelisation that you see even on a 3G connection.
It doesn't matter if you have Web'n'Walk, Web'n'Walk plus, or Web'n'Walk Max attached to your tariff you will always connect at the fastest available speed that is available in your location. That means that because the Diamond/Compact IV have HSDPA ability where possible it will connect using the fastest connection it can
