  • "3.5G" iPhone 4 Blazes (Where Supported)


    With little fanfare, Apple has added High-Speed Uplink Packet Access (HSUPA) support to the iPhone, and it significantly improves performance. A report in ZDNet over the weekend indicated about 60% faster downloads and a 500% in upload throughput. The results will vary depending on the support for HSPA on the local AT&T cell: in Boston, I'm getting about double the download throughput I used to get with my iPhone 3G, and somewhere between eight and ten times the upload. Zowie.

    The iPhone 4's support for HSUPA as well as High-Speed Downlink Packet Access (HSDPA, which was also supported by the iPhone 3GS) makes it Apple's first "3.5G" phone. AT&T is using HSPA as an evolutionary step towards its 4G LTE network which will begin deployment in 2011. The carrier has begun testing its advanced 3.5G network, capable of up to 7.2 Mbps downloads, in six cities - Charlotte, Chicago, Dallas, Houston, Los Angeles and Miami - with 19 more to come by sometime this year. HSUPA adds an additional transport channel called the Enhanced Dedicated Channel (E-DCH), which will allows for uploads as fast as 5.8 Mbps.

    ZDNet did their testing out in Louisville, Kentucky which - though not a major city - has a solid network: they saw downloads in the 2 to 4 Mbps range and uploads consistently around 700 Mbps. Gizmodo tested the iPhone 4 in New York, with its notoriously congested network, and still found 5 to ten times improvement in uploads.

      However, I am in my 6th floor apartment in the loop in between 2 high rise buildings, so maybe that's partly the reason for the slower speeds than others in Chicago.

      Why would you need a "phone" to have fast d/l speeds? I mean its not like youre seeding a bunch of torrents off the damn thing Lmao

      fast dl speeds is important for anything u do on your phone pretty much. Such as streaming video / browsing etc.

      The upload speed is the portion that would pertain to seeding on torrent.

      Any chance this is just a software thing and my iPad 3G can do this eventually? Cause I'll be honest, I don't have some screenshots to post right now but I barely get a fraction of the speeds the rest of you get.

      My best ever speeds over 3G using SpeedTest:
      Download: 385KB/s
      Upload: 40KB/s



      EDIT: And just to clarify, those are my BEST EVER speeds, typically I get ~85KB/s down and ~16KB/s up.

      Just wish the latency wasn't so bad. I'm getting 2-3mbps and 1-1.6mbps but latency is like 1000ms

      I don't think anyone here is interested in WiFi speeds (802.11g and 802.11n), we're interested in cellular speeds over 3G: the speeds that AT&T provides, not your home internet connection.
