  • "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.

      Getting 1029kbps down and 170kbps up in North Central Texas with my i4. Not great but a lot better than Edge that we used to have.

      One of the mods on here knows where I live (I forgot who though)
      That would be stupid. While everyone else is working on their 4G (Sprint, Verizon, even T-Mobile), you want AT&T to work on their 3G? Yea their 3G sucks balls, but come on.

      Anyways, I'm in Denver and my max so far is 550 down.

      Did not believe it until I read this article and tried the speed test. Sure enough:

      The difference between my iPhone 3G and my iPhone 4 is amazing.

      iPhone 3G consistently got 800-1000 kbps down and 300-500 kbps up on the cell network here in Springfield, MO.

      iPhone 4 now gets 2500-4450 kbps down and 800-1300 kbps up. BAM!

      WiFi is even better ... used to get 4500-6000 kbps down; now I get 9000-10000 kbps! Upload on WiFi remains the same as the upload on cell for me, though.

      989kbps download
      555kbps upload

      I live in Boston. But I get crappy reception in my condo.

      Off topic: How do I edit, quote, and add photos to posts? Can this be done from the iPhone?

      I thought we were saving the "3.5G" moniker for HSPA+ so that we can take the high-road while complaining about T-Mobile calling their HSPA+ "4G speeds." What gives?
