  • AT&T Will Speed Up Your Uploads... Slowly


    AT&T announced today that they would start rolling out a patch for the upload speed problems that have been plaguing numerous iPhone 4 users throughout the US. AT&T identified the issue as a software bug in equipment used in certain areas of their network, and released a workaround to improve speeds while the patch to fix the bug was being developed. A spokesman for the carrier said today that the patch would be phased in over the next two to three weeks.

    Around the July 4th holiday, new iPhone 4 owners noticed that their uploads - which had in some cases increased by as much as 10 times over iPhone 3G/S speeds - suddenly crashed. Reports of upload throughput below 100 kb/s were common, and some users suspected AT&T was capping their uploads to save its network. However, the carrier insisted that it was not doing traffic limiting, and said that Alcatel-Lucent equipment had a bug that crippled devices running the High-Speed Uplink Packet Access (HSUPA) protocol. On AT&T's network, the only HSUPA devices are the iPhone 4 and some of the cards used with the carrier's LaptopConnect service.

    AT&T released a workaround to the Alcatel-Lucent bug that allowed 3G uploads up to 384 kb/s, better than the 100 kb/s some were experiencing but still much less the 1.5 to 2 Mb/s many users had gotten before the bug. "The patch will be deployed on a phased basis over the next two to three weeks," according to AT&T spokesman Mark Siegel. The Reuters article on the AT&T announcement promises "a potential maximum of 5.67 gigabits per second" after the patch is applied; we're pretty sure they meant "megabits."
