AT&T users complain of slowing 3G upload speeds

updated 11:00 am EDT, Tue July 6, 2010

ATT users seeing reduced mobile uploads


Multiple reports from AT&T subscribers have complained that their 3G upload rates have plummeted in recent days. Those who had uploads as quick as 1Mbps just days ago are now seeing speeds of 100Kbps or less. Tests from GigaOM have largely been limited to iPhone owners and have made it difficult to tell if the issue is independent of any one device.

AT&T has already been contacted regarding the slowdowns but hasn't responded as of this writing.

The carrier's HSPA network is primarily oriented towards downloads at 7.2Mbps downstream, but it has normally been capable of 1.5Mbps and in some cases more, depending on the device. Apple's iPhone 4 is one of the fastest as it uses a newer chipset. AT&T isn't known to fully support the HSUPA (High Speed Upload Packet Access) standard on its network, so it can't reach the peak 5.8Mbps upload speeds the iPhone 4 can handle.

    I can confirm this.

    Last week I was getting 3.5mb down and 1.6mb up and now I am getting 1.7mb down and 96kb up from the same location. :(

    Slow - Ummm

    Drop almost 2 million new iPhones on AT&T's Network and what would you expect.

    Upload 3G iPad

    I'm in Mt.Laurel NJ and highest upload I've gotten ~ 3 PM is 58K on my iPad. Most trials it was far less. Download max was 267Kb.

    Except since 77% of those iPhones were iPhone upgrades, you're not really adding another 2 millions phones to the network (and that's not counting any other smart phone owner upgrading).

    But thank god!

    Man, can you imagine how much slower these downloads would be if there were an iPhone available on Verizon and T-Mobile? I mean, with all those people dropping ATT faster than the iPhone drops a call, the network would be even more clogged!

    Oh, wait, it would be the other way around, wouldn't it. Well, let's just thank god that Apple didn't cripple an iPhone with a lousy CDMA chip in it. Much rather cripple it with a lousy network instead!

    No difference.

    I have seen no real difference, in fact areas where i used to get no data service i get fairly fast service now. I think they may be redeploying spectrum to even everything out in preparation for their next network upgrade.
