    A pretty common question (and one I'd like answered) is, "which service has faster data speeds?" I'd like to suggest that this thread be used to gather some facts about data speeds.

    If we can agree on a standard test, such as using Blazer to hit http://dslreports.com/mspeed, then I think this thread will be of great value.
    If the mods agree, you can sticky it, and perhaps post the top speeds for each carrier somewhere at the top?

    So, let me kick it off. Time and date will be in the post itself.

    Carrier: Sprint
    Device: T650 1.08
    Location: NYC (Union Square).
    Signal: 3-4 bars.
    Test Results:
    5k: .891 sec - "unstable, too fast a result"
    50k: 3.41 sec - "unstable, too fast a result"
    100k: 8.106 sec - 119 kbit/sec
    200k: 15.806 sec - 110 kbit/sec
    600k: 41.025 sec - 121 kbit/sec

    I guess I will add to this thread

    Carrier: Cingular
    Device: T650 1.04
    Location: Apollo Beach, FL
    Signal: 2-4 bars
    Test Results:
    5k: 1.5 sec - "unstable/too fast a result
    50k: 10.014sec - 48kbit/sec
    100k: 14.656 sec - 62kbit/sec
    200k: 21.25 sec - 83kbit/sec
    600k: 51.963 sec - 96kbit/sec

    It would seem that mine get progressively better the more data is streaming to the device...not sure why that is...but that is what the data says.

    Carrier: Rogers
    Device: T650 GSM 1.05 ROW
    Location: Toronto (Queen and Church)
    Signal: 2-3 bars.
    Test Results:
    5k: 8.695 sec - 6Kb/s
    50k: 13.182 sec - 36Kb/s
    100k: 23.036sec - 38 kbit/sec
    200k: 44.047 sec - 38 kbit/sec

    Carrier: Sprint
    Device: T650 1.08
    Location: Manhattan (Wall Street)
    Signal: 3-4 bars
    Test Results:
    5k: <1 sec (Unstable/too fast - both of two tests)
    50k: ~3 sec (Unstable/too fast - both of two tests)
    100k: 8.610 sec - 118 kbit/sec (best of two tests, but both very close)
    200k: 15.835 sec - 113 kbit/sec (best of two tests, but both very close)
    600k: 41.663 sec - 120 kbit/sec (best of two tests, but both very close)

    These results are significantly dependent on signal strength. At my house (0-1 bar), I get much slower transfer rates.

    There are a few similar threads like these...

    Here is one

    True, but I like this thread better since it's a little more scietific (how many bars you have, different size files, etc). Let's make this one the official 650 one.

    Taking another look at the results its strange to see that although I had only 2 bars max, my results were in line with everyone else on sprint, so it begs the question, does Sprint choke the speed to the points that connection quality does not matter?

    Hmmmmmmmmmmm.

    Mine hiccups (ie, pause during download, then resume) more when my signal is weak. Before and after the pause, it runs at normal speeds. The pause(s) is what results in longer download time and overall worse rate.

    This is called "TCP slow start." When one machine sends data to another over the internet, it begins by sending it at a slow rate. It gradually speeds up as long as the receiver sends acknowledgements that it is getting all the packets. It will slow down again if congestion or other issues are a problem.
    Overall result: short files never reach maximum bitrate. Hence the trend observed in your test.

    Carrier: Sprint
    Device: T650 1.08
    Location: San Marino, CA
    Signal: 1-2 bar (Indoors on top floor)
    Test Results:
    5k: 2.179 sec - "unstable, too fast a result"
    50k: 8.041 sec - 62 kbit/sec
    100k: 10.508 sec - 93 kbit/sec
    200k: 19.184 - 93 kbit/sec
    600k: 67.741 sec - 68 kbit/sec

    Note the 600k speed...the first time I ran it, it was only 47kb/s...ran it two more times, and it was better, but no where near what 200k and 100k were. My signal is rather weak (two bars at best).

    Carrier: Cingular
    Device: T650 1.04
    Location: Washington, DC
    Signal: 4 bars (Indoors on top floor)
    Time: ~2:15PM
    Test Results:
    5k: "unstable, too fast a result"
    50k: 7.499 sec - 70 kbit/sec
    100k: 10.155 sec - 146 kbit/sec
    200k: 16.525 - 108 kbit/sec
    600k: 37.318 sec - 135 kbit/sec

    I included the time as well, because I suspect that might indicate the kind of load the network is getting (though I don't know anything about it technically).

    I got 155kbit/sec a few nights ago around 10PM.

    Interesting to see the variation. Some enterprising person could probably plug these into some kind of statistical formulas to get the mean, high, low, etc. (no, I'm not offering).
    I'm a little surprised to see that Edge sometimes has the edge (pun intended) over Sprint as far as speed.

    Now, how much real world difference is there between 115-120k and 144-145k?
    I can tell you that DUN using bluetooth on the Sprint T650 feels faster than my previous dialup (Verizon with a VX6000). I am still tempted to test a Cingular device but time is running out on me.
