AT&T Wins Gizmodo 3G Bandwidth Test

ink writes "Gizmodo has completed a 12-city test of 3G cellular bandwidth speed. Verizon won four of the twelve, however AT&T scored higher with six: 'Let's get this straight right away: We didn't test dropped voice calls, we didn't test customer service, and we didn't test map coverage by wandering around in the boonies. We tested the ability of the networks to deliver 3G data in and around cities, including both concrete canyons and picket-fenced 'burbs. And while every 3G network gave us troubles on occasion, AT&T's wasn't measurably more or less reliable than Verizon's.'"

      I find I can get a nice burst for the first couple of megabytes then Im throttled pretty badly. Id like to know which carrier doesnt do this. It doesnt look related to reception.

      Short answer: it seems that all US carriers do this, either because (i) they underestimated demand and under-invested in infrastructure, or (ii) because they can maximize their revenues while minimizing their costs, and the customers are trapped into long term contracts.
      This sort of throttling by carriers is unheard-of in more advanced countries, such as Finland or Sweden. None of the carriers do that here; if they tried it, they'd have no customers left within a month or two (terminating a contract is trivial, and does not entail penalties). There are no usage caps on 3G either - unlimited actually does mean unlimited.

      I agree, and this is why I have nothing but contempt for typical "best provider performance" conclusions that are driven solely by single-connection TCP transfer tests (e.g. speedtest.net).

      In most cases, latency matters more than bandwidth (where bandwidth is roughly the same within an order of magnitude or so). This is why there's a very strong correlation between the provider that had the lowest measured latency and the provider that had the lowest page retrieval time. In the end, real-world page loading is precisely what we use smartphones for, and so we need to know how that application performs, instead of what raw transfer rates are.

      I still think the Gizmodo tests are deficient, though, as they are unclear as to whether they repeated the tests at regular intervals over a 24-hour period. Network congestion varies throughout the day, and at any given moment one path may be more congested than another. A valid test, IMO, would take the average (or median) of each metric over a 24-hour period (or even longer, covering both a weekday and a weekend, since usage varies among them).

      I'd be curious to see the results of a test conducted as follows:

      Setup a test rig that automatically tests download speed and latency from a few different servers (globally dispersed) every 30 seconds. Have it geotag each result.

      Drive around each of the cities (and metro area surrounding them), and gather the data over a few days for each city.

      Then, compute a few different metrics. First, for each carrier, generate a heat map of download speeds (It would wind up looking something like Verizon's 3g Map, but with different colors denoting speed ranges). If there are multiple readings in a given area (Say 100m^2), average them.

      Second, figure out the peak speed, minimum speed, average speed (Both mean and RMS) as well as the standard deviation for each carrier.

      There's so much focus on peak speed these days (well, at least that's what gets the press), that I think people forget that what matters is the average experience.
