Verizon begins throttling iPhone unlimited 3G customers

We can’t say we weren’t warned, since Verizon updated its data policy way back in February, but it’s still a punch in the gut to hear its “network optimization” plan went into effect yesterday. A new policy page pointed out by Droid-Life explains how the policy will affect only the “top 5 percent of data users with 3G devices on unlimited data plans” (LTE and tiered data users are in the clear) by managing their speeds when connected to towers it has deemed are congested. Those conditions, termed network intelligence by Big Red, are what it feels separates this scheme from mere data throttling since it will only affect a few users (those consuming 2GB or more of data per month) at certain times and places, but it’s hard to see it any other way. If you’re one of those affected, expect a message on your bill or My Verizon account, although you may go into and out of the affected group depending on your usage. Hit the source link below for all the details — anyone else think it’s not a coincidence this policy popped up just before the iPhone 4 came to Verizon and is being implemented only weeks before the next iThing is expected to arrive?

AT&T raises iPhone tier on October 4th, Maybe iPhone 5 launch date?

We’ve just been handed some internal AT&T information on device changes:

A new tier of device will be created in AT&T’s phone database on October 4th (a Tuesday:) which will require a higher rate of insurance. iPhone (and other devices) will move there on the arbitrary October 4th date. It is curious that the iPhone was mentioned specifically and not other devices.

See that screen there? That’s from the minty fresh beta 4 of iPhone OS 4.0, which was just released to developers moments ago. Unless our eyes are badly mistaken, that’s an option to setup internet tethering on AT&T, something that WWAN warriors have been waiting for since… oh, forever. We’re downloading the new build as we speak, and we’ll let you know if we find anything out. Oh, and don’t get your hopes up too high — AT&T proclaimed that it was “still waiting on better network performance” before enabling iPhone tethering just three weeks ago.

AT&T On Top Again On 3G Wireless Performance Test

 News  Comments Off on AT&T On Top Again On 3G Wireless Performance Test
Feb 232010


AT&T says it has worked hard to improve its much-maligned 3G network over the last eight months–erecting hundreds of new cell towers, using better-performing wireless spectrum, and souping up its cell sites across the country–and the results of our latest 13-city 3G network performance tests suggest that the network has indeed undergone a drastic makeover.

After registering the lowest average download speeds in our 3G performance tests last spring, AT&T’s network turned in download speeds that were 84 percent better than the numbers from eight months ago; in our latest tests, AT&T’s download speeds were 67 percent faster on average than those of the other three largest U.S. wireless providers–Sprint, T-Mobile, and Verizon.

In our tests last spring, AT&T posted an average download speed of 818 kbps (kilobits per second) across 13 cities. In our tests conducted in December 2009 and January 2010, AT&T’s average download speed increased to 1410 kbps.

AT&T’s download speeds in New York City were three times faster in our latest tests than in our tests last spring; in San Francisco, the AT&T’s download speeds were 40 percent faster.

The AT&T network’s reliability improved dramatically, too: Last spring, PCWorld testers obtained a usable broadband connection with AT&T only 68 percent of the time. In our latest tests, testers connected to AT&T successfully in 94 percent of their attempts.

Verizon Wireless, which turned in the best all-around performance in last spring’s 3G network testing, and Sprint, which finished a close second, both continue to perform well, according to our latest test results. Our tests found that Sprint’s network delivered download speeds nearly identical to those we measured eight months ago in the 13 test cities; Verizon’s download speeds decreased by 8 percent overall.

In the past year, Sprint and Verizon–like AT&T–have seen a marked increase in the number of 3G smartphones that rely on their networks. Our speed results suggest that Sprint is upgrading its network capacity fast enough to meet the demand, while Verizon may be having trouble keeping up. Nevertheless, both networks’ reliability (the likelihood that a user can connect to the Internet at a reasonable speed) improved in the most recent tests over how they fared last spring.

We tested the T-Mobile 3G network for the first time in December and January, and found that it supported download and upload speeds that were competitive with Sprint’s and Verizon’s in most of our test cities. In one city–New York–T-Mobile’s network even delivered download speeds that are usually associated with 4G networks.

Before getting into the details of our test results, a few words about the testing and the data. During December and January, PCWorld and our testing partner, Novarum Inc., tested the download speeds, upload speeds, and network dependability of the AT&T, Sprint, T-Mobile, and Verizon 3G networks from 20 locations in each of 13 U.S. cities. Altogether we ran more than 51,000 separate tests covering 850 square miles of wireless cell coverage servicing 7 million wireless subscribers (see “How We Do the Testing”).

At each testing location, we connected to the 3G network via both laptops and smartphones. The laptop tests accurately measured the capacity and performance potential of a given network, while the smartphone tests approximated the real-world connection speeds users of these popular devices might experience, given the less-powerful processors and 3G radios that the devices contain.
Reading the Charts

The charts list the cities in the leftmost column; moving rightward across the chart, you can see the speed averages and reliability scores in that city for each of four 3G wireless networks. Speeds are expressed in kilobits per second (kbps); the figure for reliability represents the percentage of the total number of 1-minute tests we conducted of a given carrier’s service during which the service maintained an uninterrupted connection at a reasonable speed.

Because we couldn’t test every city in the country, we chose 13 that are broadly representative of the rest: Baltimore, Boston, Chicago, Denver, New Orleans, New York City, Orlando, Phoenix, Portland, San Diego, San Francisco, San Jose, and Seattle. Because wireless signal quality depends to a large extent on variables such as network load, distance from the nearest cell tower, weather, and time of day, our results can’t be used to predict specific future performance in a specific area. Rather, they illustrate the relative performance of 3G service in a given city on a given day. Each speed number possesses a margin of error of plus or minus 5 percen.
