Article Suggests iPhone is to Blame for AT&T's Network Failures

A NY Times article suggests that the iPhone may be to blame for AT&T's network failures. Despite the fact that AT&T fell last on the list of Consumer Reports' latest annual cell phone satisfaction survey, the author claims that independent data suggests that AT&T may have "the superior network nationwide". Meanwhile, the iPhone, itself, may be contributing to the performance problems by causing interference that affect both its voice and data services.

Roger Entner, senior vice president for telecommunications research at Nielsen, said the iPhone's "air interface," the electronics in the phone that connect it to the cell towers, had shortcomings that "affect both voice and data." He said that in the eyes of the consumer, "the iPhone has the nimbus of infallibility, ergo, it's AT&T's fault." AT&T does not publicly defend itself because it will not criticize Apple under any circumstances, he said

AT&T has recently acknowledged that service in some major U.S. cities have been performing below standards and claims that AT&T is working on it. At no time has AT&T publicly blamed Apple for any issues.

John Gruber, however, questions the objectivity of the article as well as the "independent" sources of data, but also raises the most convincing argument against this probability:

If it's the iPhone's fault, not AT&T's, why aren't iPhone users around the world having the same problems as those here in the U.S.?

AT&T can't keep up with the saturation of data from iPhone users.

If exclusivity were with Verizon, the same issue would be occurring, and might even be worse.

The iphone is the beast of cell phones! I would be on the bus listening to a podcast. Next thing I'm on itunes buying tracks. Then I'm downloading apps. And the ease at which I do those things is staggering. No other phone even comes close to the iphone experience.

A possible answer to Gruber's question: maybe it's because AT&T has a much higher percentage of iPhone users? This explanation would be consistent with the observation that AT&T 3G service tend to be poor in New York and San Francisco, where everyone and their moms seem to have iPhones

John Gruber, however, appropriately questions the objectivity of the article as well as the "independent" sources of data, but also raises the most convincing argument against this probability: If it’s the iPhone’s fault, not AT&T’s, why aren’t iPhone users around the world having the same problems as those here in the U.S.?


Bingo. Article is rubbish.

A flaw that I see with this is the question of whether the data rating AT&T's network near (at?) the bottom in performance according to customer experience was so severely affected by iPhone users, which this article seems to suggest are the only ones really affected by bad network experience. I mean, even if every iPhone user said that the network satisfaction was the worst possible, what percentage of AT&T customers are actually iPhone users? If we were to suppose 10%, and, as the article suggests, the rest should find AT&T's network to be the best, then this would hardly pull AT&T all the way to the bottom of overall user satisfaction.

It seems clear that this issue isn't as clear cut as this article seems to be trying to make it out to be. While there may be some truth to the issue that they bring up, to blame all of AT&T's perceived network issues solely on the iPhone's "air interface" just doesn't ring true.

That points the finger back at AT&T, not the iPhone it self. He isn’t arguing that iPhone user’s excessive network use is not a reason why AT&T’s network is having these profound issues, just that the problem isn’t with the iPhone itself.

The iPhone 3G was criticized by AT&T's Ralph de la Vega and Kristin S. Rinne earlier this year for its inability to effectively filter noise from overlapping cell sites. I believe this is what Roger Entner is referring to when he criticizes iPhone's "air interface" (baseband).

According to Infineon data sheets, iPhone 3G and 3GS contain chipsets capable of Rx Diversity, seemingly nullifying AT&T's complaint. It may however be that Apple has not activated the feature or that Apple has and AT&T is spreading misinformation.

The question that arises, however, is that if AT&T is indeed unimpressed by iPhone's baseband, why do they continue to promote and sell iPhone?

Very much so.

A single network can't handle the iPhone.
