科技前沿:AT&T:iPhone沒有問題

AT&T: What iPhone problem?
In his keynote address at the CTIA's (Cellular Telephone Industries Association) big fall meeting in San Diego Thursday, AT&T's (T) chief technology officer John Donovan denied that Apple's (AAPL) iPhone is the reason so many of customers are complaining about his networks sluggish performance.

"I'm well aware of what's being said in the press, in blogs, and on Twitter," he said. "The iPhone has certainly played a role. But it's not the only device driving growth. We have a lot of people going from basic feature phones to quick-messaging devices and other smartphones, which is driving data usage." (link)

But his words were belied by a graphic he flashed briefly on the screen. We've dug up the source — a white paper published by Rysavy Research in September — and annotated it with a couple iPhone release dates.

The chart (displayed full-size below the fold) shows an 18-fold increase in data traffic during a 28-month period when voice traffic grew only two-fold.

If there were feature phones and quick-messaging devices released at the inflection points corresponding to the arrival of the original iPhone (June 29, 2007) and iPhone 3G (July 11, 2008), we must have missed them.

在週四於聖地亞哥舉行的移動電話工業協會（Cellular Telephone Industries Association, CTIA）秋季大會上，美國電話電報公司（AT&T）首席技術官約翰•多諾萬（John Donovan）在其主題演說中表示，蘋果公司（Apple）的iPhone並非衆多客戶抱怨該公司網絡反應緩慢的原因。

多諾萬說道：“我很清楚媒體、博客和Twitter上的說法。iPhone肯定起了作用。但它並非唯一一款推動增長的設備。很多基本功能手機的用戶換用了能快速收發信息的設備以及其他智能手機，這也推動了數據使用。”

但他在屏幕上閃過的一幅圖表與上述說法相牴觸。我們找到了該圖表的來源——Rysavy Research在9月發表的白皮書——並在圖中附註了兩個iPhone發佈日期。

該圖表（全尺寸顯示如下）表明，語音流量在28個月中僅增長了一倍，而同期數據流量增長了17倍。

假如在第一款iPhone（2007年6月29日）和iPhone 3G（2008年7月11日）上市時間所對應的拐點上，發佈了功能手機和快速收發短信的設備，那麼肯定是我們沒發現。
