AT&T defensively publishes private dropped call data

By Daniel Eran Dilger Published: 05:30 PM EST

While Apple's chief executive Steve Jobs said AT&T wouldn't let him reveal its proprietary data about dropped call statistics for competitive reasons, the mobile provider has revealed some numbers in an effort to defend its network from poor dropped call scores collected by ChangeWave.

ChangeWave published the results of a March survey which indicated AT&T had much higher dropped calls than its US competitors: 4.5 percent compared to 2.8 percent for T-Mobile, 2.4 percent for Sprint, and just 1.5 percent for Verizon Wireless.

That data was collected by a survey of 4,040 smartphone users who were asked to report their own percentage of dropped calls. AT&T's dropped call rate has reportedly inched higher since September 2008, when it was reported to be 3.6 percent, while Verizon's score improved over the same period from a high of 2.7 percent.
