AT&T CTO: We Know What's Best for You
Late in his speech, he told the crowd that he wasn't ignoring the capacity issue and was well aware of it. "I've read the blogs," he told the assembled throng in the auditorium.
"I don’t plan our networks based on blogs, I plan it based on the needs of our wireless customers -- and no one knows more about the needs of our wireless customers than AT&T."
The CTO gave a wide-ranging speech that dealt with the transition of wireless from a voice-centric medium to one that is becoming much, much more packet-focused. "Data growth is outpacing subscriber growth" on AT&T's network, he said.
Data is much less predictable than voice traffic is, being much more "bursty," with massive traffic flows up and down that can dwindle to nothing quickly, as opposed to the steady flow of voice.
"We no longer have the luxury of predicting where and when we might see [traffic] growth."
This means that, while Donovan stressed that "customers demand openess," he also pointed out the carrier needs to maintain control: "We have to be able to manage our networks so that everyone gets a good experience."
