John Donovan (pictured), senior EVP, AT&T technology and network operations reports in AT&T's Innovation Space blog that "Running year-end numbers that show the same result as previous years is typically a sign of stability ..But when the year-end numbers show a doubling of wireless data traffic from 2010 to 2011 – and you’ve seen at least a doubling every year since 2007 – the implications are profound .. Over the past five years, AT&T’s wireless data traffic has grown 20,000%".
"AT&T has invested more than $95 billion in its wireless and wireline networks over the past five years. In 2011, we invested $20 billion in our networks, and completed more than 150,000 wireless network improvements. And we expect to invest about $20 billion again in 2012 with a focus on wireless, including more 4G LTE deployment, the roll-out of distributed antenna systems in key venues across the U.S. and adding even more AT&T Wi-Fi Hot Spots to the nation’s largest Wi-Fi network."
