After the beating AT&T took last year for their inability to handle the wireless bandwidth demands of its customers despite skyrocketing revenues -- AT&T would obviously like to start 2010 off on a better foot. Speaking to the Wall Street Journal at CES, AT&T’s chief marketing officer David Christopher says AT&T is doing everything in its power to improve the network. "We are expanding daily," says Christopher. "It's job one and priority one to make the best network possible,” he says. AT&T of course took a particularly heavy beating late last year for seemingly complaining about people wanting to use the product they're selling, a criticism Christopher's more than aware of while talking to the Journal:Of course AT&T needs to get used to it, because the heavy user of today is the everyday user of tomorrow. Other AT&T execs at CES, like AT&T CTO John Donovan are repeating AT&T's already-stated 2009 accomplishments, including upgraded software allowing 7.2 Mbps speeds, 2,000 new cell sites, 100,000 new backhaul links, and double the number of fiber-served cell sites.
