AT&T Mobile Investment

AT&T announced that it will invest $19 billion to build out its mobile network in 2010 to keep up with growing demand for its Iphone and other 3g devices and phones.

Specifically, AT&T will add 2,000 new cell sites and upgrade existing cell sites with three times more fiber links than it had in 2009. This will increase capacity for the network that connects the cell towers to AT&T’s main network. The backbone portion of the network is a critical component to AT&T’s network; with these upgrades in place – it will help AT&T to easily upgrade in the future to 4G wireless technology.
