AT&T Inc. has switched on its high-speed backbone network, which is designed to ferry data traffic across the U.S. four times faster.
AT&T has begun placing traffic on its so-called “ultra-long haul” network, which boasts a capacity of 40 gigabits per second, meaning consumers will be able to download large files quicker and more easily stream online videos to their computers. Carriers have been upgrading the backbone network — the underlying pipes needed to move data across extremely long distances — to meet the increasing demand in bandwidth-intensive programs and videos.
