AT&T and T-Mobile both announced on Tuesday that they have upgraded their 3G networks with technology enabling faster speeds. Specifically, the carriers have both deployed
HSPA 7.2 technology at their cell sites across the United States. That technology will improve consistency in accessing data sessions, AT&T said, as well as increase network efficiency. Faster speeds will come as AT&T increases the number of high-speed backhaul connections to its cell sites, primarily with fiber-optic connections, over the course of this year and next.
