LTE stands for "Long Term Evolution." This acronym refers to the ongoing process of improving wireless technology standards. LTE technology is the next step in increasing broadband speeds to meet the demands of users and the variety of content accessed over mobile networks.
What is 4G?
4G is a wireless technology term meaning "Fourth Generation." 4G follows 3G as the latest addition to AT&T's mobile broadband network. When combined with enhanced backhaul, 4G means faster speeds, where data transfers take less time to complete.
What about HSPA+?
AT&T recently upgraded the software of its nationwide mobile broadband network to HSPA+. HSPA stands for "High Speed Packet Access." HSPA+ provides extended and improved network speeds. When HSPA+ is combined with enhanced backhaul, already fast mobile broadband network delivers even faster 4G speeds.
Ok...now what is backhaul?
Backhaul is one of the major pieces of a telecommunications network. Think of it as the limbs connecting AT&T's cell towers with AT&T's world-class backbone network that provides access to the Internet.
How fast is it?
Our 4G strategy, including HSPA+ with enhanced backhaul and LTE, delivers super fast broadband speeds. 4G HSPA+ with enhanced backhaul delivers speeds up to 4X faster than AT&T's already fast mobile broadband network.
When do I get it?
We rapidly expanded 4G LTE coverage to cover 70 million people and 15 markets by the end of 2011. That coverage will continue to expand in the next few year and is planned to be largely complete by the end of 2013.
