This document provides an overview of LTE architecture and interfaces. It begins with a brief history of 3GPP and IEEE wireless evolutions leading to LTE. It then discusses the key drivers for LTE including higher data rates and lower latency. The document outlines LTE's technical capabilities such as peak data rates, duplexing methods, and modulation schemes. It also summarizes the LTE system architecture including elements such as the Evolved Packet Core and Evolved UTRAN. Finally, it describes various interfaces within the LTE network architecture including between the EPC and other network elements.
