Long Term Evolution (LTE) is one of the choices for next generation broadband wireless networks and is defined by the 3GPP standards as an evolution to a variety of 3G wireless networks, including both UMTS and 1xEV-DO; its high data rates enable a wide range of advanced multimedia applications. This eLearning course offers a quick, high-level overview of LTE radio and Evolved Packet Core (EPC) networks. The key characteristics of the LTE air interface, access network and core network are defined, along with a review of the capabilities of the LTE user equipment (UE). The services expected to be supported on LTE networks are summarized, with special emphasis on voice solutions. Finally, important considerations for deploying LTE networks are laid out, including the ability to interwork with existing 3G networks.
