Long Term Evolution (LTE) is the next generation of mobile broadband technology that provides higher data rates and network throughput compared to 3G. LTE networks use OFDM and SC-FDMA for downlink and uplink, respectively, along with MIMO and an all-IP architecture to improve performance. The network elements include eNBs, SGWs, PDN GWs and MMEs. For operators, LTE provides an opportunity to increase ARPU through new applications and services while decreasing CCPU through an all-IP infrastructure. Mass deployment of LTE is expected to begin around 2012, with LTE Advanced enabling data rates up to 1 Gbps.

Introduction Welcome to the world of LTE!
LTE is the next generation of Mobile broadband technologyData rates of 100 MbpsIt is the next level after UMTS 3G technologyWorks with IP!What is LTE?
AdvantagesProvides low latencyHigher network throughputIncreased data transfer speedMore cost effectivenessImprovements over 3G network
LTE v/s Other technologies2G to 4G Evolution and data download rates
Technical ArchitectureWhat is an LTE Network made up of?
LTE TechnologiesOFDM (Orthogonal Frequency Division Multiplexing) for downlinkSC-FDMA (Single Carrier – Frequency Division Multiple Access) for uplinkMIMO (Multiple Input Multiple Output)SAE (System Architecture Evolution)
LTE Architecture Source: Ericsson (2009)
LTE Network ElementsEvolved Node B (eNB)Supports air interfaceProvides radio resource management functionsServing Gateway (SGW)Provides MobilityResponsible for Routing and Forwarding
LTE Network Elements (Continued)Packet Data Network Gateway (PDN GW)Provides connectivity to InternetProvides QoS and mobility between 3G and non-3G networksMobility Management Entity (MME)Manages mobility and provides securityOperates in control plane and provides authentication
Business Case for LTEWhat is the LTE market opportunity and implications for the broaderecosystem, including equipment providers, operators, and devicemanufacturers?
What are the revenue incentives and investment implications for operators who adopt LTE?
