Introduction	 Welcome to the world of LTE!
LTE is the next generation of Mobile broadband technology Data rates of 100 Mbps It is the next level after UMTS 3G technology Works with IP! What is LTE?
Advantages Provides low latency Higher network throughput Increased data transfer speed More cost effectiveness Improvements over 3G network
LTE v/s Other technologies 2G to 4G Evolution and data download rates
Technical Architecture What is an LTE Network made up of?
LTE Technologies OFDM (Orthogonal Frequency Division Multiplexing) for downlink SC-FDMA (Single Carrier – Frequency Division Multiple Access) for uplink MIMO (Multiple Input Multiple Output) SAE (System Architecture Evolution)
LTE Architecture 						Source: Ericsson (2009)
LTE Network Elements Evolved Node B (eNB) Supports air interface Provides radio resource management functions Serving Gateway (SGW) Provides Mobility Responsible for Routing and Forwarding
LTE Network Elements (Continued) Packet Data Network Gateway (PDN GW) Provides connectivity to Internet Provides QoS and mobility between 3G and non-3G networks Mobility Management Entity (MME) Manages mobility and provides security Operates in control plane and provides authentication
Business Case for LTE ,[object Object]
What are the revenue incentives and investment implications for operators who adopt LTE?  
Each segment of the ecosystem has a role to play in LTE’s success 			Source: LTE towards mobile broadband – Altman Vilandrie & company (2009)

Conclusion What does the future hold for LTE?
LTE Future and Uses Mass deployment to begin around 2012 Devices which are covered under LTE are – Mobile phones, laptops, cameras, camcorders Assured interoperability with older wireless technologies such as GSM, WCDMA/HSPA, CDMA, TD-SCDMA
LTE Advanced Mobile Communication Standard As a major enhancement of the 3GPP LTE Standard Peak data rates of 1 Gbps to meet IMT Advanced standards for 4G Ability to leverage advanced topology heterogenous networks such as Picocells and Femtocells Improves capacity and coverage and provides large bandwidth upto 100 MHz of spectrum
Conclusion	 We discussed the topics – What is LTE? Architecture of LTE Networks Market growth and evolution of LTE Future of LTE and LTE Advanced
Thank You! We’d like to answer any questions that you have…
