Welcome to the world of LTE!

What is LTE? LTE is the next generation of Mobile broadbandtechnology Data rates of 100 Mbps It is the next level after UMTS 3G technology Works with IP!

Advantages Provides low latency Higher network throughput Increased data transfer speed More cost effectiveness Improvements over 3G network

LTE v/s Other technologies 2G (14.4 Kbps) 2.5G (384 Kbps) 3G (14.4 Mbps) LTE (115 Mbps) 4G (1 Gbps) 2G to 4G Evolution and data download rates

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

What is the LTE market opportunity and implications for the broader ecosystem, including equipment providers, operators, and device manufacturers? What are the revenue incentives and investment implications for operators who adopt LTE?

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
