  1. 1. Long Term Evolution (LTE)<br />By –<br />AbhijitKaul<br />Nitin Khanna<br />SahanaMallya<br />VaibhavMalik<br />
  2. 2. Topics<br />Introduction by NitinKhanna<br />Technical Architecture by VaibhavMalik<br />Business Case by AbhijitKaul<br />Conclusion by SahanaMallya<br />
  3. 3. Introduction <br />Welcome to the world of LTE!<br />
  4. 4. LTE is the next generation of Mobile broadband technology<br />Data rates of 100 Mbps<br />It is the next level after UMTS 3G technology<br />Works with IP!<br />What is LTE?<br />
  5. 5. Advantages<br />Provides low latency<br />Higher network throughput<br />Increased data transfer speed<br />More cost effectiveness<br />Improvements over 3G network<br />
  6. 6. LTE v/s Other technologies<br />2G to 4G Evolution and data download rates<br />
  7. 7. Technical Architecture<br />What is an LTE Network made up of?<br />
  8. 8. LTE Technologies<br />OFDM (Orthogonal Frequency Division Multiplexing) for downlink<br />SC-FDMA (Single Carrier – Frequency Division Multiple Access) for uplink<br />MIMO (Multiple Input Multiple Output)<br />SAE (System Architecture Evolution)<br />
  9. 9. LTE Architecture<br /> Source: Ericsson (2009)<br />
  10. 10. LTE Network Elements<br />Evolved Node B (eNB)<br />Supports air interface<br />Provides radio resource management functions<br />Serving Gateway (SGW)<br />Provides Mobility<br />Responsible for Routing and Forwarding<br />
  11. 11. LTE Network Elements (Continued)<br />Packet Data Network Gateway (PDN GW)<br />Provides connectivity to Internet<br />Provides QoS and mobility between 3G and non-3G networks<br />Mobility Management Entity (MME)<br />Manages mobility and provides security<br />Operates in control plane and provides authentication<br />
  12. 12. Business Case for LTE<br /><ul><li>What is the LTE market opportunity and implications for the broaderecosystem, including equipment providers, operators, and devicemanufacturers?
  13. 13. What are the revenue incentives and investment implications for operators who adopt LTE? </li></ul> <br />
  14. 14. Each segment of the ecosystem has a role to play in LTE’s success<br /> Source: LTE towards mobile broadband – Altman Vilandrie & company (2009)<br />

Potential Business Impact<br />Potential Impact Rationale <br />ARPU Inc.Value added applications<br /> (Average Revenue per User) Advertising revenues<br /> Broadband device proliferation<br />CCPU Dec. All IP Networks<br /> (Cash Cost per User) Backhaul<br />Migration, multiple networks<br />Customer LifetimeSameMore devices per user<br />Non-contract pricing models<br />SubscribersInc.New applicants tap new segments<br /> Greater BW targets performance <br />CapExDec.Economies of Scale<br /> (Capital Expenditures) All IP-N/w & Spectral Efficiency<br />Multiple networks in transition<br /> Source: LTE towards mobile broadband – Altman Vilandrie & company (2009)<br />
  16. 16. Conclusion<br />What does the future hold for LTE?<br />
  17. 17. LTE Future and Uses<br />Mass deployment to begin around 2012<br />Devices which are covered under LTE are – Mobile phones, laptops, cameras, camcorders<br />Assured interoperability with older wireless technologies such as GSM, WCDMA/HSPA, CDMA, TD-SCDMA<br />
  18. 18. LTE Advanced<br />Mobile Communication Standard<br />As a major enhancement of the 3GPP LTE Standard<br />Peak data rates of 1 Gbps to meet IMT Advanced standards for 4G<br />Ability to leverage advanced topology heterogenous networks such as Picocells and Femtocells<br />Improves capacity and coverage and provides large bandwidth upto 100 MHz of spectrum<br />
  19. 19. Conclusion <br />We discussed the topics –<br />What is LTE?<br />Architecture of LTE Networks<br />Market growth and evolution of LTE<br />Future of LTE and LTE Advanced <br />
