  1. LTE-Advanced: The Path towards Gigabit/s in Wireless Mobile Communication Prepared byOleg Getmanchuk Submitted to Prof. Dr. Eduard Heindl

  2. Agenda • Introduction • Performance targets for LTE-Advanced • LTE-Advanced technology components • Outlook • Conclusion

  3. Wireless evolution 1990–2011

  4. Performance targets for LTE-Advanced and IMT-Advanced

  5. LTE-Advanced technology components • Carrier aggregation • Improved MIMO schemes • Coordinated multiple point transmission and reception • Relaying • Local area optimization features

  6. Carrier aggregation • LTE-Advanced maximum bandwidth in contiguous deployment

  7. Carrier aggregation • LTE-Advanced non-contiguous spectrum deployment

  8. Improved MIMO schemes

  9. Coordinated multiple point transmission and reception

  10. Relaying

  11. Local area optimization features • Support for heterogeneous networks • LTE self-optimizing networks

  12. Gigabit/s is real • Ericsson - 900+ Mbps • 60 MHz of aggregated bandwidth • Ericsson's commercial base station RBS 6000 • Nokia Siemens Networks - 1.4 Gbps • 100 MHz of aggregated bandwidth • NSN’s commercial Flexi Multiradio 10 Base Station

  13. LTE-A – is not revolution, it is evolution Users should not expect 1 Gbps speeds on their phones next year • Operators do not have 100 MHz of spectrum • No way to use 8 antennas in UE devices

  14. Where to use • Cars or Trains • DSL in rural areas with LTE-Advanced • Improve efficiency wireless connections • Decrease of costs

  15. Conclusion

  16. Thank you!
