  • LONG TERM EVOLUTION(LTE) NIGEL THOMAS S7-B ROLL NO: 23 COLLEGE OF ENGINEERING CHENGANNURSEMINAR-2010
  • CONTENTS 2 INTRODUCTION EVOLUTION OF LTE FEATURES OF LTE TECHONOGIES USED IN LTE LTE / SAE ARCHITECTURE FUTURE SCOPE CONCLUSION REFERENCESSEMINAR-2010
  • INTRODUCTION 3 LTE- LATEST MOBILE BROADBAND TECHNOLOGY 3RD GENERATION PARTNERSHIP PROJECT (3GPP) LTE IS ONLY 3.9G NETWORK DEPLOYED IN DECEMBER 2009 BY TELIASONERA HI-SPEED INTERNET ON THE MOVE!!!SEMINAR-2010
  • EVOLUTION OF LTE 4SEMINAR-2010
  • FEATURES OF LONG TERM EVOLUTION 5 DOWNLINK SPEED : 100 Mbps UPLINK SPEED : 50 Mbps LATENCY : less than 10 ms MOBILITY : upto 360 km/hr CELL SIZE (Range) : upto 100 km BANDWIDTH : 1.4, 3, 5, 10, 15, 20 MHz Co-existent with legacy 3GPP and non-3GPP networks Flat , All–IP Architecture Low CAPEX and OPEXSEMINAR-2010
  • TECHNOLOGIES USED IN LTE 6OFDMA–Orthogonal Frequency Division Multiple AccessSEMINAR-2010
  • OFDMA contd… 7Features of OFDMA Robust to narrow band co-channel interference Helps in QoS and better system spectral efficiency Modulation Schemes: QPSK, 16QAM, 64QAMAdvantages of OFDMA Multi-user Diversity: allows different users to transmit over different portions of the spectrum Efficient use of spectrum Receiver Simplicity- only FFT processor requiredDrawback of OFDMAHigh Peak to Average Power Ratio(PAPR)SEMINAR-2010
  • SC-FDMA (Single Carrier FDMA) 8 SC-FDMA is DFT-Spread OFDMA scheme. It has low Peak to Average Power Ratio (PAPR), hence used as up-link access scheme. Helps in increasing cell size. Modulation Schemes: QPSK, 16QAMTransmitter and ReceiverStructure of SC-FDMASEMINAR-2010
  • MIMO (Multiple Input Multiple Output) Antenna 9Aims:• To improve SNR• To Share SNRTypes of Transmission:• Spatial Multiplexing• Transmit Diversity• Closed Loop- Linear pre-coding and Rank AdaptationBenefits: Increased Capacity,Coverage and Cell throughputSEMINAR-2010

  • FUTURE SCOPE 12 LTE Advanced = 4G Global standard of Communication Inter-Appliance communication i.e.communication between electronicappliances. Voice + Data = 4GSEMINAR-2010
  • CONCLUSION 133GPP Long Term Evolution achieves the lightning speed of access, it’s robustness to interference and the high Quality of Service meeting its performance targets using the following technologies, i.e., OFDMA, SC-FDMA, MIMO Antenna, and the simpler E-UTRAN LTE/SAE Architecture.LTE provides a good foundation in achieving the IMT- Advanced/4G specifications by evolving into the LTE Advanced Technology.SEMINAR-2010
