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

Wireless evolution 1990–2011

Performance targets for LTE-Advanced and IMT-Advanced

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

Carrier aggregation LTE-Advanced maximum bandwidth in contiguous deployment

Carrier aggregation LTE-Advanced non-contiguous spectrum deployment

Improved MIMO schemes

Coordinated multiple point transmission and reception

Relaying

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

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

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

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

Conclusion
