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
