2 Key requirements towards 2020 Support up to 1000 times more traffic Manage up to 10 times more users Enable Gbps peak speeds Reduce latency to milliseconds Improve energy efficiency Make networks selfaware, selfadaptable, and intelligent Deliver safe superior customer experience We cannot predict all the use cases so flexibility is a key requirement 2 Nokia Siemens Networks 2012

3 Key requirements towards 2020, Performance Support up to 1000 times more traffic Manage up to 10 times more users Enable Gbps peak speeds Reduce latency to milliseconds Improve energy efficiency Make networks selfaware, selfadaptable, and intelligent Deliver safe superior customer experience We cannot predict all the use cases so flexibility is a key requirement 3 Nokia Siemens Networks 2012

4 Support of up to 1000 times more capacity in wireless access 10x Performance 10x Spectrum 10x Base stations 1000x Capacity Spectral efficiency [bps/hz/cell] HSPA LTE-A 4x4 +CoMP + interf. cancel. + innov. further Available radio spectrum 2.0 GHz 1.5 GHz 1 GHz 0.5 GHz 0 GHz Unlicensed Licensed Global base station forecast 50 Mill 40 Mill 30 Mill 20 Mill 10 Mill 0 Mill Most of these will be small cells In addition over 500M WiFi APs 4 Nokia Siemens Networks 2012

5 3GPP Release 12 will bring significant performance boost Rel12 Feature Small Cell Enhancement based on Inter-site CA New Carrier Type (NCT) Elevation beamforming / 3D-MIMO Advanced receivers Enhanced SON Benefit Optimized small cell mobility by reducing RAN to CN signaling Improved data rates by using macro and small cells together Efficient use of TDD spectrum Minimized inter-cell interference Lowered BTS energy consumption Significant overhead reduction Significantly enhanced macro cell capacity and coverage Removing interference to increase UL and DL capacity Efficient operation of dense small cell deployments Energy savings in small cell capacity layers 5 Nokia Siemens Networks 2012

6 But we can further optimize a Beyond 4G Local Area Radio System Requirements for B4G Local Area Always connected, 10Gbit/s peak data rate, 1ms RTT Support flexible deployment and new use cases Low cost, low power consumption TDD is an attractive duplexing method Flexible UL/DL duplexing Fluent support of access, self-backhauling and D2D Low cost RF Reciprocity gains for MIMO WSN WSN Component technology evolution is main enabler to allow low TDD latency E.g. fast switching 6 Nokia Siemens Networks 2012

7 Further in the future, millimeter wave band is promising Huge spectrum available at GHz Advantages Can easily meet B4G peak and edge data rates Exploit beamforming gains using massive antenna arrays Access and backhaul can use same radio Development needed in several areas like mm-wave integrated circuits Antenna array architectures mm-wave propagation 7 Nokia Siemens Networks 2012

8 Key requirements towards 2020, Management Support up to 1000 times more traffic Manage up to 10 times more users Enable Gbps peak speeds Reduce latency to milliseconds Improve energy efficiency Make networks selfaware, selfadaptable, and intelligent Deliver safe superior customer experience We cannot predict all the use cases so flexibility is a key requirement 8 Nokia Siemens Networks 2012
