4 Mobile subscriptions Q regional

5 5.6 Billion smartphone Subscriptions end 2019

6 Traffic Trend In Mobile systems Mobile traffic uptake Summary of trends More subscribers More subscribers More smartphones More smartphones More traffic

7 7 5G use cases All rights reserved Extremely Fast Massive machine Communication WORKS IN A CROWD SUPER REAL-TIME AND RELIABLE

8 5G Key Challenges Massive growth in Traffic Volume Massive growth in Connected Devices Wide range of Requirements & Characteristics >1000x speed latency Affordable and sustainable

9 5G Key Challenges Massive growth in Traffic Volume Massive growth in Connected Devices Wide range of Requirements & Characteristics It is not only about Bigger and better Mobile broadband speed latency Affordable and sustainable

11 Data rates Higher rata rates has been the flying flag for each technology step! 3G HSPA LTE IMT/LTE Advanced 2 Mbps (indoor) 384 kbps (outdoor) 14 Mbps 100 Mbps 1 Gbps (nomadic) 100 Mbps (mobile)? In the future 10 Gbps in specific scenarios 100 Mbps generally available in urban/suburban scenarios High-quality (Mbps) connectivity essentially everywhere

12 Latency / reliability LTE radio-interface latency sufficient in most cases Very low latency may be required by some new applications Traffic safety/control Smart grid Industrial application Tactile Internet Target for the future Possibility for sub-ms latency with very high reliability

13 Traffic capacity Area spectrum efficiency Spectrum efficiency [Mbps/MHz/site] Available spectrum [MHz] Traffic capacity [Mbps/km 2 ] = Available Network density spectrum Spectrum efficiency Network density [sites/km 2 ] More spectrum extending into higher bands including mmw band More dense networks including more extensive antenna configurations Smart cooperation between network nodes

14 Enhanced spectrum efficiency Multi-antenna transmission/reception Multi-site transmission/reception Multi-layer coordination Coordination Interference suppression Full duplex, network coding,

15 More spectrum Up to 2020 Extended spectrum availability up to 6.5 GHz 300 MHz 3 GHz 30 GHz 300 GHz

16 More spectrum Beyond 2020 Extension beyond 10 GHz 300 MHz 3 GHz 30 GHz 300 GHz Large amount of spectrum available Further massive increase in traffic capacity Potential for very large bandwidths Enabler of extreme data rates Small wave length Enabler for massive antenna solutions

17 Future Wireless access In the networked society Multi-hop communication Device-to-device communication and cooperative devices Ultra-dense deployments Ultra-reliable communication Machine communication Inter-vehicular / vehicular-to-road communication Capillary network 300 MHz 3 GHz 30 GHz 300 GHz
