1 Evolution to 5G: An operator's perspective Dr. Ivo Maljevic TELUS team IEEE 5G Summit Nov 2015

2 Cellular Standards Evolution 2? G G G G G Analog systems Large terminals Several systems Voice only Digital systems begin Smaller Phones Several systems Lower power consumption Low data rate services (SMS, ) Emergence of smart phones Dominated by two standards: UMTS and CDMA2000 Data rates up to 42 Mbps Wide range of services Widespread adoption of smartphones Dominated by LTE/LTE-A standard developed by 3GPP Data rates 150+ Mbps Rich services Global 5G standard developed by 3GPP Massive connectivity Data rates 1Gbps+ (fibre like speeds) Very fast service introduction Economy of Scale through standardization

3 Why do we need 5G? Target Use Cases 3 Enhanced Mobile Broadband (embb) 100+ Mbps avg. throughput 10+ Gbps peak throughput Massive Machine Type Communications (mmtc) 10 6 /km 2 connection density Low cost/energy connectivity Ultra-Reliable, Low-Latency Communications (umtc) % service availability 1 10 ms latency Mobile video and gaming Cloud computing and storage High speed connectivity Billions of connected devices Sensor networks IoT / M2M / D2D Tactile Internet Natural disaster relief E-Medicine and Health care 5G will enable diverse services and use cases that cannot be fully addressed by 4G systems

4 4G 5G Target Key Performance Differences Between 4G and 5G Targets 4 Data rate Latency Mobility > 100 Mb/s (avg) > 10,000 Mb/s (peak) ~ 1 ms > 500km/h Spectrum efficiency As much as possible Connection density > 100,000 Avg ~25 Mb/s Peak 150 Mb/s Typically ~50 ms 10 ms for 2-way RAN Functional Up to 350km/h DL: b/s/hz UL: b/s/hz Typically ~2,000 Active users/km 2 Target 5G network capabilities often exceed 4G by a large margin

5 How do we get there?

6 RAN Evolution From Distributed to Virtualized 6 BBU RRU separation Centralization Virtualization BBU RRU BBU RRUs HW Accelerator Virtual Cell Server Central office Central office RRUs Distributed RAN (4G) Centralized RAN (4.5G) Virtualized RAN (5G) Seamless migration from 4G RAN to 5G RAN

7 Network Evolution Through SDN/NFV 7 Different Platforms of Today Internet traffic flows across different service platforms Services operated on specialized Physical and Control infrastructure Converged, Cloud based Platform for 5G Services that previously required dedicated hardware are abstracted into software functions Services will be provisioned and controlled on common infrastructure SDN/NFV will unify ALL SERVICES Fixed and Mobile Convergence

8 The network is responsible for picking most efficient Access to deliver optimal service/user experience 5G Service Delivery 8 Today s Network Service creation in 6+ months Blanket Service Delivery Service-specific access Non-3GPP Access 3GPP Access AAA epdg WAG EPC MSS/MGW HSS/HLR SMSC IMS Policy Server (eg: ANDSF, HS2.0) Customers pick the Access either by device type, app design, or simple steering from network Network Service creation in minutes Data Center Automated E2E Configuration Personalized Service Delivery Agnostic access Non-3GPP Access 3GPP Access Network Wireline Network Access Selection and Network Configuration Home Access Network
