GRUPPO TELECOM ITALIA 5G: from analysis to action Luigi Licciardi
The road to 5G 2
5G will cover new use cases and requirements BroadBand access everywhere +50Mbps everywhere Seamless experience of connectivity anytime, anywhere, on any access technology Video services, possibly empowered by 3D and Augmented Reality Up to 1 Gbps BB access in dense areas High user mobility Speed up to 500Km/h High user mobility on trains, while still enjoying HD movie or work in a videoconference 3
Use cases and requirements Massive IoT Ultra low power, Connection integrated sensors, e. g. wearable to measure various heart rate or blood pressure, Real-time sensing, data delivery, big data intelligence and real-time actuation to enable Tactile Internet Emergency & Safety density: 200.000 /km2 < 1ms latency Extreme realtime communications Public Protection and Disaster Relief e.g. especially for Resilience & communication among High authorities and citizens Availability 4
Use cases and requirements Ultra-reliable communications Monitoring patients & fast medical treatment. Ultra High Availability Vehicles realize critical situations fast, react accordingly and alert other cars < 1ms latency Broadcast like services One-to-Many transmission capability Information distributions in areas such as arenas, event locations, city centers, city metros 5
Business Models The Operators value proposition may leverage on new / relevant business models particularly those related to new services (retail and wholesale) Partner service provider Operator offer enriched by Partner (retail) Partner offer enriched by Operator (wholesale) Asset provider XaaS: IaaS, NaaS, PaaS (wholesale) Network sharing (cost savings) Connectivity provider Basic connectivity Enhanced connectivity 6
What is 5G? An extremely flexible and highly programmable e2e system, application, customer, time and location aware Serving at best high diversity types of communications (Human & Machine) with different performance attributes Natively leveraging NFV technologies: Support on demand composition of network functions and capabilities Enforce required capability/capacity where and when needed Profitably accommodating low- and high-arpu traffic and sustainability thanks to cost saving and new business opportunities Being future-proof and ready to serve even not yet identified use case and radio technologies 7
Key issues to reach 5G Spectrum Air interface Architecture & Operations 8
5G Common composable network Use case driven creation of dedicated networks optimized for specific service scenarios / customers (network slices) Combination of functions available in a catalogue, through the NFV Orchestration Platform Only virtualisation can allow the needed flexiblity and sustainability 9
Mobile connections (in millions) Mobile lifecycles: from early studies to standard Is it too early to work on 5G? 5000 3500 2500 2G 3G 4G 1985 1990 1995 2000 2005 2010 2015 2020 Standardization phase TIM SEP 2G 3G 5G 4G Deployment phase Standardization usually starts 4-5 years before the first commercial launch of a new generation R&D activity usually starts 2-3 years before proposals come to standards Major technology shift roughly once every 10 years. Approximately 20 yearcycle from launch to peak penetration 10
3GPP: timeline driven by ITU-R IMT-2020 ITU-R IMT-2020 WRC15 700 MHz Requirements Submission WRC19 mmwaves Evaluation Specs 2015 2016 2017 2018 2019 2020 3GPP Release 13 Pre-5G activity in RAN (e.g. massive MIMO) Early 5G RAT (e.g. 60 GHz radio, LTE evo) Initial 3GPP submission to ITU Final 3GPP submission to ITU 3GPP Release 14 Requirements Approved Study Item SMARTER Architecture Start of activities on 5G Radio access Spectrum auctions 3GPP Release 15 11
3GPP: SMARTER Study Item New Services and Markets Technology Enablers Objectives: 5G high-level use cases and related potential requirements. Time Frame: April 15 - March 16 - More than 40 Telco companies worldwide (including Telecom Italia) Wide area sensors USIM vs softsim? Handover from 5G to 2G/3G? CS Fallback for 5G IMS voice? Which services from earlier generation? Key Issues Programmable & flexible network Low latency Connectivity for drones Lifeline communication Industrial control 12
What else? Softwarisation NFV,SDN, MEC.++ Software will have a key role in the 5G Convergent Network Source IEEE/NTT-DOCOMO 13
What else? Fronthaul and backhaul evolution Mobile Fronthaul: another aspect of Softwarisation C-PRI, ETSI ORI, projects as i-join are defining the radio side and the functional splitting Figures are somehow worrisome ITU-T natural home for the fibre network aspects Collaboration is needed with the radio and mobile architecture groups to assure compatibility and best efficiency of the solutions 14
What else? New Networking Future networking: will IP still satisfy the 5G performance requirements? Requirements on delay and reliability could in some cases be not easy to meet in classic IP networks New concepts as ICN, CCN. Replace? Relay? Integrate? 15
EVOLUTION IN THE RADIO REVOLUTION IN THE CORE 5G: ONE NETWORK FOR A SEAMLESS ENRICHED CUSTOMER EXPERIENCE Shoot for the moon. Even if you miss, you'll land among stars! (Les Brown) 16
