The road to 5G 2
5G will cover new use cases and requirements BroadBand access everywhere Seamless experience of connectivity anytime, • +50Mbps everywhere anywhere, on any access technology BB access in dense areas Video services, possibly empowered by 3D and • Up to 1 Gbps Augmented Reality High user mobility High user mobility on trains, while still enjoying HD movie • Speed up to 500Km/h or work in a videoconference 3
Use cases and requirements Massive IoT Ultra low power, integrated sensors, e. g. wearable Connection • density: to measure various heart rate or blood pressure, … 200.000 /km2 Extreme realtime communications Real-time sensing, data delivery, big data intelligence • < 1ms latency and real-time actuation to enable Tactile Internet Emergency & Safety Public Protection and Disaster Relief e.g. especially for • Resilience & communication among authorities and citizens High Availability 4
Use cases and requirements Ultra-reliable communications < 1ms Monitoring patients & fast medical treatment. • latency Ultra High Vehicles realize critical situations fast, react • Availability accordingly and alert other cars … Broadcast like services One-to-Many Information distributions in areas such as arenas, • transmission event locations, city centers, city metros capability 5
Business Models The Operators’ value proposition may leverage on Operator offer enriched by new / relevant business models – particularly those Partner (retail) Partner Partner offer enriched by related to new services (retail and wholesale) service Operator (wholesale) provider XaaS: IaaS, NaaS, PaaS (wholesale) Asset Network sharing provider (cost savings) Basic connectivity Connectivity Enhanced provider 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 Air interface Spectrum 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 lifecycles: from early studies to standard Is it too early to work on 5G? • Standardization usually starts 4-5 2G 2G years before the first 5000 Mobile connections (in millions) commercial launch of a new generation 3500 3G 3G • R&D activity usually starts 2-3 years before 2500 proposals come to 4G 4G standards… TIM SEP • Major technology shift 5G roughly once every 10 years. 1985 1990 1995 2000 2005 2010 2015 2020 • Approximately 20 year- cycle from launch to Standardization phase Deployment phase peak penetration 10
3GPP: timeline driven by ITU-R IMT-2020 WRC19 WRC15 mmWaves 700 MHz Submission ITU-R Specs Evaluation Requirements IMT-2020 2015 2016 2017 2018 2019 2020 Pre-5G activity in RAN (e.g. Initial 3GPP massive MIMO) Final 3GPP submission to ITU 3GPP submission to ITU Early 5G RAT Release 13 (e.g. 60 GHz radio, LTE evo) 3GPP Release 14 3GPP Release 15 Requirements Start of activities on Architecture Approved Study 5G Radio access Item “SMARTER” Spectrum auctions 11
3GPP: SMARTER Study Item New ew Services vices and Mark rkets ts Techn hnolo ology gy Enable lers Objective ectives: 5G high-level use cases and related potential requirements. Time Frame: April ’15 - March ’16 - More than 40 Telco lco companies worldwide (including Telecom Italia) Which services from Low latency Handover from 5G to earlier generation? 2G/3G? Connectivity for drones Wide area sensors Key Issues Lifeline USIM vs softSIM? communication CS Fallback for 5G Industrial control Programmable & IMS voice? flexible network 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
