  • 1. 5G Research Point of View Base Station Conference 2013 Oct 1st 2013, London Dr Shahram G Niri General Manager, 5GIC (5G Innovation Centre) CCSR, University of Surrey

2. Disclaimer: The views and opinions expressed in this presentation are those of the author / presenter and do not necessarily reflect the official position of the CCSR or 5GIC. 3. Introduction to CCSR & 5GIC CCSR: Centre for Communication Systems Research Established 15 years ago, a leading international communications research centre based at the University of Surrey Europes largest academic research group in mobile communications technology Over 160 research active personnel and research income of over 100m to date 3 Photo for illustration purpose only 5GIC: 5G Innovation Center A successful funding bid made by the University of Surrey to the UK Research Partnership Investment Fund (UKRPIF) Supported by additional contributions from a consortium of enthusiastic and forwarding-thinking operators, infrastructure and solution providers (Founding Members) Will provide research and business engagement opportunities for multinational companies and SME 4. Broadband/Mobile Broadband the 4th Utility Blurring boundaries and convergence of telecommunication, information, broadcasting, media and publishing technologies Services grow in diversity and richness of content - personalization, adaptation and video addiction Hyper Connectivity- More powerful and enabled devices connected - Changes on the shape, size, capability and price Ubiquitous ultra broadband high quality and affordable communications (internet on the move) essential to the functioning of modern life & society Spectrum the blood line of mobile communication, finite resource, scarce & expensive Sustainability of mobile broadband business, ever increasing traffic, high TCO and flattening ARPU Mobile Broadband Outlook Telecommunication at the heart of several industries Transport, Utility, Education, Health & Commerce 4 + 5. Why 5G Growing Population Hyper Connectivity Limited Resources 5G Spectral Efficiency Spectrum Base Station Density Advanced Technologies X X Higher Capacity Green Technology Cost Efficiency Area Spectral Efficiency 5 Communication network to improve in intelligence, efficiency , flexibility, automation, resilience, speed, latency, security, privacy, Policies , delivery cost and business models Quality of Experience 6. Modest increase in number of devices and usage Population density: Case F: UK mean Case D: UK Peak Case C: Office Case A: Inner London business Traffic growth: ~70% CAGR In 2020 depending on the environment traffic per km2 (1.5 to 60 Gb/s/km2) UK needs ~ 15 - 20 x capacity (2013-2020) If traffic doubles every year then up to 4000 time traffic (2013-2025) UK Traffic Prediction - 2020 5G will need to be designed not for 2020 but for 2030 capacity ! 0.00 10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 2012 2013 2014 2015 2016 2017 2018 2019 2020 Gb/s/km2 Traffic growth for cases A-F Traffic - Case A Traffic - Case C Traffic - Case D Traffic - Case F 0.00 10.00 20.00 30.00 40.00 50.00 60.00 2012 2013 2014 2015 2016 2017 2018 2019 2020 Gb/s/km2 Traffic growth for cases A-F (with WiFi off-load) Traffic - Case A Traffic - Case C Traffic - Case D Traffic - Case F 6 7. New air interface Spectrum & radio frequency, millimetre wave New NW architecture Intelligent & adaptive network enough data rate to give Infinite capacity perception for the user Quality of Experience Device 2 device Rethinking spectrum allocation, Spectrum sharing, reframing Licensed &unlicensed operation Integrated NW & services (Mobile+ Broadcast/Multicast) Lowering TCO (cost per bit / km2) Increasing life time of the products (delivering technology through SW) Network sharing Utility type operation 5G Challenges & Changes 7 In addition to technology we need revisit some of the fundamental aspects of the telecom policies and business models 8. 1980S 1990s 2000s 2010s 2020s 1G Voice Digital Data/PS Full IP Analogue 4G (LTE) 2010 Architecture Efficiency 300 Mb/s 5G 2020 (?)
