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 Europe’s largest academic research group in mobile
communications technology Over 160 research active personnel and research income of over
£100m to date

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
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

Communication network to improve in intelligence, efficiency , flexibility, automation, resilience, speed, latency, security,
privacy, Policies , delivery cost and business models
Quality of Experience
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 !

Technology & Standards Evolution
Cellular standards are quick to arrive and slow to leave
8 to 10 years between major new standards
Average of 20 years from std to peak deployment
4G ramp up began around 2011
“LTE now fastest growing mobile tech ever in rollout terms” – GSA
5G is expected to be event faster
Next generation global standard around 2020

Data rate increase
New Air Interface (Small Cells)
New waveforms New duplexing New MAC Higher order modulation Multi-cell cooperation Interference cancelation / utilization Massive MIMO / Distributed MIMO
Radio Frequency
Millimeter wave New licensing regime Licensed & unlicensed band operation Spectrum sharing Indoor-Outdoor operation
Cognitive radio and network Opportunistic & adaptive use of resources Spectrum sensing Automated networks/ Plug & play Lower and smarter use of energy
Mixed Cell & Het-Net management Centralized RAN / Cloud RAN SW Defined Radio (SDR) & Networks (SDN) Separation of data & control planes Integrated NW (Mobile+ broadcast/multicast) Network sharing
High Level Research Challenges For 5G
New NW Architecture
The gap between anticipated traffic & available capacity is significant - We will need to look at every possible technology enhancements
