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

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
