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

The 5GIC is the world's first dedicated 5G programme and an international hub for telecommunication research and innovation with a unique large scale 5G test-bed for network testing.

Ubiquitous, high quality and affordable communications (essential to the functioning of modern life & society)

Around half of over 3 B devices connected to internet today are via wireless networks

Increasingly the internet is being formed as network of ‘things’, rather than network of computers

Hyper-connectivity of billions of devices nut just P2P but P2D, D2D, M2M makes the Internet-of-Things an ever growing phenomenon

Users are adopting new habits, how they use mobile phones and how they access the internet

More powerful and enabled devices are becoming available and affordable

Services are also growing in multiplicity, diversity and richness of content

End user delight is absolutely essential to the success of telecom industry Broadband the 4th Utility

Quality of Experience

Number of connections and also the volume of data over wireless networks continuously growing at a significant rate

Users more demanding on quality & price

Sustainability of mobile broadband business (ever increasing traffic, higher TCO and flattening ARPU)

3G & 4G both promised improvements in NW capacity, data rate, efficiency, cost and quality

5G will be no exception but the sheer scale of the challenges this time makes 5G research different

5G needs to embrace a significant leap forward in terms of targets

Spectrum: finite resource, scarce & expensive

New air interface Spectrum & radio frequency, millimetre wave New NW architecture, Intelligent & adaptive network

“Perception of infinite capacity for users” Quality of Experience (Latency & Reliability) New services, e.g. Device 2 device

Rethinking spectrum allocation, sharing, reframing Licensed &unlicensed operation Integrated NW & services (Mobile+ Broadcast/Multicast)

Lowering TCO (cost per bit / km2) Greener telecommunications Increasing life time of the products (delivering technology through SW)

Network sharing New revenue models Utility service type operation

Interference cancelation / utilization

Higher Capacity to be delivered by a combination of several techniques AND densification of network

Focus on area spectral efficacy NOT JUST link spectral efficiency

Designed for small Cells (Capacity), extended to coverage

More spectrum (Licensed & unlicensed operation, Spectrum sharing AND other sources)

Sub 1GHz for coverage, sub 6GHz as core spectrum AND mmWave (10-100 GHz) for ultra dense access & backhaul

Better use of resources (Cloud Radio – Baseband)

Designed for Mesh NW, D2D, Self backhauling (devices powerful enough to act as NW nodes)

Super low latency: oFor new services (MTC, gaming, ….) oDistributed control oFaster signaling for higher data rate

Super reliable:

o For new services and applications o Smart transport, e-health, intelligent control o May need a tradeoffs in capacity, coverage and data rate

Greener technology (Energy efficiency)

oCurrent 2% ICT share of CO2 emission is likely to raise oPower consumption doubled in past 5 years oMore power efficient HW & SW, oReducing signaling through intelligent O&M and SON oAlternative energy sources

Lower CTO

Reduced Total Cost of Ownership oFor x1000 do we need to achieve 1/1000

delivery cost per bit? oCost will need to be recalculated as bit/km2 o Saving through energy consumption oSaving through lower cost of operation (plug

& play, self managed NW) oSpectrum and infrastructure sharing oLonger HW life cycle time oNew business models (new revenue models)

3G: Started in 1989, standards in 1999, commercial system in 2003

4G: Started in 2000, standards in 2008, commercial in 2011

5G: Already started, standards in 2017+, commercial readiness in 2020

Cellular standards quick to arrive and slow to leave ~ 10 years between major new standards Average of 20 years from STD to peak deployment

2G in 1990’s, 3G in 2000’s, 4G in 2010’s AND 5G in 2020’s

5G Time Lines

11

Capacity the biggest driver for 5G will not be delivered via one technique but a combination of several techniques

Much denser network and small cells will be a key part of 5G design

NW will need to be designed with future services/application in mind BUT not for particular services

Spectrum remains to be the greatest challenge for telecom industry

Sharing is a must in 5G – spectrum sharing to be enabled both in terms of technology and also business model

Sharing is good for 5G - greater degree of sharing, site, infrastructure, … (new operation and business models)

The shape of NW architecture will need to change – mobile to play a role as NW node (D2D,mesh NW, …)

Telecom industry needs to cope with exponential growth phenomenon!

5G success depends not only on the underlying technologies but also in rethinking business models, policies and economics around radio spectrum regulation
