Broadband/Mobile Broadband

the 4th Utility

Blurring boundaries and convergence of telecommunication, information, broadcasting, media and publishing technologies

Services grow in multiplicity, diversity and richness of content

More powerful and enabled devices - Changes on the shape, size, capability and price

Hyper Connectivity- mobile Internet with extreme mobility, ubiquity, personalization, adaptation, video addiction and surprising applications as yet unimagined

Ubiquitous ultra broadband high quality and affordable communications essential to the functioning of modern life & society

MBB Communication & Service Outlook

+

Telecommunication at the heart of several industries

Transport, Utility, Education, Health & Commerce 4

High capacity pipes with intelligent plumbing that could incorporate sophisticated resource control capability

Growing Population

Hyper Connectivity

Limited Resources

Hundred-fold increase in network flow brought by mass terminals

and mass digital content and hyper connectivity -> thousand-fold increase in traffic flow on mobile networks

Mobile data traffic is doubling every year BUT capacity doubles every 10 years

Spectrum the blood line of mobile communication, finite resource, scarce & expensive

New network topologies, frequency reuse and deployment strategy key to keep up with exponential increase of traffic with limited spectrum availability

Communication network to improve in intelligence, flexibility, automation, resilience, efficiency, speed, security, privacy, latency YET lower delivery cost per bit/per sub/per km2

Technology & Standards Evolution Towards 5G

Cellular standards are quick to arrive and slow to leave

8 to 10 years between major new standards

Average of 20 years from std intro to peak volume

4G ramp begins around 2011

“LTE now fastest growing mobile tech ever in rollout terms” - GSA

Next generation global standard around 2020

New Air Interface

Higher capacity, better quality, easier operation, lower cost 8

The LTE air interface designed for wide area deployment High UL and DL transmit power difference Different modulation scheme for UL and DL Physical channel structure differ significantly between UL & DL

Shorter round trip delay for the future system RTT an order of 0.1-1 ms In line with higher data rate, fast signalling and feedbacks User plan latency: Frame structure, control signal timing, HARQ

FDD best suited for mainly symmetric traffic (voice), while TDD best suited

for bursty, asymmetric traffic (Internet) AND less complex and less costly (Reuse of sources , no need for duplexer) more flexible than FDD (dynamic reconfiguration of bandwidth) better for massive MIMO (easier and more robust channel estimation) The FDD offers better range (concentrated power per MHz) – BUT FDD

HW more lossy , FDD and TDD similar throughput , similar energy efficacy

The Need For A New Air Interface

A new air interface designed for small cells, suitable for asymmetric service and current challenging spectrum situation

5G Characteristics

New Air interface will be a key enabler for 5G

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 at least ~ 15 - 20 x capacity (2013-2020)

UK Traffic Prediction - 2020

5G will need to be designed not for 2020 but for 2025-2030 capacity !
