Future Wireless Broadband Access

Thinking Beyond LTE

Wireless Broadband: Where we stand today

Cisco projects an 18-fold increase in mobile data traffic over the next five years.

Video will be by far (70.5%) the dominant traffic profile driving this demand explosion

Wireless Service Providers are moving to tiered service levels & traffic shaping to

manage spectrum resources in response to this growing demand for data connectivity

Urbanization, shift of traffic indoors & need for better use of spectrum is driving small

cell technology, a network-of-networks & a blurring of the once cellular-WiFi divide

Digital immigrants are giving way to the digital natives who are reinventing the media

experience that will challenge even the most aggressive infrastructure investment

Today’s wireless technology & spectrum roadmaps will struggle to keep ahead of

demands & shifting user behavior. New thinking on spectrum & architectures required


The Bandwidth Crunch Challenge More spectrum debate continues but we believe it will only be part of the solution

More spectrum and new thinking is required to meet this challenge

2020 30Mbps x 5477/km2 x 1.70 x 25% 69.8Gbp/s/km2

Assuming state of the art LTE-A** today

In 2016 we may need 317MHz of spectrum

In 2020 we may need more than 5GHz!

InterDigital Communications Research: What We Do

InterDigital has been tackling the bandwidth crunch for generations

InterDigital develops fundamental

wireless technologies that are at

the heart of mobile devices,

networks, & services worldwide. Vision

As a long time contributor to the

wireless industry, we have solved

many of the most critical mobile

challenges for 30+ years

Our technology is used in all 2G,

3G, LTE devices providing support

for new mobile broadband &

richer multimedia experience

We offer our technologies to the

market in IP blocks and full

product solutions and have been

key in high profile OEM offerings

Today’s Challenge is More Complex than Ever

Service Provider Options Today:

Ration resource usage

Invest in new capacity

New revenue innovation

spiraling

capex/opex


And Tomorrow (2020)

Two tech trends will perhaps shape future more than any


The Remarkable Shrinking Cell

It has always been about making the network more efficient and smarter

All driving us to a world of ubiquitous connectivity asset availability

This is unlikely to change anytime soon

Next step: cooperative ultra-dense cell technology

that opportunistically leverages licensed/unlicensed

Cellular controlled Device2Device communications:

Our research shows time is right for this technology

And beyond: Falling device cost & wealth of spectrum

will drive THz move for “indoor & around” applications

And Convergence of Computing/IT & Telecom Tech

Network virtualization enables sharing & efficient leveraging of assets

The cloud is about reducing OPEX/CAPEX, resource sharing flexibility

This HAS happened

IT resource virtualization

Infrastructure sharing

Policy driven architecture

Outsource of operations

NaaS, IaaS, PaaS

This is happening NOW

All IP network to share BW

Silos converged network

DPI & Open API initiatives

Network sharing/outsourcing

Computing


Evolving Norms in Definition of Connectivity Assets

* 200%-300% improvements observed at cell edge

Sharing, flexibility, aggregation is the new normal

The next step up is dynamic, policy driven, real-time

White space is the incubation ground for this emerging tech.

Our research here suggests ~100% gains in key QoE metrics

Intelligent, self organizing, offload is the new normal

The next step up is to push virtualization down to client

Flow segmentation & IP flow mobility key steps on this path

Linear QoE potential but more e2e traffic shaping & control

High powered, multi-core, multi-purpose is new normal

The next step up is to unleash the power in the “crowd”

Bring resources into a controlled virtual access infrastructure

Gains in excess of 50% observed* with little negative impact

And Thinking Beyond 4G: A New Air Interface!? As before it will be complex question of timing, drivers and enablers

19821

2014? 2G 3G 4G Beyond 4G Mostly about Spectral Efficiency Increasingly about General Data support & Spectrum Flexibility

19951 20041

Emergence of digital tech.

Affordable DSP technology

Forward error connection

Feasibility of CDMA (Reuse=1)

Invention of Turbo codes

Advanced receivers

Process node evolution

Invention of MIMO

Natural fit with OFDM

Maturity of SDR Technology

Wideband Digital Transceivers

Spectrum sensing advances

Can we build a B4G business case based on improvements here?

Energy Efficiency

Specialized Data

Spectrum Agility

Likely air interface drivers beyond 4G:

Video is set to be the dominant traffic profile:

Makes sense to optimize protocol design to

most efficiently handle this new requirement?

Energy crunch is just flip side of BW crunch:

Makes sense to improve MAC/PHY/RF design

to minimizes OPEX & build a greener world?

Small cells & sharing driving biggest gains:

Makes sense to discuss new MAC/PHY/RF

tech. to enable dynamic spectrum sharing
