Why Spectrum Sharing is important
• Increase in wireless broadband use driving demand for spectrum
• Legacy spectrum allocations are underutilized and slow to evolve
• Need to balance licensed and unlicensed spectrum availability
• Get more use out of a limited resource by sharing it
• Broad support from regulators and industry leaders
• TV white space is the first and most immediate opportunity

TVWS – an opportunity to bring a wide range of benefits to the
public and to UK plc through increased bandwidth and range
“Rural broadband speeds
less than half those in
cities and towns”
- 13 fold increase from 2012 level
- 66% will be video
- 45% will be off-loaded to fixed
networks
Cisco projections for global
mobile data traffic by 2017
Service providers and
the public need more
unlicensed spectrum
to enable growth. UHF is
best for coverage and
building penetration

Academically-led, Industry-focused
A multi-disciplinary international centre engaging with industry, government and
academic partners to undertake R&D on Dynamic Spectrum Access and related areas
• Led by the University of Strathclyde
• Builds on over 30 years of experience in mobile
communications and signal processing
• Investigating technological and socio-economic
aspects of Dynamic Spectrum Access using White
Spaces
• Led by Indigo, a Kenyan Internet Service Provider (ISP)
• Branded as “Mawingu” or “cloud” in Swahili
• Under a test license from the Communications Commission of Kenya
• Leveraging TV white spaces spectrum, database access, and solar powered base stations to deliver BB access

• Use Google’s spectrum database
to provide available channels for
wireless broadband
• Offer wireless broadband over
TVWS to 10 schools in the
western cape
• IP backhaul from local medical
school

The Industrial Internet could
boost
annual productivity growth
by 1-1.5%
Over the next 20 years it
could raise avg. incomes by
an impressive 25-40%
The Industrial Internet
could add $10-15
trillion to global GDP
over the same
horizon.
What is the opportunity? According to GE = $70 Trillion
