White Spaces Spectrum around the Globe - Microsoft

5. Why Spectrum Sharing is important
Page 5
• 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

19. TVWS – an opportunity to bring a wide range of benefits to the
public and to UK plc through increased bandwidth and range
- 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
“Rural broadband speeds
less than half those in
cities and towns”

31. Mawingu White Spaces Project in Kenya
• 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
• Focused on “off-the-grid” and “off-the-net” regions
• Will enable e-government, distance learning, agricultural
extension, and financial transactions

The South African regulator, ICASA is exploring regulatory opportunity for
TV White Spaces
March 25th 2013 launched trial in Cape Town in partnership with the
Tertiary Education Network, the Wireless Access Provider Association, eSchool Network, and Google

34. Goal is to demonstrate that TVWS can co-exist with licensed spectrum and
create economic opportunity
•
•
10 channels available in Cape
Town
•
2 Mbps per school over 10km
•
Use Google’s spectrum database
to provide available channels for
wireless broadband
•
Offer wireless broadband over
TVWS to 10 schools in the
western cape

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.
