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

• 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

Field trial in Cape Town with local partners

• The South African regulator, ICASA is exploring regulatory opportunity for

TV White Spaces

• ICASA issued a TV White Space license to CSIR Meraka to conduct

technology field trial

• March 25th 2013 launched trial in Cape Town in partnership with the

Tertiary Education Network, the Wireless Access Provider Association, e-

School Network, and Google

Goal is to demonstrate that TVWS can co-exist with licensed spectrum and

create economic opportunity

• Trial license has been issued and

network deployed

• 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

• IP backhaul from local medical

school
