Shared Spectrum Radios
• In 2000 – FCC proposed that to make more
efficient use of radio spectrum it should be
leased out on basis of :
Space, Frequency, Time, and Power
77
August 2013
• In May 2004, the FCC issued a NPRM (Notice
of Proposed Rulemaking), explaining that its
goals as more efficient use of TV spectrum to
enable new and innovative devices and
services to deliver significant benefit to the
public

Shared Spectrum Radios
• VHF and UHF (TV White Space) are the first to
be in a Dynamically Shared Spectrum. Next
up is 4.9GHz
• PCAST, Presidents Council on Science and
Technology recommended that 1GHz of
spectrum to be freed up using Shared
Spectrum

What White Space Can Do:
TV White Space
• Using TV channels, RuralConnect reaches around mountains ,“through” trees and over water
• 900 MHz competing radios do not propagate through the same geography
• Lower frequencies (TV white spaces) have better propagation for better coverage

The Competitive Hurdle – FCC Requirements
FCC 2008 Shared Spectrum Order:
“All unlicensed TV band devices will be
required to limit their out-of-band
emissions in the first adjacent channel to
a level 55 dB below the power level in the
channel they occupy, as measured in a
100 kHz bandwidth.”
FCC 2010 Shared Spectrum Order:
“We recognize the petitioners’ argument
that tighter emission limits could result in
higher
equipment costs.”
Carlson delivered lower cost radio.
Carlson Solved the FCC Out-of-Band Higher Cost Emission Limits

Applications:
• Ubiquitous Network Access
– Deliver connectivity to patrol cars regardless of location.
• Mobile command
– Effective NLOS Mobile Command backhaul
• Resilient Networks
– TVWS can provide the middle NLOS needed to recover
quickly from a disaster.

Ubiquitous Network Access
Use Carlson’s Rural Connect White Space radio as middle mile backbone to extend
Wi-Fi networks to remote and hard to reach areas
Carlson Wireless worked with the Yurok Tribal Government to trial
such a system….
