Originally presented to WinnF CRWG 3/17/10, some wording fixed
Disclaimers
Lots of text and all figures from the plan. When in doubt, if it looks like a sentence,
assume that it’s not my original wording.
If it’s not CR and / or not related to CRWG projects, I might of ignored it. Doesn’t
mean that’s not important.
Pulled together in a few hours, so things are probably missing. Don’t treat this as an
authoritative publication. Refer to the plan itself instead.

Overview of Key CR-Things I Caught in
a Skimming
• TVWS
– Move expeditiously to complete
– High power fixed rural
• TV-> Mobile
– Some TV bands appears to be
going to cellular (impact on
TVWS?)
• At least 120 MHz
– “Voluntary”
• Satellite
– Enhance movement to mix
terrestrial / satellite in Mobile
Satellite Spectrum (MSS).
• D-block public/private still of
interest (pushing LTE)
• Other
– Encourage R&D
– Easier experimental licensing
• Spectrum Monitoring
– Create a “dashboard”
– Augment with utilization info
• Release annually
• Opportunistic Use
– Encourage
– < 10 years new contiguous
nationwide band
– Encourage secondary markets
• Federal Squeeze
– AWS 20 MHz
– Look for more opportunities to
repurpose
– Start charging fees to users of
government spectrum.
Spectrum for Mobile Notes
• 300 MHz in 5 years for mobile
• Biggest chunk from Broadcast TV
• Looks like Hazlett plan (some later)
• Less spectrum for TVWS
Satellite Bands for Ancilliary Terrestrial
•
•
Authorized 2003
No licensee is operating a live commercial ATC network,
– Globalstar, SkyTerra, DBSD, Terrestar authorized to provide ATC services.
•
Gating criteria problem for deployment and partnering
• Various fixes – benchmarks, incentives
• Add a primary “mobile” (terrestrial) allocation to the SBand
• 2.4 Big LEO suitable for terrestrial
Spectrum for Opportunistic Use
• TVWS
– The FCC should move expeditiously
to resolve pending petitions for
reconsideration in the TV white
spaces proceeding
– As the FCC considers other changes
to the TV broadcast spectrum, it
should also evaluate the impact on
the viability of use of TV white
spaces
– Consider higher power fixed
operation in rural areas
– Reconsider border issues for low
power devices
– Does further TV reallocation
impact TVWS?
• Earmarked for cellular
• Maybe not BW, but definitely
channels
• Extend geolocation database
concept to other bands
• Free up new unlicensed
contiguous band in next 10 years
• Allow use in spectrum held by
FCC (sandbox)
• More experimental licensing
• Additionally, the National Science
Foundation, in consultation with
the FCC and NTIA, should fund
wireless research and
development that will advance
the science of spectrum access
CRDB / REM Note
• Second, the FCC should initiate a proceeding that
examines ways to extend the geo-location database
concept, currently being implemented in the TV bands,
to additional spectrum bands that are made available
for access by opportunistic radios.
• In addition, devices that operate under this database
approach may serve effectively as “listening posts” to
measure and report usage of the spectrum back to the
database. These reports could improve the
opportunistic use of the selected frequencies without
causing harmful interference.
Secondary Markets
• To ensure that secondary markets
are functioning effectively, the
FCC should identify and address
barriers to more productive
allocation and use of spectrum
through secondary markets. The
FCC should complete its
assessment of potential barriers
by the end of 2010.
• Thousands of transactions since
allowed in 03-04
– Transfers, partitioning, leases,
disaggregation
• Want to enhance and to support
emerging technologies
• Examine additional positive
incentives
– reducing secondary market
transaction costs like lease filing
costs, and encouraging and
facilitating the use of dynamic
spectrum leasing arrangements that
harness emerging technologies.
• Consider a more systematic set of
incentives, both positive and
negative, to ensure productive use
of spectrum to address broadband
gaps in underserved areas.
TV->Mobile Notes
• Want 120 MHz for economic
reasons
– 700 MHz sold at $1.28 MHz-pop
– Estimate current usage at $0.11$0.15 MHz-pop
• Redo Channel Assignments
– Repacking alone could potentially
free up to 36 megahertz
– Retune TVs antenna directions
• Allow 2+ stations to share a
channel
– Many already broadcasting
multiple streams
• Set rules for auctioning freed
spectrum
– Stations receive share of proceeds
– establish a voluntary, marketbased mechanism to effect a
reallocation, such as the incentive
auctions
– Likely in biggest cities
– New business models enabled by
the DTV Transition: multicasting
and mobile DTV
• If voluntary doesn’t work,
consider other architectures
– Cellular, overlay license, require
sharing, packing, other
• Enhance efficiency
– Charge high power fees, transition
date for low power DTV, trust fund
for public interest media
D-Block
•
•
The original rules required the D
Block licensee to enter into a publicprivate partnership with the PSBL to
build a public safety broadband
network. The absence of meaningful
bidding activity indicated that the
public safety obligations as designed
were not commercially viable. The
approach recommended in Chapter
16 would allow for a voluntary
partnership between public safety
broadband spectrum holders and
commercial partners, including the D
Block licensee(s). Limited technical
requirements on the D Block can help
maximize the number of partners
available to public safety, while also
maximizing the commercial potential
of the spectrum.
•
Nationally standardized air interface
(LTE) for roaming and ease of
implementation of prioritized access
Define compensation plans for public
safety roaming and priority access on
broadband networks
– Required for Block D
•
D Block licensee(s) must develop and
offer devices that operate both on the
D Block and the neighboring public
safety broadband block
– path toward scale production of
components and devices
•
Commercially reasonable buildout
requirements.
– incentives to promote rural / public
safety benefits
