Notes from the Broadband Plan Related to CR

James Neel 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 its not my original wording. If its not CR
and / or not related to CRWG projects, I might of
ignored it. Doesnt mean thats not important.
Pulled together in a few hours, so things are
probably missing. Dont treat this as an
authoritative publication. Refer to the plan
itself instead.
Email me if you think I mis-summarized or missed
something important james.neel_at_crtwireless.com

Overview of Key CR-Things I Caught in a Skimming

• TVWS
• Move expeditiously to complete
• High power fixed rural
• TV-gt 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 RD
• Easier experimental licensing

• Spectrum Monitoring
• Create a dashboard
• Augment with utilization info
• Release annually
• Opportunistic Use
• Encourage
• lt 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

4
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 S-Band
• 2.4 Big LEO suitable for terrestrial

5
Spectrum for Opportunistic Use

• 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

• 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

6
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.

7
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-gtMobile 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, market-based 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 doesnt 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

9
D-Block

• 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

• The original rules required the D Block licensee
  to enter into a public-private 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.
