SPECTRUM REFORM NEEDED

• PROBLEMS
• United States General Accounting Office (GAO)
• (now known as the Government Accountability
  Office)
• TELECOMMUNICATIONS (January 2003) Comprehensive
  Review of U.S. Spectrum Management with Broad
  Stakeholder Involvement Is Needed
• TELECOMMUNICATIONS (September 2002) Better
  Coordination and Enhanced Accountability Needed
  to Improve Spectrum Management

• Existing legal and policy framework for
  spectrum management has not kept pace with the
  dramatic changes in technology and spectrum use.

6
FCC SPECTRUM TASK FORCE

• FCC Spectrum Task Force is a roadmap for
  potential spectrum management in the future
  recommendations, not U.S. policy
• Task Force supports unlicensed spectrum overlays
  on existing services
• Task Force supports spectrum commons
  commodity trading
• Task Force supports burden shift from new
  entrants to incumbents
• Market Model of spectrum management must be
  used with caution. Lower entry barriers and
  private sector competition does not support
  public safety missions.

SPECTRUM POLICY INITIATIVE
For Immediate ReleaseOffice of the Press
SecretaryJune 5, 2003
Presidential Memo on Spectrum Policy Memorandum
for the Heads of Executive Departments and
AgenciesSubject Spectrum Policy for the 21st
Century
The Initiative shall undertake a comprehensive
review of spectrum management policies with the

• Meet Critical Spectrum Needs

• No. 13 Policy and Plans Steering Group (PPSG)
• Establish a Policy and Plans Steering Group
  (PPSG) to formalize the coordination process and
  to ensure national security, homeland security,
  public safety, federal transportation
  infrastructure, scientific research, and economic
  opportunity are taken fully into consideration
• No. 14 Policy Coordinating Committee (PCC)
• As needed, the existing White House Policy
  Coordinating Committee (PCC) should be used to
  address spectrum-based radiocommunication issues
  that have not been resolved by the PPSG
• No. 15 Formalize Arrangement With the FCC
  Defense Commissioner
• Work closely with the FCCs Defense Commissioner
  to ensure the concerns of the agencies affected
  by national security, homeland security, public
  safety, and federal transportation infrastructure
  issues are considered fully in the course of NTIA
  and FCC proceedings

Presidential Memo on Spectrum Policy Memorandum
for the Heads of Executive Departments and
AgenciesSubject Spectrum Policy for the 21st
Century
I hereby direct the heads of executive
departments and agencies to implement the
recommendations in the Reports. This order

Spectrum Reform is Progressing

• - RECOMMENDATIONS COMPLETE -
• Spectrum Report 1 Recommendations of the
  Federal Government Task Force
• Spectrum Report 2 Recommendations from State
  and Local Governments and the
  Private Sector
• IMPLEMENTATION ONGOING
• 1. Develop Federal Departments Spectrum
  Strategic Plans
• To NTIA by November 30, 2005
• 2. NTIA will compile a comprehensive Federal
  Government Strategic Spectrum Plan.

• PNT Executive Committee Departments will ensure
  this includes
• regulatory protections for GPS/GNSS

GNSS SPECTRUM ISSUES

• MISSION
• PROTECT SENSITIVE RNSS BANDS FROM ADDITIONAL
  ELECTROMAGNETIC NOISE TO MINIMIZE RADIO
  FREQUENCY INTERFERENCE (RFI)

• 3 Examples to watch out for
• In-Band, Spurious, Out-of-Band Emissions (OOBE)
• Ultra-Wideband (UWB)
• Mobile Satellite Service
• Ancillary Terrestrial Component (MSS ATC)
• GPS Re-radiators

14
WHAT IS ULTRA-WIDEBAND?

• Ultra-Wideband (UWB) is a method of transmitting
  data over very wide bandwidths using a variety of
  modulation techniques (pulses, direct sequence
  spread spectrum).
• UWB is an old technology being taught new
  tricks In the 1920s, Marconis spark-gap radio
  was a form of UWB transmission. Today, UWB is
  being commercialized to access spectrum on an
  unlicensed basis.
• FCC rules constrain UWB emission limits in GNSS
  bands to mitigate radio frequency interference
  (RFI). Testing indicates emission limits should
  not be relaxed further (intentional emissions
  should remain above 3.1GHz).
• UWB responsibly integrated with current and
  planned systems services offers new
  opportunities and benefits. DOT firmly supports
  technological innovation and modernization.

15
WHAT IS MSS ATC?

• MSS ATC
• Mobile Satellite Service Ancillary Terrestrial
  Component
• MSS ATC is building out a ground infrastructure
  to expand the reach of satellite communications
• Injects Out-of-Band Emissions (OOBE) in primary
  GNSS radio band (1559 1610 MHz)
• MSS ATC impacts upon GNSS services is unknown
• High-density network of Mobile Terminals and
  Base Stations
• Mature MSS ATC infrastructure does not yet exist
• FCC regulatory ruling based on assumptions using
  one emitter in 1994

16
International RNSS Spectrum Allocations

• World Radiocommunication Conference (WRC)
• United Nations forum where global spectrum
  allocations are determined every 3-4 years
• Final WRC Acts have Treaty Status
• Stage now set for GPS Modernization
  Coordination with Galileo, other emerging
  constellations
• Future GNSS
• Goal now is to ensure worldwide stability,
  interoperability for a seamless GNSS -- GPS
  remains a free utility
• U.S. opposes forced mandates fully supports
  open, benefit- driven transitions

17
WRC AGENDA ITEM 1.1

• HARMONIZED GPS/GNSS SPECTRUM USAGE
• OVERVIEW The title of this agenda item is
  Deletion of Country Footnotes. In order to
  maintain worldwide radio frequency protections,
  nations must cease allowing interference sources
  in the primary GPS/GNSS band (1559 1610 MHz).
• In about 40 countries, mainly European, Middle
  Eastern, and African, GPS radio spectrum is also
  used for fixed links (microwave links). At
  WRC-2000, these nations agreed to remove these
  fixed links, or use on a non-interfering basis,
  by 2015.
• STATUS
• Nations are beginning to cease use of fixed links
  in the GPS bands.
• U.S. will continue to encourage countries to
  adopt spectrum controls in their respective
  nations to promote safe and reliable GPS/GNSS use
  worldwide.

18
WRC-2003 AGENDA ITEM 1.15

• SPECTRUM FOR GPS GALILEO
• OVERVIEW WRC-2000 allocated radio spectrum to
  support GPS modernization including the new GPS
  L5 as well as planned European Galileo and other
  satellite navigation systems.
• New spectrum for RNSS signals was allocated in
  bands used by long range radars. New spectrum
  for GPS L5 was allocated in the band used by
  DMEs. WRC-2003 reviewed the technical sharing
  arrangements for these allocations.
• STATUS
• 1240 1300 MHZ is Federal Spectrum under NTIA
  Regulation
• Currently Radiolocation / ARNS Primary
• ARNS / RNSS compatibility w/ FAA/DoD Long Range
  RADARS
• U.S. Table of Allocations will be updated after
  Interagency Studies

19
SUMMARY

• DOT firmly supports spectrum innovation and
  creativity, however maintaining a safe and
  effective infrastructure for the traveling public
  is our first priority
• Consensus Recommendations of the Presidents
  Spectrum Policy Initiative will improve Executive
  Branch spectrum management, coordination,
  transparency, and accountability
• U.S. and International spectrum positions and
  regulatory actions must reflect a sensible
  balance between security, public safety, and
  economic growth for GNSS to continue evolving
