APT Preliminary Views for WRC (as at APG2007-3)

• Agenda Item 1.3 Primary RLS 9 000-9 200 MHz and
  9 300-9 500 MHz and 200 MHz for EESS and SRS
  above or below 9 500-9 800 MHz
• Bands used internationally for aeronautical
  radionavigation including airborne weather radar,
  precision approach radar, surface movement radar
  and Airport Surface Detection Equipment
• Also used for Govt (radiolocation) Maritime
  (radionavigation) radars

• Aeronautical radionavigation ground-based radars
  critical to airport ops during poor weather.
• Standard mandated aircraft weather radar for
  Regular Passenger Transport (RPT) aircraft in
  many countries.
• Safety of life aspects, careful consideration
  required so that the use and development of the
  radionavigation service is not interfered with or
  constrained.

11
APT Preliminary Views for WRC (as at APG2007-3)

• Agenda Item 1.3 Primary RLS 9 000-9 200 MHz and
  9 300-9 500 MHz and 200 MHz for EESS and SRS
  above or below 9 500-9 800 MHz
• a. Upgrading of radiolocation
• APT Administrations are of the view that the
  upgrading of radiolocation service to primary
  would be supported, subject to agreed ITU-R
  studies indicating that sharing with the
  radionavigation service is possible. These
  studies to be done by ITU-R needs to take into
  account measurement tests. It is also required
  that the radiolocation service operating in the 9
  000-9 200 MHz and 9 300-9 500 MHz bands should
  not cause harmful interference to, nor claim
  protection from, the radionavigation service,
  operating in accordance with the Radio
  Regulations. This could be accomplished by an
  appropriate footnote to protect the aeronautical
  radionavigation and radionavigation systems. One
  Administration is considering if this or another
  method would best achieve its objectives.

APT Preliminary Views for WRC (as at APG2007-3)

• Agenda Item 1.3 Primary RLS 9 000-9 200 MHz and
  9 300-9 500 MHz and 200 MHz for EESS and SRS
  above or below 9 500-9 800 MHz
• b. The extension of EESS and Space Research
  Service by 200 MHz
• APT Members are of the view that they support
  ongoing ITU-R compatibility studies between the
  existing systems operating in the radiolocation
  and radionavigation services in the 9 300 9 500
  MHz band and the spaceborne radar systems
  operating under EESS (active) and SRS (active).
  Any expansion of the EESS (active) and SRS
  (active) allocation beyond the band 9 500-9 800
  MHz should ensure that the incumbent services are
  protected. Should an expansion be granted to the
  EESS (active) and SRS (active) to operate
  spaceborne radar, some APT Administrations
  consider at this time that the lower portion (9
  300-9 500 MHz) are preferable due to the fact
  that the band 9 800-10 000 MHz, fixed systems are
  operating or planned to be operated in some APT
  Administrations. Necessary regulatory text will
  be required to ensure protection to incumbent
  services.

APT Preliminary Views for WRC (as at APG2007-3)

• Agenda Item 1.5 to consider spectrum
  requirements and possible additional spectrum
  allocations for aeronautical telecommand and high
  bit-rate aeronautical telemetry, in accordance
  with Resolution 230 (WRC 03)

• Spectrum required for Unmanned Aerial Vehicles
  (UAV), flight testing of modern aircraft and
  other civil and Govt aerospace platforms
• Studies focusing on short/medium term below 16
  GHz and long term below 30 GHz (technology
  constraints)
• Bands being studied 4 400-4 940 MHz, 5 030-5 150
  MHz, 5 150-5 250 MHz, 5 925-6 700 MHz, 22.5-23.6
  GHz, 24.75-25.5 GHz and 27.0-27.5 GHz

• Agenda Item 1.5 to consider spectrum
  requirements and possible additional spectrum
  allocations for aeronautical telecommand and high
  bit-rate aeronautical telemetry, in accordance
  with Resolution 230 (WRC 03)
• a. APT Administrations support the studies under
  Resolution 230 (WRC03) into the requirements for
  justifiable wideband aeronautical mobile
  telemetry (AMT) and associated telecommand
  spectrum above 3 GHz, and notes that considering
  (d) of this Resolution identifies a need to
  protect existing services.These studies will
  need to take into account
• the bandwidth demand for wideband AMT and
  associated telecommand and
• where appropriate, existing ARNS and FSS
  allocations, including the existing and planned
  usage by each service and
• possible developments under Agenda item 1.6
  (Resolution 414 (WRC03)) in the 5 091-5 150 MHz
  and other aeronautical radionavigation bands
  between 3 and 6 GHz. Any allocation to AMT in an
  ARNS or AM(R)S band should be conditional upon
  the completion of rigorous and conclusive ITU-R
  studies first which demonstrate that sharing will
  not have any implications for the safety of
  operations of affected aviation systems.
• In these studies all bands above 3 GHz should be
  considered under Resolution 230 (WRC-03),
  including possible additional allocations under
  Resolves 3, unless completed ITU-R studies show
  that it is not possible to use those particular
  bands for wideband AMT and associated telecommand.

• Agenda Item 1.5 to consider spectrum
  requirements and possible additional spectrum
  allocations for aeronautical telecommand and high
  bit-rate aeronautical telemetry, in accordance
  with Resolution 230 (WRC 03)
• b. Regarding the resolve 4, APT could support to
  give a priority to the designation of frequency
  bands already allocated to mobile service between
  16 and 30 GHz for wideband aeronautical telemetry
  and associated telecommand on a primary
  basis.Any action in regard to this agenda item
  must take into account the existing services to
  which this frequency band is allocated and fully
  protect them.Appropriate revision/modification
  of footnotes to The Table of Frequency
  Allocations, Article 5 RR, might be required
  (i.e. 5.342, 5.343, 5.348B, 5.394,
  5.395).Frequency band 5 925  6 700 MHzStudy
  the feasibility of co-band sharing of AMT and
  incumbent radio services in the bands

  bands above 6 GHzStudy the feasibility of
  wideband aeronautical telemetry and associated
  telecommand using the bands 22.5-23.6 GHz,
  24.75-25.5 GHz and 27.0-27.5GHz.Support the
  designation of frequency bands already allocated
  to mobile service between 16 and 30 GHz for
  wideband aeronautical telemetry and associated
  telecommand on a primary basis.

• Agenda Item 1.6 to consider additional
  allocations for the aeronautical mobile (R)
  service in parts of the bands between 108 MHz and
  6 GHz, in accordance with Resolution 414 (WRC 03)
  
• VHF congestion (Europe and USA) and new ATM and
  Aeronautical operation control (AOC) requirements
• VHF comms band nearing saturation even with 8.33
  kHz channelling
• ATM increased use of datalinks - air-derived
  data, separation and self-separation of aircraft
• AOC Dispatch, Flight Planning, and other airline
  operational comms
• Airport Wireless and Security Applications
• High integrity WLANs with connected grids of
  distributed sensors - reduce runway incursions,
  increased comms capacity at airports
• secure air-ground radio link with key security
  information in encrypted form to decision-makers
• UAT requires AM(R)S allocation
• UAV telemetry/telecommand links for safety and
  regularity of flight

APT Preliminary Views for WRC (as at APG2007-3)

• Agenda Item 1.6 to consider additional
  allocations for the aeronautical mobile (R)
  service in parts of the bands between 108 MHz and
  6 GHz, in accordance with Resolution 414 (WRC 03)
  
• a. APT Administrations support global allocations
  to the aeronautical mobile (R) service in the
  frequency bands 960-1 024 MHz and 5 091-5 150 MHz
  if shown to meet global CNS/ATM requirements and
  future trends on the basis of compatibility with
  the existing services and it cannot operate in
  existing aeronautical mobile (R) spectrum.
• In the 5 091-5 150 MHz band compatibility will be
  required with FSS Earth-to-space feeder links.
  Some Administrations in APT has operational
  feeder links in this band.
• It is also recognized that there is a need to
  maintain compatibility with services in adjacent
  bands. In particular, any allocation changes in
  the 108-117.975 MHz band must be compatible with
  terrestrial broadcasting systems and place no
  additional constraints on the broadcasting
  service in the band 87-108 MHz.

• Agenda Item 1.6 to consider additional
  allocations for the aeronautical mobile (R)
  service in parts of the bands between 108 MHz and
  6 GHz, in accordance with Resolution 414 (WRC 03)
  
• b. The frequency band 5 000-5 030 MHz is
  allocated to RNSS and is either currently used or
  is to be used by some systems. If this band were
  to be considered for the provision of AM(R)S
  services it has to be ensured that it does not
  place any additional constraint on RNSS systems.
• In the event that spectrum is made available for
  use by UAVs, APT Administrations are of the view
  that appropriate spectrum should also be made
  available for telecommand purposes to facilitate
  the safe operation of UAVs, subject to not
  adversely affecting existing or planned services.
• One Administration also supports a global
  allocation to the aeronautical mobile (R) service
  in the frequency bands 116-117.975 MHz. Another
  Administration does not support the allocation of
  the aeronautical mobile (R) service to 960-1 024
  MHz due to its extensive use of this band for
  Distance Measuring Equipment (DME).

• Agenda Item 1.6 to study current satellite
  frequency allocations, that will support the
  modernization of civil aviation telecommunication
  systems, taking into account Resolution 415 (WRC
  03)
• Proposed by Kenya and Uganda as a method of
  improving developing countries CNS/ATM aviation
  infrastructure by reducing reliance on expensive
  and unreliable terrestrial systems
• Studies considering the recognition of satellite
  communication systems such as VSAT for
  aeronautical safety applications
• Also a proposal for an AMSS (s-E) secondary
  allocation to compliment the existing AMSS (E-s)
  secondary allocation in the band 14-14.5 GHz.
  Not intended for aeronautical SOL communications

• Agenda Item 1.6 to study current satellite
  frequency allocations, that will support the
  modernization of civil aviation telecommunication
  systems, taking into account Resolution 415 (WRC
  03)
• a. APT Administrations are of view that
• 1. existing Fixed Satellite Service (FSS)
  spacecraft and appropriate earth stations can be
  used to create, augment or enhance infrastructure
  to support civil aviation telecommunications
  services, including ICAO CNS/ATM applications.
• 2. the use of satellite-based facilities in
  connection with civil aviation applications will
  contribute to the overall improvement of the
  aviation communications infrastructure in
  developing countries and remote areas. However,
  it should be ensured that these applications are
  consistent with existing satellite frequency
  allocations.
• 3. guidance material in the form of an ITU-R
  Recommendation or handbook should be prepared
  detailing the spectrum management issues
  associated with using VSAT networks for
  aeronautical telecommunication applications,
  noting that this spectrum may also support other
  non-aviation users.

• Agenda Item 1.6 to study current satellite
  frequency allocations, that will support the
  modernization of civil aviation telecommunication
  systems, taking into account Resolution 415 (WRC
  03)
• b. One Administration expressed their support to
  the allocation of the following bands for the use
  of the aeronautical mobile-satellite service on a
  secondary basis
• Region 1 10.7-11.7 GHz and 12.5-12.75 GHz (s-E)
• Region 2 10.7-12.2 GHz (s-E)
• Region 3 10.7-11.7 GHz and 12.2-12.75 GHz
  (s-E),
• as the companion downlink allocation to the
  existing AMSS uplink allocation in the band
  14-14.5 GHz, providing such allocation does not
  have any adverse impact on existing services in
  these bands. This allocation is not intended to
  be used for aeronautical safety-of-life ICAO
  CNS/ATM communications.
• One Administration expressed different view that
  does not support the opening of the issue
  relating to the secondary 14 GHz uplink
  allocation to AMSS adopted by WRC-03. Such
  allocation to the uplink AMSS was done with
  considerable difficulties at WRC-03 under Agenda
  Item 1.11 of the Conference. Now that, by a way
  of consensus, the uplink allocation is made, we
  do not support any argument that one needs to
  allocate a secondary downlink at 10-11 GHz to
  complement the above-mentioned uplink. The
  agreement reached at WRC-03 for the uplink on 14
  GHz, secondary basis, was on the assumption that
  its associated downlink would operate under RR
  4.4.

• Agenda Item 1.4 to consider frequency-related
  matters for the future development of IMT 2000
  and systems beyond IMT 2000 taking into account
  the results of ITU R studies in accordance with
  Resolution 228 (Rev.WRC 03)
• An extract
• APT administrations are of the view that the
  bands currently allocated to aeronautical mobile
  (R) services and aeronautical radio determination
  services related to safety of life should not be
  identified for use for IMT applications.
