Preparations for WRC-07WRC Agenda item 7.1 to
consider and approve the Report of the Director
of the Radiocommunication Bureau - on the
activities of the Radiocommunication Sector since
WRC-03 - on any difficulties or inconsistencies
encountered in the application of the Radio
Regulations - on action in response to
Resolution 80 (Rev. WRC-2000).
Regional Seminar on radio-frequency spectrum for
international civil aviation
  • Presented by Robert Witzen
  • Technical Officer, CNS Section ANB/ICAO

Part 2 Experiences In The Application Of The
Radio Regulatory Procedures And Other Related
Matters
  • Summary of errors, inconsistencies and obsolete
    parts of the Radio Regulations

3
Errors in the Radio Regulations
  • Appendix 27
  • 27/56 In the aeronautical mobile (R) service the
    use of emissions such as those listed below is
    permissible subject to compliance with the
    special provisions applicable to each case and
    provided that such use does not cause harmful
    interference to other users of the channel
    concerned.

Outdated provisions
  • 5.77 Different category of service  in
    Australia, China, the French Overseas Territories
    of Region 3, India, Indonesia (until 1 January
    2005), Iran (Islamic Republic of), Japan,
    Pakistan, Papua New Guinea and Sri Lanka,
    the  allocation of the band 415-495 kHz to the
    aeronautical radionavigation service is on a
    primary basis. Administrations in these countries
    shall take all practical steps necessary to
    ensure that aeronautical radionavigation stations
    in the band 435-495 kHz do not cause interference
    to reception by coast stations of ship stations
    transmitting on frequencies designated for ship
    stations on a worldwide basis (see
    No. 52.39).     (WRC-2000)No proposals from these
    States to remove their name
  • The proposal to remove Indonesia from this
    footnote does not affect the AFI Region ICAO has
    no opinion on this proposal

Outdated provisions
  • 5.203 In the band 136-137 MHz, existing
    operational meteorological satellites may
    continue to operate, under the conditions defined
    in No. 4.4 with respect to the aeronautical
    mobile service, until 1 January 2002.
    Administrations shall not authorize new frequency
    assignments in this band to stations in the
    meteorological-satellite service.     (WRC-97)
  • The proposal to delete this provision from the
    radio Regulations is supported by ICAO

    Mauritania, Qatar and Zimbabwe, the band 136-137
    MHz is also  allocated to the fixed and mobile,
    except aeronautical mobile (R), services on a
    secondary basis until 1 January 2005.     (WRC-97)

Outdated provisions
  • The proposals to remove 5.203 (meteorological
    satellites), 5.203A (fixed and mobile, except
    aeronautical mobile (R)) and 5.203B (fixed and
    mobile, except aeronautical mobile) will increase
    the availability of the band 136-137 MHz for the
    aeronautical mobile (R) service
  • Opinion of countries mentioned in 5.203A and
    5.203 B important
  • 136-137 MHz prime candidate for global
    implementation of air-ground data links

Provisions requiring update
  • Current provision
  • 5.362B Additional allocation  The band
    1 559-1 610 MHz is also allocated to the fixed
    service on a primary basis until 1 January 2005
    in Germany, Armenia, Azerbaijan, Belarus, Benin,
    Bosnia and Herzegovina, Bulgaria, Spain, the
    Russian Federation, France, Gabon, Georgia,

    Tunisia. After these dates, the fixed service may
    continue to operate on a secondary basis until
    1 January 2015, at which time this allocation
    shall no longer be valid. Administrations are
    urged to take all practicable steps to protect
    the radionavigation-satellite service and the
    aeronautical radionavigation service and not
    authorize new frequency assignments to
    fixed-service systems in this band.     (WRC-03)

Provisions requiring update
  • Proposed new provision Countries having fixed
    service on a primary basis until 1 January 2005

    service and the aeronautical radionavigation
    service and not authorize new frequency
    assignments to fixed-service systems in this
    band.     (WRC-03)
  • This changes the note in the current 5.362B
    after these date the fixed service may continue
    to operate on a secondary basis into an
    allocation on a secondary basis.
  • For clarity reasons, ICAO can support the proposal

Outdated provisions
  • 5.433 In Regions 2 and 3, in the band 3 400-3 600
    MHz the radiolocation service is allocated on a
    primary basis. However, all administrations
    operating radiolocation systems in this band are
    urged to cease operations by 1985. Thereafter,
    administrations shall take all practicable steps
    to protect the fixed-satellite service and
    coordination requirements shall not be imposed on
    the fixed-satellite service.
  • The proposal to delete this provision from the
    Radio Regulations is supported by ICAO. This band
    is not known as being used for aeronautical
    radionavigation systems (such as radar systems)
    for civil aviation.

Outdated provisions
  • 5.476 In the band 9 300-9 320 MHz in the
    radionavigation service, the use of shipborne
    radars, other than those existing on
    1 January 1976, is not permitted until
    1 January 2001.
  • The proposal to delete this provision from the
    Radio Regulations is supported by ICAO.
  • Limited extension through a country footnote may
    be required in some countries

Provisions requiring update
  • Wording in a number of footnotes
  • and shall not constrain the development and
    use of the PPP service in the band yyy-zzz MHz
  • Considered by the Bureau as an operational
    provision that not defines the status between
    services.
  • Could be replaced with shall not cause harmful
    interference to nor claim protection from ..
    This would be sufficient to define the status
    between two services.

Provisions requiring update 1545-1555 MHz and
1646.5-1656.5 MHz
  • Additional allocation to the aeronautical mobile
    (R) service
  • 5.357 Transmissions in the band 1 545-1 555 MHz
    from terrestrial aeronautical stations directly
    to aircraft stations, or between aircraft
    stations, in the aeronautical mobile (R) service
    are also authorized when such transmissions are
    used to extend or supplement the
    satellite-to-aircraft links.
  • 5.376 Transmissions in the band 1 646.5-1 656.5
    MHz from aircraft stations in the aeronautical
    mobile (R) service directly to terrestrial
    aeronautical stations, or between aircraft
    stations, are also authorized when such
    transmissions are used to extend or supplement
    the aircraft-to-satellite links.

Provisions requiring update 1545-1555 MHz and
1646.5-1656.5 MHz
  • Radio Regulations Board (RRB)considered these
    provisions as an additional allocation to the
    aeronautical mobile (R) service.
  • Proposal to incorporate the ruling of the RRB
    into the Radio Regulations as follows
  • MOD 5.357 Additional allocation The band
    1 545-1 555 MHz is also allocated to the
    aeronautical mobile (R) service on a primary
    basis. The use of this band in the aeronautical
    mobile (R) service is limited to transmissions
    from terrestrial aeronautical stations directly
    to aircraft stations, or between aircraft
    stations to extend or supplement the
    satellite-to-aircraft links.

  • The amendment will clarify the meaning of 5.357
    and 5.376
  • Reflects a situation already existing in some
    countries
  • AM(R)S in these bands may add to flexible system
    design
  • Supported by ICAO

Provisions requiring update 1610-1626.5 MHz
  • 5.366 The band 1 610-1 626.5 MHz is reserved on a
    worldwide basis for the use and development of
    airborne electronic aids to air navigation and
    any directly associated ground-based or
    satellite-borne facilities. Such satellite use is
    subject to agreement obtained under No. 9.21.
  • The RRB established a rule of procedure
    considering this an additional allocation to the
    radionavigation-satellite service.
  • The amendment will clarify the meaning of 5.357
    and 5.376

  • Proposed amendment
  • MOD 5.366 Additional allocation The band
    1 610-1 626.5 MHz is also allocated to the
    aeronautical radionavigation-satellite service on
    a primary basis. The use of this band in the
    aeronautical radionavigation-satellite service is
    limited to airborne electronic aids to air
    navigation and any directly associated
