  1. Regional Seminar on radio-frequency spectrum for international civil aviation 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). Presented by Robert Witzen Technical Officer, CNS Section ANB/ICAO Nairobi, Kenya 17-18 September 2007

  2. 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 Bangkok, Thailand 8-10 January 2003

  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. Bangkok, Thailand 8-10 January 2003

  4. Errors in the Radio Regulations • 328.6-335.4 MHz AERONAUTICAL RADIONAVIGATION 5.2585.258 5.259 Bangkok, Thailand 8-10 January 2003

  5. 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proposal to remove Indonesia from this footnote does not affect the AFI Region; ICAO has no opinion on this proposal Outdated provisions Nairobi, Kenya 17-18 September 2007

  6. Outdated provisions 5.203 In the band 136-137 MHz, existing operational meteorological satellites may continue to operate, under the conditions defined in No. 4.4 with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 Nairobi, Kenya 17-18 September 2007

  7. Outdated provisions 5.203A Additional allocation:  in Israel, 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) The proposal to delete this provision from the Radio Regulations is supported by ICAO Nairobi, Kenya 17-18 September 2007

  8. Outdated provisions 5.203B Additional allocation:  in Saudi Arabia, United Arab Emirates, Oman and Syrian Arab Republic, the band 136-137 MHz is also allocated to the fixed and mobile, except aeronautical mobile, services on a secondary basis until 1 January 2005.     (WRC-03) The proposal to delete this provision from the Radio Regulations is supported by ICAO Nairobi, Kenya 17-18 September 2007

  9. 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 Nairobi, Kenya 17-18 September 2007

  10. 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, Greece, Guinea, Guinea-Bissau, Hungary, Kazakhstan, Lithuania, Moldova, Mongolia, Nigeria, Uganda, Uzbekistan, Pakistan, Poland, Kyrgyzstan, the Dem. People’s Rep. of Korea, Romania, Senegal, Swaziland, Tajikistan, Tanzania, Turkmenistan and Ukraine, and until 1 January 2010 in Saudi Arabia, Cameroon, the Libyan Arab Jamahiriya, Jordan, Kuwait, Lebanon, Mali, Mauritania, the Syrian Arab Republic and 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) Nairobi, Kenya 17-18 September 2007

  11. Provisions requiring update Proposed new provision – Countries having fixed service on a primary basis until 1 January 2005 5.362BBAdditional allocation:The band 1 559-1 610 MHz is also allocated to the fixed service on a secondary basis until 1 January 2015 in Germany, Armenia, Azerbaijan, Belarus, Benin, Bosnia and Herzegovina, Bulgaria, Spain, the Russian Federation, France, Gabon, Georgia, Greece, Guinea, Guinea-Bissau, Hungary, Kazakhstan, Lithuania, Moldova, Mongolia, Nigeria, Uganda, Uzbekistan, Pakistan, Poland, Kyrgyzstan, the Dem. People’s Rep. of Korea, Romania, Senegal, Swaziland, Tajikistan, Tanzania, Turkmenistan and Ukraine. 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) 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 Nairobi, Kenya 17-18 September 2007

  12. Provisions requiring update Proposed new provision – Countries having fixed service on a primary basis until 1 January 2005 5.362BA Additional allocation:The band 1 559-1 610 MHz is also allocated to the fixed service on a primary basis until 1 January 2010 in Saudi Arabia, Cameroon, the Libyan Arab Jamahiriya, Jordan, Kuwait, Lebanon, Mali, Mauritania, the Syrian Arab Republic and Tunisia. After this date, 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) For clarity reasons, ICAO can support the proposal Nairobi, Kenya 17-18 September 2007

  13. 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. Nairobi, Kenya 17-18 September 2007

  14. 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 Nairobi, Kenya 17-18 September 2007

  15. 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. Nairobi, Kenya 17-18 September 2007

  16. 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. Nairobi, Kenya 17-18 September 2007

  17. 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. (continued) Nairobi, Kenya 17-18 September 2007

  18. Provisions requiring update 1545-1555 MHz and 1646.5-1656.5 MHz (2) MOD 5.376 Additional allocation: The band 1 646.5-1 656.5 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 aircraft stations directly to terrestrial aeronautical stations, or between aircraft stations to extend or supplement the aircraft-to-satellite 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 Nairobi, Kenya 17-18 September 2007

  19. 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 Reflects a situation already existing in some countries AM(R)S in these bands may add to flexible system design Supported by ICAO Nairobi, Kenya 17-18 September 2007

  20. Provisions requiring update 1610-1626.5 MHz (2) 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 ground-based or satellite-borne facilities and is subject to agreement obtained under No. 9.21. This amendment, which reflects current practice by the Bureau, can be supported by ICAO. Nairobi, Kenya 17-18 September 2007
