747 (WRC-03) consider the upgrading of the
radiolocation service to primary allocation
status in the bands 9000 9200 MHz and 9300
9500 MHz and extending by up to 200 MHz the
existing primary allocations to the Earth
exploration-satellite service (active) and the
space research (active) in the band 9500 9800
MHz without placing undue constraints to the
service which the bands are allocated

• Upgrading radiolocation service to primary in
  9000-9200 MHz and 9300-9500 MHz.

WRC-Agenda item 1.5To consider spectrum
requirements and possible additional spectrum
allocation for aeronautical telecommand and
high-bit rate aeronautical telemetry, in
accordance with Resolution 230 (WRC 03)

• CITEL does not support an allocation for AMT in
  the band 5030-5091 MHz. This band remains
  protected for MLS.
• CITEL does not support an allocation for AMT in
  the band 5150 5250 MHz, as AMT is not
  compatible with existing services
• CITEL supports an allocation to aeronautical
  mobile service for AMT in the band 5091-5150 MHz
  limited to air to ground flight test telemetry
  only
• New Resolution to specify sharing conditions in
  the 5091-5150 MHz band AMT5GHz

  band 5000-5030 MHz. (footnote and Resolution
  giving protection to RNSS)
• CITEL IAP does not support AM(R)S in the band
  5030-5091 MHz. (ensures protection of MLS)
• CITEL IAP supports AM(R)S in the band 5091-5150
  MHz (by footnote and Resolution to protect FSS)
• CITEL IAP supports the ICAO position

9
WRC-Agenda item 1.6 (4)and to study current
satellite frequency allocations that will support
the modernization of civil aviation
telecommunication systems, taking into account
Resolution 415 (WRC 03)

• CITEL IAP does not support any modification to
  current satellite allocations in the 10.7 12.75
  GHz band, and NOC to FN 5.504A
• This does not support the ICAO position regarding
  a Recommendation in the RRs for VSAT systems

10
WRC-Agenda item 1.13Taking into account
Resolutions 729 (WRC-97), 351 (WRC-03) and 544
(WRC-03) to review the allocations to all
services in the HF bands between 4 and 10 MHz,
excluding those allocations to service in the
frequency range 7000 7200 KHz and those bands
whose allotment plans are in Appendix 25, 26 and
27 and whose channeling arrangements are in
Appendix 17, taking into account the impact of
new modulation techniques, adaptive control
techniques and spectrum requirements for HF
broadcasting.

• Res. 729
• MOD to Res 729 - Minor modification recognizing
  ITU-R work on adaptive systems. No further work
  required
• ADD New Resolution to determine the suitability
  of changing the radio regulations to allow for
  wider bandwidths to the fixed and mobile services
  (excluding aeronautical mobile service) to
  accommodate advanced HF adaptive systems
• Res. 351
• NOC to Appendix 17
• MOD Res 351 to enable studies for WRC-11
  modification to Article 5
• ADD footnote to maritime mobile bands identified
  for analog services to enable digital
  transmissions
• Res. 544
• NOC - No additional spectrum for broadcasting
  service
• SUP Res 544. Issue has been studied - Do not
  support a future agenda item
• Other Issues -
• NOC - Retain current primary allocation to
  amateur service in Region 2 at 7200-7300 kHz
• This supports the ICAO position

11
WRC-Agenda item 1.16To consider the regulatory
and operational provisions for maritime mobile
service identities (MMSIs) for equipment other
than shipborne mobile equipment taking into
account Resolution 344 (Rev. WRC-03) and 353
(WRC-03)

• CITEL IAP supports the provisions of ITU-R
  Recommendation M.585.4 which extends MMSI
  assignments to aircraft stations and aids to
  navigation.
• This supports the ICAO position.

12
WRC-Agenda item 1.17To consider the results of
ITU-R studies on compatibility between the
fixed-satellite service and other services around
1.4 GHz, in accordance with Resolution 745
(WRC-03)

• CITEL supports the suppression of the secondary
  allocation for MSS feeder links in the bands
  1390-1392 MHz and 1430-1432 MHz. (SUPP 5.339A
  and Res 745)
• CITEL IAP supports the ICAO position.

13
WRC-Agenda item 1.20To consider the results of
the studies and proposals for regulatory
measures, if appropriate, regarding the Earth
exploration-satellite service (passive) from
unwanted emissions of active services in
accordance with Resolution 738 (WRC-03)

• CITEL did not develop an IAP on this agenda item
  to support inclusion of limits for unwanted
  emissions to protect EESS from radar systems
  brought into operation in the future.

14
WRC-Agenda item 1.21To consider the results of
studies regarding the compatibility between the
radio astronomy service and the active space
services in accordance with Resolution 740 (Rev.
WRC-03), in order to review and update, if
appropriate, the tables of threshold levels used
for consultation that appear in the Annex to
Resolution 739 (WRC-03)

• CITEL is of the view that future RNSS systems can
  meet unwanted emissions criteria to protect RAS.
• No provisions proposed for unwanted emissions
  from RNSS systems in the band 1559-1610 MHz.
• Removal of 1559-1610 MHz band from Res 740 for
  further consideration at WRC-11
• CITEL IAP supports the ICAO position.

15
WRC-Agenda item 2To examine the revised ITU-R
Recommendations incorporated by reference in the
Radio Regulations communicated by the
Radiocommunication Assembly, in accordance with
Resolution 28 (Rev. WRC-03), and to decide
whether or not to update the corresponding
references in the Radio Regulations, in
accordance with principles contained in Annex to
Resolution 27 (Rev. WRC-03)

• CITEL proposals do not appear to effect
  aeronautical services, there are 17 IAPs based
  primarily upon CPM Report to update references to
  ITU-R Recommendations already incorporated by
  reference and to modify certain other references
  to clarify their status and remove any ambiguity
• This supports the ICAO position.

16
WRC-Agenda item 7.2To recommend to the Council
items for inclusion in the agenda for the next
WRC, and to give its views on the preliminary
agenda for the subsequent conference and on
possible agenda items for future conferences,
taking into account Resolution 802 (WRC-03)

• CITEL did not develop an IAP to support inclusion
  of an agenda item for WRC-11 to address the MSS
  1.5/1.6 GHz band to secure long term availability
  of spectrum for AMS(R)S.
• CITEL did not develop an IAP to support inclusion
  of an agenda item for WRC-11 for UAS
• These items will be be dealt with by country
  specific proposals to the WRC
