• Resolution 950 (Rev.WRC-07)
• Consideration of the use of the frequencies
  between 275 and 3 000 GHz
  
• resolves
• to review No. 5.565 of the Radio Regulations,
  excluding frequency allocations, in order to
  update the spectrum use between 275 GHz and 3 000
  GHz by the passive services at WRC-11, taking
  into account the result of the ITU-R studies
• that administrations may submit for inclusion in
  the Master International Frequency Register
  details on systems which operate between 275 and
  3 000 GHz and which may be recorded by the
  Radiocommunication Bureau under Nos. 8.4, 11.8
  and 11.12,

• to conduct the necessary studies in time for
  consideration by WRC-11 with a view to the
  modification of No. 5.565, including advice on
  the applications suitable for the band 275-3 000

Agenda Item 1.6 - (4)

• Resolution 955 (Rev.WRC-07)
• Consideration of procedures for free-space
  optical links
  
• resolves
• to consider possible procedures for free-space
  optical links, taking into account the results of
  ITU-R studies covering at least sharing aspects
  with other services, a clear definition of the
  band limits and measures to be considered if
  allocations to various services in the Radio
  Regulations above 3 000 GHz are considered
  feasible,
• invites ITU-R
• to conduct the necessary studies in time for
  consideration by WRC-11.

Agenda Item 1.6 (5)
Related ITU-R Recommendation ITU-R RS.1804
(Technical and operational characteristics of
Earth exploration-satellite service (EESS)
systems operating above 3 000 GHz) (2007)
recommends that operators of EESS systems ope
rating above 3 000 GHz should take into account
the possibility of interference from transmitters
of the science services (including those of EESS)
in their selection of mission requirements and
choices of sensor design 2 that studies of int
erference to and from EESS systems operating
above 3 000 GHz should take into account the
technical and operational parameters provided in
Annex 1.

• Resolution 753 (Rev.WRC-07)
• Use of the band 22.55-23.15 GHz by the space
  research service
  
• resolves
• to invite ITU-R to conduct sharing studies
  between space research service systems operating
  in the Earth-to-space direction and the fixed,
  inter-satellite and mobile services in the band
  22.55-23.15 GHz, to recommend appropriate sharing
  criteria for an allocation to the space research
  service in the Earth-to-space direction
• to invite WRC-11 to review the results of the
  studies under resolves 1 and consider the
  inclusion of the sharing criteria within the
  Radio Regulations and appropriate modifications
  to the Table of Frequency Allocations,

• Resolution 754 (Rev.WRC-07)
• Consideration of modification of the
  aeronautical component of the mobile service
  allocation in the 37-38 GHz band for protection
  of other primary services in the band
• resolves
• to invite ITU-R to conduct appropriate studies
  involving the aeronautical mobile service and the
  affected primary services in the band 37-38 GHz
  in order to determine the compatibility of the
  aeronautical mobile service with these other
  services
• to invite WRC-11 to review the results of the
  studies under resolves 1 and consider the
  inclusion of any appropriate compatibility
  criteria within the Radio Regulations or
  appropriate modifications to the Table of

• resolves
• to invite ITU-R to conduct, and complete in time
  for WRC-11, the required studies leading to
  technical and procedural recommendations to the
  Conference enabling it to decide on an
  appropriate method of providing recognition to
  long-established systems, including the
  possibility of making an allocation to the
  meteorological aids service in the frequency
  range below 20 kHz
• 2 that the studies referred to in resolves 1,
  without placing constraints on existing services
  operating in accordance with the Radio
  Regulations, shall include sharing and
  compatibility studies with services already
  having allocations in potential spectrum for
  systems in the meteorological aids service taking
  into account the needs of other services,
