Preparation of WRC-2003

• Fixed Service, High Density Fixed-Satellite
  Service and HAPS

2
CHAPTER 4 of CPM Report

• 1.13 HAPS
• 1.18 FS in the 17.3-17.7 GHz band
• 1.25 HDFSS
• 1.26 ESV
• 1.32 38/40 GHz bands

3
Agenda item 1.13

• To consider regulatory provisions and possible
  identification of existing frequency allocations
  for services which may be used by high altitude
  platform stations, taking into account No. 5.543A
  and the results of the ITU-R studies conducted in
  accordance with Resolutions 122 (Rev.WRC-2000)
  and 734 (WRC-2000)
• Resolution 122 Use of HAPS in Fixed Service
  18-32 GHz (region 3) and 48 GHz
• Resolution 734 Possible use of HAPS in FS and MS
  bands above 3 GHz

4
CEPT view on 1.13

• The general aim of CEPT is the protection of
  existing services or applications from HAPS,
  which are known as presenting a high potential of
  interference.
• The feasibility of the platform still to be
  demonstrated.
• Resolution 122
• the band 27.5-28.35 GHz is of primary interest in
  Europe for FS and FSS. Although the introduction
  of HAPS in the 18-32 GHz range is mainly for the
  Region 3 countries, the possibility of a wider
  introduction has to be considered
• The band 31-31.3 GHz is adjacent to the passive
  band 31.3-31.8 GHz (EESS and Radio astronomy).
  Protection levels for EESS is proposed to be
  specified in the RR
• Resolution 734 CEPT does not support any change
  to the RR or any continuation of studies (no
  bands and no bandwidth requirements)

5
Agenda item 1.18

• To consider a primary allocation to the fixed
  service in the band 17.3-17.7 GHz for Region 1,
  taking into account the primary allocations to
  various services in all three Regions

6
CEPT view on 1.18

• From the revision of the actual Fixed Service use
  and future plans CEPT found that the use and
  interest within Europe is very limited for FS in
  the band 17.3-17.7 GHz
• In addition it is a good candidate for HDFSS (see
  1.25)
• Therefore, a primary allocation is no longer
  requested by CEPT.

7
Agenda item 1.25

• To consider, with a view to global harmonisation
  to the greatest extent possible, having due
  regard to not constraining the development of
  other services, and in particular of the fixed
  service and the broadcasting-satellite service,
  regulatory provisions and possible identification
  of spectrum for high-density systems in the
  fixed-satellite service above 17.3 GHz, focusing
  particularly on frequency bands above 19.7 GHz

8
HDFSS Characterisation

• A High Density application in the Fixed Satellite
  Service (HD-FSS) is one which operates on a
  system in the FSS, deploying a high number of
  ubiquitous earth stations. Satellite systems can
  be of any orbital type, as GSO or non-GSO, and
  using any of the available technologies.
• High-Density applications in the FSS are
  generally characterized as follows
• flexible, rapid deployment
• high frequency reuse
• small antenna size
• low cost terminals

9
HDFSS sharing issues

• Many current FSS bands are shared with FS
• Ubiquitous location of HDFSS terminals do not
  ease sharing
• Statistical studies have been performed which
  result in different situations depending on
• The frequency bands (uplink or downlink)
• Type of FS applications (P-P or P-MP)
• Geographical zone
• Those studies have led to the adoption within
  CEPT of ERC Decisions and in particular
  ERC(00)07 (18 GHz) and ERC(00)09 (28 GHz).

10
CEPT view on 1.25

• Bands proposed by CEPT, for which a consensus is
  expected at the WRC-03
• - 19.7-20.2 GHz
• - 29.5-30 GHz
• - 40-40.5 GHz

11
CEPT view on 1.25

• Bands proposed by CEPT, which are likely to be
  debated at the WRC-03
• - 39.5-40 GHz
• - Parts of the 27.5-29.5 GHz allocated
  exclusively to FSS in the Decision ERC(00)09

12
CEPT view on 1.25

• Bands opposed by CEPT, likely be strongly debated
  at the WRC-03 (protection issues)
• - 17,7-19,7 GHz
• - Other parts of the 27.5-29.5 GHz designated
  for FS in the Decision ERC(00)09
• - 40,5-42 GHz

13
CEPT view on 1.25

• Bands proposed by CEPT and that need a new FSS
  allocation in the downlink, likely also to be
  debated at the WRC-03
• - 17.3-17.7 GHz
• no specific sharing difficulty
• No primary FS allocation (see agenda 1.18)
• - Parts of the band 47.2-50.2 GHz
• - few sharing issues

14
CEPT view on 1.25 Regulatory issues

• The principle of coordination and notification
  of HDFSS stations as Typical stations has been
  studied within ITU-R
• it would obviously ease the task of spatial
  administrations
• it would introduce an unbalanced situation
  between this latter and terrestrial
  administrations
• It also increases the coordination distances
  (worst case calculations)
• Hence, CEPT do not support any regulatory
  modification

15
Agenda item 1.32

• to consider technical and regulatory provisions
  concerning the band 37.5-43.5 GHz, in accordance
  with Resolutions 128 (Rev.WRC-2000) and 84
  (WRC-2000)
• Resolution 84 Adequacy of the power flux
  density (pfd) limits included in article S21-4
  for FSS, MSS and BSS in the bands 37.5-40 GHz and
  40-42.5 GHz
• Resolution 128 Protection of Radio Astronomy
  Service (RAS) in the band 42.5 43.5 GHz from
  unwanted-emissions of FSS and BSS satellites
  transmitting in band 41.5 42.5 GHz

16
Agenda item 1.32

• In Europe, this frequency range is currently
  covered by three ERC decisions
• Decision ERC/DEC(99)15 designating the band
  40.5-43.5 GHz for MWS
• Decision ERC/DEC(00)02 giving priority for FS
  with regards to uncoordinated FSS terminals in
  the band 37.5-39.5 GHz and providing the band
  39.5-40.5 GHz for HDFSS
• Decision ERC/DEC(02)04 giving priority for MWS
  with regards to uncoordinated FSS terminals in
  the band 40.5-42.5 GHz

17
Agenda item 1.32
18
CEPT view on 1.32 (Res. 84)

• CEPT was opposed to any kind of soft segmentation
  on the basis of pfd values
• CEPT supported the limits included in article
  S21-4 on which all administrations or regional
  organisation could elaborate their own policy
• Those views have been globally endorsed within
  ITU-R, recognising the right of administrations,
  if needed, to tighten the pfd on their territory
  in licensing process.

19
CEPT view on 1.32 (Res. 128)

• Consistently with agenda item 1.8.2, CEPT
  support pfd and epfd Out-of-Band (OOB) limits
  applied to FSS and BSS to protect notified
  Radioastronomy stations in the band 42.5-43.5 GHz
  for all type of observations
• Continuum
• VLBI
• Spectral lines, down to 42.5 GHz

20
FS and FSS use and trends

• With regard to FS, CEPT has adopted ECC Report
  003 on current use and future trends post-2002
• There may be a need, after the WRC-03, to
  reinitiate the work within WGFM on HDFSS
  strategic plan within Europe
• Information from satellite industry and operators
  will then be needed
