 FCC  SEEKS  COMMENT  ON  RECOMMENDATIONS  APPROVED  BY  THE  ADVISORY  COMMITTEE  FOR  THE  2007  WORLD  RADIOCOMMUNICATION 
 CONFERENCE 

 IB  Docket  No.  04-  286 
 On  April  27,  2006,  the  World  Radiocommunication  Conference  Advisory  Committee  (WRC-  07  Advisory  Committee)  approved  and  submitted  for  Commission  consideration  its  recommendations  with  regard  to  a 
 number  of  issues  that  will  be  considered  by  the  2007  World  Radiocommunication  Conference  (WRC-07).  1  These  recommendations  are  attached  to  this  Public  Notice. 

 Based  upon  an  initial  review  of  the  attached  WRC-  07  Advisory  Committee  recommendations,  the  International  Bureau,  in  coordination  with  other  FCC  Bureaus  and  Offices,  tentatively  concludes  that  it 
 can  generally  support  these  recommendations.  The  International  Bureau,  however,  notes  the  differing  views  expressed  by  WRC-  03  Advisory  Committee  participants  in  documents  WAC/  102  and  WAC/  104. 

 The  FCC  seeks  comment  on  the  attached  recommendations  as  well  as  recommendations  that  appear  in  all  of  the  WRC-  07  Advisory  Committee  documents.  2  The  FCC  also  seeks  comment  on  the  attached  draft 
 preliminary  views  and  proposals  that  have  been  developed  by  the  Executive  Branch  Agencies  and  submitted  to  the  FCC  by  the  National  Telecommunications  and  Information  Administration  (NTIA). 
 Finally,  the  FCC  seeks  comment  on  the  International  Bureaus  initial  conclusions  with  regard  to  the  WRC-  07  Advisory  Committee  recommendations. 

 The  comments  provided  by  interested  parties  will  assist  the  FCC  in  its  upcoming  consultations  with  the  U.  S.  Department  of  State  and  NTIA  in  the  development  of  U.  S.  positions  for  WRC-  07.  As  the 
 recommendations  that  are  attached  to  this  Public  Notice  may  evolve  in  the  course  of  interagency  discussions  as  WRC-  07  nears,  they  do  not  constitute  final  U.  S.  Government  position  on  any  issue. 

 1  The  WRC-  07  Advisory  Committee  was  established  by  the  FCC  in  January  2004  to  assist  the  FCC  in  developing 
 proposals  for  WRC-  07.  Since  its  inception,  the  WRC-  07  Advisory  Committee  has  developed  and  submitted  recommendations  and  preliminary  views  for  Commission  consideration.  See,  e.  g.,  The  FCCs  Advisory  Committee

 I.  Recommendations  by  the  Advisory  Committee  for  the  2007  World  Radiocommunication  Conference: 
 INFORMAL  WORKING  GROUP  1  (IWG-  1) 
 Terrestrial  and  Space  Science  Services 

 Document  WAC/  111(  27.04.06): 
 DRAFT  PROPOSALS  FOR  THE  WORK  OF  THE  CONFERENCE 
 Agenda  item  1.5:  to  consider  spectrum  requirements  and  possible  additional  spectrum  allocations  for  aeronautical  telecommand  and  high  bit-  rate  aeronautical  telemetry,  in  accordance  with  Resolution  230 

 (WRC-  03); 
 Background  Information:  This  agenda  item  seeks  to  address  a  growing  demand  for  spectrum  that  is  allocated  for  wideband  aeronautical  telemetry  and  associated  telecommand.  There  is  a  large  and  growing 
 shortfall  in  spectrum  that  is  necessary  to  conduct  aeronautical  telemetry.  The  shortfall  is  exacerbated  by  the  loss  of  telemetry  spectrum  diverted  to  other  than  telemetry  applications.  As  indicated  in  the  responses  to 
 ITU-  R  Question  231/  8,  additional  spectrum  is  necessary  due  to  rapidly  increasing  data  rates  associated  with  the  testing  of  new  and  emerging  technologies.  For  example,  newer  technologies  rely  increasingly  on  high-resolution 
 video  for  monitoring  aircraft  functions  or  increased  use  of  computer  based  aircraft  systems.  Without  access  to  additional  spectrum,  aeronautical  development  would  be  subject  to  escalating  delays  and 
 costs,  and  the  growth  of  the  aerospace  industry  would  be  impaired  (including  equipment  manufacturers,  civilian  programs  and  test  ranges,  and  airlines).  New  worldwide  telemetry  spectrum  will  aid  numerous 
 countries  and  the  international  aeronautical  community  as  administrations  continue  to  support  their  national  airlines  and  some  administrations  initiate  their  own  test  programs.  Existing  international  allocations  used  for 
 aeronautical  telemetry  will  need  to  remain  available.  Aeronautical  mobile  telemetry  (  AMT)  is  an  application  within  the  mobile  service.  Depending  on  the 
 extent  to  which  new  AMT  spectrum  requirements  can  be  fulfilled  using  Primary  Mobile  Service  allocations,  it  is  important  that  the  suitability  of  additional  spectrum  for  AMT  be  studied  (  suitable  as  defined  below). 
 International  recognition  of  bands  suitable  for  AMT  will  not  only  encourage  international  harmonization  of  test  equipment,  but  also  provide  assurance  to  Administrations  that,  based  on  technical  studies  conducted  in 
 the  ITU-  R,  implementation  of  wideband  telemetry  systems  can  be  accomplished  by  those  Administrations  wishing  to  do  so  without  disrupting  other  services  using  the  bands.  This  will  also  enable  manufacturers  to 
 offer  prospective  customers  aircraft  with  common  test  equipment  packages,  and  thus  help  airlines  achieve  additional  economies  in  the  aircraft  life-  cycle  cost.  Moreover,  by  establishing  conditions  under  which  AMT 
 use  of  a  band  would  be  suitable,  incumbent  users  of  the  spectrum  can  be  assured  that  they  will  not  experience  unacceptable  interference,  and  manufacturers  and  test  ranges  will  have  a  measure  of  additional 
 certainty  for  the  substantial  investment  in  range  infrastructure  that  will  be  incurred  in  equipping  aircraft  to  use  new  bands  deemed  suitable  for  AMT. 
 The  need  for  additional  spectrum  has  been  studied  by  several  administrations.  The  requirement  may  differ  depending  on  national  and  regional  needs.  It  is  not  necessary  to  fulfill  all  AMT  requirements  in  only  one 
 band.  The  U.  S.  requires  an  additional  650  MHz  of  spectrum  for  aeronautical  flight  test  telemetry.  The  new  requirements  for  aeronautical  telemetry  are  only  in  the  air-  to-  ground  direction  inasmuch  as  telecommand 
 functions  (i.  e.,  ground-  to-  air  transmissions)  can  be  accommodated  in  other  bands  used  for  telemetry.  In  addition,  this  new  AMT  spectrum  will  not  be  used  for  the  protection  of  life  and  property.  The  latter  AMT 
 applications  will  continue  to  be  accommodated  in  other  bands  used  for  telemetry  (see  Nos.  5.342,  5.  343,  and  5.  394  in  the  Radio  Regulations).  Hence,  aeronautical  mobile  telemetry  applications  in  new  spectrum  will  not 
 require  the  level  of  protection  associated  with  operations  in  other  telemetry  bands.  ITU-  R  WP  8B  conducted  numerous  studies  of  bands  that  could  be  used  to  satisfy  the  requirements  of 
 wideband  aeronautical  telemetry  applications.  Several  bands  were  studied  for  suitability  to  implement  AMT  given  the  other  co-  primary  services  in  the  band.  These  are  the  4  400-  4  940,  5  925-  6  700,  and  5  091-  5  150 
 MHz  bands.  It  is  expected  that  the  implementation  of  wideband  telemetry  may  require  avoiding  co-frequency  operations  with  other  co-  primary  services  that  utilize  these  bands  in  the  same  geographic  area. 
3

 This  will  likely  mean  that  the  spectrum  requirement  for  AMT  would  be  satisfied  using  portions  of  each  of  the  bands  studied  and  considered  to  be  suitable  for  AMT  implementation.  Suitable  means,  in  this  context, 
 that  AMT  can  be  implemented  compatibly  with  other  co-  primary  services  utilizing  the  band,  assuming  the  implementation  is  in  accordance  with  the  criteria  set  forth  in  the  resolutions  attached. 
 The  ITU-  R  studies  have  demonstrated  that  aeronautical  mobile  telemetry  for  flight  test  purposes  can  be  implemented  in  these  bands  without  adversely  affecting  the  operation  of  existing  systems  and  allocated 
 services.  However,  the  ability  to  implement  AMT  in  some  areas  and  in  some  portions  of  the  bands  may  be  restricted  based  on  deployment  intensity  of  other  co-  primary  service  stations  that  are  ground-  based,  such  as 
 the  Fixed  Service  (FS)  stations,  in  the  same  vicinity.  Application  of  frequency  coordination  will  ensure  that  AMT  is  implemented  such  that  other  services  and  systems  are  not  negatively  impacted.  The  studies  also 
 show  that  there  would  not  be  undue  constraints  placed  on  future  deployment  of  systems  in  the  co-  allocated  services,  provided  applications  are  limited  to  flight  testing  conducted  in  specific  geographic  areas. 
 In  cases  where  AMT  operations  are  in  radio  LOS  of  Radio  Astronomy  observatories  as  could  be  determined  using  a  500  km  coordination  distance,  it  may  be  possible  to  arrange  AMT  time-  sharing  with  those 
 observatories  to  enable  AMT  use  of  the  4825-  4835  MHz  band.  Rather  than  the  more  aggressive  approach  of  designating  or  identifying  bands  for  AMT  on  a  global 
 basis,  which  could  lead  to  a  perception  that  other  services  in  the  bands  may  have  a  lesser  status,  the  approach  for  regulatory  accommodation  of  AMT  has  been  to  simply  determine  the  suitability  of  certain  bands  for  the 
 implementation  of  AMT  based  on  compatibility  studies.  This  approach  was  in  part  based  on  the  realization  that  the  necessary  AMT  operational  or  implementation  constraints  will  influence  decisions  on  AMT 
 implementation  in  each  administration.  Since  the  conditions  under  which  AMT  could  be  implemented  can  vary  by  administration,  the  approach  maximizes  the  flexibility  of  implementing  AMT. 
 Any  authorization  of  AMT  operations  within  these  bands  would  be  decided  by  individual  administrations,  and  would  be  specifically  limited  to  testing  of  aircraft  at  designated  flight  test  areas  in  the  air-  to-  ground 
 direction  within  those  individual  countries.  According  to  No.  5.  444  of  the  Radio  Regulations,  the  5  091-  5  150  MHz  band  is  to  be  used  by  the  MLS  (Microwave  Landing  System)  with  precedence  given  to  this 
 international  standard  system.  However,  the  band  5  091-  5  150  MHz  is  not  yet  in  use  by  MLS.  The  5  091-  5  150  MHz  band  is  already  allocated  to  the  Aeronautical  radio  navigation  service  (ARNS)  on  a 
 primary  basis  in  all  Regions  and  is  also  allocated  to  the  fixed-  satellite  service  (FSS)  (Earth-  to-  space)  on  a  primary  basis.  This  FSS  allocation  is  limited  to  feeder  links  of  non-  geostationary  mobile-  satellite  systems  in 
 the  mobile-  satellite  service  and  is  subject  to  coordination  under  No.  9.11A.  Test  aircraft  are  not  intended  to  use  ground-  to-  air  transmissions  in  this  ARNS  band.  WP  8B  is  also  considering  the  band  5  091-  5  150  MHz 
 under  agenda  item  1.6  for  the  purpose  possible  allocation  to  the  aeronautical  mobile  (R)  service. 

 Proposal 
 USA/  /01  ADD  5.XXX  The  bands  4  400-  4  940  MHz  and  5  925  -  6  700  MHz  are  suitable  for  the  implementation  of 
 aeronautical  mobile  telemetry  applications  for  flight  test  transmissions  by  aircraft  stations  to  aeronautical  stations.  Any  such  use  does  not  preclude  the  use  of  these  bands  by  other  mobile  service  applications  or  by 
 other  services  to  which  these  bands  are  allocated  on  a  co-  primary  basis  and  does  not  establish  priority  in  the  Radio  Regulations.  Resolution  XXX  (WRC-  07)  shall  apply.  (WRC-  07) 
 Reasons:  A  footnote  as  above  could  be  used  to  satisfy  a  portion  of  the  650  MHz  spectrum  requirement.  The  advantage  of  having  such  a  footnote  is  it  merely  states  that  the  bands  are  suitable  and  that,  via  the  provisions 
 of  Resolution  XXX,  AMT  for  flight  test  could  share  spectrum  without  causing  undue  constraints  on  other  co-primary  services  in  the  band(  s).  Furthermore,  a  finding  that  spectrum  is  suitable  for  AMT  implementation 
 inherently  would  not  preclude  use  of  the  bands  by  other  co-  primary  services.  Resolution  XXX  (WRC-  07),  to  be  finalized  upon  receipt  of  WP9Ds  response  to  a  WP8B  liaison  statement,  will  outline  the  sharing 
 conditions  in  the  band(  s).

 5.  ZZZ  The  band  5  091-  5  150  MHz  band  is  also  allocated  to  the  aeronautical  mobile  service  and  is  limited  to  flight  test  telemetry  transmissions  by  aircraft  stations  to  aeronautical  stations.  This  does  not  preclude  the  use 
 of  this  band  by  other  services  to  which  this  band  is  allocated  on  a  co-  primary  basis  and  does  not  establish  priority  in  the  Radio  Regulations.  Resolution  ZZZ  (WRC-  07)  shall  apply.  (WRC-  07) 
 Reasons:  This  allocation  is  necessary  for  implementation  of  AMT  in  the  band  5  091-  5  150  MHz.  The  footnote  will  ensure  that  the  new  allocation  to  AMS  is  limited  to  air-  to-  ground  fight  test  telemetry  only. 
 Resolution  ZZZ  (WRC-  07),  to  be  finalized,  will  outline  the  sharing  conditions  in  the  band. 

 USA/  /03  MOD  5.  442  In  the  band  bands  4  825    4  835  MHz  and  4  950-  4  990  MHz,  the  allocation  to  the  mobile  service  is 
 restricted  to  the  mobile,  except  aeronautical  mobile,  service.  In  the  band  4  825    4  835  MHz  applications  in  the  aeronautical  mobile  service  are  limited  to  flight  test  telemetry  transmissions  by  aircraft  stations  to 
 aeronautical  stations,  and  Resolution  XXX  (WRC-  07)  shall  apply. 
 Reasons:  This  modification  to  No.  5.442  exempts  AMT  from  the  aeronautical  mobile  exclusion,  consistent  with  compatibility  studies,  and  the  Resolution  specifies  an  appropriate  coordination 

 trigger.

 e)  that  depending  on  frequency  usage  by  other  systems  and  services  in  the  vicinity  of  flight  test  ranges,  coordination  may  reveal  that  some  portions  of  the  bands  4  400    4  940  and  5  925  -  6  700  MHz 
 may  not  be  available  for  AMT  or  may  be  restricted  with  respect  to  AMT  use,

 Comments  of  IWG-  1  on  Draft  U.  S.  Proposal  from  Exec.  Branch  Agencies  on  WRC-  07  Agenda  Item  1.20 

 IWG-  1  has  considered  the  terrestrial  elements  of  the  draft  U.  S.  proposal  for  WRC-  07  Agenda  Item  1.20  from  the  Executive  Branch  agencies.  It  offers  the  following  comments: 
 1.  IWG-  1  observes  that  it  is  premature  for  the  United  States  to  assert,  in  the  background  or  in  the  reasons  for  any  specific  proposal,  that  values  proposed  for  the  protection  of  the  EESS  (passive)  are  based  on  an 
 assessment  of  the  impact  on  the  relevant  active  service.  To  the  extent  that  any  ITU-  R  studies  have  even  considered  the  impact  on  the  active  service  involved    a  requirement  of  both  Resolution  738  (WRC-  03) 
 and  the  agenda  item    no  conclusions  have  yet  been  reached,  which  calls  into  question  the  proposals  for  specific  levels  at  this  time.  The  terrestrial  industry  is  continuing  to  address  this  question  with  respect  to 
 the  operation  of  stations  in  the  1350-  1400  MHz,  1427-  1452  MHz,  31-  31.3  GHz  and  51.4-  52.6  GHz  bands. 

 2.  IWG-  1  is  concerned  with  the  proposal  for  mandatory  limits  on  fixed  service  station  emissions  into  adjacent  bands.  For  protection  against  unacceptable  interference  caused  by  unwanted  emissions, 
 mandatory  limits  may  be  without  precedent  in  the  RRs.  The  language  in  the  Exec.  Branch  agencies  proposals  for  new  footnotes  (including  5.  AAA,  5.  CCC,  and  5.  EEE)  would  appear  to  invite  BR 
 examination  under  Art.  11  of  compliance  with  unwanted  emission  limits.  Even  if  BR  examination  is  not  what  the  Exec.  Branch  agencies  contemplate,  the  mandatory  nature  of  the  wording  does  not  clearly 
 exclude  examination,  and  has  serious  negative  implications  for  the  operation  and  evolution  of  advanced  services  in  the  affected  active  service  bands.  In  Document  WAC/  096,  a  redline  of  the  Exec.  Branch 
 agencies  proposal  for  Agenda  Item  1.20,  IWG-  1  offers  suggestions  for  the  wording  of  the  proposed  footnotes  that  aligns  the  notes  generally  with  the  approach  taken  by  WRC-  03  with  respect  to  protection  of 
 the  radioastronomy  service  from  detrimental  interference  (see  Resolution  739  (WRC-  03)),  and  removes  any  suggestion  that  the  footnotes  would  require  BR  examination.

 Document  WAC/  096(  27.04.06):  DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 WRC-  07  Agenda  Item  1.20  3  :  to  consider  the  results  of  studies,  and  proposals  for  regulatory  measures,  if  appropriate,  regarding  the  protection  of  the  Earth  exploration-  satellite  service  (passive)  from 
 unwanted  emissions  of  active  services  in  accordance  with  Resolution  738  (WRC  03); 
 Background  Information:  The  resolves  in  Resolution  738  calls  for  three  actions:  1)  study  the  compatibility  between  EESS  (passive)  and  the  corresponding  active  services  listed  in  the  Table  in 
 Resolution  738  to  update  Recommendation  ITU-  R  SM.  1633  or  develop  additional  Recommendations;  2)  further  study  the  impact  of  implementing  the  values  in  considering  f  )  and  g)  in  the  bands  31 
 31.3  GHz  and  51.4  52.6  GHz  for  unwanted  emissions  of  systems  operating  in  Region  2  and  3,  taking  into  account  that  the  impact  on  fixed-  service  systems  in  Region  1  is  documented  in  ITU-  R 
 Recommendation  SM.  1633;  and  3)  review  the  results  of  studies  in  1)  and  2)  in  order  to  consider  regulatory  measures,  if  appropriate,  to  ensure  the  protection  of  the  EESS  (passive)  operating  in  the 
 bands  listed  in  the  table  in  Resolution  738  (WRC  03)  from  unwanted  emissions  of  active  services  operating  in  the  corresponding  bands  while  taking  into  account  the  impact  on  all  concerned  services  of 
 implementing  or  not  implementing  such  measures.  The  table  below  shows  the  frequency  band  and  radiocommunication  service  combinations  within  the  scope  of  the  agenda  item. 

 Studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  active  services  in  some  of  these  bands  do  not  produce  significant  unwanted  emissions  in  the  adjacent  passive  band.  However,  active

 between  the  active  services,  and  the  differences  in  the  use  of  the  active  and  passive  services  from  band  to  band,  the  solutions  for  this  agenda  item  have  been  determined  on  a  band-  by-  band  and  service-  by-service 
 basis.  [The  proposed  solutions  were  determined  considering  the  impact  to  both  the  active  and  passive  services.] 

 Resolution  738  can  be  suppressed,  and  there  is  no  need  for  an  agenda  item  dealing  with  unwanted  emission  levels  in  EESS  (passive)  bands  for  the  next  Conference.

 permissible  interference  threshold  in  Recommendation  ITU  R  SA.  1029  2,  any  interference  would  occur  for  only  short  time  periods  and  would  be  readily  discernible  by  users  of  the  remote  sensing  data, 
 allowing  corrupted  data  to  be  discarded.  The  remaining  uncorrupted  data  is  expected  to  satisfy  the  scientific  objectives  of  the  EESS  missions.  Studies  also  show  that  radars  would  experience 
 unacceptable  degradation  in  operational  coverage  and  range,  target  resolution,  and  accuracy  if  required  to  meet  unwanted  emission  limits  in  the  1  400  1  427  MHz  band.  As  with  other  pairs  of  active  and 
 passive  bands,  use  of  portions  of  the  allocated  bands  must  not  be  restricted.  Radars  would  suffer  an  increased  likelihood  of  interference  from  other  radars  and  a  reduction  in  coverage  range,  while  a 
 reduced  bandwidth  would  be  inadequate  for  remote  sensing  requirements.

 Reasons:  Results  of  studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  fixed-satellite  service  uplink  transmitters  operating  in  bands  adjacent  to  then  50.2-  50.4  GHz  passive 
 band  can  cause  significant  levels  of  unwanted  emissions  in  the  50.2-  50.4  GHz  passive  band.  The  level  of  regulatory  protection  of  the  EESS  (passive)  from  harmful  interference  that  may  be 
 caused  by  the  unwanted  emissions  of  active  services  is  provided  by  No.  4.7.

 DOCUMENT  WAC/  097(  27.04.06) 
 Proposed  Modification  to  NTIA/  RCS  proposal  for  A.  I.  7.2  (Space  Research-  22GHz)  The  NTIA  in  a  communication  from  it  Associate  Administrator  for  spectrum,  has  forwarded  to  the  WAC 
 a  proposal  related  to  Agenda  Item  7.2  of  WRC-  07.  This  agenda  item  concerns  proposals  for  the  agenda  of  WRC-  10.  The  proposal  of  interest  states: 

 2.  X.  B  to  consider  the  addition  of  up  to  a  500  MHz  primary  space  research  service  (Earth-  to-  space)  allocation  in  the  22.55-  23.55  GHz  band,  taking  into  account  the  results  of  ITU-  R  studies  and  recognizing 
 the  need  to  protect  existing  systems  in  the  band. 
 The  background  information  in  this  draft  proposal  indicates  that  the  suggested  new  allocation  is  required  to  provide  for,  a  companion  uplink(  Earth-  to-  space)  band  to  provide  the  mission  data,  command  and 
 control  links  for  referenced  NASA  missions  to  the  moon  both  robotic  and  manned.  It  is  further  indicated  that  such  an  allocation  is  desirable  be  in  close  proximity  to  the  ISS  links  in  the  25.  25-  27.  5  GHz  allocation. 

 It  is  certainly  clear  that  this  is  an  important  mission  and  clearly  needs  spectrum  support.  It  is  also  clear  that  the  referenced  ISS  allocation  is  already  extensively  used  and  is  expected  to  continue  to 
 be  by  both  the  Iridium  system  and  other  NASA  ISS  links.  The  Iridium  ISS  links  operate  in  the  band  23.183-  23.377  GHz.  Of  concern  is  that  when  an  international 
 allocation  is  adopted  in  Article  5  of  the  Radio  Regulations  it  is  available  to  all  189  members  of  the  ITU.  This  means  that  there  could  be  any  number  of  Administrations  requesting  to  use  the  band,  and 
 particularity  since  this  is  proposed  to  be  an  uplink  transmission  could  present  sharing  difficulties. 
 As  may  not  be  apparent  the  capability  offered  by  non-  GSO  MSS  systems  such  as  Iridium  Have  become  increasingly  important  as  the  last  communication  link  in  the  context  of  emergencies  and 
 natural  disasters  cause  by  Tsunamis,  Hurricanes,  and  earth  quakes.  The  ISS  links  are  critical  to  providing  the  associated  services. 

 The  importance  of  the  NASA  mission  is  recognized,  however,  it  appears  that  such  a  requirement  could  be  met  through  an  appropriate  footnote  to  the  US  table  of  allocations.  However,  alternatively,  given  the 
 requirement  indicated,  it  could  be  accommodated  through  a  modification  of  this  proposal  which  avoids  conflict  with  the  Iridium  ISS  links.  The  NASA  requirement  is  for  500  MHz.  This  requirement  can  easily 
 be  accommodated  in  the  lower  half  of  the  existing  ISS  allocation.  Therefore  if  an  agenda  item  is  really  necessary  the  proposed  frequency  range  in  the  NTIA/  RCS  proposal  should  be  changed  to 
 22.55-  23.05  GHz.  This  should  be  reflected  in  the  text  of  the  proposal  and  the  associated  Resolution.  A  proposed  modification  to  reflect  this  is  attached. 

 In  summary,  it  appears  that  Iridium  concerns  could  be  addressed  by  either  providing  for  the  requirement  through  a  US  domestic  footnote  or  by  a  small  change  in  the  suggested  proposal  by  referencing  only  the 
 lower  half  of  the  ISS  allocation  in  the  22.  55-  23.55  GHz  band.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 WRC-  07  Agenda  Item  1.8  (Res.  145  (WRC-  03)  only):  to  consider  the  results  of  ITU-  R  studies  on  technical  sharing  and  regulatory  provisions  for  the  application  of  high  altitude  platform  stations 
 operating  in  the  bands  27.5-  28.35  GHz  and  31-  31.3  GHz  in  response  to  Resolution  145  (WRC-  03),  and  for  high  altitude  platform  stations  operating  in  the  bands  47.2-  47.5  GHz  and  47.9-  48.2  GHz  in  response 
 to  Resolution  122  (Rev.  WRC-  03);  ISSUE:  Identifying  a  common  300  MHz  segment  of  the  band  27.  5-  28.35  GHz,  paired  with  the  300  MHz 
 band  at  31-  31.  3  GHz,  for  use  by  HAPS  in  the  countries  listed  in  Nos.  5.537A  and  5.543A  or  countries  in  Region  2  planning  provisional  operation,  taking  into  account  the  requirements  of  other  fixed-  service 
 systems  and  other  services,  and  resolving  outstanding  future  conference  related  issues.  (i)  Resolution  145  (WRC-  03) 

 "Potential  use  of  the  bands  27.5-  27.8  GHz  and  31-  31.3  GHz  by  high  altitude  platform  stations  (HAPS)  in  the  fixed  service" 
 Background  Information: 
 Resolution  145:  WRC-  2000  decided  to  adopt  provisions  for  the  operation  of  HAPS  on  a  non-interfering/  non-  protected  basis  in  the  bands  27.5-  28.35  and  31-  31.3  GHz  in  Region  3,  but  did  not  allow 

 operation  in  the  entire  bands  until  studies  could  be  completed  to  determine  how  best  to  protect  existing  services  in  these  and  nearby  frequency  bands.  WRC-  03  further  refined  these  provisions  by  deciding  to 
 limit  HAPS  operation  to  300  MHz  in  a  specified  direction  in  each  of  these  two  bands,  retaining  the  requirement  for  HAPS  to  operate  on  a  non-  interfering/  non-  protected  basis  in  these  300  MHz  segments, 
 and  adopting  Resolution  145  (WRC-  03),  which  created  the  possibility  of  allowing  Region  2  administrations  to  advise  the  Radiocommunications  Bureau  of  their  intent  to  implement  HAPS  systems 
 within  the  bands  27.5-  28.35  and  31-  31.3  GHz.  Administrations  intending  to  implement  HAPS  in  these  bands  are  to  seek  the  explicit  agreement  of  concerned  administrations  in  accordance  with  resolves  4  of 
 this  Resolution.  Under  Resolution  145  (WRC-  03),  the  use  of  HAPS  within  the  fixed-  service  allocations  within  the  27.5- 
 28.35  GHz  and  31-  31.  3  GHz  bands  must  be  limited  to  300  MHz  in  each  band,  and  is  subject  to  the  condition  that  such  use  must  not  cause  harmful  interference  to,  nor  claim  protection  from,  other  stations 
 of  services  operating  in  accordance  with  the  Table  of  Frequency  Allocations  of  Article  5.  Furthermore,  the  Resolution  specifies  that  that  the  development  of  these  other  services  shall  proceed  without  constraints 
 by  HAPS  operating  pursuant  to  the  Resolution.  This  Resolution  also  calls  for  the  identification  of  a  common  300  MHz  within  the  27.5-  28.35  GHz  band  for  use  by  HAPS.  With  respect  to  the  band  31-  31.  3 
 GHz,  Resolution  145  (WRC-  03)  specifies  that  systems  using  HAPS  in  Region  2  in  the  band  31-  31.3  GHz  must  not  cause  harmful  interference  to  the  radio  astronomy  service  having  a  primary  allocation  in  the 
 band  31.  3-  31.8  GHz,  taking  into  account  the  protection  criterion  given  in  Recommendation  ITU-  R  RA.  769.  The  Resolution  contains  limits  on  the  level  of  unwanted  power  density  into  the  HAPS 
 ground  station  antenna  in  the  band  31.  3-  31.8  GHz  in  order  to  ensure  the  protection  of  satellite  passive  services.

 networks  in  the  FSS  within  the  band  27.5-  27.88.  35  GHz,  taking  into  account  Recommendation  ITU-  R  SF.  1601  for  the  situations  referred  to  in  considering  l); 
 4  to  study  the  regulatory  provisions  that  might  be  needed  in  order  to  address  those  cases  where  the  deployment  of  HAPS  in  the  fixed  service  in  the  bands  27.5-  28.35  GHz  and  31-  31.  3  GHz  in  the  territory 
 of  one  administration  may  affect  other  administrations;  35  to  continue  to  carry  out  studies  on  the  appropriate  interference  mitigation  techniques  for  the 
 situations  referred  to  in  considering  j),  invites  administrations, 
 to  advise  the  Radiocommunications  Bureau  of  their  intention  to  implement  HAPS  systems  within  the  band  27.  5-  27.88.  35  GHz  and  in  the  band  31-  31.3  GHz,  whether  in  countries  listed  in  Nos.  5.537A  and 
 5.543A  or  in  accordance  with  resolves  12,  and  to  specify  the  technical  characteristics  of  the  systems  they  intend  to  implement  frequency  bands  (up  to  300  MHz  each  with  the  27.5-  28.  35  GHz  and  31-  31.3  GHz 
 bands)  they  intend  to  use  for  such  systems,  instructs  the  Radiocommunications  Bureau, 
 to  publish  in  the  International  Frequency  Information  Circular  (BR  IFIC)  a  list  of  administrations  who  have  so  advised,  and  to  publish  the  information  on  HAPS  implementation  received  from  administrations 
 which  intend  to  implement  systems  using  HAPS  in  the  fixed  service  in  the  bands  27.5-  27.88.  35  GHz  and  31-  31.3  GHz. 
 Reason:  Changes  to  frequency  ranges  throughout,  deletion  of  invites  1,  and  other  minor  changes  are  consequential  to  proposal  USA/  1.8/  A.  Deletion  of  noting  is  made  recognizing  that  this  is  a  simple 
 statement  of  fact.  Deletion  of  invites  4  is  made  recognizing  the  retention  of  old  resolves  4,  now  resolves  3.  Changes  to  invites  administrations  are  proposed  to  clarify  that  administrations  are  to  supply  technical 
 details  of  their  systems  along  with  an  indication  of  their  intention  to  implement  HAPS  in  these  frequency  bands.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Agenda  Item  1.12:  to  consider  possible  changes  in  response  to  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference:  Advance  publication,  coordination,  notification  and 

 recording  procedures  for  frequency  assignments  pertaining  to  satellite  networks  in  accordance  with  Resolution  86  (WRC-  03); 

 Coordination  of  the  radionavigation-  satellite  service  (space-  to-  space)  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz 
 Background  Information:  The  scope  and  criteria  to  be  used  for  the  implementation  of  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference  by  future  world 
 radiocommunication  conferences  (WRCs)  is  established  in  Resolution  86  (WRC-  03).  Resolves  1  of  Resolution  86  (WRC-  03)  relates  to  the  consideration  of  proposals  dealing  with  deficiencies  in 
 the  advance  publication,  coordination  and  notification  procedures  of  the  Radio  Regulations  for  space  services,  and  Resolves  2  relates  to  consideration  of  proposals  intended  to  transform  the 
 content  of  the  Rules  of  Procedure  into  regulatory  text. 
 WRC-  2000  added  the  space-  to-  space  direction  to  the  existing  radionavigation-  satellite  service  (RNSS)  (space-  to-  Earth)  allocations  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz,  along 
 with  footnote  5.329A.  WRC-  03  added  footnote  5.328B,  which  applied  coordination  between  two  non-  GSO  RNSS  systems  and  between  non-  GSO  and  GSO  RNSS  systems  in  the  bands  1  164- 
 1  300  MHz,  1  559-  1  610  MHz  and  5  010-  5  030  MHz  under  Nos.  9.12,  9.12A  and  9.13  after  1  January  2005,  without  specifying  direction  (i.  e.,  space-  to-  Earth  or  space-  to-  space).  Coordination 
 between  GSO  RNSS  systems  in  the  same  bands  (space-  to-  Earth  and  space-  to-  space)  is  covered  by  No.  9.7,  again  without  specifying  direction  (i.  e.,  space-  to-  Earth  or  space-  to-  space). 

 No.  9.11A  applies  the  coordination  provisions  of  Nos.  9.12  to  9.16  where  the  requirement  to  coordinate  is  included  in  a  footnote  to  the  Table  of  Frequency  Allocations  referring  to  No. 
 9.11A.  Since  WRC-  2000,  the  Rules  of  Procedure  (RoP),  issued  by  the  Radio  Regulations  Board  (RRB),  rather  than  the  Radio  Regulations  have  defined  the  services  and  frequency  bands  for 
 which  the  coordination  procedure  under  No.  9.11A  is  required.  The  RRB  considered  the  application  of  No.  9.11A  to  the  bands  given  in  No.  5.329A  (i.  e.,  1  215-  1  300  and  1  559- 
 1  610  MHz  )  and  interpreted  the  Regulations  as  excluding  RNSS  (space-  to-  space)  assignments  in  the  bands  given  in  No.  5.329A  from  any  obligation  to  coordinate  with  other  services  and  with 
 RNSS  (space-  to-  Earth),  but  as  obliging  these  RNSS  (space-  to-  space)  assignments  to  coordinate  with  each  other. 

 In  addition,  many  RNSS  (space-  to-  space)  network  assignments  are  receive-  only  in  the  bands  1215-  1  300  MHz  and  1  559-  1  610  MHz.  Resolution  610  (WRC-  03),  as  referenced  in  No. 
 5.328B,  requires  administrations  to  provide  evidence  of  binding  agreements  for  the  manufacture, 
28
 29 
 procurement,  and  launch  of  RNSS  systems  and  networks.  This  resolution  was  intended  to  aid  bilateral  coordination  between  transmitting  RNSS  systems  and  networks  by  ensuring  such 
 systems  are  either  in  operation  or  in  the  process  of  being  implemented.  Requiring  Resolution  610  (WRC-  03)  data  for  receiving  space  stations  is  unnecessary. 

 Therefore,  modifications  to  No.  5.329A  and  No.  5.328B  are  needed  to  reflect  the  RRB  decision  that  requires  RNSS  (space-  to-  space)  to  coordinate  only  with  other  RNSS  (space-  to-  space)  but  not 
 with  other  services  or  with  RNSS  (space-  to-  Earth),  and  to  remove  Resolution  610  (WRC-  03)  obligations  from  RNSS  receiving  space  stations.  Additionally,  to  ensure  that  the  obligation  on 
 RNSS  (space-  to-  space)  networks  under  No.  5.329A  is  also  adequately  reflected  for  geostationary  RNSS  (space-  to-  space)  networks  with  respect  to  GSO  RNSS  (space-  to-  Earth)  networks  in  the 
 1215-  1300  MHz  and  1559-  1610  MHz  bands  (a  coordination  scenario  not  encompassed  by  Nos.  9.12,  9.12A,  and  9.13),  the  modification  to  No.  5.328B  refers  as  well  to  No.  9.7.

 Document  WAC/  100(  27.04.06): 
 Comments  of  IWG-  2  on  Draft  U.  S.  Proposal  from  Exec.  Branch  Agencies  on  WRC-  07  Agenda  Item  1.20  (Document  IWG-  2/  057) 

 IWG-  2  has  considered  the  satellite  elements  of  Document  IWG-  2/  057,  which  contains  draft  U.  S.  proposal  for  WRC-  07  Agenda  Item  1.20  from  the  Executive  Branch  agencies.  It  offers  the  following 
 comments: 
 1.  IWG-  2  endorses  the  NOC  proposals  for  the  bands  22.55-  23.55  GHz  and  30-  31  GHz  (inter-  satellite  service  and  fixed-  satellite  service  (Earth-  to-  space),  respectively)  that  are  contained  in  Proposals  USA/  /5 
 and  USA/  /7. 
 2.  IWG-  2  also  endorses  the  SUP  proposal  for  Resolution738  that  is  contained  in  Proposal  USA/  /13. 

 3.  IWG-  2  observes  that  it  is  premature  for  the  United  States  to  assert,  in  the  background  or  in  the  reasons  for  any  specific  proposal,  that  values  proposed  for  the  protection  of  the  EESS  (passive)  are  based  on  an 
 assessment  of  the  impact  on  the  relevant  active  service.  To  the  extent  that  any  ITU-  R  studies  have  even  considered  the  impact  on  the  active  service  involved    a  requirement  of  both  Resolution  738  (WRC-  03) 
 and  the  agenda  item    no  conclusions  have  yet  been  reached.  The  FSS  industry  is  continuing  to  address  this  question  with  respect  to  the  operation  of  earth  stations  in  the  47.2-  50.2  GHz  FSS  (Earth-  to-  space) 
 band. 
 4.  IWG-  2  is  concerned  with  the  proposal  for  mandatory  limits  on  FSS  earth  station  emissions  into  adjacent  bands.  For  protection  against  unacceptable  interference  caused  by  unwanted  emissions, 
 mandatory  limits  may  be  without  precedent  in  the  RRs.  The  language  in  the  Exec.  Branch  agencies  proposals  for  new  footnotes  (including  5.  BBB,  5.  DDD,  and  5.  EEE)  would  appear  to  invite  BR 
 examination  under  Art.  11  of  compliance  with  unwanted  emission  limits.  Even  if  BR  examination  is  not  what  the  Exec.  Branch  agencies  contemplate,  the  mandatory  nature  of  the  wording  does  not  clearly 
 exclude  examination,  and  has  serious  negative  implications  for  the  operation  and  evolution  of  advanced  services  in  the  affected  active  service  bands.  In  Document  WAC/  096,  a  redline  of  the  Exec.  Branch 
 agencies  proposal  for  Agenda  Item  1.20  (Doc.  IWG-  2/  057),  IWG-  2  offers  suggestions  for  the  wording  of  the  proposed  footnotes  that  aligns  the  notes  generally  with  the  approach  taken  by  WRC-  03  with  respect  to 
 protection  of  the  radioastronomy  service  from  detrimental  interference  (see  Resolution  739  (WRC-  03),  and  removes  any  suggestion  that  the  footnotes  would  subject  FSS  and  space  operations  earth  stations  to 
 BR  examination.  The  language  of  the  alternative  text  was  coordinated  with  IWG-  1,  which  has  responsibility  for  the  terrestrial  service  elements. 

 5.  With  respect  to  the  proposal  for  an  unwanted  emission  value  for  FSS  earth  stations  operating  in  the  47.2-  50.2  GHz  band  (proposed  note  5.  DDD  in  Proposal  USA/  /10),  it  appears  that  the  derivation  of  the 
 30  dBW/  200  MHz  level  that  is  stated  as  needed  to  protect  the  EESS  (passive)  from  unwanted  emissions  into  the  50.2-  50.4  GHz  band  may  have  been  based  on  unrealistic  assumptions  regarding  FSS  deployment 
 and  parameters.  Furthermore,  it  should  be  emphasized  in  the  proposal  that  the  protection  level  is  a  clear-sky  level,  and  that  FSS  earth  stations  in  the  47.2-  50.2  GHz  band  can  increase  their  transmit  power  density 
 by  TBD  dB,  to  overcome  fading  conditions  without  causing  additional  impact  to  the  EESS  (passive)  systems.  IWG-  2  emphasizes  that  it  has  no  difficulty  with  the  concept  of  identifying  an  unwanted 
30
 31 
 emission  level  that  would  protect  the  EESS  (passive)  service  in  that  band;  at  this  time,  however,  that  level  remains  under  discussion  between  interested  representatives  from  both  the  active  service  and  passive 
 service  communities. 
 6.  There  is  an  inconsistency  between  the  language  of  No.  5.  DDD  in  Proposal  USA/  /10  and  the  proposed  modification  to  Article  5  in  Proposal  USA/  /9.  The  former  indicates  that  the  note  is  to  apply  only  to  the 
 49.44-  50.2  GHz  portion  of  the  47.2-  50.2  GHz  band  in  Region  1,  while  the  latter  applies  No.  5.  DDD  to  the  entire  47.2-  50.  2  GHz  band.  IWG-  2  recommends  that  this  discrepancy  be  resolved,  but  as  long  as  No. 
 5.  DDD  reflects  a  satisfactory  resolution  of  the  matter  addressed  in  Comment  No.  4  above,  IWG-  2  takes  no  position  on  how  this  discrepancy  should  be  resolved.

 INFORMAL  WORKING  GROUP  3  (IWG-  3) 
 IMT-  2000  and  2.5  GHz  Sharing  Issues 

 Document  WAC/  101(  27.04.06): 
 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 WRC-  07  Agenda  Item  1.9:  to  review  the  technical,  operational  and  regulatory  provisions  applicable  to  the  use  of  the  band  2  500-  2  690  MHz  by  space  services  in  order  to  facilitate  sharing  with  current  and  future 
 terrestrial  services  without  placing  undue  constraint  on  the  services  to  which  the  band  is  allocated; 

 Background  Information:  The  band  2500-  2690  MHz  is  allocated  to  both  terrestrial  and  satellite  services  on  a  primary  basis.  The  terrestrial  services  include  the  Mobile  Services  and  the  Fixed  Services 
 (including  IMT-  2000).  Both  the  terrestrial  Mobile  and  Fixed  Services  have  been  rapidly  evolving  to  encompass  high-  speed  mobile  Internet  services  requiring  sensitive  receiving  equipment,  which  are  highly 
 susceptible  to  interference. 
 The  2500-  2690  MHz  band  is  also  allocated  to  the  satellite  services,  which  include  MSS  (including  GSO  and  non-  GSO),  BSS  (including  GSO  and  non-  GSO),  and  FSS.  In  WRC-  03  the  issue  of  sharing  between 
 terrestrial  services  and  NGSO  BSS  (Sound)  in  certain  Region  3  countries  was  resolved  with  the  revision  of  pfd  limits/  coordination  thresholds  for  NGSO  BSS  (Sound)  per  Resolution  539.  GSO  BSS  (Sound) 
 limits/  coordination  thresholds  within  these  countries  were  also  tightened  for  systems  for  which  complete  Appendix  4  coordination  information  has  been  received  after  1  June  2005.  Other  than  for  these  Region  3 
 countries  the  pfd  limits  for  BSS  remained  the  same  as  given  in  Table  21-  4. 
 In  general,  co-  frequency  sharing  between  the  mobile-  satellite  service  (MSS)  and  terrestrial  services  has  been  found  to  be  difficult  in  the  ITU-  R  studies.  The  sharing  between  the  terrestrial  services  and  the  MSS 
 poses  risks  of  harmful  interference  to  both  systems.  In  addition,  it  will  require  large  separation  distance  between  terrestrial  stations  and  MSS  earth  stations  in  order  to  avoid  harmful  interference  to  both  stations. 
 ITU-  R  Report  M.  2041  studied  the  feasibility  of  sharing  between  MSS  and  MS  for  IMT-  2000  and  highlighted  the  incompatibility  between  these  two  services  on  a  co-  frequency  basis. 

 Both  BSS  and  FSS  are  also  allocated  to  the  2500-  2690  MHz  band  and  are  subject  to  the  limits  in  Table  21-  4.  WRC-  03  recognized  the  potential  sharing  difficulty  between  the  terrestrial  and  satellite  services  and 
 caused  the  formation  of  Joint  Task  Group  6-  8-  9  to  study  the  issues  related  to  sharing. 
 JTG  6-  8-  9  has  developed  a  methodology  for  estimating  the  satellite  pfd  values  required  to  protect  terrestrial  services.  Based  on  this  methodology  the  USA  has  determined  that  pfd  values  at  the  surface  of 
 the  Earth  produced  by  the  emissions  of  MSS,  BSS  and  FSS  satellites  of  -136  dBW/  m  2  /MHz  for  angles  of  arrival  below  5  0  and  -122  dBW/  m  2  /MHz  for  angles  of  arrival  greater  than  25  0  would  yield  tolerable  levels 
 of  interference  to  the  Fixed  and  non  IMT-  2000  mobile  services. 

 There  are  definite  advantages  to  having  a  hard  limit  regulatory  regime,  based  on  the  specification  of  a  power  flux  density  mask  in  Article  21  of  the  Radio  Regulations.  First  it  would  ensure  the  long  term 
 safeguard  of  terrestrial  systems  in  the  band  2  500-  2  690  MHz  from  satellite  interference  and  could  also  be 
32
 33 
 beneficial  to  the  long-  term  development  of  space  services  as  a  defined  set  of  pfd  limits  would  be  known.  Additionally,  a  hard  limit  regime  would  result  in  no  need  for  coordination  between  administrations  with 
 terrestrial  services  and  administrations  planning  to  deploy  FSS,  MSS  or  BSS  systems. 
 However,  there  may  be  potential  disadvantages  to  the  hard  limit  regime  based  on  the  PFD  limits  that  are  ultimately  adopted  by  the  WRC  for  both  the  terrestrial  and  space  services.  The  PFD  limits  adopted  to 
 protect  terrestrial  networks  may  have  the  result  that  it  would  be  difficult  to  operate  satellite  networks  in  this  frequency  band.  Alternatively,  the  PFD  limits  adopted  may  have  the  result  that  it  would  be  difficult 
 to  operate  terrestrial  networks  in  this  frequency  band. 

 This  proposal  calls  for  assigning  the  above  pfd  values  for  MSS,  FSS  and  BSS  in  Article  21,  Table  21-  4,  in  order  to  provide  long  term  protection  of  terrestrial  services  in  this  band.

 Reasons:  Consequential  to  adding  pfd  limit  for  MSS  to  Article  21,  Table  21-  4  per  USA/  /1.  Limits  on  MSS  pfd  eliminate  the  need  for  coordination  with  terrestrial  systems  in  the  band  2

 Document  WAC/  102(  27.04.06): 
 To  the  WRC-  07  Advisory  Committee: 
 Attached  please  find  two  documents  from  IWG-  3  related  to  Agenda  Item  1.9  to  review  the  technical,  operational  and  regulatory  provisions  applicable  to  the  use  of  the  band  2  500-  2  690  MHz  by  space 
 services  in  order  to  facilitate  sharing  with  current  and  future  terrestrial  services  without  placing  undue  constraint  on  the  services  to  which  the  band  is  allocated  of  the  2007  to  the  World  Radiocommunication 
 Conference  (WRC-  07). 
 After  considerable  debate,  IWG-  3  drafted  IWG-  3  Proposal  for  Agenda  Item  1.9  presented  in  Document  WAC/  102A.  Over  the  past  several  months,  this  document  was  reviewed  by  the  entire  IWG-  3  and 
 modified  to  include  the  concerns  of  some  MSS  companies,  including  New  ICO,  Globalstar  and  MSV.  The  majority  of  IWG-  3  members  supported  the  resulting  proposal.  However,  IWG-  3  was  unable  to  reach  full 
 consensus  as  a  minority  of  members  from  the  satellite  community  continued  to  object  to  the  proposal. 
 The  dissenting  proposal  from  the  satellite  community  is  contained  in  Proposal  Document  WAC/  102B.  This  document  was  not  extensively  reviewed  by  the  IWG  and  only  represents  the  views  of  those  parties 
 dissenting. 
 IWG-  3  forwards  the  majority  proposal  and  dissenting  proposal  to  the  WRC-  07  Advisory  Committee  for  its  consideration. 

 IWG-  3  forwards  the  majority  proposal  and  dissenting  proposal  to  the  WRC-  07  Advisory  Committee  for  its  consideration.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 WRC-  07  Agenda  Item  1.9:  to  review  the  technical,  operational  and  regulatory  provisions  applicable  to  the  use  of  the  band  2  500-  2  690  MHz  by  space  services  in  order  to  facilitate  sharing  with  current  and 
 future  terrestrial  services  without  placing  undue  constraint  on  the  services  to  which  the  band  is  allocated; 

 Background  Information:  The  band  2  500-  2  690  MHz  is  allocated  for  sharing  by  both  terrestrial  and  satellite  services.  The  terrestrial  services  include  the  Mobile  Services  and  the  Fixed  Services 
 (including  IMT-  2000).  Both  the  terrestrial  Mobile  and  Fixed  Services  have  been  rapidly  evolving  to  encompass  high-  speed  mobile  Internet  services  requiring  sensitive  receiving  equipment,  which 
 are  highly  susceptible  to  interference. 
 Portions  of  the  2500-  2690  MHz  band  are  also  allocated  to  the  satellite  services,  which  include  MSS,  BSS  (including  GSO  and  non-  GSO),  and  FSS.  At  WRC-  03  the  issue  of  sharing  between 

 terrestrial  services  and  NGSO  BSS  (Sound)  in  certain  Region  3  countries  was  resolved  with  the  revision  of  pfd  limits  for  NGSO  BSS  (Sound)  per  Resolution  539.  GSO  BSS  (Sound)  limits  within 
 these  countries  were  also  tightened  for  systems  for  which  complete  Appendix  4  coordination  information  has  been  received  after  1  June  2005.  Other  than  for  these  Region  3  countries  the  BSS 
 limits  remained  the  same  as  given  in  Table  21-  4. 
 In  general,  co-  frequency  sharing  between  the  mobile-  satellite  service  (MSS)  and  terrestrial  services  has  been  found  to  be  difficult  in  the  ITU-  R  studies.  The  sharing  between  the  terrestrial 

 services  and  the  MSS  poses  risks  of  harmful  interference  to  both  systems.  In  addition,  sharing  would  require  large  separation  distances  between  terrestrial  stations  and  MSS  earth  stations  in 
 order  to  avoid  harmful  interference  to  both  stations.  ITU-  R  Report  M.  2041  studied  the  feasibility  of  sharing  between  MSS  and  MS  for  IMT-  2000  and  highlighted  the  sharing  difficulties  between 
 these  two  services  on  a  co-  frequency,  co-  coverage  basis.  Per  Report  M.  2041,  When  considering  the  sharing  of  the  same  frequency  band  between  the  terrestrial  component  of  IMT-  2000  and  the 
 MSS,  the  detailed  analysis  (see  Annex  2)  shows  that  such  sharing  is  not  feasible  over  the  same  geographical  area.  Consequently,  Radiocommunication  Study  Group  8  came  to  the  conclusion  that 
 co-  frequency  sharing  is  not  feasible  for  networks  operating  in  the  same  geographical  area.  Report  M.  2041  was  approved  in  SG8  with  support  from  the  USA. 

 Within  Region  2  any  satellite  service  launched  will  naturally  overlap  many  other  Region  2  countries  and  may  have  the  effect  of  interfering  with  existing  and  planned  terrestrial  services 
 within  that  band.  Administrations  in  Region  2  have  indicated  no  plans  to  implement  MSS  systems  in  the  2500-  2690  MHz  band.  A  number  of  Administrations  in  Region  2  have  authorized  terrestrial 
 Mobile  and  Fixed  services  and  several  other  Region  2  Administrations  have  definite  plans  to  introduce  new  terrestrial  Mobile  and  Fixed  services  in  the  2500-  2690  MHz  band.  (See  WP-  8F 
 questionnaire  to  administrations  and  summary  in  document  8F/  TEMP/  276). 
37

 In  addition  to  the  allocation  of  the  2500-  2520  MHz  and  2670-  2690  MHz  band  for  MSS  within  Region  2,  the  bands  137-  137.025  MHz,  148-  150.05  MHz,  399.9-  401  MHz,  406-  406.1  MHz,  455- 
 456  MHz,  459-  460  MHz,  1518-  1559  MHz,  1610-  1660.5  MHz,  1668.4-  1675  MHz,  1930-  1970  MHz,  1980-  2025  MHz,  2120-  2200  MHz,  2483.5-  2500  MHz,  14-  14.5  GHz,  19.7-  21.2  GHz,  29.5- 
 31  GHz,  39.5-  41  GHz,  among  others,  are  also  allocated  for  MSS  within  Region  2. 
 Considering  that:  (1)  Administrations  in  Region  2  have  indicated  no  plans  to  implement  MSS  services  in  the  2500- 
 2690  MHz  band,  (2)  Administrations  in  Region  2  have  implemented  or  plan  to  implement  terrestrial  Mobile  and 
 Fixed  services  in  the  2500-  2690  MHz  band,  (3)  Co-  frequency  sharing  of  the  2500-  2690  MHz  band  between  MSS  and  terrestrial  services 
 threatens  to  cause  interference  to  terrestrial  Mobile  services  systems,  (4)  That  there  is  other  spectrum  allocated  for  MSS  within  Region  2,  (I  move  to  strike  considering 

 the  MSS  allocation  in  Region  2  should  be  suppressed

 .  Reasons:  Co-  frequency,  co-  coverage  sharing  between  MSS  and  terrestrial  Mobile  services  is  not 
 possible  per  ITU-  R  Report  M.  2041.  As  stated  in  M.  2041,  When  considering  the  sharing  of  the  same  frequency  band  between  the  terrestrial  component  of  IMT-  2000  and  the  MSS,  the  detailed 
 analysis  (see  Annex  2)  shows  that  such  sharing  is  not  feasible  over  the  same  geographical  area.  Consequently,  Radiocommunication  Study  Group  8  came  to  the  conclusion  that  co-  frequency 
 sharing  is  not  feasible  for  networks  operating  in  the  same  geographical  area.  Administrations  in  Region  2  have  indicated  no  plans  to  implement  MSS  systems  in  the  2500-  2690 
 MHz  band.  A  number  of  Administrations  in  Region  2  have  authorized  terrestrial  Mobile  and  Fixed  services  and  several  other  Region  2  Administrations  have  definite  plans  to  introduce  new 
 terrestrial  Mobile  and  Fixed  services  in  the  2500-  2690  MHz  band.  (See  WP-  8F  questionnaire  to  administrations  and  summary  in  document  8F/  TEMP/  276).  Considering  that: 
 (1)  Administrations  in  Region  2  have  indicated  no  plans  to  implement  MSS  networks  in  the  2500-  2690  MHz  band, 
 (2)  Administrations  in  Region  2  have  implemented  or  plan  to  implement  terrestrial  Mobile  and  Fixed  services  in  the  2500-  2690  MHz  band, 
 (3)  Co-  frequency  sharing  at  2500-  2690  MHz  between  MSS  and  terrestrial  services  threatens  to  cause  interference  to  terrestrial  Mobile  services  systems. 
 (4)  That  there  is  other  spectrum  allocated  for  MSS  within  Region  2 
 the  MSS  allocation  in  Region  2  is  suppressed.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 WRC-  07  Agenda  Item  1.9:  to  review  the  technical,  operational  and  regulatory  provisions  applicable  to  the  use  of  the  band  2  500-  2  690  MHz  by  space  services  in  order  to  facilitate  sharing  with  current 
 and  future  terrestrial  services  without  placing  undue  constraint  on  the  services  to  which  the  band  is  allocated; 

 Background  Information:  The  band  2  500-  2  690  MHz  is  allocated  on  a  Primary  basis  to  both  terrestrial  and  satellite  services.  The  terrestrial  services  include  the  Mobile  Services  and  the 
 Fixed  Services  (including  IMT-  2000).  Both  the  terrestrial  Mobile  and  Fixed  Services  have  been  rapidly  evolving  to  encompass  high-  speed  mobile  Internet  services  requiring  sensitive  receiving 
 equipment,  which  are  highly  susceptible  to  interference. 
 Portions  of  the  2500-  2690  MHz  band  are  also  allocated  to  satellite  services,  which  include  MSS,  BSS  (including  GSO  and  non-  GSO),  and  FSS.  The  bands  2500-  2520  MHz  and  2670-  2690  MHz 

 are  allocated  to  the  MSS  on  a  Primary  basis  and  have  been  identified  for  use  by  the  satellite  component  of  IMT-  2000  and  beyond.  As  part  of  this  identification,  it  was  noted  that,  in  the 
 long  term  these  bands  might  also  be  used  for  the  terrestrial  component  of  IMT-  2000  and  beyond  (See  Res.  225). 

 At  WRC-  03  the  issue  of  sharing  between  terrestrial  services  and  NGSO  BSS  (Sound)  in  certain  Region  3  countries  was  resolved  with  the  revision  of  pfd  limits  for  NGSO  BSS  (Sound)  per 
 Resolution  539.  GSO  BSS  (Sound)  limits  within  these  countries  were  also  tightened  for  systems  for  which  complete  Appendix  4  coordination  information  has  been  received  after  1  June  2005. 
 Other  than  for  these  Region  3  countries  the  BSS  limits  remained  the  same  as  given  in  Table  21-  4. 
 In  general,  co-  frequency  sharing  between  the  mobile-  satellite  service  (MSS)  and  terrestrial  services  has  been  found  to  be  difficult  in  the  ITU-  R  studies.  The  sharing  between  the  terrestrial 

 services  and  the  MSS  poses  risks  of  harmful  interference  to  both  systems.  In  addition,  sharing  would  require  large  separation  distances  between  terrestrial  stations  and  MSS  earth  stations  in 
 order  to  avoid  harmful  interference  to  both  Services. 
 Large  separation  distances  could  be  available  in  large  countries  where  citizens  without  the  benefit  of  terrestrial  infrastructure  could  rely  on  MSS  systems  to  provide  vital  communications 

 services  including  Internet  access.  The  lack  of  terrestrial  infrastructure  in  developing  countries  and  sparsely  populated  areas  also  points  up  the  need  for  Services  such  as  the  MSS. 

 ITU-  R  Report  M.  2041  studied  the  feasibility  of  sharing  between  MSS  and  MS  for  IMT-  2000  and  highlighted  the  sharing  difficulties  between  these  two  services  on  a  co-  frequency,  co-  coverage 
 basis.  Report  M.  2041,  came  to  the  conclusion  that  sharing  is  not  feasible  over  the  same  geographical  area.  Consequently,  Radiocommunication  Study  Group  8  came  to  the  conclusion 
43
 44 
 that  co-  frequency  sharing  is  not  feasible  for  networks  operating  in  the  same  geographical  area,  even  though  Report  M.  2041  was  never  vetted  by  ITU-  R  Working  Party  8D. 
 Within  Region  2,  the  2005  hurricane  season  was  marked  by  massive  destruction  that  included  terrestrial  communications  infrastructure.  Entire  regions  in  the  states  of  Florida,  Alabama, 
 Mississippi,  Louisiana  and  Texas  were  laid  waste  by  hurricanes  Katrina  and  Rita.  MSS  systems  provided  lifesaving  communications  for  first  responders  and  government  agencies  over  wide 
 spread  areas  where  there  were  no  terrestrial  means.  Had  government  officials  availed  themselves  of  MSS  communications  equipment  before  the  storms  and  equipped  their  first  responders 
 continuity  of  emergency  communications  could  have  been  maintained.  Plans  have  been  announced  for  first  responders  to  be  equipped  with  MSS  equipment  to  provide  alternative 
 communications  when  terrestrial  means  fail.  As  much  of  Region  2  is  prone  to  tropical  storms,  other  countries  may  wish  to  follow  the  example  of  the  USA  and  equip  emergency  personnel  with 
 MSS  equipment. 
 In  view  of  the  outstanding  performance  provided  by  MSS  systems  during  the  past  hurricane  season,  it  seems  foolhardy  to  advocate  the  complete  elimination  of  an  allocation  for  this  Service 
 in  Region  2.  Allocation  to  the  MSS  on  a  Secondary  basis  would  provide  a  regulatory  solution  to  interference  while  still  maintaining  the  option  of  the  MSS  in  areas  where  no  terrestrial 
 infrastructure  exists.

 of  both  terrestrial  Services  and  the  MSS. 
 Allocation  to  the  MSS  on  a  Secondary  basis  would  provide  a  regulatory  solution  to  interference  while  still  maintaining  the  option  of  the  MSS  in  areas  where  no  terrestrial  infrastructure  exists.

 Reasons:  In  general,  co-  frequency  sharing  between  the  mobile-  satellite  service  (MSS)  and  terrestrial  services  has  been  found  to  be  difficult  in  the  ITU-  R  studies.  The  sharing  between  the 
 terrestrial  services  and  the  MSS  poses  risks  of  harmful  interference  to  both  systems.  In  addition,  sharing  would  require  large  separation  distances  between  terrestrial  stations  and  MSS  earth 
 stations  in  order  to  avoid  harmful  interference  to  both  Services. 
 Large  separation  distances  could  be  available  in  large  countries  where  citizens  without  the  benefit  of  terrestrial  infrastructure  could  rely  on  MSS  systems  to  provide  vital  communications 

 services  including  Internet  access.  The  lack  of  terrestrial  infrastructure  in  developing  countries  and  sparsely  populated  areas  also  points  up  the  need  for  Services  like  MSS.  The  use  of  large 
 separation  distances  could  permit  the  use  of  both  terrestrial  Services  and  the  MSS. 
 Allocation  to  the  MSS  on  a  Secondary  basis  would  provide  a  regulatory  solution  to  interference  while  still  maintaining  the  option  of  the  MSS  in  areas  where  no  terrestrial  infrastructure  exists.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 WRC-  07  Agenda  Item  1.11 
 Subject:  Modification  and  Augmentation  to  CITEL  PCC.  II  IAP  for  WRC-  07  Agenda  Item  1.11,  to  review  sharing  criteria  and  regulatory  provisions  for  protection  of  terrestrial  services  in  particular 
 terrestrial  television  broadcasting  services,  in  the  band  620    790  MHz  from  BSS  networks  and  systems,  in  accordance  with  Res.  545  (WRC-  03) 
 Purpose:  The  sixth  meeting  of  CITEL  PCC.  II  developed  an  IAP  for  WRC-  07  Agenda  Item  1.11,  to  which 

 the  US  signed.  The  US  strongly  supports  the  goal  of  this  IAP,  to  protect  terrestrial  services  in  the  620-  790  MHz  band  from  harmful  interference  of  transmitting  co-  frequency  broadcast-satellite 
 systems.  In  order  to  ensure  the  best  protection  of  terrestrial  systems,  the  US  believes  that  certain  modifications  are  needed  to  augment  the  proposal.  These  modifications, 
 summarized  in  the  following  paragraphs,  are  provided  in  the  attached  edits  to  the  IAP.  The  current  IAP,  which  specifies  NOC  to  Articles  5,  9,  and  11  of  the  Radio  Regulations,  needs 
 to  be  slightly  modified  because  the  Art.  5  provision  dealing  with  the  620-  790  MHz  BSS  allocation,  No.  5.311,  does  not  indicate  a  reference  bandwidth  for  the  pfd.  One  is  needed  to 
 avoid  questions  over  the  level  of  protection  afforded  to  terrestrial  services.  Furthermore,  Res.  545,  the  companion  resolution  to  this  agenda  item,  should  be  modified  to  reflect  that  studies  on 
 this  topic  are  completed  and  to  address  transitional  measures  (e.  g.,  how  the  Bureau  should  process  the  BSS  submissions  suspended  by  WRC-  03). 
 In  order  to  define  an  appropriate  reference  bandwidth  for  the  pfd,  it  is  assumed  that  the  reference  bandwidth  for  the  current  pfd  is  24  MHz,  recognizing  that  the  larger  the  bandwidth  assumed  for 
 a  given  pfd  value,  the  greater  protection  provided  to  terrestrial  services.  Then,  to  protect  broadcast  systems  and  more  narrowband  systems,  the  pfd  is  translated  into  a  4  kHz  bandwidth. 
 Summary:  The  following  pages  indicate  the  modification  to  the  IAP  for  agenda  item  1.11  in 
 strikethrough/  underline  format.

 INTER-  AMERICAN  PROPOSALS  OF  WSG-  2  (Item  on  the  Agenda:  4.1  ) 
 (Document  submitted  by  working  sub-  group  2  (WSG-  2)  ) 
 Agenda  Item  1.11:  to  review  sharing  criteria  and  regulatory  provisions  for  protection  of  terrestrial  services  in  particular  terrestrial  television  broadcasting  services,  in  the  band  620    790  MHz  from  BSS 
 networks  and  systems,  in  accordance  with  Resolution  545  (WRC-  03)  Background 

 Under  footnote  No.  5.311,  the  band  620-  790  MHz  may  be  used  for  assignments  to  television  stations  using  frequency  modulation  in  the  BSS  (GSO  or  non-  GSO).  Since  this  band  is  extensively  used  by  terrestrial 
 applications,  Recommendation  705  (WARC-  79)  includes,  among  other  things,  satellite  pfd  limits  needed  to  protect  the  terrestrial  services,  in  particular,  the  terrestrial  television  broadcasting  service  that  uses  this  band 
 extensively  in  all  three  Regions..  It  should  also  be  noted  that  there  are  allocations  to  the  fixed  and  mobile  services  in  some  regions  in  this  band  that  also  need  to  be  addressed.  In  particular,  some  Region  2 
 administrations  added  their  names  to  footnote  No.  5.  293  which  allocates  the  band  to  the  fixed  and  mobile  services  on  a  primary  basis  in  several  Region  2  countries. 

 In  Region  2  the  620-  790  MHz  band  is  used  extensively  by  free-  to-  air  TV  systems.  As  a  result  of  this  extensive  use  of  the  620-  790MHz  band  ,Region  2  Administrations  have  not  made  allowances  for  external 
 interference  in  the  deployment  of  their  terrestrial  TV  systems  or  in  the  development  of  their  TV  allotment  plans  or  in  the  development  of  other  fixed  and  mobile  services  and  therefore  ,there  are  no  excess  margins 
 which  could  have  been  used  to  accommodate  additional  interference  from  systems  in  the  BSS.  WRC-  03  adopted  a  freeze  on  the  processing  of  BSS  satellite  filings  in  the  band  until  the  next  WRC  as  per  a 
 new  Resolution  545  (WRC-  03)  and  suspended  the  application  of  No.  5.311  and  Recommendation  705  (WARC-  79)  until  that  date.  The  Resolution  was  acceptable  to  all  parties  with  the  understanding: 
 1)  it  allows  for  studies  to  continue  on  the  appropriate  protection  levels  for  the  terrestrial  broadcasting  service  (BS)  to  be  determined; 
 2)  it  does  not  impact  the  Regional  Planning  Conference  (RRC-  04/  06,  Region  2  is  not  affected)  for  these  services; 
 3)  it  places  a  moratorium  on  further  deployments  of  BSS  networks  in  these  bands  until  such  studies  are  complete. 
 This  proposal  effects  modifications  to  No.  5.311  and  Res.  545  that  ensure  the  complete  protection  of  the  current  and  future  usage  of  the  broadcast,  mobile,  and  fixed  services  in  the  620-  790  MHz  band  from 
 interference  from  broadcast  satellite  operations  in  this  same  band.  The  purpose  of  this  propose  is  to  restrict  the  future  deployment  of  broadcast  satellite  systems  in  a  band  that  is  very  extensively  used  by  terrestrial 
 services. 
49
 50 
 Since  neither  No.  5.311  nor  Rec.  705  indicate  a  reference  bandwidth  for  the  BSS  pfd  limit  in  620-  790  MHz  band,  a  reference  bandwidth  of  24  MHz  is  assumed  and  then  translated  further  to  a 
 4  kHz  bandwidth,  and  No.  5.311  is  accordingly  modified.  Res.  545  from  WRC_  03  is  modified  to  address  transitional  issues  related  to  resuming  processing  of  BSS  networks  after  WRC-  03 
 suspended  such  processing  by  the  BR. 
 As  a  consequence,  Rec.  705,  Criteria  to  be  applied  for  frequency  sharing  between  the  broadcasting-  satellite  service  and  the  terrestrial  broadcasting  service  in  the  band  620-  790  MHz, 

 is  deleted  since  its  relevant  content,  the  pfd  limit  reference,  is  contained  in  the  modifications  to  No.  5.311  and  Res.  545,  and  after  WRC-  07  the  broadcast  satellite  and  terrestrial  broadcast  issues 
 in  this  band  will  have  been  resolved. 

 MOD  5.311  Within  the  frequency  band  620-  790  MHz,  assignments  may  be  made  to  television  stations  using  analog  frequency  modulation  in  the  broadcasting-  satellite  service 
 subject  to  agreement  between  the  administrations  concerned  and  those  having  services,  operating  in  accordance  with  the  Table,  which  may  be  affected  (see  Resolutions  33  (Rev.  WRC-  03)  and 
 507  (Rev.  WRC-  03)).  Such  stations  shall  not  produce  a  power  flux-  density  in  excess  of  the  value  129  166.8  dB(  W/  m  2  /  4  kHz)  for  all  angles  of  arrival  less  than  20  (see  Recommendation  705) 
 within  the  territories  of  other  countries  without  the  consent  of  the  administrations  of  those  countries.  Resolution  545  (WRC-  0307)  applies.  (WRC--  0307) 

 MOD  Res.  545  (See  Attachment  1) 
 SUP  Rec.  705 

 Reason 
 Region  2  administrations  have  no  plans  to  implement  BSS  systems  in  the  band  620-  790  MHz.  The  administrations  in  Region  2  are  currently  operating  or  planning  to  operate  a  large  number  of  terrestrial 
 analog  and  digital  television  broadcasting  systems.  In  addition,  some  Region  2  administrations  will  be  implementing  mobile  and  fixed  services,  including  public  safety  applications.  As  a  result  of  this 
 extensive  use  of  the  620-  720MHz  by  existing  systems  ,Region  2  Administrations  have  not  allocated  any  additional  interference  margins  for  the  protection  of  terrestrial  TV  broadcasting  and  therefore  any 
 additional  interference  from  BSS  will  place  undue  constraints  on  the  existing  and  planned  services  in  Region  2.

 considering 
 a)  that  No.  5.311  provides  the  conditions  under  which  the  band  620-  790  MHz  may  be  used  for  assignments  to  television  stations  using  analog  frequency  modulation  in  the  broadcasting-satellite 

 service  (BSS); 
 b)  that  it  is  necessary  to  adequately  protect  terrestrial  services  including  the  terrestrial  television  broadcasting  systems  and  fixed  and  mobile  systems  in  this  band; 

 c)  that  the  sharing  and  associated  provisions  for  satellite  networks  are  under  study  in  ITU-  R  with  respect  to  the  impact  of  such  systems  on  the  terrestrial  services; 
 cd)  that  geostationary-  satellite  (GSO)  BSS  networks  and  non-  geostationary  (non-  GSO)  BSS  satellite  networks  or  systems  are  at  the  stage  of  advance  publication  or  coordination,  or  have 
 been  notified  in  the  620-  790  MHz  frequency  band; 
 ed)  that  studies  are  being  undertaken  to  determine,  inter  alia,  the  planning  criteria  to  be  used  for  the  Regional  Radiocommunication  Conference  (RRC-  04/  05)  effected  a  terrestrial  digital 

 television  broadcasting  plan  for  Region  1  and  one  country  in  Region  3;  that  the  impact  of  these  GSO  BSS  networks  and  non-  GSO  BSS  satellite  networks  or  systems  on  terrestrial  services 
 including  digital  and  analogue  television  broadcasting  systems  has  yet  to  be  examined; 
 eg)  that  there  are  at  present  few  GSO  networks  operating  in  accordance  with  No.  5.31h)  that  it  would  be  inappropriate  to  draw  any  conclusions  regarding  the  form  and  levels  of 

 the  protection  criteria  and  their  application  to  GSO  BSS  networks  and  non-  GSO  BSS  satellite  networks  or  systems  until  the  completion  of  relevant  studies  and  the  approval  of  corresponding 
 ITU-  R  Recommendations; 
 fi)  that  many  administrations  have  extensive  infrastructure  for  the  transmission  and  reception  of  analogue  and  digital  television  services  between  620  MHz  and  790  MHz, 

 g)  that  some  administrations  are  using  or  plan  to  use  portions  of  the  620-  790  MHz  band  for  fixed  and  mobile  service  applications 
 noting 
 a)  that  the  protection  of  terrestrial  television  services  in  the  band  620-  790  MHz  requires  more  study  before  any  conclusion  can  be  made  about  the  appropriate  pfd  values; 

 b)  that  studies  called  for  in  Recommendation  705  have  been  recently  initiated  but  not  completed; 
 c)  that  the  reference  bandwidth  of  the  pfd  limit  in  No.  5.311  is  undefined  and  guidance  is  urgently  needed  and  has  been  requested  by  the  Radiocommunication  Bureau; 
 d)  that  the  existing  provisions  related  to  the  band  620-  790  MHz  are  ambiguous  and  have  been  difficult  to  apply  by  administrations  and  the  Bureau,  that  WRC-  03  suspended  processing  of 
51
 52 
 submissions  of  BSS  networks  or  systems  in  the  620-  790  MHz  band,  irrespective  of  their  date  of  receipt,  pending  WRC-  07  decisions; 
 b)  that  WRC-  03  specified  that  GSO  BSS  networks  and  non-  GSO  BSS  satellite  networks  or  systems  in  the  frequency  band  620-  790  MHz  other  than  those  notified,  brought  into  use  and  the 
 date  of  bringing  into  use  confirmed  before  the  end  of  WRC-  03,  shall  not  be  brought  into  use  before  the  end  of  WRC-  07; 

 c)  that  transitional  measures  are  needed  to  address  the  WRC-  03  decisions  in  notings  a)  and  b), 
 resolves 
 1  that,  at  the  end  of  WRC-  07,  the  processing  of  submissions  of  GSO  BSS  networks  and  non-  GSO  BSS  satellite  networks  or  systems  in  the  frequency  band  620-  790  MHz  received  by  the 

 Bureau  and  not  brought  into  use  prior  to  5  July  2003,  irrespective  of  their  date  of  receipt,  shall  be  suspended  pending  WRC-  07  decisions  on  the  sharing  criteria,  including  the  pfd  required  to 
 protect  the  terrestrial  services  in  this  frequency  bandshall  resume,  with  No.  5.311  as  revised  by  WRC-  07  applied;

 subject  to  the  procedures  to  be  decided  at  WRC-  07, 
 invites  ITU-  R 
 to  conduct  studies  as  a  matter  of  urgency,  and  develop  sharing  criteria  and  regulatory  provisions,  prior  to  WRC-  07,  for  the  protection  of  terrestrial  services,  in  particular  terrestrial  television 

 broadcasting  services,  in  the  620-  790  MHz  band  from  GSO  BSS  networks  and  non-  GSO  BSS  satellite  networks  or  systems  which  it  is  planned  to  operate  in  this  band, 

 instructs  the  Director  of  the  Radiocommunication  Bureau 
 subject  to  the  decisions  taken  by  WRC-  07,  to  resume,  as  appropriate,  the  application  of  Nos.  5.311  (as  revised  by  WRC-  07),  9.34  and  11.30  and  other  relevant  associated 

 provisions  of  the  Radio  Regulations,.  instructs  the  Secretary-  General

 From:  Chairman  &  Vice  Chairman,  IWG-  4  To:  Chair,  FCC  WAC-  2007  Board 
 Subject:  Non-  census  on  Agenda  Item  1.13 
 IWG-  4  has  held  13  meetings  since  its  inception,  about  10  of  these  included  extensive  work  and  discussion  as  it  pertains  to  ITU-  R  Res.  544  (WRC-  03)  portion  for  WRC-  07  Agenda  Item  1.13 

 taking  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  MHz  and  10  MHz,  excluding  those 
 allocations  to  services  in  the  frequency  range  7  000  -7  200  kHz  and  those  bands  whose  allotment  plans  are  in  Appendices  25,  26  and  27  and  whose  channeling  arrangements  are  in 
 Appendix  17,  taking  account  of  the  impact  of  new  modulation  techniques,  adaptive  control  techniques  and  the  spectrum  requirements  for  HF  broadcasting 

 Following  considerable  discussion  on  the  pros  and  cons  of  each  proposal,  the  two  major  factions,  the  National  Association  of  Shortwave  Broadcasters  (NASB)  and  Globewireless,  Inc.(  with  a  number  of  other 
 non-  government  HF  users  of  the  Fixed  and  Mobile  Services  bands),  could  not  reach  agreement  on  one  proposal.  There  was  no  compromise  or  consensus. 

 Several  participants  suggested  different  options  and  their  impact  on  what  might  likely  result  at  WRC-  07.  There  was  no  compromise.  The  IWG-  4  decided  that  the  two  alternative  draft  proposals  should  be  sent  to 
 the  WAC  for  its  consideration  and  action.  These  alternative  proposals  are  presented  in  WAC/  104A  and  WAC/  104B.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 AGENDA  ITEM  1.13  OF  WRC-  07 
 Agenda  Item  1.13:  taking  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  MHz 
 and  10  MHz,  excluding  those  allocations  to  services  in  the  frequency  range  7  000-  7  200  kHz  and  those  bands  whose  allotment  plans  are  in  Appendices  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  the  spectrum  requirements  for 
 HF  broadcasting: 
 The  essence  of  each  of  the  3  Resolutions  mentioned  in  the  Agenda  Item  follows: 
 a.  Resolution  351  WRC-  03)  asks  that,  as  soon  as  ITU-  R  studies  are  completed,  a  future  competent  conference  should  consider  necessary  changes  to  Appendix  17 
 to  enable  the  use  of  new  technology  by  the  maritime  mobile  service, 
 b.  Resolution  544  (WRC-  03)  asks  to  consider  additional  allocations  in  the  HF  bands  between  4  and  10  MHz  to  the  broadcasting  service,  taking  into  account  its 
 requirements  and  the  interest  of  all  affected  services,  with  a  noting  that  the  following  bands  are  preferred  by  the  broadcasting  service  for  possible  additional 
 allocations  to  it: 
 4  500-  4  650  kHz  5  060-  5  250  kHz 
 5  840-  5  900  kHz  7  350-  7  650  kHz

 Background  information: 
 This  is  a  very  broad  agenda  item,  as  there  are  multiple  services  allocated  to  the  HF  bands  between  4  MHz  and  10  MHz,  including  aeronautical  mobile  (OR),  aeronautical  mobile 
 (R),  amateur,  broadcasting,  fixed,  maritime  mobile,  land  mobile  and  mobile  services.  The  3  Resolutions  noted  above  deal  with  3  separate  issues,  though  the  agenda  item  itself 
 connects  the  services  through  the  consideration  of  modifying  the  allocations  within  these  6  MHz.  The  CPM  convened  immediately  following  WRC-  03  and  assigned  the  primary 
 responsibilities  for  the  separate  issues  (based  upon  each  Resolution)  to  different  ITU-  R  Study  Group  Working  Parties.  Subsequently  a  joint  arrangement  has  been  made  to 
 facilitate  the  production  of  a  CPM  Report  on  the  full  consequences  of  the  Agenda  Item,  including  the  overlap  engendered  by  the  reallocation  element. 

 Resolution  351: 
 resolves 
 1)  that,  in  order  to  provide  full  worldwide  interoperability  of  equipment  on  ships,  there  should  be  one  technology,  or  more  than  one  interoperable 

 worldwide  technology,  implemented  under  Appendix  17; 
 2)  that,  as  soon  as  the  ITU-  R  studies  are  completed,  a  future  competent  conference  should  consider  necessary  changes  to  Appendix  17  to  enable  the  use  of 

 new  technology  by  the  MMS; 
 The  focus  of  Resolution  351  (WRC-  03)  is  to  identify  a  digital  technology,  or  family  of  digital  technologies,  that  provide  interoperability  and  improved  usage  of  the  MF  and  HF 

 bands  allocated  to  the  maritime  mobile  service  under  Appendix  17.  The  scope  of  this  portion  of  the  agenda  item  includes  a  review  of  all  Appendix  17  assignments  to  facilitate 
 the  introduction  of  these  advanced  maritime  mobile  digital  systems. 
 Resolution  351  (WRC-  03)  calls  for  studies  to  include:  future  requirements  of  the  MMS,  technical  characteristics  of  the  digital  systems,  the  necessary  modifications  to 

 Appendix  17  to  enable  the  use  of  new  technologies  by  MMS,  a  timetable  for  the  introduction  of  new  digital  technologies,  and  recommendations  on  how  digital 
 technologies  can  be  introduced  while  ensuring  compliance  with  distress  and  safety  requirements.  In  accordance  with  resolves  2  of  Resolution  351,  as  soon  as  the  ITU-  R 
 studies  are  completed,  a  competent  conference  should  consider  necessary  changes  to  Appendix  17,  to  enable  the  use  of  new  digital  maritime  technologies  by  the  MMS.  These 
 studies  are  still  underway  and  should  be  refined  to  examine  the  requirements  of  GMDSS  electronic  messaging. 

 The  future  spectrum  needs  of  the  maritime  mobile  service  in  the  HF  bands  are  closely  related  to  the  introduction  of  new  data  exchange  technologies  into  the  maritime  mobile 
 service,  as  an  alternative  standard  for  narrow-  band  direct  printing  (NBDP).  The  use  of  NDBP  is  in  rapid  decline  for  commercial  communications.  IMO  has  noted  NBDP  is 
 currently  used  for  broadcasting  of  MSI,  ship  reporting,  weather  forecasts  and  for  business 
56
 WAC/  104A(  27.04.06) 
 57 
 communications,  e.  g.,  by  fishing  fleets.  However,  all  these  functions  could  in  principle  be  provided  by  alternative  HF  data  communications  technology.  A  PDNR  for  the  new 
 MMS  HF  data  exchange  service  has  been  developed  based  on  commercial  Orthogonal  Frequency  Division  Modulation  (OFDM)  (see  8B/  135). 

 NBDP  remains  useful  for  providing  distress  communications  in  the  polar  regions  (sea  area  A4)  when  other  terrestrial  means  of  communication  are  no  longer  reliable  because  of 
 atmospheric  noise,  and  there  is  no  coverage  from  geostationary  satellite  networks  providing  service  to  the  maritime  community.  This  NBDP  functionality  will  be  preserved 
 using  the  HF  distress  and  safety  frequencies  relocated  to  Appendix  15. 
 Because  the  studies  on  this  issue  are  continuing,  a  revision  of  Resolution  351  to  recognize  the  current  views  of  the  IMO  regarding  the  technology  transition,  to  note  the 

 transition  that  has  already  taken  place,  and  to  direct  additional  studies  regarding  the  spectrum  needed  for  new  technologies  is  appropriate. 

 Resolution  544: 
 Important  aspects  of  the  recent  history  leading  to  this  Resolution  begin  with  the  preparation  for  Agenda  Item  1.36  for  WRC-  03.  That  agenda  item  called  for  a  study  of  the 
 spectrum  requirements  between  4  MHz  and  10  MHz  as  seen  by  the  broadcasting  service.  After  intensive  study  by  members  of  the  broadcasting  service,  these  requirements  were 
 documented  quantitatively  through  the  activities  of  the  ITU-  Rs  Study  Group  6,  and  subsequently  reported  in  the  CPM-  02  report  for  use  by  the  WRC-  03. 

 The  essence  of  these  study  results  from  the  broadcasting  service  Study  Group  was  that  there  is  a  significant  deficiency  of  spectrum  availability  in  the  current  BS  allocations 
 between  roughly  4  MHz  and  10  MHz  compared  to  the  demand  for  broadcast  transmission  channels.  A  major  conclusion  from  the  analysis  was  that  it  would  take  about  250  kHz  of 
 additional  spectrum  to  eliminate  co-  channel  interference  that  is  currently  unavoidable  and  roughly  850  kHz  total  to  remove  first  adjacent  channel  interference  along  with  the  co-channel 
 interference. 
 In  the  main,  these  results  were  based  upon  a  scrutiny  of  the  databases  used  by  the  frequency  assignment  coordinating  committees,  for  example  the  HFCC,  for  all  the  semi-annual 
 periods  coming  a  few  years  before  CPM-  02.  These  results  were  effectively  independent  of  the  particular  sunspot  cycle  values  during  these  years. 

 These  values  of  a  deficiency  of  spectral  supply  vs.  broadcasting  demand  were  accepted  at  WRC-  03.  However,  it  did  not  act  upon  any  suggestions  for  a  decision  by  it  for  any 
 reallocation  of  the  4  MHz  to  10  MHz  band  range.  Instead,  it  produced  Resolution  544.  This  resolution,  together  with  the  development  of  Agenda  Item  1.13,  strongly  suggests 
 that  WRC-  07  come  to  closure  on  the  main  issue  of  a  reallocation  among  some  of  the  services  in  this  6  MHz  wide  HF  band.

 Between  WRC-  03  and  now,  continued  study  has  been  engaged  in  updating  the  statistical  summaries  on  the  shortfall  in  two  aspects: 
 (1)  The  first  is  to  add  to  the  analysis  the  statistics  from  the  coordinating  committees  for  semi-  annual  seasons  since  2002.  This  has  been  done  and  reported  upon 
 through  the  activities  of  WP6E.  Now,  for  a  5  year  period,  covering  both  relatively  high  and  relatively  low  sunspot  activity  seasons,  the  same  basic  shortfall 
 conclusion  persists.  The  fundamental  broadcasting  demand  has  remained  and  the  below  10  MHz  HF  spectrum  requirement  is  still  needed  at  roughly  the  same  level 
 independent  of  sunspot  activity.  (The  latter  is  clearly  shown  analytically  in  propagation  analysis  comparisons  at  various  sunspot  numbers  and  times  of  the 
 year,  and  is  noted  in  considering  e)  of  this  Resolution.)  In  short,  no  significant  trend  has  appeared  that  would  alter  this  conclusion. 

 (2)  Questions  came  to  WP6E  in  the  form  of  Liaison  Statements  from  other  Working  Parties  about  the  continuity  during  a  scheduling  season  of  the  shortfall  after 
 transmissions  have  begun  and  some  adjustments  have  been  made  based  upon  the  feedback  that  the  broadcasting  community  receives  via  its  HF  monitoring 
 networks.  It  was  pointed  out,  through  WP6Es  replies  to  these  Liaison  Statements,  that  the  statistical  summaries  provided  included  the  situations  after  a  month  or 
 two  of  seasonal  operation,  that  is,  after  all  adjustments  to  avoid  interference  that  could  be  made  were  made.  The  other  Working  Parties  accepted  this  finding. 

 This  Resolution  in  considering  g)  notes  that  the  introduction  of  new  digital  technology  will  not  completely  solve  current  congestion  problems.  Since  the  end  of  WRC-  03,  many 
 HF  broadcasters  have  begun  regular  digital  modulation  broadcasts  using  the  DRM  system,  which  is  the  ITU-  R  recommended  system  and  which  has  been  standardized  by 
 the  ITU,  IEC  and  ETSI.  The  level  of  broadcasting  is  now  hundreds  of  hours  per  day,  which  is  still  only  a  small  fraction  of  the  total  daily  HF  broadcasting.  These  are  not 
 replacement  broadcasts,  but  additional  ones  from  the  usual  analog  AM  ones.  Thus,  so  far,  there  is  no  diminishment  of  broadcasting  transmission  demand  because  of  digital 
 modulation. 
 Serious  attempts  have  been  made  to  predict  the  impact  of  digital  modulation,  in  the  middle-  and  long-  term  on  the  spectral  needs  for  HF  broadcasting.  The  primary  conclusion 
 is  that  there  is  no  current,  reasonable  way  to  state  that  digital  modulation  broadcasting  will  significantly  increase  or  significantly  decrease  the  demand  for  HFBC  channels.  On 
 the  one  hand,  the  introduction  of  this  new  modulation  technique  could  greatly  increase  the  interest  in  international  and  domestic  broadcasting  in  the  HF  bands  because  of  the 
 clear  advantages  it  provides  over  traditional  analog  broadcasting;  on  the  other  hand,  it  could  eventually  reduce  the  need  of  multiple  transmissions  on  different  frequencies  for 
 the  same  target  area  that  many  of  the  major  broadcasters  employ  to  increase  the  probability  of  a  clear  signal  at  the  targeted  reception  area.  Finally,  a  reasonable 
 conclusion  on  this,  given  the  5  years  worth  of  solid  data  since  2000  and  some  indication  that  it  will  take  several  years  even  to  obtain  an  indication  of  the  true  impact  of  digital 
58
 WAC/  104A(  27.04.06) 
 59 
 modulation  on  spectral  demand,  is  that  the  current  demand  vs.  capacity  shortfall  will  be  apparent  for  a  long  time. 
 A  condition  relative  to  this  Resolution  and  HF  broadcast  spectral  demand  at  frequencies  below  10  MHz  is  that  considerable  broadcasting  is  done  in  bands  nearby,  but  not  in,  the 
 Article  5  HFBC  bands.  This  is  a  consequence  of  the  shortfall  in  the  HFBC  bands.  Its  use,  invoking  Article  4.4  (non-  interference),  amounts  to  roughly  15%  of  all  HF 
 broadcasting.  Additional  data  from  one  administration  show  that  approximately  40%  of  the  non-  government  broadcasting  done  under  its  auspices  uses  frequencies  outside  of  the 
 broadcasting  bands  between  4  and  10  MHz  due  to  the  lack  of  available  channels  in  these  bands  that  are  necessary,  based  upon  propagation  analysis,  to  provide  adequate  signal 
 strength  in  the  intended  broadcast  areas.  This  Resolution  and  Agenda  Item  1.13  itself  have  been  approved  to  redress  this  situation  to  the  maximum  level  possible. 

 To  summarize,  this  Resolution  was  approved  at  WRC-  03  with  the  full  understanding  by  the  Conference  that  a  persistent  problem  exists  with  respect  to  a  deficit  of  spectrum 
 required  for  the  broadcasting  service  between  4  MHz  and  10  MHz.  Furthermore,  all  the  quantitative  data  available  from  scheduling  coordination  committees  show  that  this 
 deficit  level  is  severe  (250  to  850  kHz,  depending  on  eliminating  co-  channel  interference  only  or  all  interference),  and  the  best  predictions  available  indicate  that  in  the  large  this 
 will  continue. 

 Resolution  729: 
 resolves 
 1  that,  in  authorizing  the  operation  of  frequency  adaptive  systems  in  the  MF  and  HF  bands,  administrations  shall: 

 1.1  make  assignments  in  the  bands  allocated  to  the  fixed  and  mobile  services; 
 1.2  not  make  assignments  in  the  bands: 
 -  allocated  exclusively  to  the  maritime  or  aeronautical  mobile  (R)  services; 

 -  shared  on  a  co-  primary  basis  with  the  broadcasting  service,  radiodetermination  service  or  the  amateur  services; 
 -  allocated  to  radio  astronomy; 
 1.3  avoid  use  which  may  affect  frequency  assignments  involving  safety  services  made  in  accordance  with  Nos.  5.155,  5.155A  and  5.155B; 

 1.4  take  into  account  any  footnotes  applicable  to  the  proposed  bands  and  the  implications  regarding  compatibility; 
59
 WAC/  104A(  27.04.06) 
 60 
 2  that  frequency  adaptive  systems  shall  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements; 
 3  that,  with  a  view  to  avoiding  harmful  interference,  the  system  should  evaluate  the  channel  occupancy  prior  to  and  during  operation; 
 4  that  frequency  adaptive  systems  shall  be  notified  to  the  Bureau  in  accordance  with  the  provisions  of  Article  11, 
 Resolution  729  (WRC-  97)  deals  with  implementation  of  adaptive  HF  systems  and  was  not  successfully  addressed  at  either  WRC-  2000  or  WRC-  2003.  Adaptive  HF  systems  are 
 systems  that  monitor  the  propagation  environment  on  pre-  established  channels,  and  react  to  use  the  optimal  frequencies  available  for  transmission. 

 Frequency  adaptive  systems  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements.  According  to  6E/  223,  which 
 originated  from  WP-  9C,  this  characteristic  of  adaptive  systems  does  not  necessarily  reduce  the  number  of  frequencies  that  must  be  made  available  to  ensure  successful  link 
 establishment.  Consideration  must  also  be  given  to  maintain  quality  of  service  for  uses  that  fluctuate  in  response  to  situations  such  as  those  that  arise  during  Public  Protection 
 and  Disaster  Relief.  The  number  of  frequencies  in  an  adaptive  frequency  pool  is  directly  interrelated  to  the  specific  HF  propagation  characteristics  based  on  time  of  day,  season, 
 sunspot  activity,  etc.  Therefore,  efficiency  improves  as  more  frequencies  are  available.  A  network  of  stations  is  assigned  a  number  of  frequencies  over  which  to  communicate, 
 and  each  station  is  assigned  a  unique  address  (e.  g.,  alpha-  numeric). 
 Adaptive  HF  systems  have  been  in  use  for  over  20  years.  No  special  consideration  in  the  ITU  Radio  Regulations  is  required  to  fully  implement  adaptive  HF  systems.  By  their 

 nature  these  systems  already  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements.  These  systems  also  automatically 
 avoid  harmful  interference  by  evaluating  the  channel  occupancy  prior  to  and  during  operations. 

 To  fully  exploit  modern  HF  technology,  the  availability  of  sufficient  and  coordinated  spectrum  resources  is  crucial,  and  bandwidth  beyond  the  typical  3  kHz-  channels  must  be 
 available. 
 The  channel  bonding  approach  currently  in  use  is  based  on  the  use  of  several  3  kHz  contiguous  channels.  The  advent  of  HF  64  kbps  modems  has  begun  to  provide  the  ability 

 to  utilize  HF  spectrum  for  Internet,  large  file  transfer,  and  advanced  electronic  messaging.  Loss  of  HF  spectrum  allocated  to  the  fixed  and  mobile  services  would 
 constrain  the  development  of  advanced  technologies  such  as  messaging,  file  transfer,  and  the  Internet. 

 The  required  studies  related  to  adaptive  HF  technology  have  been  adequately  answered.  Therefore,  Resolution  729  can  be  suppressed. 
60
 WAC/  104A(  27.04.06) 
 61 
 However,  there  is  an  emergence  of  high  bandwidth  requirements  in  the  form  of  advanced  fixed  and  mobile  HF  systems  which  does  require  urgent  study.  Therefore  a  new 
 resolution  is  required  to  examine  the  issues  involved  in  implementing  advanced  fixed  and  mobile  HF  systems  in  the  MF/  HF  bands. 

 Sharing  considerations:  A  key  element  to  satisfy  Agenda  Item  1.13  in  its  entirety  is  to  determine  how,  if  at  all 
 possible,  the  allocations  between  4  MHz  and  10  MHz  can  be  revised  to  permit  additional  allocations  to  the  broadcasting  service  without  adversely  affecting,  or  minimally 
 affecting,  the  other  services  within  this  6  MHz  since  this  spectrum  is  of  value  to  all  the  services  that  have  allocations  therein. 

 Considerable  thought  over  the  years  has  been  given  to  the  sharing  possibilities  among  the  services.  Focusing  on  recent  events,  the  CPM-  02  report,  for  the  WRC-  03  Agenda  Items 
 1.23  and  1.36,  summarized  the  situation.  Its  conclusions  on  this  matter  have  not  been  modified  by  the  ITU-  R  Study  Group  activities  since  the  end  of  WRC-  03 

 This  summarization  is  consistent  with  many  ITU-  R  reports  over  the  years.  It  states  that  if  at  all  possible  allocations  for  the  broadcasting  service  (one  way/  high  power)  should  not 
 be  made  on  a  co-  primary  basis  with  any  of  the  other  services  that  wish  to  use  HF.  Secondly,  the  other  services  in  many  situations  can  share  on  a  co-  primary  basis  with  each 
 other.  These  are  general  statements  that  take  no  account  of  the  specific  uses  of  certain  transmissions  within  a  service.  Clearly,  each  use  has  to  be  studied  with  its  own  sharing 
 constraints  in  mind. 
 After  detailed  discussion,  and  recognizing  (a)  the  fact  that  the  broadcasting  community  regularly  transmits  broadcasts  in  certain  of  the  fixed  service  bands,  under  Article  4.4, 
 with  a  minimum  of  harmful  interference  events,  and  (b)  the  regulatory  difficulty  of  transferring  some  of  the  current  fixed  service,  etc.  allocations  to  maritime  mobile  service 
 allocated  frequencies  on  a  shared  basis,  we  believe  the  simplest,  most  practical  solution  for  all  the  services  involved  in  the  4    10  MHz  part  of  the  spectrum  is  to  have  the 
 broadcasting  service  and  the  fixed,  mobile  and  land  mobile  services  share  on  a  non-exclusive  co-  primary  basis. 

 Transition  arrangements  for  any  reallocation  need  to  be  developed  since  it  is  understood  that  any  reallocation  will  require  an  adequate  time  to  take  place.  If  the  overall 
 reallocation  solution  includes  no  movement  for  the  fixed,  mobile  and  land  mobile  services,  a  transition  period  could  be  a  short  one.

 Additional  spectrum  for  the  broadcasting  bands  in  the  HF  bands  between  4  MHz  and  10  MHz 

 For  all  three  Regions  allocate  the  following  frequency  bands  to  the  broadcasting  service  on  a  co-  primary,  that  is,  non-  exclusive,  basis  with  the  fixed,  mobile  and  land  mobile 
 services  (see  the  Table  for  details): 
 5  060  -  5100  kHz  5  840  -  5  900  kHz 
 7  450  -  7  600  kHz  9  340  -  9  400  kHz 
 9  900  -  9  940  kHz, 
 for  a  total  of  350  kHz. 
 All  of  these  parts  are  portions  of  the  bands  listed  as  preferred  bands  in  Res.  544.

 Reasons:  There  is  ample  evidence  that  the  broadcasting  service  has  a  requirement  for  additional 
 spectrum  allocations  in  this  portion  of  the  spectrum.  This  is  substantiated  by  several  years  of  carefully  compiled  statistics  comparing  channel  demand  with  channel  capacity  in  its 
 existing  allocations  between  4  and  10  MHz.  Collisions,  that  is,  unavoidable  mutual  interference,  occur  to  the  extent  of  a  channel  deficit  the  equivalent  of  250  kHz  for  co-channel 
 interference  and  around  800    850  kHz  to  include  the  removal  of  adjacent  channel  interference. 

 In  addition,  in  attempts  to  avoid  this  situation,  some  broadcasters  resort  to  spillover  broadcasting  into  nearby  fixed,  mobile  and  land  mobile  bands,  with  the  broadcasters 
 operating  under  Article  4.4.  Broadcast  channel  occupation  statistics  show  that  this  out-of-  band  broadcasting  covers  roughly  15%  of  all  broadcasts  below  10  MHz.  This  de  facto 
 situation  needs  to  be  remedied  because  many  administrations,  acting  as  host  administrations  for  HFBC  transmission  sites,  do  not  permit  out-  of-  band  broadcasting. 
 This  has  the  effect  of  forcing  some  smaller  broadcasting  organizations  to  rely  upon  out-of-  band  broadcasting  well  beyond  the  15%  average  value  mentioned  above. 

 Remedying  this  situation,  without  operationally  penalizing  the  fixed,  mobile  and  land  mobile  service  users  of  the  spectrum  where  the  broadcast  service  users  now  operate  on  an 
65
 WAC/  104A(  27.04.06) 
 66 
 Article  4.4  basis  can  be  done  in  two  ways:  (a)  have  the  broadcasting  service  share  with  the  non-  broadcasting  services  in  a  fraction  of  the  allocations  for  the  non-  broadcasting 
 services  involved  or  (b)  reallocating  these  non-  broadcasting  services  to  share  within  certain  parts  of  the  maritime  mobile  service  allocations  within  the  4    10  MHz  portion  of 
 the  spectrum.  Because  of  the  wording  of  Agenda  Item  1.13,  and  for  some  operational  reasons,  the  latter  method  is  less  attractive  than  the  former. 

 Therefore,  contiguous  with  existing  broadcasting  service  bands,  5  non-  broadcasting  bands  are  proposed  for  use  on  a  non-  exclusive  basis  for  the  broadcasting  service  and 
 those  with  the  current  allocation  (see  the  Table  above).  (Note:  The  only  exception  to  this  contiguity  is  that  in  Region  2  the  band  7400    7450  kHz  is  allocated  to  the  fixed  and 
 mobile  services  rather  than  the  broadcasting  service.  This  leaves  a  50  kHz  gap  to  the  nearest  broadcasting  service  band,  which  ends  at  7400  kHz.)  These  350  kHz  in  total 
 account  for  14  %  of  the  total  fixed,  mobile  and  land  mobile  services  allocations  in  the  4    10  MHz  portion  of  the  spectrum. 

 The  fixed,  mobile  and  land  mobile  allocations  in  these  bands  will  not  be  eliminated.  The  change  amounts  to  a  sharing  situation  among  these  services  and  the  broadcasting  service. 
 Although  not  the  most  attractive  in  theory  of  the  sharing  possibilities  within  the  4    10  MHz  part  of  the  spectrum,  it  is  noted  that  the  current  out-  of-  band    use  of  these 
 frequencies  by  some  of  the  broadcasting  service  users  under  Article  4.4  has  seldom  caused  harmful  interference  with  the  other  service  uses.  With  the  increased  use  of 
 adaptive  techniques  (see  Res.  729),  it  can  be  expected  that  interference  under  a  co-primary  allocation  will  not  increase,  and  may  decrease. 

 This  proposed  allocation  revision  also  avoids  the  possibility  of  suggesting  that  the  fixed,  mobile  and  land  mobile  services  might  share  the  amount  of  spectrum  given  to  the 
 broadcasting  service  by  moving  into  a  sharing  situation  with  elements  of  the  maritime  mobile  service.  Thus,  a  potentially  difficult  situation  is  avoided.

 Transition  period  arrangements 
 5.  ABC  The  additions  of  a  primary  allocation  to  the  broadcasting  service  in  the  bands  5060    5100  kHz,  5840    5900  kHz,  7450    7600  kHz,  9340    9400  kHz  and  9900   
 9940  kHz  will  be  effective  starting  30  March  2009. 

 Reason:  Since  the  reallocation  proposal  does  not  involve  reallocating  the  fixed,  mobile  and  land 
 mobile  allocations,  a  transition  period  should  not  need  a  long  period  to  take  effect.  Therefore,  it  is  proposed  that  the  additions  for  the  broadcasting  service  take  effect  on  30 
 March  2009.  This  is  to  synchronize  with  the  WRC-  03  decision  on  the  amateur  services

 Footnote  on  emergency  responses 
 5.  DEF  For  those  frequency  allocations  listed  in  footnote  5.  ABC,  administrations  who  control  assignments  for  the  broadcasting  service  to  transmit  to  CIRAF  zones  that  have 
 been  declared  by  competent  authorities  to  be  emergencies  of  a  disaster  or  public  safety  nature  shall  immediately  notify  these  broadcasters  of  the  situation  and  instruct  them  to 
 cease  regular  broadcasting  in  accordance  with  the  Article  12  coordination  procedure  until  further  notice  to  recommence  broadcasting.  This  does  not  preclude  the  broadcasters  to 
 transmit  messages  that  may  be  approved  by  the  authorities  in  the  affected  CIRAF  zones. 
 Reason:  The  ITU-  R,  among  many  other  international  organizations,  is  deeply  concerned  about 
 communication  and  other  techniques  to  be  used  to  respond  rapidly  to  natural  and  man-made  disasters  and  to  certain  public  safety  situations.  As  part  of  the  overall  arsenal  to 
 deal  with  these  problems,  this  proposed  footnote,  as  a  pioneering  measure  perhaps  for  other  Article  5  allocations,  will  place  the  ITU-  R  on  record  to  reduce  the  problems  of 
 interference  with  essential  emergency  communications  during  emergency  situations  at  specific  locations.

 Bandwidth  Requirements  for  Advanced  Fixed  and  Mobile  HF  Technologies  in  the  3    30  MHz  Band 

 The  World  Radiocommunication  Conference  (Geneva,  2007), 
 considering 
 a)  that  there  are  a  limited  number  of  fixed  and  mobile  3  kHz  bandwidth  channels,  and  many  channel  bandwidths  are  below  500  Hz,  in  the  planned  portions  of  the  3-  30 

 MHz  band; 
 b)  that  trials  of  advanced  fixed  and  mobile  HF  frequency  systems  have  demonstrated  their  feasibility  and  their  associated  spectrum  efficiency; 

 c)  that  advanced  fixed  and  mobile  HF  frequency  systems  require  larger  channel  bandwidth  assignments  which  currently  can  only  be  accomplished  through  channel 
 bonding; 
 noting 
 that  some  advanced  fixed  and  mobile  HF  frequency  adaptive  systems  utilize  bandwidths  of  up  to  12  kHz  to  support  HF  electronic  messaging,  HF  Internet,  and  HF  file  transfer;

 Draft  Proposal  for  the  Work  of  the  Conference  of  WRC  2007 
 Executive  Summary. 
 This  document  proposes  that  no  additional  spectrum  be  allocated  to  the  Broadcast  Service.  Consideration  has  been  given  to  the  fact  that: 
 a)  the  Broadcast  Service  is  already  scheduled  to  receive  additional  spectrum  in  2007and  again  in  2009  and, 
 b)  some  broadcasters  are  cutting  back  or  eliminating  their  HF  broadcast  services,  but  there  is  an  increasing  demand  for  safety  related  mobile  services. 

 The  serious  consequences  associated  with  allocating  further  additional  spectrum  to  the  Broadcast  Service  at  the  expense  of  Fixed  and  Mobile  is  outlined  in  this  document. 
 Agenda  Item  1.13:  taking  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  MHz  and  10 
 MHz,  excluding  those  allocations  to  services  in  the  frequency  range  7  000-  7  200  kHz  and  those  bands  whose  allotment  plans  are  in  Appendices  25,  26  and  27  and  whose  channelling 
 arrangements  are  in  Appendix  17,  taking  account  of  the  impact  of  new  modulation  techniques  and  the  spectrum  requirements  for  HF  broadcasting; 

 Background:  This  is  a  very  broad  agenda  item,  as  there  are  multiple  services  allocated  to  the  HF  bands  between  4  MHz  and  10  MHz,  including  aeronautical  mobile  (OR),  aeronautical  mobile 
 (R),  amateur,  broadcasting,  fixed,  maritime  mobile  and  mobile  services.  Agenda  item  1.13  covers  three  resolutions  that  deal  with  three  separate  issues.  These  issues  are  connected  within 
 the  agenda  item  on  the  basis  that  they  cover  overlapping  frequency  ranges.  The  Conference  Preparatory  Meet  (CPM)  convened  following  WRC-  03  assigned  the  primary  responsibilities  for 
 the  separate  issues  to  different  ITU-  R  Working  Parties. 
 Resolution  351: 

 resolves 
 1)  that,  in  order  to  provide  full  worldwide  interoperability  of  equipment  on  ships,  there  should  be  one  technology,  or  more  than  one  interoperable  worldwide  technology, 

 implemented  under  Appendix  17; 
 2)  that,  as  soon  as  the  ITU-  R  studies  are  completed,  a  future  competent  conference  should  consider  necessary  changes  to  Appendix  17  to  enable  the  use  of  new  technology  by 

 the  MMS; 
 The  focus  of  Resolution  351  (WRC-  03)  is  to  identify  a  digital  technology,  or  family  of  digital  technologies,  that  provide  interoperability  and  improved  usage  of  the  MF  and  HF  bands  allocated 

 to  the  maritime  mobile  service  under  Appendix  17.  The  scope  of  this  portion  of  the  agenda  item  includes  a  review  of  all  Appendix  17  assignments  to  facilitate  the  introduction  of  these  advanced 
 maritime  mobile  digital  systems. 
69
 70 
 Resolution  351  (WRC-  03)  calls  for  studies  to  include;  future  requirements  of  the  MMS,  technical  characteristics  of  the  digital  systems,  the  necessary  modifications  to  Appendix  17  to 
 enable  the  use  of  new  technologies  by  MMS,  a  timetable  for  the  introduction  of  new  digital  technologies,  and  recommendations  on  how  digital  technologies  can  be  introduced  while 
 ensuring  compliance  with  distress  and  safety  requirements.  In  accordance  with  resolves  2  of  Resolution  351,  as  soon  as  the  ITU-  R  studies  are  completed,  a  competent  conference  should 
 consider  necessary  changes  to  Appendix  17,  to  enable  the  use  of  new  digital  maritime  technologies  by  the  MMS.  These  studies  are  still  underway  and  should  be  refined  to  examine  the 
 requirements  of  GMDSS  electronic  messaging.  The  future  spectrum  needs  of  the  maritime  mobile  service  in  the  HF  bands  are  closely  related  to  the  introduction  of  new  data  exchange 
 technologies  into  the  maritime  mobile  service,  as  an  alternative  standard  for  narrow-  band  direct  printing  (NBDP).  The  use  of  NDBP  is  in  rapid  decline  for  commercial  communications.  IMO 
 has  noted  NBDP  is  currently  used  for  broadcasting  of  MSI,  ship  reporting,  and  weather  forecasts  and  for  safety  related  business  communications.  However,  all  these  functions  could  in  principle 
 be  provided  by  alternative  HF  data  communications  technology.  A  PDNR  for  the  new  MMS  HF  data  exchange  service  has  been  developed  based  on  commercial  Orthogonal  Frequency  Division 
 Modulation  (OFDM)  (see  8B/  135  and  8B/  209). 
 NBDP  remains  useful  for  providing  distress  communications  in  the  Polar  regions  (sea  area  A4)  when  other  terrestrial  means  of  communication  are  no  longer  reliable  because  of  atmospheric 

 noise,  and  there  is  no  coverage  from  geostationary  satellite  networks  providing  service  to  the  maritime  community.  This  NBDP  functionality  will  be  preserved  using  the  HF  distress  and 
 safety  frequencies  listed  in  Appendix  15. 
 Because  the  studies  on  this  issue  are  continuing,  a  revision  of  Resolution  351  to  recognize  the  current  views  of  the  IMO  regarding  the  technology  transition,  to  note  the  transition  that  has 

 already  taken  place,  and  to  direct  additional  studies  regarding  the  spectrum  needed  for  new  technologies  is  appropriate. 

 Resolution  544: 
 resolves  to  invite  ITU-  R 
 1  to  carry  out  studies  on  this  matter,  particularly  in  respect  of  the  bands  identified  in  noting  above,  taking  into  account  technical,  operational,  economic  and  other  relevant 

 factors,  including  the  appropriate  transitional  arrangements,  and  how  the  introduction  of  digital  emissions  will  affect  the  HF  broadcasting  requirements  and  how  such  reallocations 
 will  affect  other  services  using  these  bands. 
 further  resolves 
 "to  recommend  a  future  competent  conference  to  conclude,  where  appropriate,  on  additional  spectrum  requirements  for  the  broadcasting  service,  taking  into  account  the  interest  of  all 

 affected  services" 
 Resolution  544  (WRC-  03)  resulted  from  work  that  was  not  completed  at  WRC-  03.  WRC-  03  allocated  50  kHz  in  Region  2  to  the  broadcast  service  as  a  result  of  the  realignment  of  portions  of 

 the  7  MHz  band  under  WRC-  03  agenda  item  1.23.  Prior  to  WRC-  03,  the  broadcasting  service  identified  a  shortfall  in  the  4-  10  MHz  band  of  250  kHz  of  spectrum  to  alleviate  co-  channel 
70
 71 
 interference,  and  800  kHz  of  spectrum  to  alleviate  adjacent  channel  interference.  The  Resolution  also  called  for  a  review  of  the  impact  of  relocating  other  services  from  current  spectrum 
 allocations  if  these  broadcasting  spectrum  requirements  were  accommodated,  as  well  as  what  transitional  arrangements  should  be  made. 

 WARC-  92  (5.136)  decided  to  allocate  100  kHz  of  spectrum  to  the  broadcasting  service  which  will  transition  from  fixed  and  mobile  service  allocations  in  2007.  Any  further  decrease  in 
 available  spectrum  may  affect  the  ability  of  fixed  and  mobile  service  users  to  establish  and  maintain  reliable,  essential  and  emergency  communications  services.  Any  consideration  by 
 WRC-  07  to  reallocate  additional  spectrum  to  the  broadcast  service  should  carefully  consider  the  impact  on  existing  and  planned  fixed  and  mobile  services.  Currently,  there  are  2  102  kHz 
 between  4  and  10  MHz  allocated  to  support  the  land  mobile  services  and  2  712  kHz  allocated  to  the  fixed  service.  After  April  1,  2007,  implementation  of  the  results  of  WARC-  92  reduces  that 
 amount  to  2  002  kHz  for  land  mobile  and  2  512  kHz  for  the  fixed  service  as  a  result  of  the  reallocation  to  the  broadcast  service.  After  March  29,  2009,  in  Region  2  an  additional  50  kHz  is 
 allocated  from  the  fixed  and  land  mobile  services  to  the  broadcast  service. 
 Because  of  their  reliability  and  low  cost,  fixed  and  mobile  HF  services  will  continue  to  be  required  by  Administrations.  Administrations  must  be  ready  to  support  fluctuations  in  demand 

 by  the  fixed  and  mobile  service  during  emergency  communications.  The  fixed  and  mobile  services  are  unique  in  that  requirements  to  use  them  increase  during  emergency  and  disaster 
 situations.  Public  Protection  and  Disaster  Relief  operations  depend  on  the  availability  of  spectrum  to  support  operations. 

 Displacement  of  current  frequencies  from  the  fixed  and  mobile  service  may  require  considerable  expenses  for  realignment  of  communication  networks  and  change  (replacement)  of  antennas.  In 
 some  cases  it  may  be  difficult  to  establish  required  radio  links  based  on  the  loss  of  currently  available  portions  of  the  spectrum,  and  due  to  spectrum  crowding  from  realignment  of 
 assignments  to  account  for  any  spectrum  allocated  from  the  fixed  and  mobile  service  to  the  broadcast  service. 

 The  operational  database(  s)  maintained  by  the  HF  Coordinating  Committee  (HFCC)  illustrate  that  a  broadcast  primary  allocation  of  250  kHz  of  spectrum  would  alleviate  co-  channel 
 interference,  and  800  kHz  of  spectrum  would  alleviate  adjacent  channel  interference.  According  to  text  contained  in  WP-  8A/  199,  which  originated  from  WP-  6E,  the  HF  broadcasters  currently 
 address  this  shortfall  by  using  FS  and  LMS  bands  on  a  non-  interference  basis  under  Article  4.4.  According  to  WP  6E/  162,  80-  85%  of  shortwave  broadcasting  hours  in  the  4-  10  MHz  band 
 operates  within  broadcasting  allocations  and  do  not  operate  under  Article  4.4. 
 There  is  interference  risks  associated  with  Article  4.4  operation.  The  HFCC  and  Administrations  need  to  take  these  risks  into  account  when  assessing  cross  border  interference  potential  and 

 coordinating  usage  under  Article  4.4.  Some  Administrations  have  reported  interference  from  the  broadcast  service  in  the  fixed  and  mobile  bands.  At  least  one  incident  resulted  in  discontinuation 
 of  broadcaster  operations.  Given  this  interference  risk,  Article  4.4  operations  do  not  represent  successful  broadcaster  occupancy  of  the  fixed  and  mobile  bands,  nor  do  they  justify  reallocation 
 of  these  portions  of  the  fixed  and  mobile  bands  to  the  broadcasting  service.

 HF  Broadcast  providers  are  currently  investing  in  alternate  delivery  methods,  which  may  be  used  to  augment  or  replace  programming  hours.  FM,  cable,  satellite,  and  Internet  are  beginning  to 
 provide  alternate  delivery  in  developed  countries,  but  are  problematic  for  developing  countries  due  to  cost,  coverage,  and  reliability. 

 Recent  public  announcements  by  some  broadcasters  confirm  that  there  is  a  decline  in  the  need  for  HF  broadcast  spectrum. 
 Recent  natural  disasters  have  demonstrated  that  the  fixed  and  mobile  services  are  unique  in  comparison  to  the  broadcast  service  in  that  requirements  are  driven  up  rapidly  during  the 
 development  of  emergency  situations.  Increased  congestion  is  inevitable  during  periods  of  peak  usage  by  the  fixed  and  mobile  services. 

 ITU-  R  WP  9C  has  noted  that  during  the  2004-  2005  Indian  Ocean  Tsunami  Relief  Effort,  the  emergent  need  for  HF  communications  drove  up  spectrum  demand  rapidly.  Because  of  existing 
 extensive  usage  of  the  HF  bands  in  disaster  areas,  it  was  not  possible  to  provide  all  the  required  channels  to  meet  required  emergency  communications.  Ionospheric  (skywave)  signal 
 propagation  is  frequency  selective  and  frequencies  usable  for  communications  between  any  two  points  change  over  time  throughout  the  day.  This  is  why  several  different  segments  of  spectrum 
 within  the  HF  frequency  range  are  allocated  to  each  radio  service.  This  enables  the  users  of  the  service  to  have  full  time  access  to  frequencies  that  are  usable  throughout  a  24-  hour  period. 

 For  the  fixed  and  mobile  services,  propagation  concerns  make  it  essential  that  the  frequency  channels  or  sub-  bands  of  an  HF  pool  are  evenly  spaced  in  order  to  adapt  to  the  daily  and  seasonal 
 changes  in  the  ionosphere.  That  is  why  spectrum  is  allocated  to  the  different  services  throughout  the  4  to  30  MHz  range. 

 The  impact  to  the  fixed  and  mobile  services  of  allocating  additional  spectrum  to  the  broadcasters  would  be  too  severe,  since  those  additional  allocations  would  come  from  bands  assigned  to  these 
 services.  This  situation  will  not  change  in  the  foreseeable  future. 
 The  examples  below  show  the  specific  services  that  would  be  negatively  affected  by  the  proposed  re-  allocation  of  spectrum. 

 On-  air  monitoring  up  to  19  September  2005  shows  that  the  following  services  would  be  affected:

 Further  support  for  this  proposal  will  be  found  in  Annex  1 

 Resolution  729: 
 resolves 
 1  that,  in  authorizing  the  operation  of  frequency  adaptive  systems  in  the  MF  and  HF  bands,  administrations  shall: 

 1.1  make  assignments  in  the  bands  allocated  to  the  fixed  and  mobile  services; 
 1.2  not  make  assignments  in  the  bands: 
 -  allocated  exclusively  to  the  maritime  or  aeronautical  mobile  (R)  services; 
 -  shared  on  a  co-  primary  basis  with  the  broadcasting  service,  radio  determination  service  or  the  amateur  services; 

 -  allocated  to  radio  astronomy; 
 1.3  avoid  use  which  may  affect  frequency  assignments  involving  safety  services  made  in  accordance  with  Nos.  5.155,  5.155A  and  5.155B; 

 1.4  take  into  account  any  footnotes  applicable  to  the  proposed  bands  and  the  implications  regarding  compatibility; 
 2  that  frequency  adaptive  systems  shall  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements; 
75
 76 
 3  that,  with  a  view  to  avoiding  harmful  interference,  the  system  should  evaluate  the  channel  occupancy  prior  to  and  during  operation; 
 4  that  frequency  adaptive  systems  shall  be  notified  to  the  Bureau  in  accordance  with  the  provisions  of  Article  11, 
 Resolution  729  (WRC-  97)  deals  with  implementation  of  adaptive  HF  systems  and  was  not  successfully  addressed  at  either  WRC-  2000  or  WRC-  2003.  Adaptive  HF  systems  are  systems 
 that  monitor  the  propagation  environment  on  pre-  established  channels  and  react  to  use  the  optimal  frequencies  available  for  transmission. 

 Frequency  adaptive  systems  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements.  According  to  ITU-  R  WP  6E/  223,  which  originated 
 in  ITU-  R  WP  9C,  this  characteristic  of  adaptive  systems  does  not  necessarily  reduce  the  number  of  frequencies  that  must  be  made  available  to  ensure  successful  link  establishment. 
 Consideration  must  also  be  given  to  maintain  quality  of  service  for  uses  that  fluctuate  in  response  to  situations  such  as  those  that  arise  during  Public  Protection  and  Disaster  Relief.  The  number  of 
 frequencies  in  an  adaptive  frequency  pool  is  directly  interrelated  to  the  specific  HF  propagation  characteristics  based  on  time  of  day,  season,  sunspot  activity,  etc.  Therefore,  efficiency 
 improves  as  more  frequencies  are  available.  A  network  of  stations  is  assigned  a  number  of  frequencies  over  which  to  communicate,  and  each  station  is  assigned  a  unique  address. 

 Adaptive  HF  systems  have  been  in  use  for  over  20  years.  No  special  consideration  in  the  ITU  Radio  Regulations  is  required  to  fully  implement  adaptive  HF  systems.  By  their  nature  these 
 systems  already  automatically  limit  simultaneous  use  of  frequencies  to  the  minimum  necessary  for  communication  requirements.  These  systems  also  automatically  avoid  harmful  interference 
 by  evaluating  the  channel  occupancy  prior  to  and  during  operations. 
 To  fully  exploit  modern  HF  technology,  the  availability  of  sufficient  and  coordinated  spectrum  resources  is  crucial,  and  bandwidth  beyond  the  typical  3  kHz-  channels  must  be  available.  The 

 ITU-  R  WP  8B  proposal  (WP  8B/  135)  takes  this  into  account  for  the  MMS. 
 The  channel  bonding  approach  currently  in  use  is  based  on  the  use  of  several  3  kHz  contiguous  channels.  The  advent  of  HF  64  kbps  modems  has  begun  to  provide  the  ability  to  utilize  HF  spectrum  for  Internet, 
 large  file  transfer,  and  advanced  electronic  messaging.  Loss  of  HF  spectrum  allocated  to  the  fixed  and  mobile  services  would  constrain  the  development  of  advanced  technologies  such  as  messaging,  file 
 transfer,  and  the  Internet. 
 The  required  studies  related  to  adaptive  HF  technology  have  been  adequately  answered.  Therefore,  Resolution  729  can  be  suppressed. 

 However,  there  is  an  emergence  of  high  bandwidth  requirements  in  the  form  of  advanced  fixed  and  mobile  HF  systems,  which  does  require  urgent  study.  Therefore  a  new  resolution  is  required  to  examine 
 the  issues  involved  in  implementing  advanced  fixed  and  mobile  HF  systems  in  the  MF/  HF  bands.

 The  World  Radio  communication  Conference  (Geneva,  2007), 
 Reasons:  Editorial 
 considering 

 a)  that  the  agenda  of  this  Conference  included  consideration  of  the  use  of  new  digital  technology  in  the  maritime  mobile  service  (MMS)  in  the  MF  and  HF  bands; 

 b)  that  the  introduction  of  new  digital  technology  in  the  MMS  shall  not  disrupt  the  distress  and  safety  communications  in  the  MF  and  HF  bands  including  those  established  by  the 
 International  Convention  for  the  Safety  of  Life  at  Sea  (SOLAS),  1974,  as  amended; 
 c)  that  changes  made  in  Appendix  17  should  not  prejudice  the  future  use  of  these  frequencies  or  the  capabilities  of  systems  or  new  applications  required  for  use  by  the  MMS; 

 d)  that  the  need  to  use  new  digital  technologies  in  the  MMS  is  growing  rapidly; 
 e)  that  the  use  of  new  digital  technology  on  HF  and  MF  frequencies  allocated  to  the  MMS  will  make  it  possible  to  better  respond  to  the  emerging  demand  for  new  services; 

 f)  that  the  HF  bands  allocated  to  the  MMS  for  A1A  Morse  telegraphy  are  not  used  for  this  purpose  and  narrow-  band  direct-  printing  (NBDP)  allocations  are  used  by  only  a  small  number  of 
 low  volume  residual  services  at  present;

 h)  that  the  IMO  supports  the  frequencies  of  Appendix  15,  concerning  NBDP,  be  retained  for  the  foreseeable  future. 
 i)  that  the  ITU  Radio  communication  Sector  is  conducting  ongoing  studies  to  improve  the  efficient  use  of  these  bands, 
 noting 
 a)  that  different  digital  technologies  have  already  been  developed  and  are  in  use  in  the  MF  and  HF  bands  in  several  radio  communication  services, 

 b)  that  new  maritime  HF  data  transfer  protocols  have  already  been  developed  to  replace  general  narrow-  band-  direct-  printing  communications  using  Appendix  17  frequencies  and  mobile 
 frequencies  outside  Appendix  17 
 noting  also 
 that  this  conference  has  modified  Appendix  17  to  permit  the  use  of  various  channels  or  bands  identified  in  the  MF  and  HF  bands  for  the  introduction  of  new  digital  technology,

 2  that,  as  soon  as  the  ITU-  R  studies  are  completed,  a  future  competent  conference  should  consider  necessary  changes  to  Appendix  17  to  facilitate  the  use  of  new  technology  by  the  MMS, 
 invites  ITU-  R 
 to  finalize  studies  currently  ongoing: 
   to  identify  future  requirements  of  the  MMS; 
   to  identify  the  technical  characteristics  necessary  to  facilitate  use  of  digital  systems  in  the  MF  and  HF  bands  allocated  to  the  Mobile  Service,  taking  into  account  any 

 relevant  ITU-  R  Recommendations;

 instructs  the  Secretary-  General 
 to  bring  this  Resolution  to  the  attention  of  the  International  Maritime  Organization,  the  International  Civil  Aviation  Organization,  the  International  Association  of  Marine  Aids  to 

 Navigation  and  Lighthouse  Authorities  and  the  Comit  International  Radio-  Maritime. 
 Reasons:  There  are  still  several  studies  underway  that  need  to  be  completed  prior  to  resolving  this  issue.  These  studies  should  be  completed  prior  to  the  next  Conference  after  WRC-  07,  where 

 the  appropriate  changes  to  the  RR  can  be  considered. 

 USA/  /3  SUP 
 RESOLUTION  544  (WRC-  03) 
 Identification  of  additional  spectrum  for  the  broadcasting  service  in  the  HF  bands 

 Reasons:  The  impact  to  the  fixed  and  mobile  community  is  too  severe  to  allocate  additional  spectrum  to  the  broadcast  service  that  would,  in  fact,  come  from  bands  assigned  to  these 
 services.  In  addition,  the  long  term  need  for  additional  broadcasting  spectrum  is  unknown.  Additional  spectrum  reallocated  to  the  broadcast  service  would  result  in  congestion  to  the  fixed 
 and  mobile  services,  including  the  MMS.  Congestion  is  now  present  in  some  fixed  and  mobile  services  bands.  Recent  operations  supporting  disaster  relief  demonstrated  that  fixed  and  mobile 
 service  requirements  exceeded  the  spectrum  allocated  to  these  services.  Frequencies  used  by  the  MMS  support  general  and  safety  related  communications  as  well  as  Ship  Security  Alert  Systems 
 communications  and  Long  Range  Tracking  and  Identification.  Any  degradation  of  these  services  would  have  severe  consequences.

 Bandwidth  Requirements  for  Advanced  Fixed  and  Mobile  HF  Technologies  in  the  3    30  MHz  Band 

 The  World  Radio  communication  Conference  (Geneva,  2007), 
 considering 
 a)  that  there  are  a  limited  number  of  fixed  and  mobile  3  kHz  bandwidth  channels,  and  many  channel  bandwidths  are  below  500  Hz,  in  the  planned  portions  of  the  3-  30  MHz  band; 

 b)  that  trials  of  advanced  fixed  and  mobile  HF  frequency  systems  have  demonstrated  their  feasibility  and  their  associated  spectrum  efficiency; 
 c)  that  advanced  fixed  and  mobile  HF  frequency  systems  require  larger  channel  bandwidth  assignments  greater  than  the  3  KHz  assignments  that  are  currently  common. 

 noting 
 that  some  advanced  fixed  and  mobile  HF  frequency  adaptive  systems  utilize  bandwidths  of  up  to  12  kHz  to  support  HF  electronic  messaging,  HF  Internet,  and  HF  file  transfer; 

 resolves  to  invite  ITU-  R 
 1  to  determine  the  feasibility  of  changing  the  Radio  Regulations  to  provide  for  the  use  of  wider  bandwidths  to  support  advanced  fixed  and  mobile  HF  systems  in  the  3    30  MHz  band; 

 2  to  bring  the  results  of  these  studies  to  the  attention  of  WRC-  10 
 Reasons:  Urgent  studies  are  required  to  determine  the  suitability  of  changing  the  radio  regulations  to  allow  for  wider  bandwidths  to  the  fixed  and  mobile  services  to  accommodate  advanced  HF  adaptive 
 systems.

 ANNEX  1 
 IWG-  4  Agenda  Item  1.13 

 The  case  for  no  additional  spectrum  for  any  service 
 IWG-  4  has  received  inputs  from  NASB,  from  the  HF  Users  Group,  and  a  modified  proposal  by  Don  Messer.  Subsequently,  there  was  an  additional  modified  submission  from  the  HF  Users  Group  and 
 numerous  individual  submissions  calling  for  no  additional  broadcast  spectrum.  The  overwhelming  majority  of  opinion  was  in  favour  of  no  additional  spectrum. 

 There  have  been  numerous  discussions  about  the  detailed  wording  of  the  submitted  papers.  However,  such  discussions  are  essentially  irrelevant  until  the  very  simple,  very  straightforward  question  and  entire 
 focus  of  this  discussion  is  settled:  yes  or  no  to  additional  HF  broadcast  spectrum.  With  this  focused  idea,  following  are  some  relevant  considerations. 

 1.  The  decision  has  already  been  made  to  give  the  broadcast  service  additional  spectrum  in  2007  (100  KHz)  and  again  in  2009  (50  KHz). 
 2.  The  broadcast  justification  for  further  additional  spectrum  does  not  take  into  account  the  potential  for  spectrum  saving  through  the  efficient  use  of  digital  broadcasting.  The  broadcast  need  for 
 spectrum  is  likely  to  decline  or,  at  best,  is  uncertain.  This  is  based  on  the  advent  of  new  technologies  such  as  internet  and  satellite  radio.  This  is  made  clear  in  recent  public 
 announcements  from  major  broadcasters.  3.  The  demand  for  mobile  services  and  supporting  spectrum  is  growing  and  forecast  to  continue 
 growing.  There  is  ample  documentation  and  evidence  of  this  in  the  submissions  from  the  various  emergency  services  operators.. 
 4.  Mobile  services  already  suffer  from  broadcast  interference.  New  broadcaster  allocations  would  increase  congestion.  Broadcast  services  are  already  operating  in  the  Maritime  Mobile  Appendix 
 17  spectrum  that  is  shared  with  the  fixed  service.  5.  Broadcast  services  are  already  transmitting  on  the  Appendix  17  maritime  mobile  exclusive 
 frequencies  between  6200  and  6280  KHz  and  causing  interference  to  MMS  communications.  6.  If  additional  spectrum  is  transferred  from  Fixed  &  Mobile  to  Broadcasting,  there  will  be  a  serious 
 deterioration  in  essential  and  critical  safety  services,  including  maritime  security  alerting,  long  range  tracking  and  identification  and  emergency  response  services. 
 7.  If  no  additional  spectrum  is  transferred  to  broadcasting,  there  will  be  no  serious  impact  on  essential,  critical  or  safety  related  services. 
 8.  Co-  primary  status  between  broadcasters  and  fixed  and  mobile  is  unworkable  due  to  time  needed  to  arrange  for  broadcasters  to  vacate  the  spectrum  when  other  means  of  communication  are 
 unavailable  to  first  responders  or  safety  of  life  applications.

 Alternative  dissemination  technologies  such  as  the

 demand  to  the  extent  that  some  HF  broadcasters  have 
 shut  down. 

 New  technologies  offering  improved  efficiencies  and 
 automation  have  increased  demand.  Concerns  about 
 security  and  single  points  of  failure  in  satellite  systems 
 have  also  increased  the  attractiveness  of  and  demand 
 for  HF  systems.  XII.

 XVI.  SPECTRUM 
 XVII.  DEMAND 

 New,  more  spectrum  efficient  technologies  such  as  digital 
 broadcasting  and  SSB  coupled  with  reduced  service  demand 
 point  towards  future  reduced  spectrum  needs.  Intelligent, 
 propagation  based  single  frequency  selection  instead  of 
 multiple  frequency  broadcasts  also  reduces  spectrum  needs. 

 The  new  technologies  require  increased  bandwidth  for 
 increased  throughput.  This  coupled  with  increased  service 
 demand  and  new  service  providers  entering  the  market 
 is  having  a  dramatic  upward  impact  of  spectrum  demand. 
 The  attacks  of  Sept  11  changed  how  HF  is  used  and 
 dramatically  increased  the  demand.

 XX.  CONCLUSION 
 Considering  that: 
 1)  There  is  overwhelming  opposition  to  allocating  additional  Fixed  &  Mobile  spectrum  to  Broadcasting. 
 2)  It  is  in  the  IWG  charter  to  provide  to  the  FCC  proposals  for  WRC  07 
 It  is  proposed  that: 
 IWG-  4  report  to  the  WAC  that  there  is  widespread  support,  with  the  dissenting  view  of  the  broadcasters,  for  no  new  spectrum  allocations  and  the  suppression  of  544.

 Regulatory  Issues 

 DOCUMENT  WAC/  106(  27.04.06): 
 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Agenda  Item  1.10:  to  review  the  regulatory  procedures  and  associated  technical  criteria  of  Appendix  30B  without  any  action  on  the  allotments,  the  existing  systems  or  the  assignments 

 in  the  List  of  Appendix  30B. 
 Background  Information:  As  stated  in    1.1  of  Appendix  30B  the  objective  of  the  Plan  is  to  guarantee  in  practice,  for  all  countries, 
 equitable  access  to  the  geostationary-  satellite  orbit  in  the  frequency  bands  of  the  fixed-  satellite  service  (FSS)  covered  by  this  Appendix.  While  the  plan  has  been  in  force  for  some  18  years,  little  use  has  been 
 made  of  the  precious  spectrum  (1600  MHz)  regulated  by  this  appendix,  particularly  as  compared  to  the  other  bands  allocated  globally  to  the  FSS.  Moreover,  numerous  administrations  have  complained  that  the 
 technical  parameters  and  procedures  are  outdated,  difficult  to  apply,  and  exceedingly  time-  consuming.  For  these  reasons,  administrations  agreed  to  include  consideration  of  this  matter  on  the  agenda  for  WRC-07. 
 Several  ITU-  R  preparatory  meetings  (including  WP-  4A  and  the  Special  Committee)  as  well  as  regional  bodies  have  been  studying  the  related  issues  for  several  years. 
 Taking  the  foregoing  into  consideration,  the  United  States  considers  that  the  conditions  for  the  use  the  Appendix  30B  frequencies  can  be  improved  and  optimized  for  ITU  Member  States  that  want  to 
 implement  their  allotments  as  well  as  for  Administrations  that  want  to  use  capacity  (orbit/  spectrum  resources)  beyond  that  in  the  Plan.  While  some  studies  are  continuing,  and  we  expect  to  continue  to 
 participate  in  the  collaborative  activities  in  the  regional  bodies,  we  offer  a  number  of  proposals  below  to  facilitate  fulfilment  of  the  aspirations  of  all  administrations.  We  may  expect  to  augment  these  proposals 
 when  further  information  becomes  available  in  the  preparatory  activities  leading  to  the  WRC.  Some  key  points  of  these  proposals  are  discussed  in  greater  detail,  below. 
 Processing  of  Submissions  One  of  the  great  concerns  expressed  by  administrations  is  the  lengthy  process  involved  in  the  conversion 
 of  allotments  into  assignments.  While  the  current  sequential  processing  of  submissions  does  allow  for  an  accurate  consideration  of  the  effect  of  each  submission,  the  time  taken  for  this  process  is  prohibitively 
 long.  It  has  been  estimated  that  under  the  current  sequential  approach  the  BR  is  able  to  process  about  8  Appendix  30B  submissions  (with  the  possibility  of  simultaneous  submissions  from  the  same 
 administration  this  number  can  be  slightly  increased).  On  the  other  hand,  on  24  April  2006  there  were  98  of  those  submissions  in  the  BR  queue.  This  corresponds  to  a  backlog  of  at  least  5  years  which  is  very 
 large,  especially  when  compared  to  the  8-  year  limit  for  bringing  Appendix  30B  frequency  assignments  into  use.  Preparatory  discussions  have  highlighted  the  merits  and  disadvantages  resulting  of  the  two 
 approaches:  1)  Continuation  of  Sequential  Processing  and  2)  Non-  Sequential  Processing  of  assignment  applications. 
 With  sequential  processing,  the  reference  situation  is  updated  only  after  the  new  submission  enters  the  List  and  no  other  submission  will  be  examined  until  the  fate  of  each  one  of  the  previous  submissions  has 
 been  decided,  either  by  including  the  associated  network  in  the  List  or  by  removing  it  from  the  queue.  As  a  result,  no  submission  will  be  examined  based  on  a  certain  reference  situation  and  later  enter  the  List 
 when  this  reference  situation  has  changed. 
85
 86 
 A  non-  sequential  processing  of  submissions  4  offers  the  possibility  of  a  greatly  simplified  and  expedited  conversion  of  allotments  into  assignments  (with  or  without  modifications)  and  will  also  reduce  the  time 
 for  processing  other  submissions.  It  does  not  prevent  the  occurrence  of  a  situation  in  which  a  submission  is  examined  under  a  certain  reference  situation  and  enters  the  List  after  satisfying  the  requirements 
 resulting  from  this  examination  when  the  reference  situation  has  already  changed.  In  our  view  the  marginal  inaccuracy  that  may  result  from  this  kind  of  processing  will  be  far  outweighed  by  the  benefits  of 
 a  non-  sequential  processing.  It  is  also  important  to  note  that  non-  sequential  processing  means  that  a  proposed  assignment  B  may  enter 
 the  List  before  an  assignment  A  received  by  the  BR  at  an  earlier  date.  However,  if  the  later  assignment  B  affects  A  (i.  e.  does  not  meet  the  Appendix  30B  protection  criteria),  definitive  registration  of  B  cannot 
 occur  until  A  gives  its  agreement  or  B  changes  its  parameters  so  that  protection  of  A  is  ensured  in  accordance  with  the  Appendix  30B  criteria. 
 If  we  consider  a  submission  under  Article  6  that  is  not  the  conversion  of  an  allotment  into  an  assignment  without  any  change  to  the  characteristics  of  the  allotment,  it  becomes  clear  that  a  non-  sequential 
 processing  is  more  flexible  and  can  potentially  lead  to  a  more  efficient  use  of  orbit/  spectrum  resources.  Under  sequential  processing  an  Article  6  submission  (different  from  conversion  of  an  allotment  without 
 any  change)  that  enters  the  List  and  expires  after  the  8-  year  regulatory  period  without  being  brought  into  use  can  prevent  many  other  submissions  from  staying  in  the  queue.  Under  non-  sequential  processing, 
 Article  6  submissions  could  stay  in  the  queue  and  eventually  enter  the  List  through  a  coordination  agreement  or  after  the  expiration  of  the  assignments  that  were  blocking  their  access.  As  a  consequence  of 
 proposing  a  non-  sequential  processing  of  submissions  the  concept  of  pre-  determined  arc  (PDA)  currently  included  in  the  Appendix  30B  procedures  has  to  be  eliminated  since  it  only  fits  in  a  sequential  processing 
 approach.  It  may  be  argued  that  elimination  of  the  PDA  concept  removes  some  flexibility  in  the  sense  that  an  Article  6  submission  cannot  change  orbital  locations  associated  with  allotments  or  assignments  in 
 the  queue.  However,  this  feature  has  also  some  severe  drawbacks,  such  as  undesirable  and/  or  unexpected  changes  of  orbital  locations  which  also  generate  uncertainty  for  those  administrations  that  have  proposed 
 assignments  in  the  queue  or  are  planning  to  propose  the  conversion  of  an  allotment.  This  uncertainty  is  even  more  damaging  because  of  the  large  backlog  of  submissions  discussed  above.  Such  large  backlog 
 gives  administrations  very  little  time  to  adapt  to  an  ever  changing  environment.  For  the  reasons  discussed  above,  a  new  text  for  Article  6  similar  to  that  appearing  in  Annex  2  of  the 
 output  of  the  WP-  SC  December  2005  meeting  is  proposed  here.  Existing  Systems 

 Existing  systems  are  associated  with  FSS  satellite  networks  that  had  already  been  submitted  to  the  ITU  BR  when  the  Plan  was  developed.  By  now,  the  frequency  assignments  in  these  networks  have  either  been 
 brought  into  use  and  become  assignments  in  the  List  or  have  been  cancelled.  Therefore  there  seems  to  be  a  consensus  that  the  so  called  Part  B  of  the  Plan  is  not  required  any  more. 

 However,  current    9.2  states  that  all  the  frequency  assignments  associated  with  existing  systems  would  have  to  cease  operation  20  years  after  the  entry  into  force  of  the  Plan,  i.  e.  16  March  2010.  In  this  respect, 
 the  output  of  the  SC-  WP  December  2005  meeting  recognizes  that  it  would  be  neither  appropriate  nor  practical  to  abruptly  discontinue  on  this  date  the  operation  of  all  existing  systems  in  the  List,  in 
 particular  those  in  which  either  the  uplink  or  downlink  stands  from  an  additional  use  or  other  networks  in  unplanned  bands. 
 The  proposal  presented  below  treats  existing  systems  as  suggested  in  Annex  2  of  the  output  of  the  SC-  WP  December  meeting.  By  not  distinguishing  assignments  in  the  List  that  are  associated  with  existing 

 4  For  instance  as  considered  in  Annex  2  of  Doc.  4A/  277  (output  from  the  Working  Party  of  the  Special 
 Committee,  WP-  SC,  December  2005  meeting,  on  WRC-  07  Agenda  Item  1.10)  or  as  currently  contained  in  the  procedures  of  Appendices  30  and  30A  of  the  Radio  Regulations.

 87 
 systems  from  those  that  stem  from  allotments  or  from  subregional  systems,  the  concept  of  existing  systems  can  be  eliminated  and  continuity  of  their  operation  can  be  ensured. 
 Subregional  Systems  and  Additional  Uses 
 Subregional  systems  were  introduced  in  the  procedures  of  Appendix  30B  in  order  to  allow  neighboring  countries  to  combine  their  allotments  into  a  system  with  regional  coverage.  For  this  reason,  the 

 submission  of  subregional  systems  in  the  current  regulations  contemplates  the  possibility  of  suspending  allotments  of  the  Member  States  participating  in  the  system.  However,  up  to  now  the  submissions  for 
 subregional  systems  have  never  included  requests  for  suspension  or  partial  suspension  of  allotments.  Therefore,  subregional  systems  have  actually  been  implemented  as  additional  uses  in  the  sense  that  they 
 will  coexist  with  allotments  and  assignments  in  the  same  way  additional  uses  do. 
 Given  all  the  above,  there  is  no  reason  for  the  distinction  between  these  two  types  of  use  of  Appendix  30B  frequencies  and  in  the  proposals  below  these  two  categories  are  merged  into  one  category,  referred  to  as 

 additional  uses. 
 Currently,  the  main  distinctions  between  the  two  categories  are  :  (i)  subregional  systems  can  explore  the  PDA  concept  and  additional  uses  cannot  ;  (ii)  frequency  assignments  of  subregional  systems  have  an 

 unlimited  period  of  validity  while  those  of  additional  uses  are  limited  to  15-  year  period  of  validity.  In  the  proposals  below  the  distinction  with  respect  to  the  application  of  the  PDA  is  not  relevant  since  this 
 concept  is  being  eliminated  while  the  period  of  validity  of  frequency  assignments  of  the  new  category  of  additional  uses  would  not  be  limited. 

 Multinational  Service  Areas  Currently,    2.6  of  Appendix  30B  limits  the  service  area  associated  with  additional  uses  to  the  national 
 territory  of  the  administration  submitting  the  additional  use  unless  otherwise  agreed.  The  Rule  of  Procedure  of    2.6  states  that  additional  uses  may  have  multinational  service  areas  if  agreement  from 
 other  administrations  included  in  the  service  area  are  obtained.  It  is  being  proposed  here  that  assignments  resulting  from  modifications  of  allotments  or  submitted  as  additional  uses  can  have  multinational  service 
 areas.  It  is  noted  that  if  an  administration  A  has  its  territory  included  in  the  service  area  of  an  additional  use  proposed  by  another  administration: 

 (i)  Any  allotments  or  assignments  of  Administration  A  are  protected  because  a  submission  requesting  the  use  of  Appendix  30B  frequencies  for  an  additional  use  has  to  be 
 compatible  with  allotments,  assignments  in  the  List  and  assignments  for  which  complete  information  has  been  received  by  the  BR; 

 (ii)  Terrestrial  systems  in  the  territory  of  administration  A  are  protected  by  the  power-  flux  density  limits  of  Article  21  of  the  Radio  Regulations; 
 (iii)  Any  emission  from  the  territory  of  administration  A  intended  for  reception  at  the  space  station  under  consideration  has  to  be  authorized  by  this  administration  and  the  provision 
 of  service  through  the  deployment  of  receive  earth  stations  in  the  territory  of  administration  A  can  only  occur  with  its  approval.

 Geneva,  1988.  Reasons:  The  United  States  supports  the  objectives  stated  in  Article  1  and  the  definition  in  2.1. 

 USA/  /02  MOD  2.2  2.2  Plan:  The  Plan  for  the  fixed-  satellite  service  in  the  frequency  bands  contained  in  this 
 Appendixconsisting  of  two  parts: 
 a)  Part  A,  containing  the  national  allotments; 
 b)  Part  B,  containing  the  networks  of  existing  systems. 
 Reasons:  Existing  systems  are  associated  with  FSS  satellite  networks  that  had  already  been  submitted  to  the  ITU  BR  when  the  Plan  was  developed.  By  now,  the  frequency  assignments  in  these  networks  have 

 either  been  brought  into  use  and  become  assignments  in  the  List  or  have  been  cancelled.  Therefore  there  is  no  need  for  keeping  the  concept  of  Part  B  of  the  Plan. 

 USA/  /03  MOD  2.3  2.3  Allotment:  For  the  purpose  of  this  Appendix,  an  allotment  comprises: 
   a  nominal  orbital  position;    a  bandwidth  of  800  MHz  (up-  link  and  down-  link)  in  the  frequency  bands  listed  in  Article 
 3  of  this  Appendix;    a  service  area  for  national  coverage. 
   generalized  parameters  as  defined  in  Annex  1  to  this  Appendix;    a  predetermined  arc  (PDA). 
88
 89 
 Reasons:  The  generalized  parameters  are  not  considered  to  be  necessary  since  examination  of  the  compatibility  of  any  proposed  assignment  with  allotments  in  the  Plan  or  assignments  in  the  List  can  be 
 conducted  without  calculating  such  parameters.  As  discussed  and  justified  in  connection  with  Article  6  below,  a  non-  sequential  processing  of  submissions  is  being  proposed  here  and  such  approach  is  not 
 compatible  with  retention  of  the  PDA  concept. 

 USA/  /04  SUP  2.4  2.4  Existing  systems:  Those  satellite  systems,  in  the  frequency  bands  covered  by  this 
 Appendix:  a)  which  are  recorded  in  the  Master  International  Frequency  Register  (MIFR);  or 
 b)  for  which  the  coordination  procedure  has  been  initiated;  or  c)  for  which  the  information  relating  to  advance  publication  was  received  by  the  Radiocommunication 
 Bureau  before  8  August  1985,  and  which  in  all  cases  are  listed  in  Part  B  of  the  Plan. 
 Reasons:  As  noted  in  connection  with  USA/  /02  MOD,  existing  systems  are  either  assignments  in  the  List  or  have  been  cancelled.  As  discussed  with  respect  to  No.  9.2  below,  assignments  in  the  List  that  are 
 associated  with  existing  systems  should  not  be  distinguished  from  any  other  assignments  in  the  List  and,  as  a  consequence,  there  is  no  need  to  define  existing  systems. 

 USA/  /05  SUP  2.52.5  Subregional  systems:  For  the  purpose  of  the  application  of  the  provisions  of  this 
 Appendix,  a  subregional  system  is  a  satellite  system  created  by  agreement  among  neighbouring  countries  Member  States  of  the  ITU  or  their  authorized  telecommunications  operating  agencies 
 and  intended  to  provide  domestic  or  subregional  services  within  the  geographical  areas  of  the  countries  concerned 

 USA/  /06  MOD  2.6  2.6  Additional  use:  For  the  application  of  the  provisions  of  this  Appendix,  additional  uses  shall  be  those 
 of  an  administration:  be  those  associated  with  submissions  for  use  of  Appendix  30B  frequencies  that  do  not  involve  the  conversion  of  an  allotment  into  an  assignment  with  or  without  modifications  to  the 
 characteristics  of  the  allotment.  Therefore,  additional  uses  correspond  to  the  use  of  capacity  (orbit/  spectrum  resources)  beyond  that  in  the  Plan.  Submissions  for  additional  uses  may  also  be  made  by 
 a  number  of  administrations  with  one  among  them  designated  as  the  notifying  administration. 
 a)  which  has  a  requirement  whose  characteristics  differ  from  those  used  in  the  preparation  of  Part  A  of  the  Plan;  any  such  requirement  shall  be  limited  to  the  national  coverage,  taking 

 into  account  technical  constraints,  of  the  administration  concerned,  unless  otherwise  agreed.  Additionally,  such  requirement  can  be  met  only  if  the  allotment  of  the  interested  administra-tion, 
 or  part  of  this  allotment,  has  been  converted  into  an  assignment,  or  if  the  requirement  cannot  be  met  by  the  conversion  of  the  allotment  into  an  assignment; 

 b)  which  requires  the  use  of  all  or  part  of  its  national  allotment  that  has  been  suspended  in  accordance  with    6.  54  of  Article  6; 
 c)  which  intends  to  participate  in  a  subregional  system  using  the  procedures  of  Section  III  of  Article  6,  instead  of  using  the  procedures  of  Section  II  thereof. 
 Reasons:  The  concepts  of  subregional  systems  and  additional  uses  have  been  introduced  in  the  Appendix  30B  Plan  with  different  motivations.  In  particular,  subregional  systems  intended  to  allow  neighboring 
 countries  to  combine  their  allotments  into  a  system  with  regional  coverage.  For  that  reason,  the  possibility  of  suspending  allotments  was  associated  with  subregional  systems.  However,  up  to  now  the 
 submissions  for  subregional  systems  have  never  included  requests  for  suspension  or  partial  suspension  of 
89
 90 
 allotments  in  application  of  and  such  submissions  have  been  implemented  in  a  way  that  does  not  affect  allotments  in  the  Plan  or  assignments  in  the  List.  Therefore,  subregional  systems  have  actually  been 
 implemented  as  additional  uses  in  the  sense  that  they  will  coexist  with  allotments  and  assignments  as  additional  uses  do.  In  view  of  the  above,  it  is  proposed  to  eliminate  the  category  of  subregional  systems 
 and  to  have  a  simplified  definition  for  additional  uses,  capable  of  accommodating  requirements  being  currently  met  by  the  two  existing  categories.

 information  not  provided. 
 6.4.  Upon  receipt  of  a  complete  (Appendix  4)  notice  relating  to  the  proposed  assignment,  the  Bureau  shall  examine  each  notice  as  to  its  conformity  with  the  Table  of  Frequency 
 Allocations  and  the  other  provisions  7  of  these  Regulations,  except  those  provisions  relating  to  conformity  with  the  fixed-  satellite  service  Plan. 

 6.5.  When  the  examination  of  all  or  parts  of  the  notice  with  respect  to    6.4  leads  to  an  unfavourable  finding,  the  relevant  part  of  the  notice  shall  be  returned  to  the  notifying 
 administration  with  an  indication  of  the  appropriate  action. 
 6.6.  When  the  examination  of  all  or  parts  of  the  notice  with  respect  to    6.3  leads  to  a  favourable  finding,  the  Bureau  shall  use  the  method  of  Annex  4,  with  respect  to  the  relevant  part  of  the 
 notice  to  determine  administrations  whose 
 -  allotments  in  the  Plan; 
 -  assignments  which  appear  in  the  List; 
 -  assignments  for  which  the  Bureau  has  previously  received  complete  information  in  accordance  with  this  Article; 

 are  considered  as  being  affected. 
 6.7.  The  Bureau  shall  publish,  in  a  Special  Section  of  its  International  Frequency  Information  Circular  (BR  IFIC),  the  complete  information  received  under    6.1,  together  with  the  names 

 of  the  affected  administrations  and  the  corresponding  allotments  in  the  Plan,  assignments  in  the  List  and/  or  assignments  for  which  the  Bureau  has  previously  received  complete 
 information  in  accordance  with  this  Article.  The  Bureau  shall  immediately  send  the  results  of  its  examination  to  the  administration  proposing  the  assignment. 

 6.8.  The  Bureau  shall  send  a  telegram/  fax  to  the  administrations  listed  in  the  Special  Section  of  the  BR  IFIC  drawing  their  attention  to  the  information  it  contains  and  shall  send  them  the  results 
 of  its  examination. 
 6.9.  Comments  from  administrations  on  the  information  published  pursuant  to    6.7  shall  be  sent  to  the  administration  proposing  the  assignment  with  a  copy  to  the  Bureau. 

 6.10.  An  administration  which  considers  that  it  should  have  been  identified  in  the  publication  referred  to  under    6.7  above  shall,  within  four  months  of  the  date  of  publication  of  its  relevant  BR 
 IFIC,  and  identifying  the  affected  allotment,  assignment  or  proposed  assignment,  request  the  Bureau  to  include  its  name  in  the  publication.  The  Bureau  shall  study  this  information  on  the 
 basis  of  Annex  4  and  shall  inform  both  this  administration  and  the  administration  proposing  the  assignment  of  its  conclusions.  Should  the  Bureau  agree  to  the  administration's  request,  it 
 shall  publish  an  addendum  to  the  publication  under    6.7. 
 6.11.  An  administration  that  has  not  notified  its  comments  either  to  the  administration  seeking  agreement  or  to  the  Bureau  within  a  period  of  four  months  following  the  date  of  its  BR  IFIC 

 referred  to  in    6.7  shall  be  deemed  to  have  agreed  to  the  proposed  assignment. 
 6.12.  Thirty  days  prior  to  the  expiry  of  the  same  four-  month  period,  the  Bureau  shall  dispatch  a  reminder  telegram  or  fax  to  an  administration  which  has  not  made  its  comments  under    6.9, 

 bringing  the  matter  to  its  attention. 
 7  The  other  provisions  shall  be  identified  and  included  in  the  Rules  of  Procedure. 
94
 95 
 6.13.  After  expiry  of  the  deadline  for  comments  in  respect  of  the  proposed  assignment,  the  Bureau  shall,  according  to  its  records,  publish  a  Special  Section  indicating  the  list  of  administrations 
 whose  agreements  are  required  for  completion  of  the  Article  6  procedure. 
 6.14.  If  no  comments  have  been  received  on  the  expiry  of  the  four-  month  period  specified  in    6.10  and  6.11,  or  if  agreement  has  been  reached  with  the  administrations  which  have  made 

 comments  and  with  which  agreement  is  necessary,  the  administration  proposing  the  new  or  modified  assignment  may  request  the  Bureau  to  have  the  assignment  entered  into  the  List, 
 indicating  the  final  characteristics  of  the  frequency  assignment  together  with  the  names  of  the  administrations  with  which  agreement  has  been  reached.  For  this  purpose,  it  shall  send  to  the 
 Bureau  the  information  specified  in  Appendix  4.  In  submitting  the  notice,  the  administration  may  request  the  Bureau  to  examine  the  notice  simultaneously  under    6.16  (entry  into  the 
 List)  and    8.8,  8.9  (notification). 
 6.15.  If  the  information  received  by  the  Bureau  under    6.14  is  found  to  be  incomplete,  the  Bureau  shall  immediately  seek  from  the  administration  concerned  any  clarification  required  and 

 information  not  provided  8  . 
 6.16.  Upon  receipt  of  a  complete  (Appendix  4)  notice  relating  to  the  proposed  assignment  under    6.14,  the  Bureau  shall  determine  whether  the  this  Appendix  4  submission  is  identical  to  the 

 initial  notice.  If  this  is  the  case,  the  submission  under    6.14  will  be  treated  as  specified  in    6.20.  However,  if,  in  seeking  agreement,  an  administration  modifies  its  initial  notice,  the 
 Bureau  shall  conduct  the  examination  described  in    6.17  through    6.19. 
 6.17.  The  Bureau  shall  examine  the  Appendix  4  information  received  under    6.14  with  respect  to  its  conformity  to  the  Table  of  Frequency  Allocations  and  the  other  provisions  9  of  these 

 Regulations,  except  those  provisions  relating  to  conformity  with  the  fixed-  satellite  service  Plan. 

 6.18.  When  the  examination  of  all  or  parts  of  the    6.14  submission  with  respect  to    6.17  leads  to  an  unfavourable  finding,  the  relevant  part  of  the  notice  shall  be  returned  to  the  notifying 
 administration  with  an  indication  of  the  appropriate  action. 
 6.19.  When  the  examination  of  all  or  parts  of  the  modifications  with  respect  to    6.17  leads  to  a  favourable  finding,  the  Bureau  shall  use  the  method  of  Annex  4  with  respect  to  the  relevant 

 part  of  the  notice  to  identify  administrations  for  which  agreement  has  not  been  already  obtained  whose 

 -  allotments  in  the  Plan; 
 -assignments  which  appear  in  the  List; 
 -assignments  for  which  the  Bureau  has  previously  received  complete  information  in  accordance  with  this  Article; 

 8  If  the  payments  are  not  received  in  accordance  with  the  provisions  of  Council  Decision  482,  as 
 amended,  on  the  implementation  of  cost  recovery  for  satellite  network  filings,  the  Bureau  shall  cancel  the  publication,  after  informing  the  administration  concerned.  The  Bureau  shall  inform  all  administrations  of 

 such  action  and  that  the  network  specified  in  the  publication  in  question  no  longer  has  to  be  taken  into  consideration  by  the  Bureau  and  other  administrations.  The  Bureau  shall  send  a  reminder  to  the  notifying 
 administration,  not  later  than  two  months  prior  to  the  deadline  for  the  payment  in  accordance  with  Council  Decision  482  unless  the  payment  has  already  been  received  (see  also  Resolution  87  (WRC-  03)). 

 9  The  other  provisions  shall  be  identified  and  included  in  the  Rules  of  Procedure.

 are  considered  as  being  affected  by  the  notice  submitted  under    6.14  10  . 
 6.20.  In  the  event  of  a  favourable  finding  with  regard  to  compatibility  under    6.19,  the  Bureau  shall  enter  the  proposed  assignment  in  the  List  and  publish  in  a  Special  Section  to  its  BR  IFIC  the 

 information  received  under    6.14  together  with  the  names  of  any  administrations  identified  under    6.13  and    6.19  with  which  the  provisions  of  this  Article  have  been  successfully 
 applied.  The  administration  proposing  the  assignment  may  then  notify  the  assignment  in  accordance  with  Article  8. 

 6.21.  When  the  examination  under    6.19  leads  to  an  unfavourable  finding,  the  Bureau  shall  publish  in  a  Special  Section  of  its  BR  IFIC  the  information  received  under    6.14  together  with  the 
 names  of  any  administrations  with  which  the  provisions  of  this  Article  have  been  successfully  applied  as  well  as  the  administrations  with  which  they  have  not. 

 6.22.  After  addressing  the  remaining  coordination  requirements  identified  under    6.21,  the  administration  proposing  the  new  or  modified  assignment  may  request  the  Bureau  to  have  the 
 assignment  entered  into  the  List,  indicating  the  final  characteristics  of  the  frequency  assignment  together  with  the  names  of  the  administrations  with  which  agreement  has  been 
 reached.  For  this  purpose,  it  shall  send  to  the  Bureau  the  information  specified  in  Appendix  4.  In  submitting  the  notice,  the  administration  may  request  the  Bureau  to  examine  the  notice 
 simultaneously  for  entry  into  the  List  and  for  notification  (  8.8,  8.9). 
 6.23.  The  Bureau  will  then  conduct  the  examination  specified  in    6.15  and    6.16  (comparing  the  Appendix  4  submission  under  examination  with  that  previously  submitted  under    6.14  or   

 6.22).  If  necessary,  examination  under    6.17  through    6.19  is  then  conducted. 
 6.24.  After  a  notice  is  published  under    6.21,  should  the  notifying  administration  resubmit  the  notice  and  insist  upon  its  reconsideration,  the  Bureau  shall  enter  the  assignments  provisionally  in  the 

 List  with  an  indication  of  those  administrations  whose  assignments  were  the  basis  of  the  unfavourable  finding  11  .  The  entry  shall  be  changed  from  provisional  to  definitive  recording  in 
 the  List  only  if  the  Bureau  is  informed  that  the  new  assignment  has  been  in  use,  together  with  the  assignments  which  were  the  basis  for  the  unfavourable  finding,  for  at  least  four  months 
 without  any  complaint  of  harmful  interference  being  made  or  if  the  assignments  which  were  the  basis  for  the  unfavourable  finding  are  cancelled. 

 6.25.  When  an  assignment  is  entered  provisionally  in  the  List  under  the  provisions  of    6.24,  the  Bureau  shall  not  update  the  reference  situation  for  the  Plan  and  the  List  until  the  recording  is 
 changed  to  definitive  in  accordance  with    6.24. 
 6.26.  Should  harmful  interference  be  caused  by  an  assignment  included  in  the  List  under    6.24  to  any  assignment  in  the  List  which  was  the  basis  of  the  disagreement,  the  administration  using  the 

 frequency  assignment  included  in  the  List  under    6.24  shall,  upon  receipt  of  advice  thereof,  immediately  eliminate  this  harmful  interference. 

 10  The  allotments  in  the  Plan,  assignments  in  the  List  and  assignments  with  complete  information 
 previously  submitted  are  those  that  had  been  identified  as  such  at  the  date  of  receipt  of  the  initial  submission  under    6.1  of  the  assignment  under  examination,  i.  e.  examination  under    6.19  is  conducted 

 with  respect  to  the  same  reference  situation  previously  used  for  the  examination  under    6.1. 
 11  The  entry  shall  be  definitive  in  the  case  of  a  frequency  assignment  to  a  receiving  station,  under  the 

 condition  that  the  notifying  administration  has  undertaken  that  no  complaint  will  be  made  in  respect  of  any  harmful  interference  which  may  be  caused  to  that  assignment  by  the  assignment  which  was  the  basis 

 for  the  unfavourable  finding. 
96
 97 
 6.27.  When  a  frequency  assignment  included  in  the  List  is  no  longer  required,  the  notifying  administration  shall  immediately  inform  the  Bureau. 
 6.28.  The  date  of  bringing  into  use  of  a  frequency  assignment  may  be  extended  by  the  notifying  administration  up  to  no  more  than  eight  years  from  the  date  of  receipt  by  the  Bureau  of  the 
 complete  Appendix  4  information  under    6.1. 
 6.29.  Any  frequency  assignment  that  -  is  no  longer  required,  as  per  information  provided  by  the  notifying  administration  to  the 

 BR  in  accordance  with    6.27;  or  -  has  not  been  brought  into  use  within  the  period  specified  in    6.28 
 shall  be  canceled  by  the  BR. 
 6.30.  Assignments  canceled  under    6.29  that  result  from  the  conversion  of  an  allotment  (with  or  without  modifications  to  the  characteristics  of  the  allotment)  shall  be  transferred  back  to  the 
 Plan  without  any  changes  to  the  technical  parameters  or  orbital  location  that  they  had  in  the  List  in  the  case  of  a  definitive  recording  and  shall  be  transferred  back  to  the  Plan  with  the 
 characteristics  of  the  original  allotment  in  the  case  of  a  provisional  entry  in  the  List. 
 6.31.  After  taking  the  action  described  in    6.29,  the  BR  shall  update  the  reference  situation  of  all  allotments  in  the  Plan  and  assignments  in  the  List,  as  appropriate. 

 6.32.  The  procedure  of  this  Article  may  be  applied  by  the  administration  of  a  new  ITU  Member  State  in  order  to  include  a  new  assignment  in  the  List  over  its  national  territory.  The  next 
 World  Radiocommunication  Conference  may  then  be  requested  to  consider  the  inclusion  in  the  Plan  of  a  new  allotment  over  the  national  territory  of  the  new  Member  State  with  the 
 characteristics  of  its  assignment  that  has  entered  the  List  after  successful  completion  of  the  procedure  described  here. 

 6.33.  Should  the  assignments  mentioned  in    6.32  over  the  national  territory  of  the  administration  not  be  brought  into  use  within  the  regulatory  time-  limit  specified  in    6.28,  they  would  be 
 retained  in  the  List  until  the  end  of  the  World  Radiocommunication  Conference  immediately  following  the  successful  completion  of  the  procedure  referred  to  in    6.32,  and  thereafter  they 
 shall  be  removed  from  the  List. 
 6.34.  An  administration  may,  at  any  stage  in  the  procedure  described  in  this  Article,  or  before  applying  it,  request  the  assistance  of  the  Bureau. 
 Reasons:  The  changes  proposed  in  Article  6  incorporate  the  key  points  discussed  in  the  Background  Information  section.  In  particular,  for  the  reasons  discussed  therein  the  proposed  Article  6  is  consistent 
 with  a  non-  sequential  processing  of  submissions  with  no  distinction  made  between  the  current  categories  of  subregional  systems  and  additional  uses.

   6.1  THROUGH    6.23  DEFINE  HOW  SUBMISSIONS  FOR  USE  OF  APPENDIX  30B  FREQUENCIES  ARE  TO  BE  PROCESSED.  THIS  PROCEDURE  IS  CONSIDERED  TO  BE 
 APPROPRIATE  AND  IS  SIMILAR  TO  THAT  CURRENTLY  USED  IN  APPENDICES  30  AND  30A. 

   6.24  THROUGH    6.26  OPEN  THE  POSSIBILITY  OF  PROVISIONAL  ENTRY  IN  THE  LIST.  IT  IS  IMPORTANT  THAT  THIS  FLEXIBILITY  BE  INTRODUCED  TO  PREVENT 
 THAT  ASSIGNMENTS  THAT  MAY  NEVER  BE  BROUGHT  INTO  USE  UNDULY  BLOCK  THE  IMPLEMENTATION  OF  ASSIGNMENTS  THAT  WOULD  OTHERWISE  BE 
 IMPLEMENTED.  IN    6.24  THROUGH    6.26,  PROVISIONAL  ENTRY  IN  THE  LIST  HAS  BEEN  LIMITED  TO  THE  CASES  IN  WHICH  THE  ASSIGNMENTS  THAT  WERE  THE 
 BASIS  FOR  THE  UNFAVOURABLE  FINDING  BE  ADDITIONAL  USES  IN  THE  LIST  OR  SUBMITTED  NOTICES  FOR  ADDITIONAL  USES.  BY  DOING  THIS,  IT  IS  ENSURED 
 THAT  PROVISIONAL  ENTRIES  IN  THE  LIST  MAY  BE  INCOMPATIBLE  WITH  ALLOTMENTS  OR  ASSIGNMENTS  RESULTING  FROM  THE  CONVERSION  OF 
 ALLOTMENTS.  THIS  APPROACH  PROVIDES  A  REASONABLE  BALANCE  BETWEEN  THE  INTERESTS  OF  ITU  MEMBER  STATES  THAT  WANT  TO  IMPLEMENT  THEIR 
 ALLOTMENTS  AND  THOSE  OF  ADMINISTRATIONS  THAT  WANT  TO  USE  CAPACITY  (ORBIT/  SPECTRUM  RESOURCES)  BEYOND  THAT  IN  THE  PLAN. 
   6.29  through    6.31  address  the  cancellation  of  assignments.  In  particular,    6.30  proposes  that  in  the  case  of  assignments  resulting  from  the  conversion  of  allotments, 
 cancelled  assignments  will  be  transferred  to  the  Plan  in  a  way  that  does  disrupt  the  current  reference  situation. 

   6.32    6.33  propose  that,  similarly  to  the  treatment  given  in  Appendix  30  and  30A  for  Regions  1  and  3,  new  ITU  Member  States  can  use  the  provisions  of  Article  6  to  have  allotments  (with 
 national  coverage)  included  in  the  Plan.

 national  allotment  in  Part  A  of  the  Plan  by  the  following  procedure.  7.2  The  administration  shall  submit  its  request  for  an  allotment  to  the  Bureau,  with  the  following 
 information: 
 a)  the  geographical  coordinates  of  not  more  than  10  test  points  for  determining  the  minimal  ellipse  to  cover  its  national  territory; 

 b)  the  height  above  sea  level  of  each  of  its  test  points  and  the  rain  zone  or  zones;

 7.3  Upon  receipt  of  the  complete  information  (mentioned  in    7.2  above),  the  Bureau  shall  find  an  appropriate  orbital  position,  if  necessary  using  the  PDA  concept,  and  shall  enter  the  national  allotment  of 
 the  new  Member  State  of  the  Union  in  Part  A  of  the  Plan.  7.4  For  this  purpose  the  Bureau  shall  consult,  and  if  necessary  seek  the  agreement  of,  any 
 administrations  that  may  be  affected.

 USA/  /23  MOD  9.1  9.1  Part  A  of  tThe  Plan  is  limited  to  national  systems  providing  a  domestic  service.  Administrations 
 may,  however,  in  accordance  with  the  provisions  of  Section  II  of  Article  6,  use  all  or  part  of  modify  their  allotments  or  propose  additional  uses  to  provide  multi-  national  servicesform  a  subregional  system. 
 Reasons:  Changes  are  consequential  of  those  introduced  in  Article  6. 

 USA/  /24  SUP  9.2  9.2  The  existing  systems  listed  in  Part  B  of  the  Plan  may  continue  in  operation  for  a  maximum  period 
 of  20  years  from  the  date  of  entry  into  force  of  this  Appendix. 
 Reasons:  Existing  systems  are  associated  with  FSS  satellite  networks  that  had  already  been  submitted  to  the  ITU  BR  when  the  Plan  was  developed.  By  now,  the  frequency  assignments  in  these  networks  have 

 either  been  brought  into  use  and  become  assignments  in  the  List  or  have  been  cancelled. 
 Current    9.2  means  that  all  these  frequency  assignments  would  have  to  cease  operation  (or  operate  under  No.  4.4  of  the  Radio  Regulations)  after  16  March  2010.  Operation  under  No.  4.  4  is  not  a  realistic  option, 

 at  least  as  Appendix  30B  frequencies  are  more  widely  used.  Moreover,  requiring  that  operational  satellite  networks  with  large  number  of  users  cease  abruptly  their  operation  is  unreasonable. 

 By  suppressing    9.2,  frequency  assignments  of  existing  systems  that  have  been  brought  into  use  just  remain  in  the  List  similarly  to  the  way  in  which  frequency  assignments  associated  with  subregional 
 systems  are  currently  treated.

 ANNEX  3A 
 Criteria  for  determining  when  proposed  assignments  are  considered  as  being  in  conformity  with  the  Plan 

 In  this  method,  the  generalized  parameters  are  calculated  (see  Annex  1,  Section  B),  and  the  results  are  compared  with  the  corresponding  reference  set: 
   If  the  calculated  A,  B,  C  and  D  values  are  less  than  or  equal  to  the  relevant  reference  set,  then  the  use  of  the  assignment  is  considered  to  be  in  conformity  with  the  Plan. 
   If  the  calculated  values  of  A  or  C  are  greater  than  the  relevant  reference  set,  the  use  of  the  assignment  is  considered  not  to  be  in  conformity  with  the  Plan. 
   If  the  calculated  values  of  B  or  D  are  greater  than  the  relevant  reference  set,  the  assignment  is  protected  only  to  the  level  of  the  relevant  reference  set. 

 ANNEX  3B 
 Macrosegmentation  concept  In  this  method,  an  administration  shall  not  be  required  to  coordinate  if,  in  addition  to  meeting  the 
 conditions  of  Annex  3A,  the  proposed  frequency  assignments  are  ordered  in  such  a  way  that  the  upper  60%  of  each  allotment  band  is  used  for  high-  density  carriers  and  the  lower  40%  for  low-  density  carriers. 
103
 104 
 For  the  purposes  of  this  annex,  the  term  high-  density  carriers  shall  be  used  for  those  carriers  whose  ratio  of  power  spectral  density  peak  (averaged  over  the  worst  4  kHz)  to  average  (defined  over  the 
 necessary  bandwidth  of  the  modulated  carrier)  is  greater  than  5  dB;  and  the  term  low-  density  carriers  shall  be  used  for  those  for  which  this  ratio  is  less  than  5  dB. 

 Reasons:  Suppression  of  Annexes  3A  and  3B  is  consequential  of  the  proposed  elimination  of  the  generalized  parameters  (see  USA/  /03  MOD  and  USA/  /29  SUP  above).  The  concept  of 
 segregating  "high  density  carriers"  from  "low  density  carriers"  is  still  maintained  in  Annex  6,  item  2.

 criteria  set  out  in    1.1  below.  1.1  For  the  purposes  of  this  Annex,  an  administration  will  be  considered  as  being  affected  by  another 
 administration  if,  at  its  nominal  orbital  position  within  the  predetermined  arc,  the  calculated  single-  entry  C/  I  is  less  than  or  equal  to  30  dB  (WRC-  03  decided  that  for  the  examination  of  submissions  received  as 
 from  5  July  2003  the  value  27  dB  (instead  of  30  dB)  shall  be  applied),  or  the  calculated  value,  based  on  the  Plan,  due  to  that  other  administration  (whichever  is  lower),  at  any  test  point  within  the  service  area  of

 based  on  the  Plan,  due  to  that  other  administration  (whichever  is  lower),  an  administration  shall  be  considered  as  being  affected  if  the  overall  aggregate  C  /  I,  calculated  by  the  method  in  Appendix  1  to 
 Annex  4,  falls  below  26  dB  9  (WRC-  03  decided  that  for  the  examination  of  submissions  received  as  from  5  July  2003  the  value  23  dB  (instead  of  26  dB)  shall  be  applied),  or  the  value  for  the  assignment

 is  improved  in  the  latter  application  of  this  procedure,  the  improved  value  will  be  used  until  it  reaches  26  dB  (WRC-  03  decided  that  for  the  examination  of  submissions  received  as  from  5  July  2003  the  value

 a)  the  order  of  all  satellites  and  also  the  position  of  satellites  in  the  design  or  operational  stages  shall  be  fixed  so  as  to  minimize  the  impact  on  these  systems.  Next,  the  nominal 

 positions  of  pre-  design  systems  shall  be  adjusted  so  as  to  compensate  for  the  degraded  C  /  I.  The  adjustments  of  nominal  positions  shall  be  limited  to  the  range  of  their  respective 
 predetermined  arcs; 
 b)  if  compatibility  is  not  obtained  through    1.2  a),  the  ordering  of  allotments  of  satellites  in  the  pre-  design  stage  shall  be  subject  to  change  within  their  predetermined  arcs,  as  defined 

 in  Article  5; 
 c)  if  the  C  /  I  objectives  are  not  achieved,  the  affected  administration  may  at  this  stage  opt  to  select  other  measures  than  repositioning,  as  described  in    1.2  d)  below; 

 d)  if  compatibility  is  not  achieved  under    1.  2  b),  and  if  the  measures  of    1.2  c)  are  unsuccessful,  the  allotment(  s)/  assignment(  s)  subject  to  repositioning  shall  include  the 
 systems  in  the  design  stage,  for  their  predetermined  arc  as  defined  in  Article  5.  1.3  Administrations  for  which  the  criteria  of    1.1  are  not  met  shall  be  identified  for  the  purposes  of

 Coordination  arc  in  the  band  17.3-  17.8  GHz  and  other  closely  related  proposal 
 Background  information:  Resolution  901  (WRC-  03)  invites  ITU-  R  to  conduct  studies  on  the  applicability  of  the  coordination  arc  concept  for  space  radiocommunication  services  not  yet 
 covered  by  these  Regulations  as  well  as  to  recommend,  as  appropriate,  the  orbital  separation  required  for  triggering  inter-  service  and  intra-  service  coordination  concerning  the  satellite 
 services  in  frequency  bands  above  3.4  GHz  for  geostationary-  satellite  (GSO)  networks  not  subject  to  a  Plan  and  not  already  covered  by  the  coordination  arc  concept  specified  in  No.  9.7 
 (GSO/  GSO)  of  Table  5-  1  (Appendix  5),  under  items  1),  2)  and  3)  of  the  frequency  band  column,  and  subject  to  Section  II  of  Article  9.  This  Resolution  further  resolves  to  recommend  that  a 
 future  competent  conference  review  the  results  of  ITU-  R  studies  on  the  application  of  the  coordination  arc  and  consider  including  the  results  of  these  studies  in  Appendix  5.  Review  of 
 such  study  results  are  considered  under  Resolution  86  of  Agenda  Item  1.12. 
 Pursuant  to  Resolution  901,  ITU-  R  studied  the  appropriate  coordination  arc  value  to  trigger  coordination  between  Broadcasting-  Satellite  Service  (BSS)  networks  serving  Region  2  in  the 
 band  17.3-  17.8  GHz  and  Fixed  Satellite  Service  (FSS)  (space-  to-  Earth)  networks  serving  Region  1  in  the  band  17.3-  17.7  GHz  and  FSS  (space-  to-  Earth)  networks  serving  Regions  1,  2  and  3  in 
 the  band  17.7-  17.8  GHz. 
 The  ITU-  R  studies  concluded  that  a  coordination  arc  value  of  8  is  appropriate  to  trigger  coordination  between  GSO  BSS  networks  serving  Region  2  and  GSO  FSS  (space-  to-  Earth) 
 networks  whose  service  areas  are  limited  to  Region  1  in  the  band  17.3-  17.7  GHz  and  between  GSO  BSS  networks  serving  Region  2  and  GSO  FSS  (space-  to-  Earth)  networks  whose  service 
 areas  are  limited  to  Regions  1  and/  or  3  in  the  band  17.7-  17.8  GHz.  As  a  result,  specific  changes  are  proposed  to  Table  5-  1  of  Appendix  5  to  incorporate  these  conclusions. 
 For  the  case  of  Region  2  FSS  (space-  to-  Earth)  with  respect  to  Region  2  BSS  in  the  17.7    17.8  GHz  band  footnote  No.  5.517  applies. 

 5.517  In  Region  2,  the  allocation  to  the  broadcasting-  satellite  service  in  the  band  17.3-  17.8  GHz  shall  come  into  effect  on  1  April  2007.  After  that  date,  use  of  the  fixed-  satellite  (space-  to-Earth) 
 service  in  the  band  17.7-  17.8  GHz  shall  not  claim  protection  from  and  shall  not  cause  harmful  interference  to  operating  systems  in  the  broadcasting-  satellite  service. 

 Changes  to  the  wording  of  this  provision,  as  well  as  consequential  changes  to  the  Table  of  Allocations  are  proposed  recognizing  that  the  1  April  2007  date  has  passed.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 WRC-  07  Agenda  Item  2:  to  examine  the  revised  ITU-  R  Recommendations  incorporated  by  reference  in  the  Radio  Regulations  communicated  by  the  Radio  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  the  principles  contained  in  Resolution  27 
 (WRC-  03). 
 Background  Information:  Agenda  Item  1.15  of  WRC-  03  dealt  with  RNSS  matters  as  indicated  in  Resolutions  604  (WRC-  00),  605  (;  WRC-  00),  and  Resolution  606  (WRC-  00). 
 Resolution  605  concerned  the  development  and  implementation  of  regulations  to  provide  protection  for  the  ARNS  in  the  band  1164-  1215  MHz  from  all  the  emissions  of  real  RNSS  systems  in  the  band.  To 
 this  end  No.  5.328A  was  adopted  and  is  associated  with  the  referenced  allocation.  It  states: 
 5.328A  Stations  in  the  radionavigation-  satellite  service  in  the  band  1164-  1215  MHz  shall  operate  in  accordance  with  the  provisions  of  Resolution  609  (WRC-  03)  and  shall  not  claim  protection  from  stations 
 in  the  aeronautical  radionavigation  service  in  the  band  960-  1215  MHz.  No.  5.43A  does  not  apply.  The  provisions  of  21.18  shall  apply. 

 The  language  of  this  footnote  regulation  mandates  that  the  RNSS  in  the  band  1164-  1215,  shall  operate  in  accordance  with  the  provisions  of  Resolution  609  (WRC-  03).  This  Resolution  is 
 entitled:  Protection  of  aeronautical  radionavigation  service  systems  from  the  equivalent  power  flux-  density  produced  by  radionavigation-  satellite  service  networks  and  systems  in  the  1164-  1215  MHz 
 frequency  band.  Resolves  10  of  this  mandatory  Resolution  states: 
 10  that  the  methodology  and  the  reference  worst-  case  ARNS  system  antenna  contained  in  Recommendation  ITU-  R  1642  shall  be  used  by  administrations  for  calculating  the  aggregate  epfd 
 produced  by  all  the  space  stations  within  all  RNSS  systems  in  the  band  1164-  1215  MHz. 
 As  indicated  the  statement  shall  be  used  in  relation  to  Recommendation  ITU-  R  1642  clearly  makes  use  of  this  recommendation  mandatory  in  the  context  of  the  Radio  Regulations,  and  therefore  must  be 
 considered  part  of  them. 
 Resolution  27  and  its  Annex  set  forth  the  criteria  for  Recommendations  and  Resolutions  to  be:  Incorporated  by  Reference.  Clearly,  Recommendation  M.  1642  meets  these  criteria. 

 In  consequence  it  is  mandatory  that  this  recommendation  be  considered  as  part  of  Volume  4  of  the  Radio  Regulations  although  it  is  not  now.  Recommendation  ITU-  R  1642  must  be  included  in  subsequent 
 revisions  of  Volume  4  of  the  Radio  Regulations. 
 It  should  be  noted  that  a  Working  Party  of  the  Special  Committee  has  come  to  the  same  conclusion  regarding  the  incorporation  in  volume  4  of  the  Radio  Regulations  of  the  referenced  Recommendation  as 
 reflected  in  the  Attachment  to  Annex  15  of  Document  SC-  WP/  57-  E.

 The  Recommendation  ITU-  R  M.  1642,    Methodology  for  Calculating  the  EPFD  Produced  by  All  Space  Stations  within  all  RNSS  systems  and  networks  in  the  band  1164-  1215  MHz  is  required  to  be  added  to 
 Volume  4  ,  ITU-  R  Recommendations  incorporated  by  reference.  A  copy  of  Recommendation  ITU-  R  M.  1642  will  be  made  available  to  the  Conference  in  accordance  with  the  provisions  of  Annex  3  to 
 Resolution  27. 
 Reason:  Recommendation  ITU-  R  M.  1642  fulfills  all  of  the  criteria  for  a  recommendation  which  is  incorporated  by  reference  as  set  forth  in  Resolution  27  and  its  Annex,  and  therefore  must  be  included  in 
 Volume  4  of  the  Radio  Regulations.

 United  States  of  America  DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 Agenda  Item  1.12:  to  consider  possible  changes  in  response  to  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference:  Advance  publication,  coordination,  notification  and  recording 
 procedures  for  frequency  assignments  pertaining  to  satellite  networks  in  accordance  with  Resolution  86  (WRC-  03); 

 Regulatory  Procedures  and  associated  technical  criteria  applicable  to  satellite  networks  Modification  to  Appendix  7,  Table  10 
 Background  information:  Resolution  86  (Rev.  Marrakesh,  2002)  requested  that  WRC-  03  and  subsequent  Conferences  review  the  regulatory  procedures  associated  with  the  advance  publication, 
 coordination,  notification  and  recording  of  frequency  assignments  pertaining  to  satellite  network.  WRC-03  identified  in  Resolution  86  (WRC-  03)  the  scope  and  the  criteria  to  be  used  for  the  implementation  of 
 Resolution  86  (Rev.  Marrakesh,  2002).  Resolves  1  of  Resolution  86  (WRC-  03)  specifically  states  that  WRC-  07  should  consider  any  proposals  which  deal  with  deficiencies  in  the  advance  publication, 
 coordination,  notification  and  recording  procedures  of  the  Radio  Regulations  (RR)  for  space  services  which  have  either  been  identified  by  the  Board  and  included  in  the  Rules  of  Procedure  or  which  have 
 been  identified  by  administrations  or  by  the  Bureau  as  appropriate. 
 A  review  of  Appendix  7,  Table  10  (Predetermined  coordination  distance)  indicates  that  the  case  of  ground-  based  earth  stations  and  aircraft  terrestrial  stations,  except  for  those  specifically  identified  cases  in 
 the  table,  is  missing.  In  the  past  the  Radiocommunications  Bureau  has  used  the  predetermined  distance  of  500  km  for  this  case,  e.  g.,  see  Document  RRB98/  134(  Rev.  1)  dated  8  December  1998.  This  coordination 
 distance  was  derived  assuming  line-  of-  sight  propagation  between  the  aircraft  and  ground-  based  stations  with  a  4/  3  Earth  radius  and  the  aircraft  altitude  of  12  km.  The  500  km  is  consistent  with  the  distance 
 currently  applicable  to  the  similar  cases  of  coordination  between  aircraft  and  ground-  based  stations  such  as  i)  ground-  based  earth  stations  in  the  bands  below  1  GHz  to  which  No.  9.11A  applies/  ground-  based 
 mobile  in  the  bands  within  the  range  1-  3  GHz  to  which  No.  9.11A  applies  and  aircraft  (mobile)  terrestrial  stations;  ii)  aircraft  (mobile)  earth  stations  and  ground-  based  terrestrial  stations;  and  iii)  non-  GSO  MSS 
 feeder-  link  earth  stations  and  aircraft  (mobile)  terrestrial  stations.  To  cover  the  case  of  ground-  based  earth  stations  and  aircraft  terrestrial  stations,  Table  10  needs  to  be  modified  to  include  this  case  with  a 
 coordination  distance  of  500  km.  The  proposal  the  United  States  makes  here  does  not  apply  to  frequency  bands  already  covered  in  Table  10,  including  all  bands  below  3  GHz.

 Comments  of  IWG-  5  on  Draft  U.  S.  Preliminary  View  from  Exec.  Branch  Agencies  on  WRC-  07  Agenda  Item  4  (Document  IWG-  5/  57) 

 IWG-  5  has  considered  the  elements  of  Document  IWG-  5/  57  that  are  relevant  to  either  regulatory  issues  or  agenda  items  under  IWG-  5s  purview.  It  offers  the  following  comments: 
 1.  With  respect  to  Resolution  27  (Incorporation  by  Reference),  IWG-  5  notes  that  it  is  highlighted  for  possible  modification  to  include  reference  in  Vol  4  of  RR  for  IBR  of  parts  of  recommendations.  IWG-  5 
 believes  that  incorporation  by  reference  is  a  sensitive  topic,  and  that  opening  up  Resolution  27  to  modification  would  be  counter-  productive.  Further,  IWG-  5  notes  that  Resolution  27  already  addresses 
 incorporation  by  reference  of  parts  of  recommendations  (see  resolves  5).  If  there  are  instances  where  Recommendations  are  not  properly  incorporated  by  reference,  or  not  included  in  Volume  4  of  the  Radio 
 Regulations,  this  can  be  corrected  on  a  case-  by-  case  basis  within  the  existing  framework.  Accordingly,  IWG-  5  recommends  that  the  US  preliminary  view  on  this  Resolution  should  be  no  change  (NOC). 

 2.  With  respect  to  Resolution  229  (5  GHz  WAS/  RLANs),  IWG-  5  notes  that  it  is  highlighted  as  requiring  further  analysis  before  a  decision  can  be  made  whether  it  should  be  modified  or  not.  It  is  IWG-  5s 
 understanding  that  the  concerns  with  Resolution  229  have  to  do  with  a  Recommendation  (or  part  of)  that  is  incorporated  by  reference,  but  not  included  in  Volume  4  of  the  Radio  Regulations.  Given  that  WRC-  03 
 reached  a  difficult  compromise  on  how  to  handle  WAS/  RLANs  in  the  5  GHz  bands,  and  that  companies  need  certainty  in  order  to  build  and  implement  equipment  in  these  bands,  IWG-  5  does  not  believe  it 
 would  be  useful  to  open  up  Resolution  229  for  revision.  Accordingly,  IWG-  5  recommends  that  the  US  preliminary  view  on  this  Resolution  should  be  no  change  (NOC).

 Telecommunications  and  Information  Administration  (NTIA): 

 Document  WAC/  091(  27.04.06): 
 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 Agenda  Item  1.12:  to  consider  possible  changes  in  response  to  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference:  Advance  publication,  coordination,  notification  and 
 recording  procedures  for  frequency  assignments  pertaining  to  satellite  networks  in  accordance  with  Resolution  86  (WRC-  03); 

 Coordination  of  the  radionavigation-  satellite  service  (space-  to-  space)  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz 
 Background  Information:  The  scope  and  criteria  to  be  used  for  the  implementation  of  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference  by  future  world 
 radiocommunication  conferences  (WRCs)  is  established  in  Resolution  86  (WRC-  03).  Resolves  1  of  Resolution  86  (WRC-  03)  relates  to  the  consideration  of  proposals  dealing  with  deficiencies  in 
 the  advance  publication,  coordination  and  notification  procedures  of  the  Radio  Regulations  for  space  services,  and  Resolves  2  relates  to  consideration  of  proposals  intended  to  transform  the 
 content  of  the  Rules  of  Procedure  into  regulatory  text. 
 WRC-  2000  added  the  space-  to-  space  direction  to  the  existing  radionavigation-  satellite  service  (RNSS)  (space-  to-  Earth)  allocations  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz,  along 
 with  footnote  5.329A.  WRC-  03  added  footnote  5.328B,  which  applied  coordination  between  two  non-  GSO  RNSS  systems  and  between  non-  GSO  and  GSO  RNSS  systems  in  the  bands  1  164- 
 1  300  MHz,  1  559-  1  610  MHz  and  5  010-  5  030  MHz  under  Nos.  9.12,  9.12A  and  9.13  after  1  January  2005,  without  specifying  direction  (i.  e.,  space-  to-  Earth  or  space-  to-  space). 

 No.  9.11A  applies  the  coordination  provisions  of  Nos.  9.12  to  9.16  where  the  requirement  to  coordinate  is  included  in  a  footnote  to  the  Table  of  Frequency  Allocations  referring  to  No. 
 9.11A.  Since  WRC-  2000,  the  Rules  of  Procedure  (RoP),  issued  by  the  Radio  Regulations  Board  (RRB),  rather  than  the  Radio  Regulations  have  defined  the  services  and  frequency  bands  for 
 which  the  coordination  procedure  under  No.  9.11A  is  required.  The  RRB  considered  the  application  of  No.  9.11A  to  the  bands  given  in  No.  5.329A  (i.  e.,  1  215-  1  300  and  1  559- 
 1  610  MHz  )  and  interpreted  the  Regulations  as  excluding  RNSS  (space-  to-  space)  assignments  in  the  bands  given  in  No.  5.329A  from  any  obligation  to  coordinate  with  other  services  and  with 
 RNSS  (space-  to-  Earth),  but  as  obliging  these  RNSS  (space-  to-  space)  assignments  to  coordinate  with  each  other. 

 In  addition,  many  RNSS  (space-  to-  space)  network  assignments  are  receive-  only  in  the  bands  1215-  1  300  MHz  and  1  559-  1  610  MHz.  Resolution  610  (WRC-  03),  as  referenced  in  No. 
120
 121 
 5.328B,  requires  administrations  to  provide  evidence  of  binding  agreements  for  the  manufacture,  procurement,  and  launch  of  RNSS  systems  and  networks.  This  resolution  was  intended  to  aid 
 bilateral  coordination  between  transmitting  RNSS  systems  and  networks  by  ensuring  such  systems  are  either  in  operation  or  in  the  process  of  being  implemented.  Requiring  Resolution 
 610  (WRC-  03)  data  for  receiving  space  stations  is  unnecessary. 
 Therefore,  modifications  to  No.  5.329A  and  No.  5.328B  are  needed  to  reflect  the  RRB  decision  that  requires  RNSS  (space-  to-  space)  to  coordinate  only  with  other  RNSS  (space-  to-  space)  but  not 
 with  other  services  or  with  RNSS  (space-  to-  Earth),  and  to  remove  Resolution  610  (WRC-  03)  obligations  from  RNSS  receiving  space  stations. 

 Proposal 
 USA/  /1  MOD 
 5.329A  Use  of  systems  in  the  radionavigation-  satellite  service  (space-  to-  space)  operating  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz  is  not  intended  to  provide  safety  service 
 applications,  and  shall  not  impose  any  additional  constraints  on  otherradionavigation-  satellite  service  (space-  to-  Earth)  systems  or  on  other  services  operating  in  accordance  with  the  Table. 

 Reasons:  To  clarify  that  other  systems  in  No.  5.329A  refers  to  the  radionavigation-  satellite  service  (space-  to-  Earth)  and  that  services  refers  to  services  other  than  the  radionavigation-satellite 
 service.

 5.328B  The  use  of  the  bands  1  164-  1  300  MHz,  1  559-  1  610  MHz  and  5  010-  5  030  MHz  by  systems  and  networks  in  the  radionavigation-  satellite  service  for  which  complete  coordination  or 
 notification  information,  as  appropriate,  is  received  by  the  Radiocommunication  Bureau  after  1  January  2005  is  subject  to  the  application  of  the  provisions  of  Nos.  9.12,  9.12A  and  9.13.  As  a 
 consequence  of  No.  5.329A,  for  systems  or  networks  in  the  radionavigation-  satellite  service  (space-  to-  space)  in  the  bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz,  the  application  of  the 
 provisions  of  Nos.  9.12,  9.12A  and  9.13  is  only  with  respect  to  other  systems  or  networks  in  the  radionavigation-  satellite  service  (space-  to-  space).  Resolution  610  (WRC-  03)  shall  also  apply  to 
 transmitting  space  stations. 
 Reasons:  To  make  it  clear  that  the  application  of  the  coordination  procedure  in  Nos.  9.12,  9.12A  and  9.13  is  only  with  respect  to  other  radionavigation-  satellite  service  (space-  to-  space)  in  the 
 bands  1  215-  1  300  MHz  and  1  559-  1  610  MHz  and  to  limit  the  application  of  Resolution  610  (WRC-  03)  to  transmitting  space  stations.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Agenda  Item  1.12:  to  consider  possible  changes  in  response  to  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference:  Advance  publication,  coordination,  notification  and 
 recording  procedures  for  frequency  assignments  pertaining  to  satellite  networks  in  accordance  with  Resolution  86  (WRC-  03); 

 Background  information:  In  response  to  a  request  by  the  scientific  and  research  community  responsible  for  operation  of  active  and  passive  sensors  on  satellites  (as  defined  in  Nos.  1.182  and 
 1.183),  and  in  coordination  with  that  community,  a  set  of  technical  data  relating  to  these  sensors  was  established  for  use  by  all  administrations  for  registration  purposes.  The  Director  of  the 
 Radiocommunication  Bureau  (BR)  published  Circular  Letter  CR/  137  of  14  February  2000,  which  requests  administrations,  when  submitting  advance  publication  information  to  the  Bureau  on 
 planned  Earth  exploration-  satellite  service  (EESS)/  space  research  service  (SRS)  satellite  networks  in  which  active  and/  or  passive  sensors  are  to  be  deployed,  to  kindly  also  submit  specific  information 
 as  attached  to  that  Circular  Letter. 
 Following  CR/  137,  the  Director  of  the  BR  in  his  Report  to  the  World  Radiocommunication  Conference  2003  (WRC-  03)    indicated  that  there  were  additional  data  requirements  for  the 

 EESS/  SRS  contained  in  CR/  137  and  suggested  that  the  conference  might  wish  to  consider  reviewing  Appendix  4  to  include  the  additional  information.  However,  no  proposals  were  submitted 
 to  the  conference. 
 Currently,  the  additional  information  submitted  to  BR  in  accordance  with  Circular  Letter  CR/  137  is  being  scanned  and  published  in  the  International  Frequency  Information  Circular  (IFIC)  (Space 

 services)  as  an  attachment  to  the  Special  Section  related  to  the  relevant  advanced  publication  (API)  only.  It  is  not  reproduced  in  the  IFIC  at  the  time  of  notification.  The  scanned  documents  are  being 
 published  once  on  IFIC  CD-  ROM.  These  data  are  neither  stored  in  the  Space  Network  System  (SNS)  database  nor  published  on  Space  Radiocommunication  Station  on  CD-  ROM.  ****  Therefore, 
 the  information  concerning  EESS  and  SRS  satellite  networks  where  active  and  passive  sensor  systems  are  to  be  deployed  is  not  easily  available  after  publication  of  the  API  on  the  relevant  IFIC. 
 This  information  is  useful  in  analyzing  the  compatibility  of  these  sensors  with  systems  operating  in  other  services  and  facilitates  their  advance  publication,  notification  and  the  subsequent  entry  in  the 
 Master  International  Frequency  Register  (MIFR). 
 To  address  the  need,  the  data  elements  contained  in  Appendix  4  were  reviewed  to  determine  which  existing  elements  should  be  required  to  best  facilitate  the  advance  publication  and  notification  of 

 active  and  passive  sensors  on  satellites.  Based  on  the  review,  the  addition  of  two  new  columns  to  account  for  the  advance  publication  and  notification  of  active  and  passive  sensors  are  proposed. 
 The  inclusion  of  the  new  columns  would  consequentially  require  modifications  to  the  BR  software  and  revisions  to  the  Preface  to  the  IFIC,  inter  alia,  the  inclusion  of  new  station  classes.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 Agenda  Item  1.12:  to  consider  possible  changes  in  response  to  Resolution  86  (Rev.  Marrakesh,  2002)  of  the  Plenipotentiary  Conference:  Advance  publication,  coordination, 
 notification  and  recording  procedures  for  frequency  assignments  pertaining  to  satellite  networks  in  accordance  with  Resolution  86  (WRC-  03); 

 Regulatory  Procedures  and  associated  technical  criteria  applicable  to  satellite  networks 
 Modification  to  Appendix  7,  Table  10 

 Background  information:  Resolution  86  (Rev.  Marrakesh,  2002)  requested  that  WRC-  03  and  subsequent  Conferences  review  the  regulatory  procedures  associated  with  the  advance 
 publication,  coordination,  notification  and  recording  of  frequency  assignments  pertaining  to  satellite  network.  WRC-  03  identified  in  Resolution  86  (WRC-  03)  the  scope  and  the  criteria  to  be 
 used  for  the  implementation  of  Resolution  86  (Rev.  Marrakesh,  2002).  Resolves  1  of  Resolution  86  (WRC-  03)  specifically  states  that  WRC-  07  should  consider  any  proposals  which 
 deal  with  deficiencies  in  the  advance  publication,  coordination,  notification  and  recording  procedures  of  the  Radio  Regulations  (RR)  for  space  services  which  have  either  been  identified 
 by  the  Board  and  included  in  the  Rules  of  Procedure  or  which  have  been  identified  by  administrations  or  by  the  Bureau  as  appropriate. 

 A  review  of  Appendix  7,  Table  10  (Predetermined  coordination  distance)  indicates  that  the  case  of  ground-  based  earth  stations  and  aircraft  terrestrial  stations,  except  for  those  specifically 
 identified  cases  in  the  table,  is  missing.  In  the  past  the  Radiocommunications  Bureau  has  used  the  predetermined  distance  of  500  km  for  this  case,  e.  g.,  see  Document  RRB98/  134(  Rev.  1)  dated 
 8  December  1998.  This  coordination  distance  was  derived  assuming  line-  of-  sight  propagation  between  the  aircraft  and  ground-  based  stations  with  a  4/  3  Earth  radius  and  the  aircraft  altitude  of 
 12  km.  The  500  km  is  consistent  with  the  distance  currently  applicable  to  the  similar  cases  of  coordination  between  aircraft  and  ground-  based  stations  such  as  i)  ground-  based  earth  stations  in 
 the  bands  below  1  GHz  to  which  No.  9.11A  applies/  ground-  based  mobile  in  the  bands  within  the  range  1-  3  GHz  to  which  No.  9.11A  applies  and  aircraft  (mobile)  terrestrial  stations;  ii)  aircraft 
 (mobile)  earth  stations  and  ground-  based  terrestrial  stations;  and  iii)  non-  GSO  MSS  feeder-  link  earth  stations  and  aircraft  (mobile)  terrestrial  stations.  To  cover  the  case  of  ground-  based  earth 
 stations  and  aircraft  terrestrial  stations,  Table  10  needs  to  be  modified  to  include  this  case  with  a  coordination  distance  of  500  km.

 DRAFT  PROPOSALS  FOR  THE  WORK  OF  THE  CONFERENCE 
 Agenda  Item  1.17:  to  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); 

 Background  Information:  WRC-  03  made  a  conditional  secondary  allocation  to  the  fixed-  satellite  service  (FSS)  for  feeder  links  for  non-  geostationary-  satellite  (NGSO)  networks  in  the 
 mobile-  satellite  service  (MSS)  with  service  links  below  1  GHz  (NGSO-  MSS)  through  RR  5.539A  in  the  bands  1  390    1  392  MHz  (Earth-  to-  space)  and  1  430    1  432  MHz  (space-  to-Earth). 
 However,  due  to  the  fact  that  there  were  insufficient  and/  or  incomplete  studies  and  test  measurements  with  regard  to  the  protection  of  other  services  with  allocations  in  these  bands  or  in 
 the  nearby  passive  band  1  400    1  427  MHz,  Resolution  745  (WRC-  03)  resolves  that  these  feederlink  allocations  shall  not  be  used  until  the  completion  of  all  studies  and  the  results  of  these 
 studies  reported  to  WRC-  07. 
 The  frequency  band  1  350    1  400  MHz  is  allocated  worldwide  on  a  primary  basis  to  the  radiolocation  service  (RLS)  and  in  Region  1  to  the  fixed  and  mobile  services.  The  band  1  370   
 1  400  MHz  is  allocated  worldwide  on  a  secondary  basis  to  the  space  research  (SRS)  (passive)  and  Earth  exploration-  satellite  (EESS)  (passive)  services  by  RR  5.339.  The  band  1  330    1  400 
 MHz  is  also  used  by  the  radio  astronomy  service  (RAS)  for  observations  of  the  red-  shifted  neutral  hydrogen  line  and  RR  5.149  urges  administrations  to  take  all  practicable  steps  to  protect 
 it  from  harmful  interference. 
 The  band  1  400-  1  427  MHz  is  allocated  to  the  EESS  (passive),  the  RAS  and  the  SRS  (passive)  on  a  worldwide  basis.  For  the  RAS,  this  band  is  the  most  important  band  for  studies  of  the 
 hydrogen  line  and  for  continuum  observations.  This  band  is  also  used  world-  wide  for  the  Very  Long  Baseline  Interferometry  (VLBI)  technique  which  is  utilized  for  radio  astronomical  studies 
 requiring  high  angular  resolution.  For  the  EESS  (passive),  the  band  1  400    1  427  MHz  is  a  vital  resource  for  measuring  ocean  salinity  and  soil  moisture  content  of  the  Earth.  This  band  is  one  of 
 the  select  bands  for  which  RR  5.340  prohibits  all  emissions,  emphasizing  its  particular  importance  for  the  science  community. 

 The  band  1  427    1  452  MHz  is  allocated  on  a  primary  basis  to  the  fixed  and  mobile  services  worldwide.  The  band  1  427    1  429  MHz  is  also  allocated  on  a  primary  basis  to  the  space 
 operation  service  (Earth-  to-  space)  in  all  three  Regions.  Additionally,  RR  5.342  allocates  the  band  1  429    1  535  MHz  on  a  primary  basis  in  some  administrations  to  the  aeronautical  mobile 
 service  exclusively  for  the  purposes  of  aeronautical  telemetry  within  their  national  territory. 
 A.  Band  1  430    1  432  MHz  (feederlink  downlink) 

 Since  the  NGSO-  MSS  feederlinks  are  allocated  on  a  secondary  basis,  they  cannot  cause  harmful  interference  to  nor  claim  protection  from  the  fixed  and  mobile  services  in  this  band.  ITU-  R 
 studies  based  on  the  fractional  degradation  of  performance  criterion  used  by  the  fixed  service

 To  protect  the  radioastronomy  service  operations  in  the  1  330    1  400  MHz  band,  Recommendation  ITU-  R  M.[  8/  102  Rev.  1]  recommends  that  the  NGSO-  MSS  feederlink  earth 
 stations  be  separated  from  radio  astronomy  stations  which  conduct  observations  in  the  band  1  400    1  427  MHz,  such  that  the  total  data  loss  due  to  feederlink  uplink  and  downlink  emissions 
 does  not  exceed  2%. 
 To  protect  the  EESS  (passive)  operations  in  the  band  1  400    1  427  MHz,  Recommendation  ITU-  R  M.  [8/  101  Rev.  1]  recommends  that  an  unwanted  emission  power  limit  of  63  dBW  in  the 
 passive  band  1  400    1  427  MHz  at  the  antenna  port  of  the  NGSO-  MSS  feederlink  earth  station  would  be  sufficient  to  protect  all  EESS  passive  sensors  which  are  expected  to  use  the  band. 

 One  ITU-  R  study  was  done  on  the  potential  interference  from  NGSO-  MSS  feederlink  uplinks  that  may  operate  in  the  1  390    1  392  MHz  band  into  passive  sensors  operating  in  the  secondary 
 allocation  to  EESS  (passive)  in  the  1  370    1  400  MHz  band.  The  results  of  this  study  indicate  that  the  co-  channel  interference  into  the  passive  sensor  would  exceed  the  interference  threshold 
 by  as  much  as  82  dB  and  as  often  as  42%  of  the  time. 
 Summary 
 From  these  study  results  given  in  Resolution  745  (WRC-  03),  it  is  likely  that  the  NGSO-  MSS  feederlinks  will  be  able  to  use  the  allocated  bands  only  with  significant  constraints  required  to 
 protect  the  existing  services.  It  is  clear  that  some  studies  have  indicated  problems  sharing  the  1  390    1  392  MHz  band  with  existing  services.  Furthermore,  no  service  providers  are 
 continuing  to  pursue  opportunities  or  participating  in  relevant  studies  to  use  this  allocation.  Their  absence  indicates  a  lack  of  need  for  the  allocation.  Therefore,  suppression  of  the 
 conditional  allocation  to  the  NGSO-  MSS  feederlink  allocations  in  the  1  390    1  392  MHz  and  1  430    1  432  MHz  bands  is  proposed. 

 The  absence  of  NGSO-  MSS  interests  indicated  the  lack  of  need  for  the  allocation.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 

 WRC-  07  Agenda  Item  1.20  1  :  to  consider  the  results  of  studies,  and  proposals  for  regulatory  measures,  if  appropriate,  regarding  the  protection  of  the  Earth  exploration-  satellite  service  (passive)  from 
 unwanted  emissions  of  active  services  in  accordance  with  Resolution  738  (WRC  03); 
 Background  Information:  The  resolves  in  Resolution  738  calls  for  three  actions:  1)  study  the  compatibility  between  EESS  (passive)  and  the  corresponding  active  services  listed  in  the  Table  in 
 Resolution  738  to  update  Recommendation  ITU-  R  SM.  1633  or  develop  additional  Recommendations;  2)  further  study  the  impact  of  implementing  the  values  in  considering  f  )  and  g)  in  the  bands  31 
 31.3  GHz  and  51.4  52.6  GHz  for  unwanted  emissions  of  systems  operating  in  Region  2  and  3,  taking  into  account  that  the  impact  on  fixed-  service  systems  in  Region  1  is  documented  in  ITU-  R 
 Recommendation  SM.  1633;  and  3)  review  the  results  of  studies  in  1)  and  2)  in  order  to  consider  regulatory  measures,  if  appropriate,  to  ensure  the  protection  of  the  EESS  (passive)  operating  in  the 
 bands  listed  in  the  table  in  Resolution  738  (WRC  03)  from  unwanted  emissions  of  active  services  operating  in  the  corresponding  bands  while  taking  into  account  the  impact  on  all  concerned  services  of 
 implementing  or  not  implementing  such  measures.  The  table  below  shows  the  frequency  band  and  radiocommunication  service  combinations  within  the  scope  of  the  agenda  item.

 Studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  active  services  in  some  of  these  bands  do  not  produce  significant  unwanted  emissions  in  the  adjacent  passive  band.  However,  active 
 services  in  other  bands  produce  unwanted  emissions  in  excess  of  EESS  (passive)  protection  requirements.  Because  of  the  differences  between  the  active  services,  and  the  differences  in  the  use  of 
 the  active  and  passive  services  from  band  to  band,  the  solutions  for  this  agenda  item  have  been  determined  on  a  band-  by-  band  and  service-  by-  service  basis.  The  proposed  solutions  were  determined 
 considering  the  impact  to  both  the  active  and  passive  services. 
 Resolution  738  can  be  suppressed,  and  there  is  no  need  for  an  agenda  item  dealing  with  unwanted  emission  levels  in  EESS  (passive)  bands  for  the  next  Conference.

 5.  AAA  In  order  to  ensure  the  protection  of  the  Earth  exploration-  satellite  (passive)  service  in  the  band  1  400  1  427  MHz,  the  unwanted  emissions  power  delivered  to  the  antenna  of  any  station  in  the 
 fixed  service  operating  in  the  band  1  350  1  400  MHz  or  in  the  band  1  427  1  452  MHz  shall  be  limited  to  45  dBW  in  the  27  MHz  reference  bandwidth  of  the  band  1  400  1  427  MHz.  Fixed  service  systems 
 in  operation  at  the  date  of  entry  into  force  of  the  Final  Acts  of  WRC-  07  are  not  subject  to  this  limit. 
 Reasons:  Results  of  studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  large  numbers  of  higher  power  fixed  service  transmitters  can  cause  significant  levels  of  unwanted  emissions 
 in  the  1  400  1  427  MHz  passive  band.  Considering  equitable  burden-  sharing  between  the  active  and  passive  services,  the  single-  entry  unwanted  emission  limit  proposed  for  future  systems  will  slightly 
 exceed  the  desired  protection  level  of  the  EESS  (passive)  sensors  in  some  cases,  but  will  still  allow  the  collection  of  valuable  scientific  data  and  will  not  place  an  undue  burden  on  the  future  development  and 
 use  of  the  fixed  service  in  these  nearby  bands. 
 USA/  /3  NOC 
 No  change  to  Radio  Regulations  regarding  the  radiolocation  service  allocation  in  the  band  1  350  1  400  MHz. 

 Reasons:  Although  studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  the  radiolocation  unwanted  emissions  in  the  EESS  (passive)  band  at  1  400  1  427  MHz  would  exceed  the 
 permissible  interference  threshold  in  Recommendation  ITU  R  SA.  1029  2,  any  interference  would  occur  for  only  short  time  periods  and  would  be  readily  discernible  by  users  of  the  remote  sensing  data, 
 allowing  corrupted  data  to  be  discarded.  The  remaining  uncorrupted  data  is  expected  to  satisfy  the  scientific  objectives  of  the  EESS  missions.  Studies  also  show  that  radars  would  experience 
 unacceptable  degradation  in  operational  coverage  and  range,  target  resolution,  and  accuracy  if  required  to  meet  unwanted  emission  limits  in  the  1  400  1  427  MHz  band.  As  with  other  pairs  of  active  and 
 passive  bands,  use  of  portions  of  the  allocated  bands  must  not  be  restricted.  Radars  would  suffer  an  increased  likelihood  of  interference  from  other  radars  and  a  reduction  in  coverage  range,  while  a 
 reduced  bandwidth  would  be  inadequate  for  remote  sensing  requirements.

 No  change  to  Radio  Regulations  regarding  the  fixed-  satellite  service  (Earth-  to-  space)  allocation  in  the  band  30-  31  GHz. 

 Reasons:  Results  of  studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  unwanted  emissions  from  the  FSS  in  the  30-  31  GHz  band  do  not  exceed  the  recommended 
 protection  criteria  for  the  EESS  (passive)  in  the  31.3-  31.5  GHz  band.  The  FSS  allocation  is  separated  from  the  EESS  (passive)  allocation  by  300  MHz,  which  greatly  reduces  the  possibility 
 of  FSS  unwanted  emissions  exceeding  the  protection  criteria  in  the  EESS  (passive)  band.  Unwanted  emission  limits  in  the  EESS  (passive)  band  are  unnecessary,  and  could  constrain  the

 5.  CCC  In  order  to  ensure  the  protection  of  the  Earth  exploration-  satellite  (passive)  service  in  the  band  31.3  31.5  GHz,  the  unwanted  emissions  power  delivered  to  the  antenna  of  any  station

 systems  in  operation  at  the  date  of  entry  into  force  of  the  Final  Acts  of  WRC  07  are  not  subject  to  this  limit. 

 Reasons:  Studies  documented  in  Recommendation  ITU  R  SM.  1633  indicate  that  EESS  (passive)  systems  in  the  31.3  31.5  GHz  band  are  protected  if  unwanted  emissions  in  that  band 
 from  fixed  service  transmitters  in  the  31.0  31.  3  GHz  band  do  not  exceed  38  dBW  in  any  100  MHz  reference  bandwidth.  Measures  to  ensure  that  future  FS  systems  in  the  31.0  31.3  GHz

 service  operating  in  the  band  47.2-  50.2  GHz  in  Regions  2  and  3,  49.44-  50.2  GHz  in  Region  1,  and  50.4-  51.4  GHz  in  all  Regions  shall  be  limited  to  30  dBW  in  the  200  MHz  reference 
 bandwidth  of  the  band  50.2-  50.4  GHz.  Fixed-  satellite  service  systems  in  operation  at  the  date  of  entry  into  force  of  the  Final  Acts  of  WRC-  07  are  not  subject  to  this  limit. 

 Reasons:  Results  of  studies  documented  in  Recommendation  ITU  R  SM.  1633  show  that  fixed-satellite  service  uplink  transmitters  operating  in  bands  adjacent  to  then  50.2-  50.4  GHz  passive 
 band  can  cause  significant  levels  of  unwanted  emissions  in  the  50.2-  50.4  GHz  passive  band.

 5.  EEE  In  order  to  ensure  the  protection  of  the  Earth  exploration-  satellite  (passive)  service  in  the  band  52.6  54.25  GHz,  the  unwanted  emissions  power  delivered  to  the  antenna  of  any  station 
 in  the  fixed  service  operating  in  the  band  51.4  52.6  GHz  shall  be  limited  to  33  dBW  in  any  100  MHz  reference  bandwidth  in  the  band  52.6  54.25  GHz.  Fixed-  service  systems  in  operation  at  the 
 date  of  entry  into  force  of  the  Final  Acts  of  WRC-  07  are  not  subject  to  this  limit. 
 Reasons:  Studies  documented  in  Recommendation  ITU  R  SM.  1633  indicate  that  EESS  (passive)  systems  in  the  52.6  54.25  GHz  band  are  protected  if  unwanted  emissions  in  that  band 
 from  fixed  service  transmitters  in  the  51.4  52.  6  GHz  band  do  not  exceed  33  dBW  in  any  100  MHz  reference  bandwidth.  Measures  to  ensure  that  future  FS  systems  in  the  51.4  52.6  GHz 
 band  do  not  exceed  this  level  will  not  constitute  an  undue  burden  on  the  fixed  service.

 RESOLUTION  738  (WRC-  03) 
 Compatibility  analyses  between  the  Earth  exploration-  satellite  service  (passive)  and  active  services 

 Reasons:  Consequential  to  completion  of  this  agenda  item.  All  of  the  actions  required  under  this  Resolution  will  have  been  completed  at  WRC-  07  and  it  may  be  suppressed.  The  technical 
 studies  will  either  have  confirmed  that  the  unwanted  emissions  do  not  interfere  with  the  EESS  (passive)  or  appropriate  regulatory  measures,  if  necessary,  will  have  been  determined  and 
 decided  by  WRC-  07.
