 THE  FCC'S  ADVISORY  COMMITTEE  FOR  THE  2003  WORLD  RADIOCOMMUNICATION  CONFERENCE  APPROVES 
 DRAFT  PROPOSAL 
 On  October  31,  2002,  the  World  Radiocommunication  Conference  Advisory  Committee  (WRC-  03  Advisory  Committee)  adopted  a  recommendation  to  the  Commission  on  an  issue  that  the  2003  World 
 Radiocommunication  Conference  (WRC-  03)  will  address.  The  WRC-  03  Advisory  Committee  was  established  by  the  Commission  in  January  2001  to  assist  it  in  the  development  of  proposals  for  WRC-  03. 
 To  that  end,  the  WRC-  03  Advisory  Committee  has  forwarded  the  recommendations  it  has  developed  since  the  beginning  of  2001  to  the  Commission  for  consideration.  We  have  attached  to  this  Public  Notice 
 the  WRC-  03  Advisory  Committees  recommendation,  which  is  in  the  form  of  a  recommended  draft  proposal  to  the  WRC-  03.  We  appreciate  the  substantial  amount  of  work  that  the  WRC-  03  Advisory 
 Committee  has  put  into  developing  its  recommendation.  This  Public  Notice  requests  comments  on  this  recommendation. 


 Based  upon  our  initial  review  of  the  recommendation  forwarded  to  the  Commission,  the  International  Bureau,  in  coordination  with  other  Commission  Bureaus  and  Offices,  tentatively  concludes  that  we  can 
 generally  support  the  proposal  recommended  by  the  WRC-  03  Advisory  Committee.  We  seek  comment  on  the  recommendation  that  appears  in  the  WRC-  03  Advisory  Committee  document  and  on  our  tentative 
 conclusion. 
 In  addition,  the  National  Telecommunications  and  Information  Administration  (NTIA)  has  submitted  letters  to  the  Commission  containing  draft  proposals  that  have  been  developed  by  the  Executive  Branch 


 Agencies.  We  also  request  comment  on  these  draft  proposals,  which  are  attached  hereto  as  well. 
 The  FCC  will  consider  the  draft  proposals  and  comments  provided  in  its  upcoming  consultations  with  the  U.  S.  Department  of  State  and  NTIA  in  the  development  of  U.  S.  proposals  to  WRC-  03.  Once  agreed  by 


 these  agencies  of  the  U.  S.  Government,  proposals  will  be  used  by  U.  S.  delegations  at  bilateral,  regional  and  international  meetings.  The  draft  proposals  attached  to  this  Public  Notice  may  evolve  as  we  approach 
 WRC-  03  and  during  the  course  of  interagency  discussions.  Therefore,  they  do  not  constitute  the  final  national  position  on  these  issues. 


 The  complete  texts  of  these  draft  proposals  are  also  available  in  the  FCC's  Reference  Information  Center,  Room  CY-  A257,  445  12th  Street,  SW,  Washington,  DC  20554  and  by  accessing  the  FCC's  WRC-  03 
 world  wide  web  site  at  http://  www.  fcc.  gov/  wrc-  03.  To  comment  on  the  proposals,  please  submit  an  original  and  one  copy  of  your  comments  to  the  Office  of  the  Secretary,  Federal  Communications 
 Commission,  445  12th  Street,  SW,  Washington,  DC  20554  and  provide  a  courtesy  copy  to  Alex  Roytblat,  FCC  WRC-  03  Director,  Room  6-  A738.  When  possible,  these  comments  should  also  be  forwarded  to  the 
 Commission  via  the  Internet  at:  wrc03@  fcc.  gov.  Comments  should  refer  to  specific  proposals  by  document  number.  The  deadline  for  comments  on  the  draft  proposals  and  NTIA  letters  is  December  2, 
 2002.

 Doc.  WAC/  163(  31.10.02) 


 Resolution  228 
 WRC-  03  Agenda  Item  1.22:  To  consider  progress  of  ITU-  R  studies  concerning  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000,  in  accordance  with  Resolution  228 


 (WRC-  2000). 
 Background: 
 Resolution  228  (WRC-  2000),  which  is  related  to  Agenda  Item  1.22,  invites  ITU-  R  to  continue  studies  on  overall  objectives,  applications  and  technical  and  operational  implementation  for  the 
 future  development  of  IMT-  2000  and  systems  beyond.  ITU-  R  Working  Party  8F  has  developed  a  Draft  New  Recommendation  on  the  vision,  framework  and  overall  objectives  of  the  future 
 development  of  IMT-  2000  and  systems  beyond  IMT-  2000  [DNR-  VIS],  which  is  expected  to  be  approved  at  the  ITU-  R  Study  Group  8  meeting  in  February  2003.  Studies  will  continue  to  be 
 carried  out  in  WP  8F,  and  are  scheduled  to  be  completed  before  WRC-  07.  The  results  of  these  studies  will  indicate  which  requirements  should  be  reviewed  by  WRC-  07.

 db)  c)  that  the  technical  characteristics  of  IMT-  2000  are  specified  in  ITU-  R  and  ITU-  T  Recommendations,  including  Recommendation  ITU-  R  M.  1457  which  contains  the  detailed 
 specifications  of  the  radio  interfaces  of  IMT-  2000;  c)  that  Question  ITU-  R  229/  8  addresses  the  future  development  of  IMT-  2000  and  systems 
 beyond  IMT-  2000;  d)  that  the  ITU-  R  has  adopted  [Draft  New]  Recommendation  ITU-  R  M.[  DNR-  VIS],  which 
 addresses  the  vision,  framework,  and  overall  objectives  of  the  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000; 
 e)  that  [Draft  New]  Recommendation  ITU-  R  M.[  DNR-  VIS]  has  identified  the  new  elements  of  systems  beyond  IMT-  2000  that  are  to  be  developed,  and  has  stated  that  such  systems  will  closely 
 inter-  work  with  the  currently  operating  IMT-  2000  and  with  future  developments  of  IMT-  2000;  f)  that  the  technical  characteristics  of  systems  beyond  IMT-  2000  have  not  been  specified  in  an 
 ITU-  R  Recommendation,  but  remain  under  study  within  the  ITU-  R;  eg)  that  it  was  nineeight  years  ahead  of  the  IMT-  2000  initial  deployment  that  WARC-  92 
 identified  the  spectrum  for  IMT-  2000  in  No.  5.388  and  under  the  provisions  of  Resolution  212  (Rev.  WARC-  927); 
 f)  that  the  review  of  IMT-  2000  spectrum  requirements  at  WRC-  2000  concentrated  on  the  bands  below  3  GHz; 
 gh)  that  telecommunication  and  information  technologies  evolve  rapidly;  ei)  that,  as  it  is  with  many  other  services  and  systems,  adequate  spectrum  availability  is  a 
 prerequisite  for  the  technological  and  economic  success  of  the  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000; 
 jj)  f)  that  the  demand  for  the  provision  of  multimedia  applications  such  as  high-  speed  data,  IP-  packet  and  video  by  mobile  communication  systems  will  continue  to  increase; 
3
 4 
 kk)  g)  that  the  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000  is  foreseen  to  address  the  need  for  higher  data  rates  than  those  of  currently  deployedplanned  for  IMT-  2000 
 systems;  ll)  h)  that,  for  global  operation  and  economy  of  scale,  it  is  desirable  to  agree  on  common 
 technical,  operational  and  spectrum-  related  parameters  of  systems,;  mm)  i)  that  it  is  therefore  timely  to  study  technical,  spectrum  and  regulatory  issues  pertinent  to  the 
 future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000,;  nn)  that  Question  ITU-  R  77-  4/  8  addresses  adaptation  of  mobile  radiocommunications 
 technology  to  the  needs  of  developing  countries,  including  the  optimum  arrangements  and  technical  characteristics  needed  to  use  mobile  technology/  equipment  in  urban,  rural  or  remote  areas; 
 o)  that  all  existing  services,  some  of  which  are  also  evolving  to  permit  the  use  of  higher  data  rates  and  throughput  within  their  allocations  in  order  to  meet  increasing  user  demands  and 
 requirements,  should  be  taken  into  account  in  any  studies  evaluating  potential  spectrum  for  systems  beyond  IMT-  2000, 


 noting  a)  that  the  IMT-  2000  radio  interfaces  as  defined  in  Recommendation  ITU-  R  M.  1457  are 
 expected  to  evolve  within  the  framework  of  the  ITU-  R  beyond  those  initially  specified,  to  provide  enhanced  services  and  services  beyond  those  envisaged  in  the  initial  implementation; 
 b)  that  the  use  of  the  spectrum  identified  for  IMT-  2000  does  not  preclude  the  use  of  these  bands  by  any  station  in  the  services  to  which  they  are  allocated  and  does  not  establish  priority  in  the 
 Radio  Regulations,  b)  that  the  ITU-  R  has  identified  the  new  elements  of  systems  beyond  IMT-  2000  to  be 
 developed,  which  will  closely  inter-  work  with  the  currently  operating  IMT-  2000  and  the  enhanced  IMT-  2000, 


 recognizing  a)  the  time  necessary  to  develop  and  agree  on  the  technical,  operational,  spectrum  and 
 regulatory  issues  associated  with  the  continuing  enhancement  of  mobile  services;  b)  that  service  functionalities  in  fixed  and  mobile  networks  are  increasingly  converging; 
 c)  that  future  mobile  systems  will  require  the  adoption  ofemploy  more  spectrum-  efficient  techniques  than  those  used  by  current  mobile  systems; 
 d)  the  needs  of  developing  countries  for  the  cost-  effective  and  rapid  implementation  of  advanced  mobile  communication  technologies  and  the  propagation  characteristics  of  lower 
 frequency  bands  that  result  in  larger  cell  sizes.,;  e)  that  the  review  of  IMT-  2000  spectrum  requirements  at  WRC-  2000  concentrated  on  the 
 bands  below  3  GHz  and  that  these  bands  remain  technically  desirable  for  both  IMT-  2000  and  systems  beyond  IMT-  2000; 
 f)  that,  to  the  extent  that  they  may  not  be  the  same,  it  would  be  preferable  for  the  location  in  the  radiofrequency  spectrum  of  bands  that  support  systems  beyond  IMT-  2000  to  be  reasonably 
 close  to  the  location  of  bands  already  identified  for  IMT-  2000  and  predecessor  services,  g)  that  many  countries  have  not  yet  made  available  spectrum  already  identified  for  IMT-  2000, 
 due  to  various  reasons,  including  the  use  of  these  bands  by  existing  services;  h)  that  studies  may  show  that  the  identification  of  certain  bands  for  use  by  the  future 
 development  of  IMT-  2000  and  systems  beyond  IMT-  2000  may  be  precluded  by  the  use  of  these  bands  by  existing  services,

 1  to  invite  ITU-  R  to  further  study,  and  develop  Recommendations  on,  continue  studies  on  overall  objectives,  applications  and  technical  and  operational  issues  relating  toimplementation,  as 
 necessary,  for  the  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000; 
 2  to  invite  ITU-  R  to  complete  studies,  in  time  for  WRC-  05/  0607,  on  study  the  spectrum  requirements  and  potential  frequency  ranges  suitable  for  the  future  development  of  IMT-  2000  and 
 systems  beyond  IMT-  2000,  taking  into  consideration  the  bands  currently  identified  for  IMT-  2000  and  the  evolution  of  IMT-  2000  and  pre-  IMT-  2000  systems  therein  through  advances  in 
 technologyand  in  what  time-  frame  such  spectrum  would  be  needed; 
 3  that,  taking  into  account  the  recognizings  above,  the  studies  in  resolves  1  and  2:  a)  examine  the  compatibility  of  the  future  development  of  IMT-  2000  and  systems 
 beyond  IMT-  2000  with  existing  services,  including  their  future  development;  b)  indicate  the  extent  to  which  the  existing  services  and  their  future  development  would 
 be  affected  and  how  they  can  be  protected  from  interference  from  the  future  development  of  IMT-  2000  and  systems  beyond  IMT-  2000,

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  156(  31.10.02) 


 Agenda  Item  1.10.1:  to  consider  the  results  of  studies,  and  take  necessary  actions,  relating  to  exhaustion  of  the  maritime  mobile  service  identity  numbering  resource  (Resolution  344  (WRC-  97)); 


 Background  Information:  This  agenda  item  addresses  the  potential  of  an  impending  exhaustion  of  the  Maritime  Mobile  Service  Identities  (MMSI)  numbering  resource.  Resolution  344  instructs  the 
 Radiocommunication  Bureau  to  monitor  the  status  of  the  MMSI  resource  and  report  the  status  to  each  WRC. 


 A  second  issue  that  can  affect  the  MMSI  numbering  resource  is  potential  assignment  to  aircraft  stations.  Aircraft  used  for  SAR  purposes  may  have  a  need  to  establish  aircraft-  to-  ship  communications 
 using  DSC-  equipped  radios  or  using  universal  shipborne  automatic  identification  systems  (AIS).  This  AIS  communications  requirement  is  addressed  in  ITU-  R  M  1371-  1,  which  includes  a  message  to  be 
 used  for  SAR  aircraft  position  report  and  requires  the  use  of  an  MMSI. 
 Proposal:

 administration  shall  assign  the  identity  to  the  station  in  accordance  with  the  provisions  described  in  Nos.  19.100  to  19.126;  in  so  doing,  it  should  take  into  account  the  relevant  ITU-  R  and  ITU-  T 
 Recommendations.  In  accordance  with  No.  20.16,  administrations  shall  notify  the  Bureau  immediately  when  assigning  maritime  mobile  service  identities

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  160(  31.10.02) 


 Agenda  Item  1.15c:  to  review  the  results  of  studies  concerning  the  radionavigation-  satellite  service  in  accordance  with  Resolutions  604  (WRC-  2000),  605  (WRC-  2000)  and  606  (WRC-  2000); 


 Background  Information:  WRC-  2000  introduced  a  primary  allocation  in  the  5  010-  5  030  MHz  band  to  the  radionavigation-  satellite  service  (RNSS)  (space-  to-  Earth)  (space-  to-  space),  with  a  provisional 
 aggregate  pfd  limit  of  -171  dB(  W/  m  2  )  in  the  4  990-  5  000  MHz  band  at  any  radio  astronomy  observatory  site,  not  to  be  exceeded  for  more  than  2%  of  time,  to  protect  from  harmful  interference 
 radio  astronomy  stations  operating  in  this  band.  In  order  not  to  cause  harmful  interference  to  the  microwave  landing  system  operating  above  5  030  MHz,  the  aggregate  pfd  limit  of  space  stations 
 operating  in  the  radionavigation-  satellite  service  in  the  5  030  -  5  150  MHz  band  was  also  limited  to  -124.5  dB(  W/  m  2  ),  in  any  150  kHz  band  (RR  5.443B). 


 Resolution  604  (WRC-  2000),  dealing  with  compatibility  between  the  radio  astronomy  service  (RAS)  and  the  RNSS  at  5  GHz,  invited  the  ITU-  R  to  conduct,  in  time  for  consideration  by  WRC-  03,  the 
 appropriate  technical,  operational  and  regulatory  studies  to  review  the  provisional  pfd  limit  in  the  4  990-  5  000  MHz  band  concerning  the  operation  of  space  stations,  including  the  development  of  a 
 methodology  for  calculating  the  aggregate  power  levels  in  order  to  ensure  that  the  RNSS  (space-  to-Earth)  in  the  band  5  010-  5  030  MHz  will  not  cause  interference  detrimental  to  the  RAS  in  the  band 
 4  990-  5  000  MHz.  Based  on  the  results  of  the  studies,  Res.  604  (WRC-  2000)  invited  WRC-  03  to  review  the  provisional  pfd  limit  on  the  RNSS  in  the  band  4  990-  5  000  MHz  for  out-  of-  band  space-  to-Earth 
 emissions  of  the  RNSS  operating  in  the  band  5  010-  5  030  MHz.  The  provisions  of  Resolution  604  (WRC-  2000)  currently  apply  to  the  band. 


 Studies  conducted  within  the  ITU-  R  confirmed  the  adequacy  of  the  provisional  aggregate  pfd  limit  to  protect  radio  astronomy  stations  in  the  4  990  -  5  000  MHz  band  from  unwanted  emissions  of  GSO 
 RNSS  satellites  that  might  operate  in  the  5  010  -  5  030  MHz  band.  For  NGSO  RNSS  systems,  a  methodology  to  calculate  the  detrimental  interference  threshold  adequate  to  protect  radio  astronomy 
 sites  was  developed  within  the  ITU-  R,  and  it  is  contained  in  DNR  ITU-  R  M.[  Non-  GSO/  RA].  The  proposal  includes  some  consequential  changes  in  Appendix  4,  annexes  2A  and  2B,  as  well  as  the 
 deletion  of  the  parameter  C.  13  "Class  of  observations"  that  is  no  longer  useful. 
 Proposal: 
 USA/  /  1  MOD 
 5.443B  Additional  allocation:  The  band  5  010-  5  030  MHz  is  also  allocated  to  the  radionavigation-  satellite  service  (space-  to-  Earth)  (space-  to-  space)  on  a  primary  basis.  In  order  not  to 
 cause  harmful  interference  to  the  microwave  landing  system  operating  above  5  030  MHz,  the  aggregate  power  flux-  density  produced  at  the  Earth's  surface  in  the  band  5  030-  5  150  MHz  by  all  the 
 space  stations  within  any  radionavigation-  satellite  service  system  (space-  to-  Earth)  operating  in  the  band  5  010-  5  030  MHz  shall  not  exceed  124.5  dB(  W/  m  2  )  in  a  150  kHz  band.  In  order  to  protect  not  to 
 cause  harmful  interference  to  the  radio  astronomy  service  in  the  band  4  990-  5  000  MHz,  the  aggregate  power  flux  density  produced  in  the  4  990-  5  000  MHz  band  by  all  space  stations  within  any  GSO

 e  d)  that  protection  requirements  for  RAS  are  explained  and  interference  threshold  values  detailed  in  the  Annex  to  Recommendation  ITU-  R  RA.  769-  1; 
 f  e)  that  different  coupling  mechanisms  apply  to  interfering  emissions  from  terrestrial  transmitters  or  from  transmitters  on  board  GSO  or  non-  GSO  satellites; 
 g)  that  this  conference  has  revised  Recommendation  66,  which  calls  for  study  of  those  frequency  bands  and  instances  where,  for  technical  or  operational  reasons,  out-  of-  band  emission  limits  may  be 
 required  in  order  to  protect  safety  services  and  passive  services  such  as  radio  astronomy,  and  the  impact  on  all  concerned  services  of  implementing  or  not  implementing  such  limits;

 the  same  band  4  990-  5  000  MHz  for  out-  of-  band  space-  to-  Earth  emissions  of  RNSS  systems  operating  in  the  band  5  010-  5  030  MHz; 


 b)  that  the  general  problem  of  protection  of  radio  astronomy  and  passive  services  is  under  study  in  ITU-  R,  inter  alia  in  response  to  Recommendation  66, 
 resolves 
 1.  to  invite  WRC-  03  to  review  the  provisional  pfd  limit  on  the  RNSS  in  the  band  4  990-  5  000  MHz  for  out-  of-  band  space-  to-  Earth  emissions  of  the  RNSS  operating  in  the  band  5  010-  5  030  MHz; 


 21  that  the  limits  indicated  in  No.  5.443B  shall  be  applied  provisionally  for  RNSS  systems  operating  in  the  5  010  -  5  030  MHz  band  for  which  complete  notification  information  has  been 
 received  by  the  Bureau  after  2  June  2000; 
 2  that,  for  non-  GSO  RNSS  systems,  the  methodology  and  parameters  specified  in  Recommendation  ITU-  R  M.[  non-  GSO/  RAS]  shall  be  used  for  the  calculation  of  the  aggregate  epfd 
 levels  at  the  sites  of  radio  astronomy  stations 
 3  that,  as  of  3  June  2000,  when  notifying  frequency  assignments  to  a  satellite  network  in  the  radionavigation-  satellite  service  in  the  bands  5  010-  5  030  MHz,  the  responsible  administration  shall 
 provide  the  calculated  values  of  the  aggregate  power  flux-  density  in  the  bands  above  5  030  MHz  and  in  the  band  4  990-  5  000  MHz,  as  defined  in  No.  5.443B,  in  addition  to  the  relevant  characteristics 
 listed  in  Appendix  4. 
 urges  administrations 
 1  to  participate  actively  in  the  aforementioned  studies  by  submitting  contributions  to  ITU-  R; 
10
 11 
 2  to  ensure  that,  to  the  extent  feasible,  systems  designed  to  operate  in  the  RNSS  frequency  band  5  010-  5  030  MHz  incorporate  interference  avoidance  techniques,  such  as  filtering, 
 instructs  the  Radiocommunication  Bureau 
 as  of  the  end  of  WRC-  03,  to  review  and,  if  appropriate,  revise  any  finding  previously  made  in  respect  of  the  compliance  with  the  out-  of-  band  emission  limits  contained  in  No.  5.443B  of  an  RNSS  (space-  to-Earth) 
 system  for  which  notification  information  has  been  received  before  the  end  of  WRC-  03;  in  accordance  with  resolves  1  and  2  above.  this  review  shall  be  based  on  the  values,  as  revised,  if 
 appropriate,  by  WRC-  03. 
 Reasons:  The  modified  footnote  5.443B  allows  for  compatible  operation  of  the  RNSS  in  the  5  010-  5  030  MHz  band  and  the  RAS  in  the  4  990-  5  000  MHz  band.  The  modified  Resolution  604  (WRC-2003) 
 provides  guidance  to  Administrations  for  the  appropriate  methodology  to  be  used  in  computing  the  epfd  levels  of  non-  GSO  RNSS  systems,  and  instructs  the  Bureau  to  check  that  RNSS  systems 
 advance  published  between  the  end  of  WRC-  2000  and  WRC-  03  are  in  conformance  with  the  pfd  and  epfd  levels  in  5.443B.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  155(  31.10.02) 


 Agenda  Item  1.38:  to  consider  provision  of  up  to  6  MHz  of  frequency  spectrum  to  the  Earth  exploration-  satellite  service  (active)  in  the  frequency  band  420-  470  MHz,  in  accordance  with 
 Resolution  727  (Rev.  WRC-  2000); 
 Background  Information:  A  similar  agenda  item  was  debated  at  WRC-  97  resulting  in  a  decision  not  to  adopt  proposed  allocations  for  the  Earth  exploration-  satellite  service  in  the  420-  470  MHz  band.  The 
 Earth  sensing  community  has  identified  that  the  need  for  such  an  allocation,  at  a  radio  spectrum  wavelength  of  approximately  one  meter,  is  important  because  experiments  have  shown  good 
 correlation  of  backscatter  radiation  with  biomass  and  soil  moisture,  which  are  parameters  needed  for  forest  monitoring.  The  need  for  such  forest  monitoring  was  emphasized  at  the  United  Nations 
 Conference  on  Economic  Development  (UNCED)  (Buenos  Aires  -  1992).  Subsequent  to  UNCED  1992,  studies  have  identified  a  minimum  bandwidth  requirement  of  6  MHz  to  satisfy  mission 
 objectives. 
 The  bands  420-  430  and  440-  450  MHz  are  allocated  to  the  radiolocation  service  on  a  primary  basis  in  several  countries,  the  band  430-  440  MHz  is  allocated  to  the  radiolocation  service  on  a  primary  basis 
 worldwide  and  are  used  for  telemetry,  telecommand  and  long-  range  surveillance  by  land,  ship  and  airborne  stations  for  early  missile  warning,  detection  of  low-  observable  targets,  and  the  tracking  of  all 
 objects  in  Earth  orbit.  Studies  to  date  have  shown  the  potential  for  interference  between  EESS  (active)  sensors  and  ground-  based  radars  when  in  the  line  of  sight  of  the  ground-  based  radars.  Preliminary 
 studies  have  also  shown  that  there  is  a  potential  for  interference  from  EESS  (active)  to  airborne  radars  operating  worldwide. 


 The  amateur  community  is  concerned  with  the  possibility  of  harmful  interference  to  amateur  operations  in  the  430-  440  MHz  portion  of  the  band.  There  are  currently  16  amateur  satellites  in  orbit 
 that  use  frequencies  within  the  band  435-  438  MHz  for  both  up  and  down  links  internationally.  The  band  430    440  MHz  is  allocated  to  the  amateur  service  on  a  co-  primary  basis  in  Region  1,  and  on  a 
 primary  basis  in  eight  Region  2  countries:  Argentina,  Colombia,  Costa  Rica,  Cuba,  Guyana,  Honduras,  Panama  and  Venezuela  (No.  5.278).  Elsewhere  in  Region  2  and  in  Region  3,  the  amateur  service 
 allocation  is  secondary.  Additionally,  the  bands  420    430  MHz  and  440    450  MHz  are  allocated  to  the  amateur  service  on  a  secondary  basis  in  Australia,  the  United  States,  Jamaica  and  the  Philippines 
 (No.  5.270).  Studies  to  date  have  shown  the  potential  for  interference  between  EESS  (active)  sensors,  and  amateur  stations  when  the  SAR  is  in  the  line  of  sight  of  amateur  stations,  and  specifically  in  the 
 band  435-  438  MHz,  which  would  be  the  worst-  case  scenario  for  the  amateurs.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  160(  31.10.02) 


 Agenda  Item  7.2:  to  recommend  to  the  Council  items  for  inclusion  in  the  agenda  for  the  next  WRC,  and  to  give  its  views  on  the  preliminary  agenda  for  the  subsequent  conference  and  on  possible  agenda 
 items  for  future  conferences,  taking  into  account  Resolution  801  (WRC-  2000); 
 Background  Information:  WRC-  03  is  competent  to  make  all  the  decisions  that  are  necessary  for  allocations  within  the  4  -10  MHz  spectral  region  through  its  agenda  items  1.23  and  1.36  and,  as  noted 
 above.  All  the  data  and  analysis  have  been  done,  and  will  be  thoroughly  documented  in  the  final  CPM  report.  A  proposal  to  eliminate  the  preliminary  agenda  item  2.5  from  the  final  WRC-  06  agenda  will 
 help  to  support  the  general  feeling  that  something  should  be  done  to  minimize  unnecessary  workloads  at  WRCs.  Furthermore,  WRC-  92  reallocated  200  kHz  in  the  4-  10  MHz  range  to  the  broadcast  service 
 from  the  fixed  service.  This  reallocation  will  take  affect  after  1  April  2007.  Any  further  consideration  of  reallocation  in  the  2006  time  frame  for  the  broadcast  service  will  necessarily  take  into  account  the 
 need  for  reaccomodation  to  the  fixed  service  users  as  a  result  of  WRC-  92,  and  will  most  likely  be  viewed  unfavorably.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  157(  31.10.02) 
 NTIA  revised  the  background  section  of  this  proposal  that  originally  appeared  in  Doc.  WAC/  138(  05.  09.02) 


 Proposal  for  Resolution  801,  Agenda  Item  3.1 


 Agenda  Item  7.2:  to  recommend  to  the  Council  items  for  inclusion  in  the  agenda  for  the  next  WRC,  and  to  give  its  views  on  the  preliminary  agenda  for  the  subsequent  conference  and  on  possible  agenda 
 items  for  future  conferences,  taking  into  account  Resolution  801  (WRC-  2000); 


 Background  Information:  Working  Party  8B  considered  several  studies  on  the  feasibility  of  sharing  between  the  mobile  service  (IMT-  2000)  and  radar  systems  operated  in  the  band  2  700-  2  900  MHz. 
 Those  studies  indicate  sharing  of  the  band  2  700-  2  900  MHz  between  the  mobile  service,  IMT-  2000  and  aeronautical  radionavigation  and  meteorological  radars  is  not  feasible.  Working  Party  8B 
 proposed  that  the  draft  CPM  text  for  Chapter  7,  Future  Work  Program,  reflects,  WRC-  03  may  wish  to  consider  deletion  of  this  agenda  item  from  the  WRC-  05/  06  agenda  (8B/  TEMP/  103-  E,  6  May  2002). 


 The  band  2  700-  2  900  MHz  is  used  worldwide  to  support  airport  surveillance  radars  in  the  aeronautical  radionavigation  service,  which  is  a  safety  service  and  requires  special  measures  to  ensure  their 
 freedom  from  harmful  interference  in  accordance  with  Article  4.10  of  the  Radio  Regulations. 
 Footnote  5.423  allows  meteorological  radars  to  operate  in  the  band  with  equality  to  the  ARNS.  The  primary  weather  meteorological  radar  system  used  for  flight  planning  activities  operates  in  the  band 
 2  700-  2  900  MHz  and  is  often  collocated  at  airports  worldwide,  to  provide  accurate  weather  conditions  for  aircraft.  Also,  these  radars  are  used  to  detect  the  formation  and  movement  observe  the  presence  and 
 calculate  the  speed  and  direction  of  motion  of  severe  weather  elements  such  as  tornadoes,  and  violent  thunderstorms  and  wind  shear.  These  radars  provide  quantitative  area  precipitation  measurements 
 important  to  hydrologic  forecasting  of  potential  flooding.  The  severe  weather  and  motion  detection  capabilities  offered  by  weather  radars  contribute  towards  an  increase  in  the  accuracy  and  timeliness  of 
 warning  services  critical  to  the  protection  of  life  and  property. 


 Proposal: 
 USA/  /  1  SUP 
 3.1  to  consider  results  of  ITU-  R  studies  on  the  feasibility  of  sharing  in  the  band  2  700-  2  900  MHz  between  the  aeronautical  radionavigation  service,  meteorological  radars  and  the  mobile  service,  and  to 
 take  appropriate  action  on  this  subject. 
 Reasons:  WP8B  has  already  determined  that  sharing  is  not  feasible  in  this  band;  therefore  it  is  not  necessary  to  continue  this  agenda  item.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  159(  31.10.02) 


 Agenda  Item  7.2:  to  recommend  to  the  Council  items  for  inclusion  in  the  agenda  for  the  next  WRC,  and  to  give  its  views  on  the  preliminary  agenda  for  the  subsequent  conference  and  on  possible  agenda 
 items  for  future  conferences,  taking  into  account  Resolution  801  (WRC-  2000); 
 Background  Information:  The  frequency  band  5  000-  5  250  MHz  is  allocated  internationally  to  the  aeronautical  radionavigation  service  (ARNS)  on  a  primary  basis.  The  fixed-  satellite  service  (FSS) 
 (Earth-  to-  space)  is  allocated  on  a  primary  basis  in  the  band  5  150-  5  250  MHz  for  the  use  of  feeder  links  for  non-  geostationary  satellite  systems  of  the  mobile-  satellite  service  (5.447A),  as  well  as  in  band 
 5  091-  5  150  MHz  pursuant  to  5.444A.  The  aviation  community  is  exploring  new  applications  in  the  band  5  091-  5  150  MHz. 


 Allocation  for  new  civil  aviation  systems: 
 Two  current  aviation  safety  objectives  are  to  provide  more  information  to  the  pilot/  cockpit,  and  to  reduce  runway  incursions.  In  the  bands  5  091-  5  150  MHz,  a  new  system  called  the  airport  network 


 and  location  equipment  (ANLE)  would  address  both  of  these  objectives.  In  its  most  basic  form,  ANLE  is  a  high  integrity  grid  of  multilateration  sensors,  integrated  with  a  wireless  network  that  would  provide 
 aeronautical  radionavigation  and  safety  communications  for  the  airport  area  and  would  provide  the  cockpit  with  access  to  appropriate  information  via  a  high-  bandwidth  connection.  Those  same 
 transmissions  would  be  used  to  derive  three-  dimensional  position  of  the  mobile  user.  This  derived  position  that  could  then  be  broadcast  via  the  ANLE  data  link  to  provide  all  users  with  situational 
 awareness  on  the  airport  surface.  Adding  simple  transmitters  to  other  surface-  movement  vehicles  would  allow  for  the  development  of  a  high-  fidelity  complete  picture  of  the  airport  surface 
 environment.  A  new  provision  in  this  band  would  accommodate  the  systems  such  as  ANLE.  The  International  Air  Transport  Association  (IATA)  is  considering  a  similar  system  called  Airport  Vehicle 
 Position  System  (AVPS),  which  would  also  operate  in  the  band  5  091-  5  150  MHz.  The  AVPS  is  intended  to  monitor  surface  movement,  reduce  runway  incursion  and  increase  airport  security. 


 New  aeronautical-  fixed  service: 
 Currently  there  is  no  aeronautical  band  to  support  applications  that  transmit  critical  aeronautical  data  from  systems  such  as  wind  shear  radars,  remote  maintenance  monitoring  systems,  runway  lighting, 


 low-  level  wind  shear  alert  systems,  automated  weather  surface  observing  systems,  or  automatic  weather  observation  systems.  Data  from  these  systems  are  transmitted  in  other  bands  that  are  allocated 
 to  the  fixed  and  mobile  services,  which  are  also  used  by  others  for  non-  aviation  uses.  Redundant  paths  are  used  to  ensure  integrity  and  reliability  requirements  are  met.  In  most  cases,  this  data  is  flight 
 critical,  thus  the  applications  should  be  accommodated  in  an  appropriate  aeronautical  allocation.  The  increasing  trend  of  flight  operations  will  result  in  shortage  of  assignments  in  these  bands  and  little 
 protection  from  other  services.  An  allocation  for  the  aeronautical  fixed  service  in  the  band  5  091-  5  150  MHz  would  help  alleviate  the  spectrum  congestion  problem.  It  is  impractical  from  a  cost  and  loss-  of-facility- 
 use  standpoint  to  run  wires  to  transmit  the  information  --  especially  on  established  airports.  The  fixed  links  would  operate  compatibly  with  the  ANLE  and  AVPS  applications  also  planned  for  this 
 band.

 RESOLUTION  801  (WRC-  2003) 
 Aagenda  for  the  2005/  2006  World  Radiocommunication  Conference 


 The  World  Radiocommunication  Conference  (Istanbul,  2000),  (Geneva,  2003), 
 Reasons:  Editorial 
 resolves  to  give  the  view 


 USA/  /2  ADD 
 2.  xx  to  consider  a  new  worldwide  primary  allocation  to  accommodate  a  system  that  would  provide  supplemental  radionavigation  data  in  the  band  5  091-  5  150  MHz; 


 Reasons:  New  provisions  in  the  ITU  Radio  Regulations  in  the  band  5  091-  5  150  MHz  for  supplemental  aeronautical  radionavigation  data  would  accommodate  systems  such  as  the  (Airport 
 Network  and  Location  Equipment)  ANLE  and  Airport  Vehicle  Position  System  (AVPS)  that  would  aid  in  providing  more  information  to  the  pilot/  cockpit  and  reduce  the  risk  of  runway  incursions.  ANLE 
 would  provide  aeronautical  radionavigation  and  safety  communications  for  the  airport  area.  The  AVPS  is  intended  reduce  runway  incursion  and  increase  airport  security.  The  AVPS  would  operate  in 
 the  aeronautical  radionavigation  service.

 2.  xx  to  consider  a  new  worldwide  primary  allocation  to  accommodate  the  aeronautical  fixed  service  links  in  the  band  5  091-  5  150  MHz; 


 Reasons:  The  new  allocation  of  the  aeronautical  fixed  service  in  the  band  5  091-  5  150  MHz  would  allow  critical  aeronautical  data  to  be  transmitted  between  aeronautical  facilities  in  59  MHz  of 
 contiguous  spectrum  for  aeronautical  use.  Aeronautical  fixed  applications  would  transmit  critical  aeronautical  data  from  systems  such  as  wind  shear  radars,  remote  maintenance  monitoring  systems, 
 runway  lighting,  low-  level  wind  shear  alert  systems,  automated  weather  surface  observing  systems,  or  automatic  weather  observation  systems.  The  new  service  would  also  alleviate  some  of  the  spectrum 
 congestion  in  other  bands.

 DRAFT  PROPOSAL  FOR  THE  WORK  OF  THE  CONFERENCE 
 Doc.  WAC/  158(  31.10.02) 


 Proposal  for  Resolution  801  Upgrade  Radiolocation  9  000-  9  200  MHz  and  9  300-  9  500  MHz  to  Primary 


 Agenda  Item  7.2:  to  recommend  to  the  Council  items  for  inclusion  in  the  agenda  for  the  next  WRC,  and  to  give  its  views  on  the  preliminary  agenda  for  the  subsequent  conference  and  on  possible  agenda 
 items  for  future  conferences,  taking  into  account  Resolution  801  (WRC-  2000); 


 Background  Information:  Working  Party  8B  is  conducting  studies  in  accordance  with  Question  ITU-R  226/  8,  titled,  Characteristics  of  and  Protection  Criteria  for  Radars  Operating  in  the 
 Radiodetermination  Service.  Working  Party  8B  has  also  developed  a  Preliminary  Draft  New  Recommendation  on  Characteristics  of  and  Protection  Criteria  for  Radars  Operating  in  the 
 Radiodetermination  Service  in  the  Frequency  Band  8  500-  10  500  MHz. 
 The  frequency  band  9  000-  9  200  MHz  is  allocated  to  the  aeronautical  radionavigation  service  on  a  primary  basis,  limited  to  ground-  based  radars  and  associated  airborne  transponders,  and  the 
 radiolocation  service  on  a  secondary  basis.  Also,  in  several  countries,  the  band  9  000-  9  200,  is  allocated  to  the  radionavigation  service  on  a  primary  basis  (5.473).  In  the  band  9  200-  9  500  MHz, 
 search  and  rescue  transponders  (SART)  may  be  used  (5.474).  The  band  9  300-  9  500  MHz  is  allocated  to  the  radionavigation  service  on  a  primary  basis,  and  to  the  radiolocation  service  on  a  secondary  basis. 
 Also,  in  the  band  9  300-  9  500  MHz,  the  aeronautical  radionavigation  service  is  limited  to  airborne  weather  radars  and  ground-  based  radars;  and,  in  addition,  ground-  based  radar  beacons  permitted  in  the 
 band  9  300-  9  320  (5.475). 


 The  9  000-  9  500  MHz  range  is  optimum  for  the  radars  due  to  antenna,  signal  propagation,  target  detection,  and  large  necessary  bandwidth  characteristics. 


 Airborne  radiodetermination  radars  currently  operating  in  these  bands  are:  search  &  track  radars,  search  radars,  ground-  mapping  &  terrain-  following  radars,  track  radars  and  surface  search  radars. 
 Shipborne  Radiodetermination  Radars  used  in  this  band  include:  search  &  navigation  radars  (shipborne  and  shore-  based),  track  radars,  low  altitude  &  surface  search  radars,  maritime  radionavigation  radars, 
 and  surface  surveillance  &  navigation  radars.  Beacons  and  Ground-  Based  Radiodetermination  Radars  are  currently  operating  in  these  bands  and  include:  rendezvous  beacon  airborne  and  ground  based 
 transportable  radars,  ground  based  transportable  tracking  radars  and  ground  based  transportable  precision  approach  and  landing  radars. 


 It  is  necessary  to  upgrade  the  radiolocation  service  to  primary  in  the  band  9  000-  9  200  MHz  and  9  300-  9  500  MHz  in  order  for  existing  and  planned  radar  systems  to  achieve  their  maximum  potential  and 
 perform  their  required  missions.  There  is  a  trend  towards  frequency-  agile  type  radar  systems  in  this  band  that  will  suppress  or  reduce  interference  and  requiring  larger  bandwidths  for  the  radars  to 
 function.  Emerging  requirements  for  higher  target  resolution  necessitate  wider  contiguous  emission  bandwidths.  An  upgrade  is  required  to  provide  radar  system  developers,  manufacturers  and  investors 
 confidence  that  their  systems  will  have  the  regulatory  assurance  to  operate  worldwide.

 Reasons:  To  provide  necessary  spectrum  for  existing  and  planned  radar  systems  to  operate  in  the  9  000-  9  500  MHz  range.
