WP9C Mission

• WP9C is the ITU-R group that deals with HF
  Fixed Service. In fact, it also addresses many
  other HF communication issues, even
  Maritime-Mobile and Aeronautical-Mobile.
• Recent activity has dealt with
• Adaptive HF Handbook
• Channel Simulation
• Dynamic Frequency Management
• Modeling and Prediction Issues
• Spectrum Issues

Membership in USWP9C

• Anyone who has an interest
• Current members (active )
• J.M. Goodman ()
• George Lane ()
• Eric Johnson ()
• Robert Jensen
• Steve Elvy
• Dave Murotake
• Ken Wickwire
• Jim Hoffmeyer
• William Rummler
• Dan Roesler

Urgent Call for Additional Active Members in
USWP9C

• To work on some current issues that may be
  relevant to the direction of adaptive HF system
  development or ALE technology exploitation
• To examine technologies that are being considered
  for sanction or standardization within ITU-R
• ITU-R Recommendations can be useful (or harmful)
  to USA commercial interests
• The ITU-R working groups plays a key role in the
  modification and clarification of the Radio
  regulations
• Contact John Goodman jm_good_at_cox.net

WP9C WP3L Synergy

• WP9C deals with HF systems
• WP3L deals with propagation, modeling and
  prediction

6
Agenda at Recent April 2002 Meeting of WP9C in
Geneva

• Handbook on Adaptive HF Systems
• Review of Rec. ITU-R F.1110
• Simulation of the HF channel (joint with WP3L)
• Review of Questions assigned
• Liaison with other organizations in ITU-R
• Review of input documents
• Establishment of other sub-working groups

7
HF Handbook Chapters

• 1. Introduction
• 2. The Radio Regulatory Framework
• 3. Adaptivity Techniques
• 4. Propagation Environment
• 5. System Engineering
• 6. Use of Sounding and Channel Estimation
  Techniques
• 7. Control, including ALE and ALM, taking into
  Account Systems in use or Standardized
• Annex 1 An Example of a Managed HF Network

8
DNR on Prediction Method for Adaptive HF System
Planning and Operation

• The DNR was approved by WP9C in April, and is
  likely to be approved as a new ITU-R
  recommendation (shortly).
• It basically embraces existing ITU Rec. P.533,
  but recommends consideration of the ITS suite of
  programs (e.g., VOACAP, ICEPAC, and Rec533
  models) for use in adaptive HF system planning
  and operation.
• This was based upon a view that some deficiencies
  in I/O and methodology may exist in ITU-R Rec.
  P.533
• The DNR was brought to the attention of WP3L.
• WP3L send WP9C a liaison statement asking WP9C to
  send them a list of output parameters needed from
  an updated REC533 so that they may advise WP9C
  appropriately.

9
Liaison Statement from WP3L to WP9C on Optimum
Operation of HF ALE Systems

• WP3L submitted documentation in its May 2002
  meeting that it wishes to be brought to the
  attention of WP9C is a possible revision of
  F.613.
• ITU-R Rec. F.613 is On the Use of Ionospheric
  Channel Sounding Systems Operating in the Fixed
  Service at Frequencies Below about 30 MHz.

10
REQUEST

• That HFIA membership engage in the work of the
  ITU-R, including WP9C and WP3L. There is
  interesting work to do, and much has a bearing on
  the interest areas of the HFIA
• The work includes participation in several
  meetings this year (2002) in WDC in preparation
  for subsequent meetings in Geneva (2003).
• For USWP9C contact J.M. Goodman
  (jm_good_at_cox.net) For USWP3L contact Eldon
  Haakinson (ehaakinson_at_bldrdoc.gov)
