HF Radio Standards Development & NATO HF Working Group Report

1. HF Radio Standards Development & NATO HF Working Group Report January 2002 Eric E. Johnson Science Applications International Corporation & New Mexico State University eejohnson @ ieee.org

2. MIL-STD Development Status • 188-110B – Data Modems Published • 188-141B – Radio & Protocols Published Change Notice 1 delivered to IXMP 9/01 • Appendix C: Third Generation Protocols • Appendix E: Application Protocols (incl. E-Mail) • Appendix F: Anti-Jam/Anti-Interference • Appendix G: Data Link Protocol • http://wireless.nmsu.edu/hf/standards/MIL/

3. 188-141B Notice 1: Appendix C • Existing 3G protocols revised to match STANAG 4538 • 3G ALE dwell = 5+1 slots of 900 ms • NATO-Mode addressing • Added LDL packet sizes • Revised HDL sequence numbering

4. 188-141B Notice 1: Appendix E • CFTP is now standardized for US interop Deployed in “5066” systems but not specified in STANAG 5066 • HF Mail Transfer Protocol (HMTP) Revised to match STANAG 5066 Mandatory for interop with 5066 and for future PKI architecture

5. HF E-Mail Protocol Structure

6. 188-141B Notice 1: Appendix F • Anti-jam / Anti-interference Techniques • Updated to track changes in Appendix C

7. 188-141B Notice 1: Appendix G • Second Generation Data Link Protocolfor use with MIL-STD-188-110B modems • Now points directly to STANAG 5066:Annex A – Subnetwork Interface SublayerAnnex B – Channel Access SublayerAnnex C – Data Transfer Sublayer

8. NATO HF Radio Ad Hoc Working Group • Sierra Vista, AZ May 2001 • Koblenz, Germany November 2001 • Livorno, Italy June 2002

9. US – NATO Convergence Protocols 141B w/Notice 1 4538 3G ALE "Robust" Yes (5 slots)   Yes (5 slots)   "Fast" No Yes 3G ARQ LDL Yes Yes HDL Yes Yes 2G ALE Yes -> 141 2G ARQ -> 5066 supports 5066

10. US – NATO Convergence

11. HF STANAG Status • 4415 – Robust WF Promulgated Multiple implementations • 4444 – EPM Promulgated German prototype • 4538 – ARCS Promulgated US-UK-NL-NO air trials chairman: “stunning results”

12. HF STANAG Status (cont’d) • 4539 – Waveforms only 4 nations ratified, so not yet promulgated. multiple implementations • 5066 – Datacomms Promulgated multiple implementations • Planned edition 2: mandatory email protocol compliance w/4406 messaging • Possible edition 3: LAN/WAN operations

13. NC3Board(AC/322–D/20) “By developing a modern, adaptive, and flexible HF system, much of NATO’s messaging, data, data link, facsimile and voice requirements could be met within the HF band. This will reduce the demand for scarce SATCOM resources to those requirements that genuinely need large bandwidths.”

14. Power-Line Data Communications • Emerging home networking/broadband access technology in Europe • Operates in HF band; may raise noise floor • Netherlands commencing tests of power-line communications interference with HF • Doesn’t appear economically feasible in North American power distribution system

15. Other Projects • Ground Routing Protocol: ACP 193 • Initial work on video/image transfer over HF • Wideband data comms: • ISB modems as in MIL-STD-188-110B App F • Adaptive use of non-contiguous channel groups
