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

2 MIL-STD Development Status B –Data ModemsPublished B –Radio & Protocols Published Change Notice 1 delivered to IXMP 9/01 –Appendix C:Third Generation Protocols –Appendix E:Application Protocols (incl. ) –Appendix F:Anti-Jam/Anti-Interference –Appendix G:Data Link Protocol

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

4 B 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 Protocol Structure

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

7 B Notice 1: Appendix G Second Generation Data Link Protocol for use with MIL-STD B modems Now points directly to STANAG 5066: Annex A – Subnetwork Interface Sublayer Annex B – Channel Access Sublayer Annex C – Data Transfer Sublayer

8 NATO HF Radio Ad Hoc Working Group Sierra Vista, AZMay 2001 Koblenz, GermanyNovember 2001 Livorno, ItalyJune 2002

9 US – NATO Convergence Protocols141B w/Notice G ALE "Robust"Yes (5 slots) "Fast"NoYes 3G ARQ LDLYes HDLYes 2G ALEYes-> 141 2G ARQ-> 5066supports 5066

10 US – NATO Convergence

11 HF STANAG Status 4415 – Robust WFPromulgated Multiple implementations 4444 – EPMPromulgated German prototype 4538 – ARCSPromulgated US-UK-NL-NO air trials chairman: “stunning results”

12 HF STANAG Status (cont’d) 4539 – Waveformsonly 4 nations ratified, so not yet promulgated. multiple implementations 5066 – Datacomms Promulgated multiple implementations –Planned edition 2:mandatory 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 B App F –Adaptive use of non-contiguous channel groups
