MIL-STD Development Status• 188-110B 110B – Data ModemsPublished• 188-141B 141B – Radio & ProtocolsPublishedChange 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: Dt Data LikP Link Protocol• http://wireless.nmsu.edu/hf/standards/MIL//hf/ d d / /

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

188-141B 141B Notice 1: Appendix E• CFTP is now standardized for US interopDeployed in “5066” systems but notspecified in STANAG 5066• HF Mail Transfer Protocol (HMTP)Revised to match STANAG 5066Mandatory for interop with 5066 andfor future PKI architecture

HF STANAG Status• 4415 – Robust WF• 4444 – EPM• 4538 – ARCSPromulgatedMultiple implementationsPromulgatedGerman prototypePromulgatedgUS-UK-NL-NO air trialschairman: “stunning results”

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

NC3Board(AC/322–D/20)“By developing a modern, adaptive, andflexible HF system, much of NATO’smessaging, data, data link, facsimile and voicerequirements could be met within the HFband. This will reduce the demand for scarceSATCOM resources to those requirementsthat genuinely need large bandwidths.”

Power-Line Data Communications• Emerging home networking/broadbanddaccess technology in Europe• Operates in HF band; may raise noise floor• Netherlands commencing tests of powerlinecommunications interference with HF• Doesn’t appear economically feasible inNorth American power distribution system

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
