HF STANAG Status

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

HF STANAG Status (cont’d)

• 4539 – Waveforms only 4 nations ratified, so not yet promulgated.

multiple implementations • 5066 – Datacomms – Planned edition 2: – Possible edition 3: Promulgated multiple implementations mandatory email protocol compliance w/4406 messaging LAN/WAN operations

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.”

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

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
