Revised to match STANAG 5066
Mandatory for interop with 5066 and
for future PKI architecture

(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 powerline 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
