Primary motivations are from Network Optional Warfare (NOW) operational concept to reduce vulnerability of surface and air platforms to RF intercept by hostile forces by using optical data channels.
FY17 NRP topic yielded Optical Messaging Tactical Decision Aid to include QR streaming, Digital Flashing Light (DFL), Signal Flags, Semaphore. Additional work identified Light Fidelity (LiFi) as a new capability and emerging standard for personal data communication, sharing similar characteristics as WiFi networking but without radio frequency (RF) transmissions.
Ongoing NPS research in NOW showed that optical data communications can reduce vulnerability of surface ships to enemy detection and intercept of radio frequency transmissions. From NPS-17-N091-C, significant work has been accomplished to demonstrate technical feasibility and tactical opportunities found in Quick Reaction (QR) Code and Digital Flashing Light (DFL) data transfer. An NPS-produced Optical Messaging Tactical Decision Aid (TDA) prototype includes 2-way QR code streaming plus operator support for DFL using Morse code, Signal Flags and Semaphore. Standalone disconnected tablets provide strong information security for potential shipboard use. Testing open-source software on ships and aircraft can show value in surface fleet scenarios. New Navy-sponsored commercial capabilities may further assist in automating onboard optical signaling paths.
Related work in progress is evaluating the applicability of Light Fidelity (Li-Fi) networking. Use of Li-Fi aboard ship has the potential to decouple personnel networking from sensitive shipboard networks, also reducing signal vulnerabilities afloat. At least two candidate implementations are available for further testing. Li-Fi seems well suited to below-decks networking in a cluttered metallic environment and technology is sufficiently advanced to merit ashore/afloat prototype experiments.
