  3. Contents • Scenario of Light house-to-ship using OCC • Challenging issues • Our demonstration • Other considerations • Conclusion

  4. Scenario of Light house-to-ship using OCC High power LED to blink data at far distance Rolling shutter camera with Zoom module Unidirectional OCC Data Data Driver module Asynchronous decoding Zoom module Rolling shutter picture Lighthouse LED Far-distance of transmission required. Asynchronous communication scheme is needed.

  5. Why using Zoom module Experimental test without Zoom with Zoom Higher SNR can be achieved => more far distance of transmission

  6. Challenging Issues Lighthouse transmitter Noise sources Light tail (Reflection by water surface) • Low SNR due to far-distance; Various noise resources • Light reflection and wave motion

  7. Our Demonstration Zoom module Zoom module is required (instead of increasing power) to achieve far-distance transmission

  8. 802.15.7r1 (Various) Our demonstration • Achieved Distance: 100m (using Zoom) • Achieved Link rate: 120bps

  9. Estimation of 1km transmission 1 km 100m 12VDC/15W LED panel: 1500W Camera position Size: 1.5m x 1.5m 15cm x 15cm Real LED lamp

  10. Other considerations Light house Variable FOV Buoy • Link switching to get seamless link • Variable FOV to transmit variable range

  11. 802.15.7r1 (Various) Conclusion • Need PHY to support asynchronous communication for unidirectional system • Need to have a link switching functionality • Consider far-distance transmission (up to km distance) such as scenario of light house-to-camera.
