A new pair of optical wireless modems has been realized, which exploit Visible Light Communication (VLC) to transmit Ethernet signals through water. The modem prototypes are finally tested in sea waters at La Spezia harbor; they successfully transmitted 10 Mbit/s 10Base-T signals over a up to 10 m, notwithstanding the high turbidity and the strong sunlight. Final tests included the integration with SUNRISE testbed and the use with a moving robot, remotely operated. Commercial components were used to realize the modems; thus, we expect that the key design concepts can be used as a starting point for practical deployment of this technology.

Final tests included the integration with SUNRISE testbed and the use with a moving robot, remotely operated.
