Abstract
Systems and methods for visual light communication in an underwater environment are provided. The system can include a master control station that determines an amount of impairment of a water medium and selects one of a wired and wireless communication transceiver for exchanging communications with communication device located in the water. The system can also include a first gateway that exchanges radio frequency signals with the master control station and provides visual light communication signals to devices located in the water. The system can also include a second gateway that can exchange both visual light communication signals and acoustic communication signals with other devices located in the water.
