JHU APL Demonstrates Light-Based Communications Technology in Navy Experiment

Johns Hopkins Applied Physics Laboratory engineers demonstrated light fidelity or Li-Fi networking technology during a trip aboard the USS Carl Vinson.

The technology uses light-emitting diodes that turn on and off for more than a million cycles in a second to send data between wireless communication devices, JHU APL said Thursday.

The demonstration was part of the Navy's Trident Warrior 2018 experiment effort aimed at identifying and addressing the service branch's technological gaps in operational environments.

“The Navy wanted to see what the effects of shock and vibration would have on the wireless link and the equipment,” said Ryan Mennecke, communications engineer at APL.

JHU APL began studying light fidelity technology in 2016 under the Defense Information Systems Agency's interests, and is now helping DISA test and assess Li-Fi products.

The U.S. military is looking to apply Li-Fi technology to communications systems at vehicles and facilities.
