US Navy Turns to Li-Fi to Tackle Russian Hacking

Ships will be able to transmit data with a beam of light from a common LED. The light is then received by a photodiode, which is able to decode the information. The technology, when used at sea, is in many ways similar to old navy equipment such as the Aldis lamp, which has been used to send Morse code messages via flashing light for over a hundred years. Li-fi technology has tested well at distances of up to one mile and it is believed that it could easily be used at a range of twelve nautical miles after further research. The technology is attracting increasing levels of attention as the internet service it provides has been proven to be faster than wi-fi. It is also, many experts believe, much more secure than wi-fi too.
