Dartmouth researchers' 'DarkLight' enables visible light communication in the dark

(Dartmouth College) Through a new Dartmouth project called 'DarkLight,' researchers have developed and demonstrated for the first-time, how visible light can be used to transmit wireless data even when the light appears dark or off. As an example of the new wireless communication technology of 'visible light communication,' DarkLight provides a new way for wearables, smartphones and other smart devices to beam data, rather than relying on Wi-Fi or Bluetooth.
