Using light to move wireless data faster - Science Nation

The video explores the challenges of increasing wireless data traffic due to the proliferation of devices. Xia Zhou and her team at Dartmouth College are developing visible light communication as an alternative to radio frequency, offering wider bandwidth and enhanced security. The technology can transform LED lights into wireless transmitters, even when they appear off, through dark light technology. Additionally, the team is working on using light for behavioral sensing, allowing interaction with devices via gestures. Eye-tracking technology is also being developed for future applications. The video concludes with the potential of visible light communication to meet future wireless data demands.

Explain the concept of 'dark light' as mentioned in the text.

What future advancements do Zhou and her team foresee with visible light communication?
