We’ve seen the light! Li-Fi is the future of wireless connectivity

Professor Harald Hass started researching this back in 2003, because he saw the upcoming spectrum crunch. He correctly predicted that the lack of radio frequency spectrum for mobile devices would become a real problem. (These days, it’s very difficult to get a connection on some Wi-Fi frequencies if you’re in an urban area.) Around the same time, new LED light technology hit the market, and Hass saw an opportunity to bring the two together. He found a way to use these electronic lighting components for high speed data communication, without interfering with existing radio frequency infrastructures. – Simon Hill, Digital Trends
