Researchers at Boston University’s College of Engineering are working on a Wi-Fi replacement technology they shout “SMART LIGHTING” that sends input not via the radio spectrum, but the visible light spectrum. The concept is that standard dumb light-bulbs would be replaced by LED “smart lights,” which flicker at imperceptibly high rates as a way to transmit info within an office. Researchers believe initial speeds would hit amidst 1 and 10 megabits per second.
