Will LEDs Replace Both Light Bulbs and Wi-Fi?

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