You Might Just Live Longer For a long time, med ical technology has lagged behind the rest of
the wireless world. Operating rooms do not allow Wi-Fi over radiation concerns, and there is
also that whole lack of dedicated spectrum. While Wi-Fi is in place in many hospitals,
interference from cell phones and computers can block signals from monitoring equipment.
Li-Fi solves both problems: lights are not only allowed in operating rooms, but tend to be the
most glaring (punintended) fixtures in the room. And, as Haas mentions in his TED Talk,Li-Fi
has 10,000 times the spectrum of Wi-Fi, so maybe we can, I dunno, delegate red light to priority
medical data. Code Red!
