Slow Wi-Fi could be completely eliminated by gigabit infrared light

Much as Wi-Fi is a marvel of modern technology, it also still really stinks. Two decades of development in, and we still can't consistently beam Netflix across a house in a consistent fashion. The standard for Wi-Fi is improving, sure, but one group of researchers thinks it should be replaced altogether. A PhD student in the Netherlands has come up with the concept to use infrared light for data transmission. The concept makes sense in physics terms, as light is more capable of transmitting high...
