Light and the Unexplored Communications Frontier
    Free-space optical communications stand to fundamentally change how humans use wireless networks. Whereas fiber-optic communications enabled the formation of the global network, free-space optical communication will facilitate the explosive growth of local, infrastructure-free networks. Leveraging LED bulbs, displays, phone screens, and other ubiquitous light sources, we can create scalable, local networks. These networks will not be used simply to gain Internet access, but rather, will be used to facilitate communication between humans and devices in an interactive way that cannot be achieved with RF. Light (and thus data) can easily be covered, focused, diffused, and directed - allowing the user a unique level of control regarding where and how data is sent. The shift from RF to optics is not an evolution, but rather a revolution in the way we think about wireless networking and device interaction.
