The lights are now dimmed throughout the many halls of CES, and none are more perturbed by darkness than the folks at Oledcomm. Illumination is the companys specialty, after all; or, more specifically, LiFi technology, which facilitates high-speed data transmission via pulsating light sources (though they appear static to the naked eye). We swung by the firms booth in Vegas to check out the various demos on display, including a two-way, 10 Mbps link tying a Macbook to a router.
