Oledcomm is a Parisian start-up which has spent the last two years working with “Li-Fi”: a “light fidelity”. At the heart of this technology is a new generation on high brightness light-emitting diodes. The solution consists on sending data through a LED light bulb that varies in intensity faster than the human eye can follow. Even using a basic modem connected to this bulb is enough to send information to the computer via a light sensor. These sophisticated techniques develop a speed intensity of over 500 megabytes per second which is already 150 times the speed of Wi-Fi connection.
