I did my first video about Li-Fi and about OLEDCOMM 5 years ago here it helped bring attention to this new technology, that basically functions a bit like Fiber light based data, but wirelessly. One LiFiMax access point and it’s USB receiver can transmit 100mbit/s download and 40mbit/s upload, using invisible light. Their system srefreshes the LED light in a pattern up to billions of times per second that can be recognized and read by the receiver wirelessly in a room. This can remove the issue of interference that there is with Wi-Fi, and the waves of this system may also be less harmful, more secure and perhaps more efficient than Wi-Fi.
