Li-Fi – Transmitting Data Through LED Bulbs

Is Li-Fi, a method of transmitting data wirelessly using LED, the answer to the world’s problem of congested bandwidth?
What if every light bulb in the world could also transmit data? Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread.
