I just read in Scientific American that LEDs that are used for househould lighting can be simultaneously used for wireless broadband. They flicker on an off very quickly transmitting 1’s and 0’s, faster than a human eye can see. And because light can’t go through walls, it’s more secure 🙂 It’s also very fast.
