Light bulbs as the new WiFi technology?

That's right, it looks like there're some guys at Boston University's College of Engineering working on low-power LEDs which could utilize an optical communication system to carry data wirelessly.

Using a technique which rapidly switches the LEDs on and off data transmissions could be made via imperceptible -- yet undoubtedly brain-scrambling -- flickering patterns, and each light would be its own network entry point at speeds of 1 to 10Mbps.

Why is this interesting? Well, as professor Thomas Little says: "Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires."

Looks interesting, doesn't it?
