Flashing as in flashing your lights. Blinking. LED stuff. Crazy stuff, but it’s real. LVX System of Minnesota has installed wireless internet network in the form of blinking LED lighting system in a few office buildings in St. Cloud. The wireless building in these six city buildings come in the form that does not rely on the 802.11 standards, but more of flashing lights.

Still blur? Well, it’s like morse code, but it’s not. The flashing lights come on and off so quickly that they are imperceptible by the eye. The lights come from LED fixtures overhead, which also double as lighting for the city workers. The light fixtures consume about 36W and provide the same sort of illumination as a 100W fluorescent fixture. So, yes it acts as your light, and it also act as your wireless network.

Modems on desktops receive and transmit lights back up towards the lighting fixtires. Data bandwidth isn’t by any means great, as the current technology is only able to deliver about 3Mbps. Wi-Fi is much faster, but the lighting method is more secure and less prone to interference.

Though, there’s one thing that I learn from Physics class, is that lights that exist by flashing very fast, your brain does not notice the extremely fast on and off. However, you eye will still feel it, and if the speed of the blinking is somewhat slow, it’ll tire your eye down, thus making you sleepy. That’s why nobody uses these lamps as study lamp.
