Lightbulbs to replace Wi-Fi? - Tech Digest
Researchers at the University of Boston have managed to come up with a way of transferring data through lightbulbs. It's not quite as crazy as it sounds - fiberoptics uses light to transmit data, but in a much more focused way. The researchers propose to use LEDs flickering at imperceptible speeds to communicate with network-enabled devices at speeds of between 1 and 10Mbps. Although that's not very fast for video streaming or online gaming, it's more than enough for an internet enabled fridge, photoframe or printer. Those kinds of devices are the target that these researchers are going after - bringing the digital home one step closer to reality...
