Folks at Boston University's College of Engineering are researching a program aimed at developing the next generation of wireless communication -- based on visible light.The aim of the initiative is to eventually develop an optical communication technology which would make an LED light, the equivalent of a Wi-Fi access point.
BU Engineering Professor Thomas Little paints the ideal scenario for these LEDs: "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..."
Additionally, as these networks work on the "line of sight" theory, it would be impossible to eavesdrop into a network by a person sitting across the wall. (more)
Humm...
• Light reflects.
• Fiber optics channel.
• Photocells convert.
• Appearance points can be tapped.
Impossible-to-eavesdrop type "progress" often brings with it info-vulnerabilities to be discovered. I can't wait. ~Kevin
Meanwhile, from the minds at MIT...
Talking-Lights.com "The Talking Lights System (using fluorescent lamps) can be used to form a hybrid network that combines the advantages of optical location-finding with broadband WiFi duplex data transfer... The systems can also be used to offer information and guidance to shoppers, museum-goers and trade show attendees, improve security in office buildings and secure facilities..."
Historical Note: Both LEDs and fluorescent lights are already being used for electronic eavesdropping bugging purposes.
