Lightbulbs to replace Wi-Fi?

— techdigest.tv — 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 ... (more) Lightbulbs to replace Wi-Fi?

Lightbulbs Could Replace Wi-Fi Hotpsots
textually.org — ... that would be faster and more secure than current network technology. "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," said BU Engineering Professor Thomas Little. This initiative aims to develop an optical communication technology that would make an LED light the equivalent of a Wi-Fi access point. [via Cellular News] ...

Light bulb networks could be the next WiFi
Engadget — ... If researchers at Boston University's College of Engineering have their way, light bulbs of the future may be the highway your data gets carried along. A team at the school is working on low-power LEDs which could utilize an optical communication system to carry data ...

Using LED lights to transmit data
Ubergizmo — ... line of sight. LED lights can flicker (hence creating 0 and 1 necessary to transport digital data) fast enough to be imperceptible by human eyes. The research team working on this project believes that wireless speeds of 1Mbps to 10Mbps can be expected when they get it to work. There's probably no real demand for this on the computers front, but other non-connected devices could be made to be connected this way. Think of it as Infra-Red data transmission with added "LED cool". [via cellularnews] ...

A Bright Idea: Wireless Data Transfer Through Light Bulbs
Wired: Gadget Lab — ... are aiming at the light technology at controlling household appliances, such as refrigerators, photo frames or printers -- bringing us a step closer to the dream of a wireless household. An LED wireless system would certainly eliminate clutter taken up by a traditional Wi-Fi or femtocell hub. But, as TechDigest also pointed out, I wonder if my shadow would interfere with wireless communication with a device? That would be slightly annoying, no?

Smart Lighting brings it all back to 1999
CrunchGear — ... Boston University, home of the Fightin’ Aristocrats, is working on “Smart Lighting” that includes LED lights and a optical networking adapter. Each light works as its own access point and can mesh together for full in-home coverage. Instead of transmitted radio waves, the system pulses an LED to all an sundry, ensuring that outsiders can’t piggyback on your network and reducing the costs associated with wireless transmission. While I thought optical ports had gone the way of the Dodo, it’s clear someone out there still thinks they’re a ...
