LED Lights: The Next Big Thing in Wireless Technology?
October 8th, 2008 by Ariel Schwartz
LED lights are more than an energy-efficient lighting alternative— they’re also a potential Wi-Fi replacement technology. Researcher at Boston University are working on Smart Lighting, a wireless technology based on visible light instead of radio frequency.
Data is transferred through the Smart Lighting system with LED light, so each light is essentially a Wi-Fi hotspot. Initial speeds of the network will be about 1 to 10 megabits per second, and data transmission will occur over existing electrical wiring.
And since LED bulbs are energy efficient, an LED wireless network will also be efficient—significantly more so than a radio frequency-based network. Additionally, since light doesn’t travel through walls or other opaque objects, chances of eavesdropping are lowered.
BU’s technology is still in the prototype stage, but it could potentially rival radio frequency networks for wireless dominance.
