LIFI LIGHTFIDELITY CST 300 L Fall 2013 What

LI-FI (LIGHT-FIDELITY) CST 300 L Fall 2013

What is Light Fidelity? � Data communication through Light

How does it work? � LED lights � Orthogonal Frequency Division Multiplexing

Harald Haas explains how it works from: http: //youtu. be/Nao. Sp 4 Npk. Gg? t=4 m 40 s

Key Person � Professor Harald Haas, University of Edinburgh

�Advantages �Disadvantages �Means for Future

Advantages � Faster Data Speeds � More access to Internet � Use in areas where Data Communication is limited

Disadvantages � Cannot travel from room to room � Detector must face the source of light

Means for Future � Internet on Planes/Anywhere that uses Light � Saves Lives

Any Questions?
