CST 300L 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: m40s

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
